Metamorphic Rocks
Read previous Article :Difference between Chemical and Biogenic Sedimentary rock
Memorphic rocks are rocks that have been "changed". They form when igneous or sedimentary rocks are heated, crushed, or deeply buried.
They are often harder than the original rock.
Volcanic Heat
As lava forces its way through the earth's crust, it heats and crushes the rocks nearby. The heat and the pressure change
the whole make up of the rock.
Tectonic Plates
The earth's crust is broken into sections called tectonic plates. These move very slowly, carried by the rock beneath them.
When tectonic plates move towards each other, they squash layers of rock.
Meteorite Crater
When meteorites hit the earth, they melt or shatter the rock where they land.
