minerals
A mineral is either made of an......
element or a compound
mineral
a naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition
igneous rocks can come from either
magma or lava
Rock formed from compacted sediment.
Sedimentary rock
How are metamorphic rocks formed
by heat and pressure
A mineral is (4 things)
1. Naturally occurring
2. Inorganic Solid.

2. Organic
3. Chemical
What are the two types of textures that are Metamorphic rocks
Foliated and Non-Foliated
crystals can form from
magma or soulution
Luster
The way a mineral reflects light
Name a common rock that is an igneous rock
Bassalt, granite, obsidian
What is weathering
The breakdown of rocks into smaller pieces
Rocks that are formed when heat and pressure turn old rocks into new rocks.
Metamorphic rocks
Magma cooled quickly
we get large,regular cyrstals
fracute
A minerals to split easily along flat surfaces
What are some qualities for a magma igneous rock
High level of silica
lighter color
Felsic
True or False?
Fossils are only found in sedimentary rocks
True
Give three examples of foliated metamorphic rocks and explain how they form.
slate, phyllite, and gneiss.
Magma cooled quickly
we get small, irregular cyrtsals
Density
the amount of mass in a given volume
What are some qualities of igneous lava rocks
low level of silica
darker colored
mafic
