|
change direction.
|
|
|
eventually stop.
|
|
|
continue at the same rate forever.

Explanation:
Detailed explanation-1: -Convection currents continue as long as heat is added. What happens after the heat source is removed? Without heat, the convection currents will eventually stop when all of the material has reached the same temperature.
Detailed explanation-2: -How does convection work? Convection works by areas of a liquid or gas heating or cooling greater than their surroundings, causing differences in temperature. These temperature differences then cause the areas to move as the hotter, less dense areas rise, and the cooler, more dense areas sink.
