Igneous Rocks
This can cool and harden and form igneous rock.
What is magma or lava?
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
What are sediments?
The way light reflects off of a mineral.
What is luster?
Name the three types of rock groups.
What is Sedimentary, Igneous and Metamorphic?
The process of rocks changing from one kind of rock to another kind of rock over long periods of time.
What is the rock cycle?
This kind of igneous rock is formed when magma cools beneath the Earth's surface.
What is Intrusive igneous rock?
process that creates sediments
What is weathering
The scale that is used to measure the hardness of minerals
What is Moh's Hardness Scale
When mapping what geographic coordinates gets written first?
What is the Latitude N or S?
Difference between IV and DV
IV what is changed, DV what is measured
This type of igneous rock forms when lava cools on the Earth's surface.
What is Extrusive igneous rock?
These 2 things cause metamorphic rocks to form.
What are heat and pressure?
Another way to identify minerals; it leaves the color of the powder behind when rubbed against a rough white tile.
What is streak?
A naturally occurring, inorganic solid, that has a definite chemical composition and crystal structure.
What is a mineral?
What is the purpose of a control group?
What is for a comparison?
This type of igneous rock is black with a glassy texture. We looked at it in class.
What is obsidian?
For an Igneous rock to become a sedimentary rock, what needs to happen?
What is weathering, erosion, compaction, and cementation?
what characteristic of minerals affects its ability to either have a cleavage or a fractured break?
What is crystalline structure?
A hard substance composed of one or more minerals.
What is a rock?
explain how an igneous rock can become metamorphic?
Weathering and erosion, compaction and cementation, heat and pressure.
This determines the size of crystals that form in igneous rocks.
What is the cooling rate of the magma or lava?
which rock type has the highest densities? why?
What is metamorphic and molecules get packed closer together with high heat and pressure?
Hardness is directly related to what?
What is density?
Igneous rock that has fine-grained crystals
What is extrusive igneous rock?
The 6 properties of a mineral.
What is luster, streak, hardness, color and cleavage or fracture
