There are five oceans on Earth. Each ocean leads into the next, creating one huge expanse of water, covering 71 percent of Earth's surface.
The smallest ocean is the Arctic Ocean, with an area of 5,880 sq. mi. (9,485 sq km).
The Pacific Ocean is by far the biggest ocean. It covers nearly one-third of Earth's surface!

how can astronomers predict variations in length and strength of solar flares
Answer:
Solar flares are massive explosions of energy in the Sun's atmosphere.
The new technique allows changes in the Sun's magnetic fields, which drive the initiation of solar flares, to be monitored up to ten times faster than previous methods.
Which layer where meteors, or shooting stars burn up?
Meteors, often called shooting stars, burn up in the mesosphere layer of Earth's atmosphere due to heat from friction with atmospheric gases. Larger meteoroids may reach Earth's surface as meteorites, potentially forming craters. Most meteors vaporize before reaching the ground.
Meteors, commonly referred to as shooting stars, are not stars at all. Instead, they are tiny masses of cosmic dust or broken rock that enter Earth's atmosphere from interplanetary space. The layer of Earth's atmosphere where most meteors burn up is the mesosphere. As these meteors streak through the mesosphere, they encounter friction with the gas molecules, which causes them to heat up dramatically. This intense friction and heat cause many meteors to vaporize, producing the brief flash of light we see from the ground.
Occasionally, larger meteors or meteoroids may survive the journey through the mesosphere and reach the Earth's surface; these are termed meteorites. If a meteorite hits the Earth, it can create an impact crater, depending on its size, density, and speed upon impact. However, most of these interplanetary particles are small enough to burn up completely before reaching the ground.
Ocean continental convergence produces____?
Explanation:
Ocean-ocean convergence is a process that takes place in deeper oceanic plates, which are lying deeper in the oceans. When these plates converges it results in subduction which means deposition of materials when the edges of the two plates convergence the sediments are deposited beneath the ocean. These heavy sediments affects the magma and generates energy sufficient to cause volcanic eruptions. The volcanic eruptions results in the formation of mountains as above the magma there are many layers of sediments which develop into mountain.
Answer: Mainly volcanic mountains
Answer:
Mainly Volcanic Mountains.
Explanation: There is no explanation to the answer it is a simple fact that you can research.
What is Ocean continental convergence?-This type of convergent boundary happens where an oceanic plate and a continental plate push together causing the oceanic plate to be forced under the continental plate into the mantle because the oceanic plate is thinner. This is called a subduction.

How did ptolemy account for retrograde motion in his model of the solar system
Answer:
Ptolemy accounted for 'retrograde motion' in his model of the solar system by introducing smaller circles named 'epicycles'.
Explanation:
According to Ptolemy, the Sun and the other planets in the Solar system orbited around the Earth. The Greeks were convinced that Ptolemy's earlier model did not provide for backward or the retrograde motion. Ptolemy thought over it for a while and theorized the possibility of 'epicycles'. According to Ptolemy, the planets that orbited Earth also orbited another smaller point. The smaller orbits followed by the planets while in motion around the Earth in a larger orbit were introduced by Ptolemy as 'epicycles'. Until Kepler proposed his models of the functioning of the Solar system, Ptolemy's models were considered the most relevant.What replaced communist tyranny in Russia and Central Asia?
After the fall of communism, Russia became a democracy, at least on paper, and the same case is with Central Asia, and again, at least on paper. While these countries declare themselves as democratic ones, that is not the case in practice. Russia did tried some version of democracy, but it didn't seemed to work and actually caused more of a mess in the country. Putin used that, got to power, and ever since then he is either the president or shadow president of the country, being a modern day version of a softer dictator. Central Asia on the other hand, pretty much continued the same way, just that it is more of a nationalistic dictatorship instead of communist one. The leaders of these countries tend to be absolute leaders, often being very cruel and restrictive, holding their countries in their palm.

Which of these is an example of interregional migration? A) migration between countries B) migration flow within Mexico C) migration between continents D) migration flow within New York City
Answer:
B) migration flow within Mexico
Explanation:
The interregional migration is a migratory pattern that occurs inside a country, or rather from one region of the country to another of its regions. This happens in pretty much every country in the world, where people choose the most attractive places in the country as their future home, as they offer some advantages when it comes to their professional development, finances, higher standard of living. In a country like Mexico, the majority of the interregional migration is between the countryside and the large cities, especially the capital Mexico City. The reason for this is that the people in the rural areas are much more limited in their opportunities and they live in poverty in general, while the large cities are well developed and they offer lot of opportunities for better careers and life.
What are the three parts of an emergency preparedness plan to a tornado?
Answer:
Planning
An underground area, such as a basement or storm cellar, provides the best protection from a tornado. If an underground shelter is unavailable, consider the following:
Seek a small interior room or hallway on the lowest floor possible
Stay away from doors, windows, and outside walls
Stay in the center of the room, and avoid corners because they attract debris
Rooms constructed with reinforced concrete, brick or block with no windows and a heavy concrete floor or roof system overhead
Avoid auditoriums, cafeterias and gymnasiums that have flat, wide-span roofs.
Answer:
Planning
Equipping
Training
Explanation:
Planning:
You can't ever plan for a tornado. You never know when one is going to pop up in your front yard, so you can't plan for it. However, you can plan for what to do if one does happen. By planning an emergency route and a routine specifically for a tornado, this will increase your chance of survival.
Equipping:
Being equipped for a tornado is very important. If a tornado were to knock out your power, electricity, heat, water, etc. then what would you do? You couldn't do anything if you weren't properly equipped, and that is why it is important to always be equipped. Flashlights, batteries, water, paper towels, etc. Always be sure to pack the necessary emergency items needed to survive for a day, or maybe even a week.
Training:
Like I said in step number one, you can plan for what to do if a tornado strikes. Have a routine ready for what you were to do if a tornado were to hit, and practice a training course. By practicing what to do, if one does happen, your brain would recognize this and you would have a chance or surviving. Plan an escape route, what to grab, what not to, who to bring alone, then practice it before hand.

Tax reduction, New workplace creation, Increasing food supplies are the strategies to influence the population.
Explanation:
There are many strategies that a country may use either to increase or to decrease its population.
Reducing taxes for the people who have less number of offspring’s would result in the decrease of population. Making people to pay if they have more than a certain number of children is another way to decrease population. The people in a country may be willing to reproduce, when the country increases food supplies. A country can create new workplaces those results in increasing population.What are Mali's major industries? What are the risks of these industries?
Answer:
Agriculture and livestock, mining, construction
Explanation:
Mali is a low developed country, and its industry is still on a very low level, being responsible for only between one quarter and one fifth of the GDP of the country. The majority of the industry in Mali is based around the agriculture and livestock, thus manufacturing and processing food, with the mining, mostly of gold and phosphates, and the construction being the other two, though less important. The big risks on having this type of industry are that it is heavily dependent on the nature, mostly the weather conditions. If the weather conditions are not right in one year, it can make a big blow to the economy.
Cultural convergence is _____.
is sparking a range of social, political, economic and legal disputes because of the conflicting goals of consumers, producers and gatekeepers. These contradictory forces are pushing both toward cultural diversity and toward homogenization.
Cultural convergence is a mixture of cultures.
Explanation:
Convergence of cultures is the theory that two cultures become more and more similar as their interaction increases. In short, the more cultures interact, the more of their values, ideologies, behaviors, art and habits begin to reflect. So it is basically called as a ''mixture of cultures''.
The conception of convergence is a mixture of two different entities, and in the context of ''technology'' and ''computing'' for blending of two or more different technologies in one device or system.

Explanation:
Each photo shows an example of weathering and erosion. Match each photo with the element that caused the weathering and erosion. Match each with either water, vergetation, oxygen wind. Find the pairs. Thank you
Explanation:
First picture (solo structure in desert): Wind. The wind has sculpted this by throwing grains of sand to the structure... it's a natural sandblasting job.
Second picture (rock and sea): Water. The constant waves hitting the rocks are sculpting and eroding it. I suspect some freezing and thawing (still water) was also into play.
Third picture (roots): vegetation. The roots of trees are very powerful and they'll destroy anything on their path seeking water.
Fourth picture (white and red): oxygen. That's a rusty piece of metal, the red comes from the oxydation, meaning blend of the metal with oxygen.
Weathering and erosion in photos can be matched to elements like water, wind, oxygen, and vegetation. Indications of water could be smooth stones or carved valleys, wind might show sand dunes or cracked soil, oxygen is shown by rust-colored rocks, and vegetation might manifest as roots breaking rocks or soil held by grass.
Explanation:To answer your question about matching the photos to the elements that caused the weathering and erosion, it’s important to understand what each element does.
Water causes weathering and erosion by gradually wearing away rocks and soil in a process known as hydraulic action. If the photo shows smooth, rounded stones or deep valleys carved out by a river, then water is the likely culprit.
Wind can cause erosion by picking up and carrying loose particles of dirt and dust. If the photo shows sand dunes or areas with rough, cracked soil, it likely demonstrates wind erosion.
Oxygen causes weathering through a process called oxidation, which breaks down rocks. It's difficult to identify from photos, but often can be inferred from the presence of rust-colored rocks.
Vegetation can also contribute to both erosion and weathering. It can cause weathering as plant roots grow into rock cracks, breaking them apart. If the photo shows tree roots breaking through rocks or a layer of soil held together by grass, it likely shows the effects of vegetation.

Explanation:
compared with warm fronts,cold fronts are A: faster moving B: less dense C: more cloudy or D: less steep
Answer:
A: faster moving
Explanation:
The cold fronts are air masses that are cold. They tend to be dense, cold, and dry. These fronts are also much steeper than the warm fronts. The cold fronts are much more powerful than the warm fronts, which is mostly because of their higher density. They managed to move much quicker, to push the other air masses out of its way, and to pass much longer distances than any other type of front. As the cold fronts are moving quickly, they are able to cause drop in the temperature of up to 15 C degrees in only one hour.

the process in which rock fragments freeze to the bottom of a glacier and then are carried away when the glacier moves is called.
Answer:
Plucking
Explanation:
Plucking is a glacial phenomena that is responsible for erosion and transfer of rocks in glacier. This occurs in the valley glacier. As a glacier moves down a valley the friction causes the ice present at the base of the valley glacier to melt and the joints of the rocks breaks. Friction has an thawing action on the ice of valley glacier and on the rocks situated at the bottom. Large pieces of rocks come out of ice and gradually they get separated from each other. Loose rocks are carried away by the glacier as it moves.

Explanation:
Sustainable activity
sustainable development is “development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Examples are as follows:
sustaining the potential of natural and physical resources (excluding minerals) to meet the reasonably foreseeable needs of future generations; and
safeguarding the life-supporting capacity of air, water, soil, and ecosystems; and
avoiding, remedying, or mitigating any adverse effects of activities on the environment
Basically farming & fishing do not compromise the ability of future generations to meet their own needs. But mining a minerals (which have a limited supply) will compromise future generations.
Mining for minerals activity is not a sustainable human activity. option (C) is correct.
What is a mineral?A mineral is a naturally becoming unstructured element or compounds having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, felspar, mica, mineral, olivine, and spar.
Development that satisfies current demands without compromising the capacity of future generations to satisfy their own needs is referred to as sustainable development. Following are some examples

. a situation in which population exceeds an area's ability to provide necessary services
Answer:
Overpopulation
Explanation:
Overpopulation is a situation in which population exceeds an area's ability to provide necessary services. This leads to a poor standard of living and abject poverty.
Every environment or region have a carrying capacity and if exceeded, there is tension on available resources.
Factors that leads to overpopulation are:
>Immigration: immigration is the movement of people from one place to another. This could be as a result of war or in search of better opportunities.
>High birth rate: when birth rate is not properly checked, a spike in population can occur. This can greatly tip the balance in the carrying capacity of an environment.
> Low death rate: if mortality decreases due to good health facilities, population would increase.

What phenomenon is responsible for hot spots
A. Mantle Plumes
B.Pyroclastic Flow
C.Ridge Push
Subduction
Answer:
A. Mantle Plumes
Explanation:
The phenomenon is responsible for hot spots is Mantle Plumes.
Explanation:
Volcanic activity that is completely unrelated to the plate movements or boundaries and takes place within the tectonic plates is termed as hotspot volcanism. Mantle plumes are basically the lighter and warmer mass inside the mantle that comes up as a result of the process of convection.
It has a head like a bulb followed by a long tail. When the head reaches the lithosphere, it spreads out like a mushroom. During this process, the pressure drops down while the temperature stays constant resulting in decompression melting of the mantle, producing huge amounts of magma.
Which of the following lists the correctrequirements for a black hole to form?
A. The star must be 29 times larger than Earth's sun, and a supernova explosion must have occurred. B. The star must be 10 to 28 times larger than Earth's sun, and a supernova explosion must not have occurred. C. The star must be 10 to 28 times larger than Earth's sun, and a supernova explosion must have occurred. D. The star must be 29 times larger than Earth's sun, and a supernova explosion must not have occurred.
Answer:
A
Explanation:
Formation of black holes occur during the death of massive stars (at least 25 times larger than Earth’s sun). When the fuel of the massive star is exhausted, the star’s nuclear forces are unable to counter the gravitational collapse due to its own weight. The star dies in a supernovae and the remnant is a black hole.
Answer:
A. The star must be 29 times larger than Earth's sun, and a supernova explosion must have occurred.
Explanation:
The object has a strong gravitational force. Usually, a black hole has an enormous gas with an overall structure that is present in space. When determining the physical appearance, then it is about 28 times bulky and massive when comparing it with the sun. Therefore energy is pulled by the black hole from the surrounding galaxies.
The black holes are amazing because they have invisible beats that pass through the scatter forming a cosmic object that continues to captivate the explosions.
