Answer 1

Question:

Green house gases are useful for living organisms. Why? Give reasons.

Answer:

Greenhouse gases keep our planet livable by holding onto some of Earth's heat energy so that it doesn't all escape into space. This heat trapping is known as the greenhouse effect. Just as too little greenhouse gas makes Earth too cold, too much greenhouse gas makes Earth too warm.

The greenhouse gases help block the harmful solar radiation from reaching planet's surface. These gases work like a filter and bounce back most of the unwanted and damaging energy into space. Ozone, which is one of the crucial greenhouse gases, absorbs the harmful ultra-violet (UV) rays of the sun.

Answer 2

Explanation:

Greenhouse gases keep our planet livable by holding onto some of Earth's heat energy so that it doesn't all escape into space. This heat trapping is known as the greenhouse effect. Just as too little greenhouse gas makes Earth too cold, too much greenhouse gas makes Earth too warm.

Besides CO2 there are other greenhouse gases. These include water vapor, methane, nitrous oxide, and ozone. Without any greenhouse gases, Earth would be an icy wasteland. Greenhouse gases keep our planet livable by holding onto some of Earth’s heat energy so that it doesn’t all escape into space. This heat trapping is known as the greenhouse effect.
