All fluids move from areas of high pressure to areas of low pressure. The same happen for magmas which are fluids of higher viscosity. Now magmas can also move because of differences in density, low density fluids will move upward, high density fluids move downward. The interplay of this two processes explain how magma moves in earth's crust.

Magma rises in the Earth's crust as a result of plate tectonics. Plate Tectonics is responsible for volcanoes, earthquakes, and any type of rock folding.

It's hot heat rises - the moon did it - centrifugal force - oh ya what the other guy said
