Question

Which statement correctly describes convective lifting?

Unequal heating of Earth's surface from below ground causes pockets of air to be warmed more than the surrounding air, causing the parcels to rise.

Equal heating of Earth's surface from below ground causes a layer of air to be warmed, causing this layer to rise.

Unequal solar heating of Earth's surface causes pockets of air to be warmed more than the surrounding air, causing the parcels to rise.

Equal solar heating of Earth's surface causes a layer of air to be warmed, causing this layer to rise.

Hint***Equal heating of Earth's surface would not affect distinct pockets of air.

Answer 1

Unequal heating of Earth surface from below ground causes pockets of air to be warmed more than, surrounding causing the air to rise.

This is the process of Convection. Other options are incorrect, because equal heating in two options will cause no difference, hence no reason for air to rise. Third option is not correct because air is not heated directly by solar heating, the ground absorbs the radiation and then it's heats overlying air.
