THE ROCK CYCLE!!!!!!!!
The Rock Cycle, to be exact, goes something like this: when the Magma comes out of the volcano it becomes Lava. When the Lava cools it becomes Igneous Rock and it is extrusive form. Next, Mechanical Weathering starts, which is rain that washes sediment of the rock. The sediment will go into an ocean or a lake and it will compact together, because of lithifocation, and form a Metamorphic Rock. Then the Metamorphic Rock will have all it's layers that are named "The Strata" (or they can be called the beds) and the Metamorphic Rock will go through a phase which is either foliated or nonfoliated. After this phase the Metamorphic Rock will turn into Magma.
