The evolution of photosynthetic life alters Earth's atmosphere as Hydrogen moves to the top of the atmosphere and most of it escaped into space.

The molecules of gas generated after the process of photosynthesis process rapidly move out of the Earth's gravity and goes to space.

Therefore, Earth tends to hold its original atmosphere which is made up of hydrogen and helium.

The evolution of photosynthetic life led to an increase in atmospheric oxygen, reduction in CO2 levels, and the formation of an ozone layer, which allowed for more complex life forms to evolve on Earth.

The evolution of photosynthetic life forms, such as cyanobacteria, dramatically altered Earth's atmosphere. Initially, the atmosphere was anoxic, containing no molecular oxygen, and only anaerobic organisms could live. However, once photosynthesis began, these organisms released oxygen as a by-product. Over time, the accumulation of oxygen led to significant changes, including the development of an ozone layer that protects living organisms from harmful ultraviolet radiation, allowing for more diverse and complex life forms to evolve.

Furthermore, the process of photosynthesis involved the consumption of carbon dioxide, which reduced the atmospheric levels of CO2 and led to the deposition of carbon in marine sediments. This contrasted greatly with planets like Venus and Mars, which ended up with atmospheres dominated by carbon dioxide. On Earth, thanks to photosynthetic life, we now have an atmosphere rich in nitrogen and the unique presence of free oxygen.

After 2004, Polish exports increased after the country entered the European Union.

Explanation:

Poland, as multiple other countries of Central and Eastern Europe, has communist past. When the communism fell, Poland struggled for some time, as the country needed to change a lot in its functioning, especially the economy and the development of relations with other countries. Despite the country doing everything right, it was still not able to reach its potential because of the limitations.

This all changed when the country entered the European Union in 2004. The borders opened up, so Poland had access without any limitations with the other countries of the EU, and through it with lot of markets across the world because of the EU's trading agreements. Poland used the opportunity, so its exports increased significantly, and since there was larger market and demand, the Polish companies were producing more as well, skyrocketing the economy.

Answer:

The measurements of two angles are 40 and 140

Explanation:

Let's call the angles as x and y.

We know that supplementary angles must add to 180 degrees,

so,            x+y=180. ---------(i)

Furthermore, we know that x is 75% more than 2 y.

We can write "75% more than" numerically as 1.75,

          so x = 1.75(2 y).

We can simplify the second equation by multiplying

               [tex]1.75 \times 2[/tex]

             x = 3.5 y.

Now we can solve the system of equations by substitution by plugging

3.5y in for x in

         x+y=180.

(3.5 y) + y = 180

Combine like terms.

        4.5 y = 180

              y =[tex]\frac{180}{4.5}[/tex]

              y = 40

Putting the value of y = 40 in equation (i) and calculating the value of x

      x + 40 = 180

             x = 140

The answer is 40 and 140.

Therefore, the measurements of two angles are 40 and 140

Explanation:

the high pressure in the core actually makes the molten rock solid

The thermal energy to melt Earth's inner rock comes from the initial collapse and formation of the planet, as well as from the radioactive decay of unstable elements within the Earth.

The thermal energy to melt Earth's inner rock comes from two sources. Firstly, it comes from the initial collapse and formation of the planet, where gravitational potential energy is converted into thermal energy. Secondly, it comes from the radioactive decay of unstable elements within the Earth, such as uranium, thorium, and potassium. These radioactive decays release energy, which contributes to the Earth's molten interior.

A geographer does not need to be physically present to use remote sensing, which is a method of collecting data from a distance using aerial platforms. This technique is valuable for analyzing the Earth's surface and tracking changes, but it should be complemented by field data for verification.

To address the student's question directly, remote sensing does not require a geographer to be physically present at the location being studied. Instead, remote sensing refers to the technique of acquiring data about the Earth's surface through the use of aerial platforms such as satellites, airplanes, or drones. This allows geographers to collect data and analyze various aspects of an area from a distance.

Remote sensing is particularly valuable because it provides imagery and information about the physical and human characteristics of a place, such as land use and landscape changes, which can be especially useful in inaccessible or vast areas. It leverages the interaction between earth materials and the electromagnetic spectrum, extending our capabilities to see beyond the visible range. For example, analyzing different wavelengths can help identify vegetated areas using the infrared spectrum.

However, it is important to mention that remote sensing serves as a complement rather than a replacement for traditional field studies. For the data obtained to be considered reliable, it often needs verification through field data collection. While remote sensing offers a broad view and can track changes over time, field verification helps ensure accuracy and provides a more detailed analysis at the ground level.

Answer:

5:7

Explanation:

You divide both sides by the same number to find the least common multiple. ex) 10 and 14 are both divisible by 2.

10÷2=5

14÷2=7

Therefore 5m = 7n

Final answer:

Given that 10m = 14n, the ratio of m to n in simplest form is 7:5, after dividing both terms by their greatest common divisor, which is 2.

Explanation:

To find the ratio of m to n in simplest form given that 10m = 14n, we first rewrite the equation in the form of a ratio:

m/n = 14/10

Now we simplify the ratio by dividing both the numerator and the denominator by their greatest common divisor, which is 2:

m/n = 7/5

Therefore, the simplest form of the ratio m:n is 7:5.

Its important to know the source of energy in convection currents because it is what drives the movement of the plates, formation of plate boundaries, and hot spots.

Explanation:

The convection currents are currents that occur in the mantle layer. The prime reason as to why they appear is the difference of heat and pressure between the upper and lower mantle. The energy itself exist because of the core of the Earth, as it is very hot and it has extremely high pressure, so it heavily influences the mantle layer above it.

The importance of understanding the energy source of convection currents is seen in that through it we can understand why we have plate boundaries at some places and not in others, why are spreading zones occurring, and why hot spots occur in the middle of the plates, far away from the boundaries. By understanding these things, we can understand the plate tectonics theory, thus the motion of the plates on Earth's surface.

Warm, moist air in the atmosphere causes an increase in ocean temperatures.  This is one processes that describes the effect Earth's atmosphere has on Earths hydrosphere.

Explanation:

When the atmosphere is warm, this heat is transferred to the oceans by conduction - because the two systems are not isolated from each other they share matter and energy. The warmer the atmosphere the warmer the oceans become. Moist air also means that the atmosphere cannot accommodate as much more moisture. Therefore oceans cannot lose much heat by evaporation. Collectively, warm moist air causes a significant rise in ocean temperatures.

Answer: There are many different types of precipitation —rain, snow, hail, and sleet for example—yet they all have a few things in common. They all come from clouds. They are all forms of water that fall from the sky.

Explanation:

The four main forms of precipitation are rain, snow, sleet, and hail. Each is the result of specific atmospheric conditions and temperature variations.

The four main forms of precipitation are rain, snow, sleet, and hail. Rain occurs when water droplets in clouds become too large and heavy, causing them to fall to the ground. Snow is formed when cold temperatures freeze this water vapor into ice crystals. As for sleet, it happens when raindrops pass through a layer of cold air and freeze before hitting the ground. Finally, hail form in severe thunderstorms when updrafts carry raindrops upward into extremely cold areas of the atmosphere where they freeze and accumulate layers of ice before falling to the ground.

Final answer:

The relationship between a dominant country and its dependency is characterized by an imbalance where the dominant (core) country benefits at the expense of the dependency (periphery), reinforcing patterns established during historical colonial periods that limit the development of the dominated country.

Explanation:

The concept of imperial dynamics explores the relationship between a dominant country and its dependency, which can manifest in various forms including a colony, protectorate, or mandate. This relationship is central to dependency theory, which posits that the global economic system often disadvantages developing regions and countries, creating a dependency on more developed nations. These dependencies often stem from historical colonial trade patterns that normalized the production of low-profit goods in the dominated country, maintaining systems beneficial to the colonizer.

Core countries, with advanced political and economic systems, utilize resources from periphery countries to maintain their status. Dependency theory suggests that the unequal benefits of international trade and economic relations reinforce this imbalance. As a result, the benefits of trade between developed and developing countries often overwhelmingly favor the developed nation.

Additionally, dependency theorizes that industrialized nations influence the fate of developing nations by controlling markets, capital flow, and trade terms, which limits the economic growth and development of the dependent countries. Export industries in developing nations tend to have minimal impact on the rest of the economy, and deficiencies in infrastructure like transportation and financial sectors, as well as human capital, restrict overall economic progress.

Troposphere, stratosphere and mesosphere are the layers of Earth's atmosphere. Their features are as it follows in the explanation bellow.

Explanation:

Troposphere is the lowest layer of atmsphere, and this is the area where all weather phenomenon and life happen. Troposphere goes up to 18 kilometers in height. This is also the densiest layer of atmoshere where almost all water, clouds and air processes exist. Troposhpere is the only one sphere where life is possible.

Stratosphere is the layer between 18-20 km up to 50-55 km in height, above the Earth's surface. This layer is well known for great concentration of ozone (somewhere between 20 and 25 km), and that area is called - ozone layer. Ozone is very important because it absorbs most of the Sun's ultraviolet radiation.

Mesosphere is the layer just above the stratosphere and it spreads between 50-55 km up to 80-90 km. Mesopshere is characterized by significant temperature drop (lower parts has around 0 degrees and uppermost parts are very cold, at -90 degrees Celsius). Upper segments of mesopshere is known as ionosphere. That is the layer with charged iones, and it is well known for formation of polar light (aurora)
