Just how many layers of the Earth are there anyway?
If the Earth's crust really moves, how come I can't see it?
Weathering is only crust deep...
Just how many different types of rocks can there be?
So...how much do you really think you know about the Earth?
100
The layer that surrounds the earth and protects it from too much sunlight.
What is the atmosphere.
100
This theory says that the earth's surgace is made up of about 20 moving pieces.
What is plate tectonics.
100
This is weathering.
What is the breaking down or changing of rock.
100
During the rock cycle, rocks do this.
What is change.
100
A guess or idea.
What is hypothesis.
200
Rocks, soild and minerals are all a part of this.
What is the lithosphere.
200
Name something that can be caused by plate movement.
What is mountains, earthquakes, or volcanoes.
200
This is when the weathered rock and soil is moved or carried.
What is erosion.
200
Remains of any dead organism trapped in layers of rocks, if they make it there.
What is fossils.
200
When wind carries sand and then drops it, this can form.
What is a dune.
300
The outer part of the lithosphere is called this.
What is the crust.
300
Scientists gave this name to the continents. It's when they were one giant land mass.
What is Pangea.
300
The number on cause of erosion.
What is water.
300
This rock is from by the mantle, melted and then cooled.
What is igneous rock.
300
This specific type of sedimentary rock is made from shell parts that have been pressed and cemented.
What is limestone.
400
The Earth's lakes, oceans and rivers are part of this.
What is the hydrophere.
400
Plate tectonics is really this...supported by evidence of course.
What is a theory.
400
Water drops eroded materials during this process.
What is deposition.
400
This rock is simply solid particles cemented together.
What is sedimentary rock.
400
**DOUBLE DOUBLE DOUBLE**
This is the proper name of the hardness scale in regards to minerals.
What is the Mohs Hardness Scale.
500
This is between the crust and the core.
What is the mantle.
500
This is how scientists think the Earth's crust moves.
What is the heat below the mantle pushes up and cools. This continuous action causes the crust to move under the pressure.
500
This is formed during deposition.
What is a delta.
500
Igneous or sedimentary rock can become this when changed by heat or pressure.
What is metamorphic rock.
500
This is how rocks show that changes take place on Earth.
What is through the rock cycle. Igneous rock, made by the mantle, can be broken down to sand. This sand is pressed into sedimentary rock, which finally become metamorphic rock when heated.
