Offset of streambeds/landscape
100
Define theory
An idea mostly proposed as true that is supported by a great deal of evidence.
100
Define tsunami
The effect of a large displacement of water after an earthquake on the ocean floor that forms large, destructive waves.
200
What were Earth's layers like before differentiation?
Mostly the same
200
What are the three processes proposed of how Earth's plates move?
Mantle Convection, Slab Push, Ridge Pull
200
What types of land forms occur at continental-continental divergent plate boundaries?
Fault-Block Mountains Rift Valleys
200
Define Continental Drift
The theory that the continents were once one land mass.
200
Define Rifting
The pulling apart of the lithosphere to form faults and cracks in the Earth's surface.
300
What type of energy did the particles that made up Earth's molten state have?
Gravitational Potential Energy
300
What is it called when the magnetic particles in newly forming rock move when Earth's poles switch?
A Magnetic Reversal Pattern
300
What types of land forms occur at continental-continental convergent plate boundaries?
Folded Mountains Volcanoes Ocean Trenches
300
Define Subduction
The movement of one plate over the other. The subducting plate will melt in the mantle.
300
Define block
A large chunk of Earth that moves up or down. Occur at divergent boundaries.
400
What keeps the Earth's core molten?
Radioactive Decay
400
Who suggested that Pangaea was separated into Laurasia and Gondwana?
Alexander du Toit
400
What is the channel of magma under a volcano called?
A conduit
400
Define Differentiation
The movement of denser materials towards the center of an object and the less dense move out.
400
Define Deformation
The bending, stretching, tilting, and breaking of rock.
500
How did the Earth form?
Gas and dust began to pull together and began to form Earth.
500
Who proposed the theory of ___________ _____ in 1912?
Alfred Wengener
500
What are the types of plate boundaries and their faults?
Divergent - Normal Convergent - Reverse Transform - Strike-Slip
500
Define Seismic Waves and what types are there? Describe.
Waves that travel through rock. Primary waves travel through solids, liquids, and gases. Secondary Waves travel through only solids.
500
Define Xenolith
A chunk of upper mantle that gets caught in a volcanic eruption and is brought to the surface.
