This type of rock comes from volcanic eruptions (magma/lava):
What is IGNEOUS ROCK?
100
Sand and small pieces of rocks, pebbles, mineral grains, and shells are called this:
What are sediments?
100
If a rock is changed by Heat and Pressure, the new rock is called this:
What is Metamorphic Rock?
100
This property describes how easily a mineral can be scratched.
What is 'hardness'?
100
This process moves takes away sediment from one place and brings it to another place.
What is Erosion?
200
A. This kind of igneous rock is formed when magma cools INSIDE the Earth's surface.
B. This kind of Igneous Rock is formed ON the surface of the earth:
What is Intrusive Igneous Rock?/ What is Extrusive Igneous Rock
200
They are the three types of rock.
What are Igneous, Sedimentary and Metamorphic?
200
True or False: A mineral can scratch any mineral that is harder than itself:
What is 'FALSE'?
200
This property describes how the surface of a mineral reflects light:
What is Luster?
200
This kind of weathering breaks down rock without changing its composition.
What is mechanical weathering?
300
These rocks are made up of particles of rock, shells and soil.
What are sedimentary rocks?
300
This rock forms when small pieces of rocks, pebbles, shells and soil become compacted and cemented?
What is Sedimentary Rock?
300
Color is not very helpful in identifying minerals because of these two things:
1. Many minerals are the same color. (Ex. Many are white.)
1. Some minerals come in a variety of colors. (Ex. Quartz comes in many colors.)
300
This leaves a powder on a ceramic plate and reveals the true color of a mineral:
What is streak?
300
This is the difference between Transparent and Translucent:
Transparent you can see light AND details through mineral.
Translucent you can only see light through mineral.
400
This process describes how rocks continually change from one type of rock into another.
What is The Rock Cycle?
400
In the Rock Cycle, this rock type may be weathered to become sediment.
What are All Rock Types?
400
When four rock layers lay on top of one another, the OLDEST fossils are in this rock layer:
What is the BOTTOM layer?
400
This is a nonliving, naturally occurring crystalline solid:
What is a mineral?
400
If any rock melts and then cools and hardens, it is this type of rock.
What is an igneous rock?
500
This is a solid material made up of one or more minerals:
What is a ROCK?
500
This rock type is much more likely than other rock types to contain fossils.
What are sedimentary rocks?
500
These are 2 examples of how our earth changes continuously:
Any 2 of the following: What are mudslides, landslides, the Rock Cycle, any of the 'actions' in the Rock Cycle.
500
True or False: Gasoline is a mineral.
What is false? (Minerals must be SOLID!)
500
If a sedimentary rock is buried deep in the earth and subjected to intense heat and pressure, but does not melt, it becomes this type of rock.
