Describe the causes of surface and deep ocean currents
Answer: The causes of ocean currents include wind, water temperature/salinity and natural disasters.
Explanation:
A current or circulation is the unified movement of water across the ocean. A Surface current affects the topmost layer of seawater and is defined by the direction of the wind while Deep Currents reach the sea floor though a combination of surface currents and landforms.
Water temperature and salinity cause currents by changing water density which in turn results in deep ocean currents circulating the seawater.
Other conditions that cause strong currents are storms and earthquakes which introduces particles into the seawater.
Answer:
a. Wind is the major cause of surface ocean current
b. Thermohaline circulation is the major cause of deep ocean current
Explanation:
Ocean currents is said to be the redistribution or movement of water bodies from one point to another.
On a wide scale the major forces or causes behind the ocean current on the surface is wind-driven. The ocean water on the surface and the atmosphere is directly heated by the sun and it produces winds which blows over the ocean surface , transmitting energy through the process resulting to waves and current.
On the other hand the major causes of deep ocean currents is the Thermohaline circulation . This exist due to temperature and salinity(salty) variation . Usually, water having lower temperature (cold) and high salinity content possesses higher density than high temperature (warm) and low salinity content water respectively. The higher density water sinks deeper. The density variation is the major driving force behind deep ocean current in an extensive scale. And this is what we call the Thermohaline circulation.
All of the following issues involve environmental science except a. measuring smog levels in cities. b. asking people questions about the cost of various resources. c. studying the loss of plant and animal species. d. publishing the results of a study on fossil fuel depletion.
All of the following issues involve environmental science except asking people questions about the cost of various resources. Hence, option B is correct.
What is the cost of various resources?The term “resource cost” refers to a fixed or variable cost for the use of resources as required by the various project activities. A cost resource enables a person to apply a cost to that activity by designating a cost item such as an investment in equipment or variable expenses like travel or lodging, to that task.
In contrast to fixed costs, a person can use as many cost resources as you wish for a task. In Microsoft Project, resources come in three different forms: work, costs, and materials.
Work resources manage the assignment of labour and equipment, cost resources manage the assignment of specific costs like travel, and material resources manage the assignment and tracking of the materials used for the project.
Thus, option B is correct.

The amount of radiation we personally encounter that originates in the Earth's and the atmosphere's natural background is?
Answer: More than half
Explanation:
The amount of radiation we personally encounter that originates in the Earth's and the atmosphere's natural background is more than half.
The reason is, since natural sources of background radiation include: cosmic rays, that is, radiation that reaches the Earth from space; rays from rocks and soil, that is, some rocks are radioactive and give off radioactive radon gas; rays from living things, like some plants absorb radioactive materials from the soil and these pass up the food chain.
And the main source of exposure for most people is naturally-occurring background radiation. Levels typically range from about 1.5 to 3.5 millisievert per year and can even be more than 50 mSv/yr.
From the above information therefore, the amount of radiation we personally encounter that originates in the Earth's and the atmosphere's natural background is more than half.

"Flat-lying sedimentary strata or volcanic rock layers may erode to form isolated structures called"
Final answer:
Isolated structures formed from flat-lying sedimentary strata or volcanic rock layers by erosion are called monadnocks or inselbergs, which are resistant to weathering and provide geological insights.
Explanation:
Flat-lying sedimentary strata or volcanic rock layers may erode to form isolated structures called monadnocks or inselbergs. These formations are a result of the erosion of surrounding softer materials leaving the more resistant rock layers exposed as prominent, isolated structures. The structures give insights into the geological past and can indicate the presence of ancient mountain ranges or plateaus that have since been worn down through weathering and erosion while the harder monadnocks have resisted these forces.

What happens to weather when warm air from the gulf of Mexico meets the cooler land air over Florida?
Answer:
Thunderstorms and hurricanes.
Explanation:
The warm air mass expands and it roses slowly and it forms the cumulonimbus clouds and thus they develop on to thunderstorm and give raindrops. The Gulf of Mexico is a major interaction in the development of the tropical storms and thus is tracked to the coast of Mississippi regions.Human migration and global trade are two factors that have altered geographic distribution of parasites. One result of this phenomenon is that humans are introduced to new infections more often, and they can be co-infected by several parasites from different species or lineages. These co-infections can result in matings between individual parasites of the different species and lineages. What biological diversity concept does this phenomenon provide evidence for?a) hybridization of species, specifically parasites
b) ecological niches
c) reproductive barriers
d) geological barriers
Answer: a) hybridization of species, specifically parasites
Explanation:
Hybrid speciation is a kind of speciation that is caused by reproductive isolation from the parent species. In this the hybridization occurs between the two different species which leads to the formation of new species.
The hybrid formed because of the hybridization of the species that belong to the same genus called as interspecific hybrids and those formed between different sub-species are called as intra-specific hybrids.
Here, in the given situation, the hybridization of the different species of parasites due to geographical distribution of parasite due to global trade has resulted which is responsible for co-infections.

Are there any specific gestures that traditional Chinese people make when they are saying"I'm sorry" to an elder?
(Optional but 100% Brainliest)
Also, could you provide some information on traditional Chinese culture?
Thank you mates!
Traditional Chinese culture is something so wide and variational that it is hard to write about. China was suspect to Civil War so often in ancient times that entire ethnic groups and people’s were wiped out of existence, only for them to spring back into existence a few years later. Although this is the case, there are some customs and umbrella terms under traditional Chinese culture.
Buddhism is something that China all throughout its history has had wide popularity. It is something that one may see almost everywhere they go when touring the place. Another popular traditional Chinese culture is Taoism or The Way, which started as simply a way to live life, but transformed into, maybe because of Buddhism, a full-fledged religion. Confucius, the 5 virtues of a good government, also is a large part of traditional Chinese culture and is one of the reasons that the Communist government of China is so widely popular among the Chinese themselves (until recent years) especially to the older generations. Those are the main points I saw in traditional, non-westernized Chinese culture.
When saying, “I’m sorry,” to anyone in Chinese culture, there are several ways to apologize to to them, but body language-wise you should do a motion similar to waving with both your hands as well as bowing you head while apologizing. This is more commonly done which people of similar ages though. Another motion you can do is holding your hands in front of you and bowing your head or nodding your head. That’s the best explanation I can give in that respect.
Sediments derived form preexisting rocks are called:________.
a. volcagenic.
b. lithogenous.
c. hydrogenous.
d. biogenous.
e. cosmogenous.
Answer:
b. lithogenous.
Explanation:
Generally, sediments are formed from preexisting rocks, it might be igneous , metamorphic or even sedimentary rocks . As earth processes(weathering, erosion and wind ) takes place this rocks are broken into smaller particulate matter to form sediments. Sometimes this rocks can form an entirely new substance due to chemical weathering. Some of this sediments are driven into the sea through erosion and wind.
Lithogenous sediments are preexisting rocks formed from the land . They are also known as terrigenous rocks. Sometimes due to erosion and weathering, some of this sediment might find their way to the ocean floor .
Due to the mode of formation or earth process that forms this lithogenous sediments the texture and sizes varies. Some of the particulate matter are fined and tiny while some are coarse and rough in texture.

Yes, that's correct. When the president is not on board, Air Force One is commonly referred to simply by its aircraft type or military designation, such as "Boeing VC-25" or just "VC-25." Thank you for clarifying! If you have any more questions or need further assistance, feel free to ask.
Heterozygote advantage is a condition where heterozygotes have a higher fitness than homozygotes. In this scenario, the value of 2pq, which represents the frequency of heterozygotes in the population, would likely increase under heterozygote advantage.
Looking at the results of the field experiment provided, both trials 1 and 2 show evidence of heterozygote advantage. Survival rates of Aa individuals are higher than expected based on the allele frequencies.
Therefore, the correct statement based on the results is that both trials 1 and 2 show heterozygote advantage as indicated by the increased survival of the Aa individuals.
In North America, native pollinators often increase the quantity and quality of crops of native plants that are insect-pollinated more effectively than European honeybees do. The most likely reason for the phenomenon is that native pollinators _____________.
Answer and Explanations:
The reason is because native pollinators e.g native bees are messier than honey bees and often don’t have tidy pollen pouches on their legs and this makes them better at spreading pollen around thereby increasing the quantity and quality of crops of native plants.
Also, native bees tend to shake more loose. As a matter of fact, tomato farmers could see 50% more tomatoes that are twice as big if they get regular native bee visits like bumble bees.
____________________ energy resources are replenished by natural processes as we use them
Answer:
Renewable energy resources are replenished by natural processes as we use them
Explanation:
Renewable energy are energy sources that gets replenish naturally even after excessive usage overtime. This energy resources are never depleted, nature and the earth finds a way of constantly supplying this source of energy. Examples of these renewable energy are wind, sunlight(solar), geothermal heat, water(hydroelectric) and tides .
The renewable energy sources generally reduces emission of green house gases that destroy the environment. Unlike the non renewable energy sources such as fossil fuel, Renewable source of energy are very clean source of energy.
The sun provides radiation on the earth surface and technologies are use to convert this energy into usable form. In the case of wind the energy from the wind are been converted using large turbines.
In the case of water, through water cycle the earth make sure water is been constantly supplied. The energy from water(hydropower) are converted to power homes and other facilities.
If the lithology and fossil content of two bodies of rock on opposite sides of a canyon are identical, then these remaining outcrops were likely physically connected at one time and formed part of an extensive, sheet-like layer of rock. This idea summarizes the principle of_________ .A. superpositionB. original continuityC. original horizontalityD. uniformitarianism
Answer: B. Original Continuity
Explanation:
Original continuity is the concept that sediments are deposited horizontally at the original point of formation. This lateral deposit continues, layer by layer unless the sediments are interrupted by a barrier.
The two rocks on the opposite sides of the canyon were likely one body of rock due to their similar lithology and fossil content. It is likely that the canyon formed due to erosion over time, thereby creating a barrier between the rocks.
The idea that two bodies of rock on opposite sides of a canyon with identical lithology and fossil content were likely physically connected at one time is summarized by the principle of original continuity, also known as the principle of lateral continuity.
Explanation:If the lithology and fossil content of two bodies of rock on opposite sides of a canyon are identical, then these remaining outcrops were likely physically connected at one time and formed part of an extensive, sheet-like layer of rock. This idea summarizes the principle of original continuity.
The principle of lateral continuity suggests that layers of sedimentary rock were once continuous, and anything that interrupts the layer (like a river or canyon) occurred after the rocks were deposited. This principle is employed when geologists compare seemingly similar groups of rocks separated by some distance. They can infer that rocks on either side of a canyon were, in fact, the same and were once connected before the canyon formed. Thus, identifying identical lithology and fossil content across these divides provides evidence for this continuous nature prior to any geological separation.
If you could count stars at a rate of about one per second, how long would it take to count all the stars in the Milky Way Galaxy?
Answer:
It could take several thousands of years.
Explanation:
To be specific, the exact number of stars in the galaxy is unknown, it's estimated to have around 100 to 400 billion stars.
But for the sake of this test, let's take as valid a recent study of the European space agency, that believes that we have 100 billion stars orbiting our galaxy.
If you could count 1 every second it would mean you'll need at least 100 billion seconds to do it. How many days is that?
We have:
100 billion seconds = 1.666 billion minutes
1.666 billion minutes = 27.777 million hours
27.777 million hours = 1,157 million days = 3,170 years.
You would need at least, 3170 years of spare time, considering that you will do no other thing than counting stars for the next 3 millennia.
If you could count stars at a rate of one per second, it would take roughly 3,178 years to count all the stars in the Milky Way Galaxy. This calculation is based on a lower end estimate of 100 billion stars in our galaxy.
Explanation:If we consider a rough estimation of the number of stars in the Milky Way, it's often proposed to be about 100 billion. However, some estimations go up to 400 billion. Let's stick with the lower estimate for the sake of this calculation.
If you were to count the stars at a rate of one per second, it would take you 100 billion seconds to count them all. But how long is this in more understandable time units?
There are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day. So 100 billion seconds is equal to 1.65 billion minutes, 27.8 million hours, or 1.16 million days.
Now, there are 365 days in a year, so 1.16 million days is roughly equivalent to 3,178 years. That's how long it would take you to count each star in our galaxy, assuming you could do this non-stop without breaks for sleep, meals, or anything else.

Characteristics of passive continental margins include which of the following? a.Volcanic and earthquake activity b.Broad continental shelves c.Chains of islands d. Deep-sea trenches e.Thin sediment accumulation
Answer:
(B) broad continental shelves
Explanation:
Passive continental margins have broad continental shelves
Many passive continental margins have a continental rise, a very low‐angle ridge of sediment that forms between the continental slope and the abyssal plain.
Passive continental margins are characterized by broad continental shelves and thin sediment accumulations, with a noticeable lack of tectonic activity like earthquakes or volcanoes. They don't feature chains of islands or deep-sea trenches.
Explanation:The characteristics of passive continental margins include mainly vast, broad continental shelves and thin sediment accumulation. Unlike active continental margins, passive margins are not associated with plate boundaries, so they do not witness much volcanic or earthquake activity. They do not have chains of islands or deep-sea trenches. These features - chains of islands, deep-sea trenches, volcanic and earthquake activity - are characteristic of active rather than passive margins. Passive continental margins are typically marked by a lack of tectonic activity, broad, gently sloping shelves, and thick accumulations of sediment eroded from the adjoining continent.
