its the driving mechanical movemet!
earthquakes and volcanoes
Plates on the Earth's mantle are carried around by convection currents from the magma. This happens incredibly slowly.
it becomes a liquid

The flow of mantle effects convection currents in the mantle. This process happens as hot material within the mantle begins to rise. As it rises, it begins to cool and then sinks. This process repeats as a cycle of convection currents.
it makes more magma.
It happens in the mantle and crust because the focus is the starting point and it is usually starts at the lithosphere(mantle) or near the mantle, but almost there.The focus rises up and the epicenter is the start of the earthquake.
it means someone has mantle problem
Because its closer to the mantle and the core.
the minerals posses a number of properties that are used as an aid in their identitification
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.
