Where do convection currents occur? O A. In areas with different air pressures
O B. In areas with the same temperature
O C. In areas with different cloud types
O D. In areas with the same altitude

the answer is A-in areas with different air pressures

Explanation:

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
