give me the introduction of heating of the atmosphere
Answers
Answer:
Due to the chemical composition of the earth's atmosphere, most of the infrared radiation emitted by the warm surface never reaches space. Instead, the radiation is reflected or absorbed by compounds known as greenhouse gasses. When these compounds absorb the infrared radiation from the surface, the atmosphere heats up. The energy reflected back toward the earth warms the surface further, causing the earth to emit more infrared radiation. This creates a cycle that keeps the atmosphere and the surface warm.
- BUT IF IT EXCEEDS LIMITS EARTH WILL BECOME HOTTER AND HOTTER AND THE FIRST CONSEQUENCE INCURRED IS THE MELTING OF GLACIERS...WHICH CAUSES FLOODS, OVERFLOW OF SEA WATER, ETC!
→ Once solar radiation reaches the earth's surface, the ground and bodies of water absorbs nearly all of it. Only about 4 percent is reflected back into space. By absorbing solar energy, these surfaces heat up. Warm objects begin to radiate long-wave infrared radiation. Without the atmosphere, this energy would radiate out into space.
