Answer 2

Answer:

• Answer: Earth's atmosphere is a mixture of nitrogen (79%), oxygen (20%), and a small fraction of carbon dioxide, water vapours and other gases. However, the atmospheres on Venus and Mars mainly consist of carbon dioxide. ...
• The atmosphere is an envelope of gases that surround the Earth or any other plant. This layer of gases acts as a protective blanket as it is a thin layer around the earth. The atmospheric layer is held in its position due to the gravitational force on the earth.
• The atmosphere protects the entities on earth from the Sun which produces harmful radiations and also the scorching heat.
• It comprises tons of gases, water vapour and dust particles.
• Any fluctuation in the atmosphere will have an impact on the climate and weather conditions.
• Thus, the atmosphere is critical in preventing a sudden rise in the temperature during the daytime and in the nighttime, it reduces the rate of heat that escapes into the outer space.
• Along the cold front, the denser, cold air pushes up the warm air, causing the air pressure to decrease. If the humidity is high enough, some types of cumulus clouds will grow. High in the atmosphere, winds blow ice crystals from the tops of these clouds to create cirrostratus and cirrus clouds.
• The following three human activities would lead to air pollution: (i) Burning of fossil fuels like coal and petroleum. (ii) Emission of harmful gases and dust particles from vehicles . (iii) Smoke released from industries containing harmful gases like sulphur dioxide, oxides of nitrogen.
