Question

4 where can convection currents occur? choose three. in an ocean in ice in air in a vacuum in liquified rock

Explanation:

Convection currents require a fluid (liquid or gas) medium as they involve the movement of matter due to density differences from heat. Oceans (liquid water), air (gas), and liquified rock (magma, liquid) can have convection. Ice is solid (no fluid movement), and a vacuum has no matter, so no convection.

Answer:

A. In an ocean, C. In air, E. In liquified rock
