Plates/Layers of the Earth
Earthquake Waves
Results of Plate Movement
Continental Drift
Other
100
When two plates move away from each other. Nothing is destroyed, but new land is created, when magma oozes out of the mantle, create small underwater mountains.
What is a divergent boundary?
100
The primary earthquake wave. It is a body wave. Has a push and pull motion.
What is a p-wave
100
Volcanoes line the boundary of this plate.
Why is the pacific plate called the Ring of Fire?
100
The theory that continents were once a super continent by the name of Pangea.
What is the theory of continental drift?
100
An incredibly hot location in the mantle that continuously burns through the crust.
What is a hot spot?
200
When two plates slide past each other. The land is changed with bumps, ditches, wrinkles, bent rocks, or even twisted roads and homes.
What is a transform boundary?
200
The secondary earthquake wave. It is a body wave. Has a side to side motion. Also known as a transversc wave.
What is a s-wave
200
This was caused by a divergent boundary, and is an example of what it can create.
What is the Mid-Atlantic Ridge?
200
1.) The continents fit together like puzzle pieces. 2.) Mountain chains on different continents fit together. 3.) Fossils of the same animal can be found on different continents.
What evidence supports Pangea?
200
They are dense, and more heavy.
Why do oceanic plates sink into the mantle?
300
Colliding plates. Continental and continental plates create mountains when the land crinkles like paper. Oceanic and continental plates create volcanoes, when the oceanic plate sinks back into the mantle, causing it to overflow. Oceanic and oceanic plates create volcanic islands, when the older, denser plate recycles back into the mantle at the subduction zone.
What is a convergent boundary
300
They cannot travel through liquids.
What can a s-wave NOT travel through?
300
An example of a transform boundary.
What is the San Andreas Fault?
300
Alfred Wegener.
Who developed the theory of continental drift?
300
Vibrations in the earth caused by the sudden release of energy usually as a result of the movement of rocks along a fault.
What is an earthquake?
400
Crust- top layer, we live on it Lithosphere-made up of the crust and mantle. where the plates float. Asthenosphere-Top of mantle. Thick consistency. Mantle-Biggest layer made of magma Outer core-Liquid metal Inner core- solid metal
What are the layers of the Earth?
400
Based on which waves travel through which layer.
How do we know which layers of the Earth a liquid and which are solid?
400
An example of a convergent boundary,. one that involves two oceanic plates.
What is Hawaii
400
Convection currents in the mantle.
What causes the lithosphere to move?
400
A measurement used to measure the damage done by an earthquake.
