What is the composition of the Earth’s atmosphere?
The Earth’s atmosphere is primarily composed of nitrogen (78%), oxygen (21%), argon (0.9%), and carbon dioxide (0.04%), along with trace amounts of other gases and water vapor.
What are the different layers of the atmosphere?
The primary layers of the atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, each with distinct characteristics and functions.
What is the greenhouse effect, and how does it impact the Earth’s climate?
The greenhouse effect is a natural process where certain gases in the atmosphere trap heat from the Sun, maintaining the Earth’s suitable temperature for life. However, excessive greenhouse gas emissions can lead to global warming.
What causes air pollution, and what are its effects?Â
Air pollution is primarily caused by human activities like burning fossil fuels, industrial processes, and vehicle emissions. It can have adverse effects on human health, the environment, and contribute to climate change.
What is atmospheric circulation, and how does it influence weather patterns?
Atmospheric circulation refers to the movement of air masses across the Earth’s surface, driven by differences in temperature and pressure. This circulation plays a crucial role in determining weather patterns and distributing heat and moisture globally.
