Question

C. Give reasons.
1. Carbon dioxide regulates the temperature of the lower atmosphere.
2. The percentage of water vapour in the atmosphere varies from season to season.​

Answer 1

Answer:

1.According to the theory, carbon dioxide controls temperature because the carbon dioxide molecules in the air absorb infrared radiation. The carbon dioxide and other gases in the atmosphere are virtually transparent to the visible radiation that delivers the sun's energy to the earth.

2.Water vapour enters the atmosphere primarily by the evaporation of water from the Earth's surface, both land and sea. The water-vapour content of theatmosphere varies from place to place and from time to time because the humidity capacity of air is determined by temperature.
