About twelve of these rest on the mantle of the Earth.
What are plates?
100
This is a theory that Earth started as this.
What is a landmass?
100
These are two different kinds of glaciers.
What are continebt and valley glaciers?
100
This is anlother name for the "crust" of the Earth.
What is lithosphere?
100
Erosion has to do with this.
What is gravity?
200
This is responsible for movement beneath the plates.
What are convection currents?
200
Hawaiian islands example of island formations from this.
What are volcanoes?
200
this helps the glacier move.
What is slush?
200
This is composed of silicon, oxygen, magnesium, iron, aluminum, and calcium.
What is the mantle?
200
This is a very slow erosion.
What is a creep?
300
Most volcanoes and earthquakes are located here on the plates.
What are fault lines?
300
This is an example of movement of the Earth.
Where is Lake Mead, Nevada?
300
Lots of these are packed tightly into a glacier.
What is ice and snow?
300
this is nearly pure iron, hot enough to be molten, but because of high pressure it is forced into a metallic state.
What is the inner core?
300
This occurs when a rock is carried away from where it was weathered.
What is erosion?
400
Most volcanoes and earthquakes occur here.
Where is Asia?
400
Glaciers shape this as it moves.
What is the land?
400
this is made of iron liquid.
What is outer core
400
this is a very fast erosion.
What is a rockslide?
500
When plate tectonics collide, they cause these.
What are ocean basins, islands, mountains, earthquakes, and volcanoes?
500
This included all the landmasses of the earth before the Triassic Period.
What is Pangaea?
500
Glaciers move at this distance every day.
What is one or two feet?
500
This consists of igneous rock along with smaller amounts of metamorphic and sedimentary rock.
What is the crust?
500
This is what erosion means.
