Answer 2

As we all know that the temperature of earth remain constant.

It is because of atmosphere.

But in plantes such as Mercury, Venus and Mars there is no temperature.

And these are also made up of rocks like earth.

So , this is why they are very hot during the day and very cold at night.

And mercury is very close to sun also.

So in the day time temperature rises very high .

While at night the temperature goes very low .
