Igneous Rocks
This can cool and harden and form igneous rock.
What is magma or lava?
PAGE 113
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
What are sediments?
PAGE 127
The way light reflects off of a mineral.
What is luster?
PAGE 112
Includes shells, bones,leaves, stems, and other remains of living things
What does sediment include?
PAGE 126
The three categories all rocks can be put into
What are igneous, sedimentary, and metamorphic?
PAGE 113- 114
This kind of igneous rock is formed when magma cools beneath the Earth's surface.
What is Intrusive igneous rock?
PAGE 121
These are two ways that sediments are formed.
What is weathering and erosion?
PAGE 127
The scale that is used to measure the hardness of minerals
What is Moh's Hardness Scale?
PAGE 112
Small, solid pieces of material that come from rocks or living things
What is sediment?
PAGE 126
A rock that was sediment, then went under pressure, then was melted down and crystalized or cooled inside a volcano is this type of rock.
What is a igneous rock?
PAGE 113
This type of igneous rock forms when lava cools on the Earth's surface.
What is Extrusive igneous rock?
PAGE 120
These 2 things cause metamorphic rocks to form.
What are heat and pressure?
PAGE 135
Another way to identify minerals, it leaves the color of the powder behind when rubbed against a rough white tile
What is streak?
PAGE 113
Water or wind loosen and carrie away fragments of rock
How does sediment move?
PAGE 126
These types of rocks can become sediment by weathering
What is any type of rock?
PAGE 113
This type of igneous rock is black with a glassy texture.
What is obsidian?
PAGE 120
For an Igneous rock to become a sedimentary rock, what needs to happen?
What is weathering, erosion, compaction, and cementation?
PAGE 119
The property that causes a mineral to glow under ultraviolet light
What is flourescent?
PAGE 112
Running water, wind, and ice
What are three forces that carry sediment?
PAGE 126
This is formed when clay goes under a lot of heat and pressure.
What is slate?
PAGE 126
This determines the size of crystals that form in igneous rocks.
What is the cooling rate of the magma or lava?
PAGE 113
The type of sedimentary rock that can contain fossils.
What is organic sedimentary?
PAGE 129
You can see this property just by looking at a mineral. Many minerals can be several of these.
What is color?
PAGE 112
When it is deposited by water and wind.
When do sedimentary rocks form?
PAGE 126
This is how rocks on the surface get pushed into the Earth's core
What is pressure?
