Sedimentary Rocks

"Sedimentary rocks are formed by the deposition and cementation of that material at the Earth's surface and in bodies of water"

Three main types of sedimentary rocks include; Clastic, Chemical, and Organic

clastic
chemical
organic
Sedimentary rocks are typically found when sand, mud, and pebbles get laid down in layers. Eventually, these layers are squished under more layers.
sedimentary rocks occur through weathering and cementing

Metamorphic Rocks

"A metamorphic rock is when a rock has been altered by extreme heat and pressure."

Two types of metamorphic rocks include: Foliated and Non-Foliated

foliated
non-foliated
They can be found deep inside the Earth through pressure and heating by magma.
metamorphic rock occur with melting and breaking down
