convection within the earth is important in driving plate tectonics b) convection within the earth is correlated to processes that occur on its surface. c) convection within the earth transfers mass and heat. d) convection within the earth occurs in response to a decrease in density due to heating.

The widely recognized scientific hypothesis known as plate tectonics states that the Earth's lithosphere is made up of many major tectonic plates that have been gently moving since around 3.4 billion years ago.

Why is convection important to plate tectonics?

Geologists believe that convection currents in the earth's mantle are responsible for the movement of tectonic plates. The rising, spreading, and sinking of gas, liquid, or molten material brought on by the application of heat is referred to as convection currents.

Define motion of the plates.

Four broad patterns can be used to explain the motion of plates:

collision: the coming together of two continental plates
Spreading: when two plates are forced apart from one another
When two plates glide past one another, this is known as transform faulting.
subduction: whenever one plate slides under another.
