Rock Cycle
(Imagine this as a deep narrater voice in every documentary)
Magma
When rocks melt in the certain of the Earth, it is called magma. As tectonic plate moves, magma finds a way out and cools for its transformation to a rock. The newly formed rock is called an igneous rocks.
Igneous Rocks
After magma cools, it becomes an igneous rocks it has 3 options, it could weather and erode to an sediment, melt back to magma, or go under heat and pressure to turn into a metamorphic rock
Examples of igneous rocks
Sediments and Sedimentry
Sediments happens when rocks erode and weather away. Under pressure, sediments come together and become a singular rocks, called a sedimentary rock. The main feature of many sedimentary rock is it is layered or looks like it is made from little rocks. Sedimentary rocks will usually either melt down to magma, erode and weather away, or heat up and put under pressure to become a metamorphic rock.
Metamorphic Rocks
Metamorphic occurs when a rock goes underground and is exposed to high pressure and heat. This mostly changes the rock structure and texture of the rock. There are two types of metamorphic rocks, foliated and non-foliated rocks. Foliated rocks have bands or striped on it due to exposure to heat and pressure, while non-foliated rocks isn't banded or striped
