This is the outermost and thinnest layer of the Earth.
What is the Earth's crust.
100
This is a section of the lithosphere.
What is a plate?
100
This is the changing of materials in rock by a chemical process.
What is chemical weathering?
100
This force causes landslides.
What is gravity?
100
Name one of the six properties of minerals.
What is magnetism, hardness, streak, luster, shape, texture.
200
This is how scientists study about the Earth's mantle.
They study the material that is pushed up through the cracks in the Earth's crust.
200
This occurs when two plates jerk into a new position.
What is an earthquake?
200
This is the middle layer that makes up our soil.
What is subsoil?
200
These are formed when some areas erode more quickly than others.
What are harbors or inlets?
200
Melted rock that cools quickly will have...
What are small crystals?
300
This layer makes up the most of the Earth's material.
What is the mantle?
300
This plate boundary is where plates move apart.
What is a spreading plate boundary?
300
This is the process of breakign rock into smaller pieces by forces due to gravity.
What is mechanical weathering?
300
Wind blows sand up one side of a hill and pushes it over the edge. This makes the other side of the hill to become.
What is steeper?
300
Under high pressure and high temperatures this type of rock may form.
What is metamorphic rock?
400
In these currents cooler rock flows down while hotter rock flows up inside the Earth.
What are convection currents?
400
When an earthquake happens under the ocean it can often lead to this.
What is a tsunami?
400
These two types of rock, limestone and granite have different properties causing one to weather more quickly that the other.
What is limestone?
400
According to scientist Bill Nye, water, ice, wind, chemicals, and _________are constantly crumbling mountains.
What is sand?
400
This is a naturally made solid that has a regualr arrangement of particles in it.
What is a mineral?
500
This is where submarine canyons are likely to form.
What is the continental shelf?
500
This is the location where the plate slips.
What is a focus?
500
There are three layers that make up the soil.
What are topsoil, subsoil, and bedrock?
500
When water gets between the cracks of rocks and freezes it causes this to happen.
What is split open?
500
Younger rock can be found here.
What is at the surface?
