What is unique about the materials convection takes place in?

it is cool


Why does cool rock materials sink when convection takes place in the mantle?

Cool things always sink (because they are more dense) and hot things always rise (because they are less dense) in convection. It does not matter if it is rock, air, water, metal, wax, oil, etc., convection always works the same.


When convection takes place in the matle why does cooler material sink while warmer material rises?

Cooler material (magma) shrinks and becomes more dense. Gravity acts on this denser material more strongly because of its greater unit mass (density = Mass/volume). Lighter material rises as the heavier material displaces it below. This produces a the apparent bouyant force.


What takes place when one plate is forced down into the mantle beneath another plate?

Subduction! :)


When convection takes place in the mantle why does rock material sink and warm rock material rise?

This happens with all liquids which have varied heat through out it, in fact even in the air. This happens because when objects get hotter, they vibrate more, and thus take up more space. This means that the same mass takes up more space, meaning that the substance becomes less dense. Therefore, the hotter rock rises above the cooler rock because it vibrates more, so takes up less space, so is less dense. From there, denser substances fall to the bottom because the heavier objects can push the lighter substances out of the way, which in this case, is upwards.

No


Why is solar energy transferred to earth by radiation not convection?

Convection takes place through a material medium between source and sink. There isn't any material medium between sun and earth, and we are therefore thankful that radiation exists.


How do convection currents work in the mantle?

What forces would lead to the movement of the plates over the surface of the earth? At this time it is believed this movement results from mantle convection. Deep within the earth there is a large amount of heat coming from two sources: the magma remnants of the Great Bombardment, and radiation from radioactive elements. This heat, in accordance with the 2 ndlaw of thermodynamics, must flow to a cooler place, and subsequently rises to the surface of the Earth. If the Earth were smaller, this heat would flow by conduction, but because of the relatively large size of the Earth, convection also takes place. Thus, as in heating a pot of water on a stove, convection currents are established within the earth, which bring warm material to the surface and send cooler material to the interior.
