Sedimentary Rocks
Sedimentary rocks form when small pieces of sediment settle here
What is at the bottom of rivers and oceans
When heat and this deep inside the earth cause igneous and sedimentary rocks to change, metamorphic rocks are formed.
What is pressure
The scale we use to measure the hardness of minerals
What is the Mohs scale
After a volcanic eruption the magma eventually does this
What is cools and hardens
Sediment is created when wind and this break water into small pieces
What is water
The word metamorphic means this
What is to change form
The numbers included in the Moh's scale
What are 1-10
A rock that is formed when sediment hardens at the bottom of rivers and oceans.
What is sedimentary
The type of rock that is formed after magma or lava cools and hardens
What is igneous rock
Sediment can include small pieces of plants, organic matter, and this
what is minerals
Texture differences in metamorphic rocks divides them into this many main groups.
What is 2
How a mineral reflects light. Glassy, pearly, metallic, non-metallic are examples
What is lustre
A rock that forms when heat and pressure deep inside the Earth cause igneous and sedimentary rocks to change.
What is metamorphic
After an igneous rock has experienced weathering it becomes this (not a type of rock....yet)
What is sediment
Some sedimentary rocks have this because these rocks form at temperatures and pressures that don't destroy them
What are fossils
A type of metamorphic rock that has visible layers of minerals
What is a foliated rock
A diamond would be this number on the Mohs scale
What is 10
A type of igneous rocks that forms at the Earth's surface
What is extrusive igneous rock
Once sediment cements it becomes this type of rock
What is sedimentary rock
Sedimentary rocks usually have this because of the way the sediment was deposited
What are layers
A type of metamorphic rock that does not have distinct layers
What is non-foliated rock
Talc would be this number on the Mohs scale
What is 1
A type of igneous rock that forms inside the Earth's surface
What is intrusive igneous rock
Once a metamorphic rocks melts it turns into this
What is magma
