Answer 2

The answers to the following 5 questions and their explanations are as follows:

• 6.(Option d) All of these Human activities Cause global warming. Due to various human activities each and every day, the temperature of the earth's atmosphere is increasing. That's called Global Warming. Causes are Cfc gases, industrial activity, deforestation,Selfishness of humans etc.
• 7.(Option a)Radiative forcing is causing global warming. This is nothing but the change of energy flux in our surrounding atmosphere caused by natural or man-made activities.
• 8. Human activity is one of the main reasons for global warming. This has influenced GW (Option c) By changing the radiative balance governing the Earth.
• 9. From the following, the global radiative forcing of our climate is (Option a)Aerosols. Aerosols are basically a suspension of very little solid particles or droplets that are usually mixed with other gas or air. Example- Smoke.
• 10. The one land use which causes global warming is (Option b.)Surface reflectance. The more times rays reflect on the surface the more global warming gains.
