Igneous
How are rocks classified
Rocks are classified by how they are formed.
What does metamorphic mean
Metamorphic means to change
what happens when igneous rocks melt
It turns to magma
What happens when metamorphic rock goes through weathering & lithification
It turns to sediments
How are Igneous rocks formed
Igneous rocks form when magma or lava cools and hardens
How are metamorphic rocks created
The Earth squeezes and heats existing rocks and therefore changes their appearance
what happens when Igneous rocks meats heat and pressure
It turns into metamorphic rock
What happens when new rocks are formed
Old rocks are weathered away
Where are intrusive igneous rocks formed
Intrusive igneous rocks are formed below Earth’s surface
What are sediments
Sediments are material that is carried by water, wind, glaciers, and gravity
With weather and lithification what happens to metamorphic rock
It becomes sediments
What are the 4 ways minerals are made
1.Cooling of magma
2.Cooling of lava
3.Evaporation of a solution in which the dissolved minerals are left behind
4.Precipitation of solids from a solution
What is Organic Material
Organic material is things that are living or were once living
How are Sedimentary rocks formed
These rocks are formed layer by layer of other rocks, minerals or plants and animals
With weathering and lithification what happens to igneous rocks
It turns into sediments
How are diamonds created
magma
True or False: Intrusive igneous rocks had time to cool slowly and therefore contain crystals and large mineral grain
True
Where is the oldest sedimentary rock layer found
It is found at the bottom
With compaction & cementation what happened to sediments
It turns into sedimentary rock
What do gems cool into
kimberlite
