FAQs on Carbon Cycle and Water Cycle Video Lecture - Crash Course for BMAT

1. What is the carbon cycle?

Ans. The carbon cycle refers to the process by which carbon is exchanged between the atmosphere, oceans, and living organisms. It involves various stages such as photosynthesis, respiration, decomposition, and combustion, and plays a crucial role in maintaining the Earth's carbon balance.

2. What is the water cycle?

Ans. The water cycle, also known as the hydrological cycle, is the continuous movement of water on, above, and below the Earth's surface. It involves processes like evaporation, condensation, precipitation, and transpiration, and is essential for the circulation of water and the replenishment of freshwater resources.

3. How does the carbon cycle affect climate change?

Ans. The carbon cycle is closely linked to climate change. Increased levels of carbon dioxide in the atmosphere, primarily caused by human activities such as burning fossil fuels, lead to the greenhouse effect. This results in the trapping of heat, leading to global warming and subsequent climate change.

4. What are the main sources and sinks of carbon in the carbon cycle?

Ans. The main sources of carbon in the carbon cycle include the burning of fossil fuels, deforestation, and volcanic activity. The main sinks, or reservoirs, of carbon are the atmosphere, oceans, and land. Plants and trees also act as important sinks through the process of photosynthesis.

5. How does the water cycle contribute to the Earth's climate regulation?

Ans. The water cycle plays a crucial role in regulating the Earth's climate. Through processes like evaporation and transpiration, water absorbs heat energy from the sun, cooling the Earth's surface and maintaining a stable temperature. Additionally, water vapor in the atmosphere acts as a greenhouse gas, helping to regulate the overall greenhouse effect and temperature balance.
