Igneous Rocks
This cools and hardens to form igneous rock.
magma or lava
These types of rocks were originally sedimentary or igneous rocks.
Metamorphic rocks
The 'shininess' or dullness of a mineral.
Lustre
Name the three types of rock groups.
Sedimentary, Igneous and Metamorphic
This is the center of the earth.
Inner core
This is the layer of the Earth where magma forms igneous rocks.
The mantle
The type of rock that can contain fossils.
Sedimentary
The scale that is used to measure the hardness of minerals
Moh's Hardness Scale
A hard substance composed of one or more minerals.
Rock
The thinnest layer of the geosphere.
The crust
This kind of igneous rock is formed below the earth's surface when magma cools.
Intrusive igneous rock
These 2 things cause metamorphic rocks to form.
Heat and pressure
You can see this property just by looking at a mineral. Some minerals have many.
Color
When crystals break into different parts with an uneven surface.
Fracture
The layer of the Earth that is liquid.
The outer core
Name 1 example of an igneous rock.
Granite, basalt, or pumice
Where sedimentary rocks are formed.
Bottom of lakes, seas, or oceans
The hardest mineral.
Diamond
Name one way people use rocks.
Buildings, walls, roads, roofs
Magma is found here.
The mantle
This igneous rock is made up of quartz, feldspar, and mica.
Granite
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
Sediments
4 ways to test the properties of a mineral.
Lustre, hardness, color and cleavage or fracture
Name the rock we use in the roofs of houses.
Slate
This is made up of the mantle and the crust.
The lithosphere
