A naturally occurring solid with a definite structure.
What is a Mineral
100
Rocks go through this process to become magma.
What is melting?
100
These rocks are made of bits and pieces of rocks clumped together.
What are sedimentary rocks?
100
This is another name for Volcanic Rock, or rocks made from molten rock that has hardened.
What is Igneous Rock.
100
The name of this type of rock comes from the meaning "to change."
What is Metamorphic Rock?
200
How easily a mineral can be scratched.
What is hardness.
200
Rocks become this after they are weathered and eroded.
What is Sediment?
200
The weight over a given area which presses down on something.
What is pressure?
200
This is what we call Igneous rocks that form under the surface of the earth.
What is Intrusive?
200
These three things can cause rocks to change into different rocks.
What are heat, pressure, and chemical reactions?
300
This property is how a mineral reflects light or how shiny it is.
What is luster?
300
When magma cools, this is the type of rock we get.
What is Igneous Rock?
300
When minerals are dissolved by water, they can make this which helps rock particles stick together.
What is glue.
300
This is what we call Igneous rocks that form above the surface of the Earth.
What is Extrusive?
300
These are the boundaries where metamorphic rocks are usually found because there is a lot of pressure from plates colliding and heat from magma below the crust.
What are Convergent Boundaries?
400
This property is its color when it is ground into a powder or scraped across a porcelain plate.
What is streak?
400
These are the two main forces that change rocks into metamorphic rocks.
What are Heat and Pressure?
400
When minerals are dissolved in water and then the water evaporates, the minerals can form these.
What are crystals.
400
This is a type of Igneous rock that formed above the surface of the earth and has a glassy texture.
What is Obsidian?
400
When rocks change into different rocks, they do not do this even though they are heated up a lot.
What is melt?
500
These are the three levels of "texture."
What are Course, Fine, and Glassy.
500
These are the two processes that happen to sediment when it becomes Sedimentary rock.
What are Compaction and Cementation?
500
This rock is made up of materials that were once parts of living ocean animals.
What is Limestone?
500
This rock formed below the surface of the earth and has a course texture. It is typically made up of fledspar, mica, hornblende, and quartz.
What is Granite.
500
This type of rock is a "nice" example of a metamorphic rock that has easily visible layers.
