Because there are 2 types of igneous rocks:- •Intrusive rocks-are rocks when the magma cool’s down before reaching the surface of the earth. •Extrusive rocks-are rocks when magma cools down after reaching the earths surface. So their composition can be different because of the formation of the rocks at different places. Eg:-Granite rock:-intrusive rock. Basalt:-extrusive rock
Storms could be produced in the future as the hot air moving across the water could carry the water vapor high into the atmosphere. Humidity would also be lower than expected if the hot front wasn’t right along the water.
Superposition is the geologic principle which explains why the bottom stratum in a section of rock is the oldest. The word literally means placing one thing on top of another where the lower strata are the older.
