What is the rock cycle?
The continuous series of changes a rock undergoes.
200
In the rock cycle, what does an existing rock turn into a how?
A metamorphic rock because of heat, pressure, or chemicals
300
What is the hardest mineral?
Diamond
300
What are the 2 types of luster?
Metallic and nonmetallic
300
In the rock cycle, what does a molten rock turn into? How?
Turns into an igneous rock because it cools and hardens
300
What the cleavage of a mineral?
The tendency to split a mineral along a flat surface.
300
In the rock cycle, what does sand, soil, remains of an organism turn into? How?
Sedimentary rock because it is pressed together and hardens.
400
What are 4 out of 5 properties of a mineral?
Luster, streak, color, hardness, and cleavage
400
Does a metallic mineral have a shiny or dull luster?
Shiny
400
Where might you find an igneous rock?Why?
At the base of an active volcano because igneous rocks are formed when molten rock from a volcano cools and hardens.

What the difference between a rock and a mineral?
A rock is made up of minerals.
A mineral is nonliving solid material found in the Earth's crust and is made up of definite chemicals.

Outer core: liquid core
Mantle: thick layer of rock between the crust and core
Crust: layer under the ocean

What is the difference between testing a mineral's hardness and streak?
Hardness: how easily a mineral can be scratched.
Streak: color when it is grounded to powder.

In a rock cycle, what must occur for igneous rock to become sedimentary rock?
Igneous rock must be weathered into sediment. Then, the sediment must be cemented together.
