Define a greenhouse gas.

Geography
1 answer:
Art [367]3 years ago
8 0

Answer:

The correct answer is A. Greenhouse gases allow visible light to pass through and warm the Earth's surface, and prevent heat energy from radiating back out into space.

Explanation:

The greenhouse effect of the gases is due to the fact that they transmit sunlight at a higher frequency than infrared, which heats up soil, trees and water. That heat cannot then radiate into space again like infrared radiation because the greenhouse gases partially absorb it. The effect is that the Earth's temperature rises until a completely new equilibrium temperature is reached.  The most significant greenhouse gases are water vapor, carbon dioxide, methane, and tropospheric ozone.

The concentration of greenhouse gases in the atmosphere is constantly increasing at an accelerating rate due to human activities. The annual growth rate is currently two millionths of a year.

Description of water pollution
umka21 [38]
Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). This form of environmental degradation occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds.

Water pollution affects the entire biosphere – plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and population, but also to the natural biological communities.
