100
a mountain that opens downward to a pool of molten rock below the surface of the earth.
What are volcanoes?
100
Plates are located in this layer

What is sedimentary rock
300
Outer solid layer and is where life as we know it exists
What is the crust?
300
Made up of all of the Earths physical materials such as rocks and soil

What are dormant volcanoes?
300
What is the theory of pangea?
The continents were all joined together but broke apart due to plate movement.
300
forms from another rock due to change in heat or pressure
What are metamorphic rocks
400
Made up of molten rock
What is the mantle
400
Made up of all the Earth's water
What is the hydrosphere?
400
volcanoes that have not erupted in a while and will most likely not erupt ever again.
What are extinct volcanoes?
400

What is the atmosphere
500
Why do volcanoes occur?
Plate movement
500
What can result from plate movement?
Earthquakes and Volcanoes
500
When rocks and sediments are picked up and moved to another place by ice, water, wind, or gravity
