What type of rock does limestone turn into? It is often used on countertops.
Marble
Give an example of an extrusive igneous rock.
Pumice, Basalt, Obsidian
When a metamorphic rock is turned into an igneous rock, what processes are happening? (2)
Melting and cooling/hardening
Why do intrusive rocks have large crystals and grains?
Because the magma cools slowly underground
