The name of a person that studies rocks.
What is a geologist.
The way rocks are classified.
What is how they were formed.
The way that different types of rocks are formed.
Igneous: By the cooling of magma/lava
Metamorphic: By applying force and heat to rocks under the surface of the earth.
Sedimentary: Many different rocks cementing together to form layers.
When a mineral is not scratched by corundum, it's hardness is this number.
What is 10.
