Answer:

1.) D

2.) The density of the material is greater at A because it is away from the core. As a material goes away from the core it's density decreases.

3.) The heat that drives the convection current in the mantle comes from the core of the earth.

4.) As the material moves from point D towards point B the temperature decreases. As the temperature decreases the density increases. Gravity takes a stronger effect on the material and it begins to fall back towards the core at point B.

5.) As they rise, gas molecules in the magma come out of solution and form bubbles and as the bubbles rise they expand. Eventually the pressure from these bubbles is stronger than the surrounding solid rock and this surrounding rock fractures, allowing the magma to get to the surface.
