Vocabulary
Magma
Molten (melted) or partially molten rocks that is still underground
Convergent
When two plates move towards each other and collide
Are currently erupting or could erupt at any time
Crust
Where are earthquakes most common in the United States?
California
Causation
The reason something has occurred or is occurring.
Divergent
When tectonic plates move apart
Dormant
Have not erupted for a long time but could erupt again
Magnitude
A measurement of the size and power of an Earthquake.
True or False
Magma is underneath the ground, lava is what comes out of the volcano
Correlation
Two things or events happening together or at the same time, but not causing one another.
Transform
When plates slide past/scrape one other
Extinct
Been a long time since it has erupted and very unlikely to erupt again
Subduction
The sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
What was Pangea?
A supercontinent that existed millions of years ago when all the continents were joined together.
Tectonic Plates
The large, thin, relatively rigid plates that move relative to one another on the outer surface of the Earth.
At which two plates are earthquakes most common?
Convergent and Transform
Name three types of volcano's (shape)
Shield, Composite, Cone
Sediment
Loose earth materials, such as sand, soil, and rocks, found on the surface of the Earth.
Explain how fossils are made
When a dead organism, usually an animal with hard parts like bones or shells, is quickly buried by sediment like mud or sand and turns into rock over time
Volcano
A mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust.
Which two plates form a volcano?
Convergent and Divergent
Hawaii
Plate Tectonics
The theory that the Earth's outer shell is divided into several plates that move and interact with each other.
What is erosion?
The process of moving soil and rock by water, wind or glacial action.
