What parts of earth does the sun warms?

Answer 1

The sun warms the whole Earth, more in some places like the equatorial areas; less in some places like the polar areas.

Answer 2

The sun warms the Earth's surface, atmosphere, and oceans. The sunlight is absorbed by the Earth's surface, causing it to heat up and then radiate heat back into the atmosphere. The atmosphere traps some of this heat, leading to the warming of the planet.
