Question

How do convection currents occur in liquid?

Answer 1

The particles in these fluids can move from place to place. 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. ... This is because the particles in liquids and gases move faster when they are heated than they do when they are cold.

Hope it helps :)
