i just took the quiz and it showed this as the correct answer. hope this helps

Answer 2

What happen in convection current can be described as

A: Cold, dense material sinks while hot, less dense material rises.

• A convection cell can be regarded as system in which a fluid is loses its density by becoming warmed, then then will now be forced to move to region of greater density

• Convection cells in Earth's atmosphere is the cell that helps in the blowing of wind as well as some other natural and manmade phenomena.

Some types of global convection cells that exists are:

1. Hadley Cell
2. Polar Cells.
3. Ferrel Cells

• For the formation of convection cells to occur there must be intense heat from the core which cones from circulation of fluid from magma.

Therefore, option A is correct.
