What is the greenhouse effect?

The degrees of latitude have different angles of heating.
List the three main climate zones from coldest to warmest.
Polar zone, temperate zone, tropical zone
What force drives winds and ocean currents?
The unequal heating of Earth.
What is the process in which water rises toward the surface in warmer regions called?
Upwelling
