Hi there! I`m Nacy and I want tell you all about the rock cycle!

There´s a rock cycle? I thought only water had a cycle!

Yes! It is due to natural cause such as heat, cooling, and erosion.

But right now, you are sedimentary rock

Yes! That means I am formed near Earth´s surface by the buildup of pieces of preexisting rocks or by other

Sorry!

But if you add heat and pressure, I turn into a metamorphic rocks make up large part of Earth´s crust

I changed shape without going through a liquid phase. I am now a metamorphic rock.

Metamorphic comes from the word metamorphism , meaning change in form.

when metamorphic rock gets very hot from the earth´s core, it becomes magma.

Sometimes magma contains crystal and dissolved gas.

Magma is a mixture of rocks and solid beneath the earth´s crust

When magma cools, it becomes a solid and then it turns to an igneous rock
