The volcano
A volcano.
Plate movements may also create cracks in the crust.
Molten magma below the plates
forces its way up through the
cracks When the magma
rushes out violently, an explosive
volcano eruption occurs After
a series of eruption, a mountain if
built up. This is called
a volcano.
Volcanoes are cone-shaped and have a broad base. At the top of a volcano,
there is a creater.
Sometimes, magma just runs out through the cracks and reaches the surface
as lava
flow.
The flow usually covers
a large area.
