Earth's Atmosphere Composition. Some people are surprised to learn that oxygen isn't the most abundant gas in Earth's atmosphere composition. Based on the relative volumes of the gases in Earth's atmosphere, nitrogen is actually more than 3 times more than oxygen.

Carbon in Earth's Crust

The Earth's crust is composed of various minerals and rocks, and carbon is one of the most abundant elements found within it. However, the percentage of carbon in the Earth's crust is relatively low compared to other elements.

Carbon Content
- Carbon makes up only about 0.02% of the Earth's crust by weight.
- This low percentage is because most of the carbon on Earth is present in other forms such as carbon dioxide in the atmosphere, dissolved carbonates in water bodies, and organic matter in the biosphere.

Presence in Minerals
- Carbon is found in different minerals in the Earth's crust, such as carbonates and organic compounds.
- Carbonates, which are compounds containing carbon and oxygen, are widespread minerals and play a crucial role in the carbon cycle.
- Examples of carbonates include limestone (calcium carbonate), dolomite, and siderite.

Carbon in the Atmosphere

Carbon is also present in the Earth's atmosphere, primarily in the form of carbon dioxide (CO2).

Carbon Dioxide Concentration
- Currently, carbon dioxide constitutes approximately 0.04% of the Earth's atmosphere by volume.
- This concentration has been increasing due to human activities such as the burning of fossil fuels and deforestation, leading to concerns about climate change and global warming.

Carbon Cycle
- The carbon cycle is the process by which carbon is exchanged among the Earth's atmosphere, oceans, biosphere, and geosphere.
- It involves various natural processes such as photosynthesis, respiration, and the weathering of rocks.

Role in Climate Change
- The accumulation of carbon dioxide in the atmosphere, primarily from human activities, has led to an enhanced greenhouse effect, trapping more heat and causing global temperatures to rise.
- This phenomenon is commonly referred to as anthropogenic climate change.

In conclusion, carbon is a crucial element present in both the Earth's crust and atmosphere. While the percentage of carbon in the crust is relatively low at 0.02%, carbon dioxide in the atmosphere constitutes around 0.04%. Understanding the distribution and cycling of carbon is essential for comprehending Earth's climate system and the impact of human activities on the environment.

Read the following text and answer the following questions on the basis of the same:Ozone layer depletion:We are all exposed to UV radiation from the sun. The sun is by far the strongest source of ultraviolet radiation. UV radiation spectrum is divided into three regions called UVA, UVB and UVC. As sunlight passes through the atmosphere, all UVC and most UVB is absorbed by ozone, water vapour, oxygen and carbon dioxide. UVA is not filtered as significantly by the atmosphere.The three types of UV radiation are classified according to their wavelength. They differ in their biological activity and the extent to which they can penetrate the skin. The shorter the wavelength, the more harmful the UV radiation. The UV region covers the wavelength• UVA (315-400 nm)• UVB (280-315 nm)• UVC (100-280 nm).Short-wavelength UVC is the most damaging type of UV radiation. However, it is completely filtered by the atmosphere and does not reach the earth's surface.UV level reaching the earth changes with latitude and altitude.UV levels are higher closer to the equator. Closer to the equator the sun's rays have a shorter distance to travel through the atmosphere and therefore harmful UV radiation absorption is less.With increasing altitude less atmosphere is available to absorb UV radiation. With every 1000 m in altitude, UV levels increase by approximately 10%.Ozone is a particularly effective absorber of UV radiation. As the ozone layer gets thinner, the protective filter activity is progressively reduced. Consequently, the people and the environment are exposed to higher levels of UV radiation, especially UVB.Ozone depletion is caused by human-made chemicals released into the atmosphere.Q.
