FAQs on Composition of Atmosphere - Indian Geography, UPSC IAS Exam Preparation Video Lecture - Geography (Prelims) by Valor Academy
| 1. What is the composition of the Earth's atmosphere? |  |
Ans. The Earth's atmosphere is primarily composed of nitrogen (78%), oxygen (21%), and traces of other gases such as argon, carbon dioxide, neon, helium, and methane.
| 2. How does the composition of the Earth's atmosphere affect the climate? | |
Ans. The composition of the Earth's atmosphere plays a crucial role in determining the climate. The greenhouse gases present in the atmosphere, such as carbon dioxide and methane, trap heat from the sun and contribute to the greenhouse effect, leading to global warming and climate change.
| 3. What are the main functions of the Earth's atmosphere? | |
Ans. The Earth's atmosphere has several important functions, including providing oxygen for respiration, protecting the Earth's surface from harmful solar radiation, regulating the temperature through the greenhouse effect, and distributing heat and moisture around the planet through atmospheric circulation.
| 4. How does air pollution impact the composition of the Earth's atmosphere? | |
Ans. Air pollution, caused by human activities such as burning fossil fuels and industrial emissions, can significantly impact the composition of the Earth's atmosphere. It increases the concentration of pollutants, such as sulfur dioxide and nitrogen oxides, which can lead to the formation of smog and acid rain. This pollution can also contribute to the depletion of the ozone layer and the increase in greenhouse gases, further exacerbating climate change.
| 5. How does the composition of the Earth's atmosphere vary with altitude? | |
Ans. The composition of the Earth's atmosphere varies with altitude. As altitude increases, the density of the atmosphere decreases, and the concentration of gases also decreases. For example, the concentration of oxygen and nitrogen decreases at higher altitudes, while the concentration of other gases, such as helium and hydrogen, becomes more significant. Additionally, the upper layers of the atmosphere, known as the exosphere, contain a very low concentration of gases and are predominantly composed of hydrogen and helium.
