Explanation:

Compacting and cementing forms sedimentary rocks from sediments. Cooling can form igneous rocks from magma or lava. Heat and pressure create metamorphic rocks. Melting changes rocks into magma. Without seeing the animation, we can't be certain, but these are the main geologic - rock - forming processes.
