True or False: The rock cycle is the process that rocks undergo to change from one kind to another.
True

A trace of plant or animal that lived a long time ago is called a ___________.
Fossil
200
True or False: The outer layer of the Earth is called the Mantle.
False. It is the crust.
200
This type of rock is created from weathering and erosion of bigger rocks.
Sedimentary Rocks
200
True or false: Minerals are made up of pure solid materials called rocks.
False. Rocks are made up of pure solid materials called minerals.

When an igneous rock is weathered, it becomes sediment. The sediment travels through rivers and streams an settles on the ocean floor. After many years it becomes this type of rock.
Sedimentary
200
Name three common uses for rocks.
Answers will vary.
300
The Mantle is mostly made up of what?
Magma or molten rock.
300
Hot lava cools from a volcano to form this type of rock.
Igneous Rock
300
When a mineral is classified by how shiny or dull it is, this is called _____________.
Luster
300
A Metamorphic rock is heated below the Earth's surface and becomes magma. When magma erupts from a volcano it flows down the side of the volcano and eventually cools. The type of rock that is formed from this process is:
Igneous Rock

Steve is scratching a piece of mineral with a nail. After the nail scratches the rock, Steve try unsuccessfully to scratch the mineral with a penny. Why is Steve doing this?
He is trying to identify the mineral using the Moh's Hardness Scale.
400
What happens when 2 tectonic plates on the Earth's crust collide, pull apart or rub together?
An Earthquake.
400
This type of rock is formed by heating and compression.
Metamorphic Rock
400
The classification of minerals by rubbing them on a ceramic plate to see if it leaves a trail is called what?
Streak Test
400
Igneous rock has been buried below ground and has a great amount of heat and pressure applied to it. It then becomes this type of rock.
Metamorphic
400
Igneous rock that forms inside the Earth is called _________ while igneous rock that forms on the Earth's surface is called ___________.
1) Intrusive 2) Extrusive
500
A _______ changes the earth's surface by creating cracks in the Earth and erupting.
Volcano
500
Pumice cools very quickly when it reaches the Earth's surface. What type of rock is pumice? How do you know?
Pumice is igneous rock because it has to cool which means it used to be magma that came from a volcano.
500
The testing of a mineral to see how hard or soft it may be is called __________.
Moh's Hardness Scale.
500
How does a sedimentary rock become igneous rock?
Sedimentary rock is pushed down below the Earth's surface where it is melted into magma. When the magma cools, it forms igneous rock.
500
Rocks that are found at the top of a mountain are similar to the sediments found on the bottom of a lake bed at the base of the mountain. How did this happen?
Rocks at the top of the mountain are weathered and eroded by wind or rain and carried by river or stream to the lake bed.
