Question

How does the greenhouse effect make the Earth hospitable?

Answer 1

GREENHOUSE EFFECT:

1. Greenhouse gases play a vital role in maintaining a suitable temperature for our planet Earth.
2. In the absence of this effect, all the heat given out by the Earth would simply emit from the surface into space.

Hence, the greenhouse effect makes the Earth hospitable because, without it, an average temperature of about -20°C will exist on Earth which will make life impossible.
