Polar climates are found near what?

• The Equator

• The Poles

• The Ocean

• The Forest

Answer explanation

Polar climates are characterized by extremely cold temperatures and are primarily found near the Poles, specifically in regions like Antarctica and the Arctic, rather than at the Equator, the Ocean, or the Forest.
