Theory of PLATE TECTONICS
... • The crustal (lithospheric) plates typically contain oceanic and continental crust. • As the plates move, they can separate, collide, or slide past one another. • This results in three kinds of plate boundaries animations 1. Divergent -apart 2. Convergent-together 3. Transform-slide side by side • ...

Metamorphism

The deeper a rock is beneath the surface, the hotter it will be. The particular temperature for rock at a given depth depends on the local geothermal gradient. A mi ...

Why do volcanoes erupt?
... Magma is a mixture of molten or semi-molten rock, solid rock and gases formed from the partial melting of the crust and/or mantle. Most of the world’s 550 active volcanoes on Earth are located along the margins of adjacent plates. When two plates collide at a destructive plate boundary, subduction w ...
