Rock Creation
Metamorphic
A sedimentary rock effected by magma
Heat and pressure change the shape and chemical compound of rock
Types of metamorphism
Regional
Magma from the surrounding area heat up the rock without touching it changing the rock
Contact
When the magma directly touches the rock changing it
Igneous
Convection currents bring the magma to the surface
You can find the magma at volcanoes, divergent plate boundaries, volcanic hot spots, vents or fissures
Volcanic islands also experience earthquakes due the the pressure of the rising magma
Created by molten magma
Sedimentary
Rocks break down
Sediments of the broken down rock are moved
The sediment piles up crating layers
Pressure makes the sediments turn into a rock
Formation of the Earth
200 Million Years ago
Tethys Sea
The body of water surrounding Pangaea
Pangaea
Super continent consisting of all 7 current continents
Continental Drift
Pangaea was broken into two smaller continents
