Miscellaneous
100
The center layer of the Earth.
What is the core?
100
Plates move past each other in opposite directions.
What is a transform fault boundary?
100
Most earthquakes occur along this type of boundary.
What is a convergent boundary?
100
A famous tranform fault boundary.
What is the San Andreas Fault?
100
This layer is divided into 7 plates.
What is the lithosphere?
200
The Earth's middle layer.
What is the mantle?
200
Plates move away from each other, magma pushes up and lava forms new crust.
What is a divergent boundary?
200
This measures the energy released from an earthquake on a scale of 1-10.
What is the Richter Scale?
200
This collision at a convergent boundary formed the Andes Mountains and Mt. St. Helens.
What is happens when an oceanic plate collides with a continental plate?
200
Most of this type of boundary is in the oceanic crust.
What is a transform fault boundary?
300
The Earth's outer layer.
What is the crust?
300
Where divergent boundaries occur.
What is continents and ocean floor?
300
This measures the amount of damage an earthquake causes on a scale of I-XII?
What is the Mercalli Scale?
300
This collision at a convergent boundary formed the Mariana Trench.
What is what happens when one oceanic plate collides with another oceanic plate and one of the plates is pushed under the other.
300
Both of these happen when plates spread apart and new sea floor is formed.
What are sea-floor spreading and rifts?
400
Part of the upper mantle. Heat from the core cause currents here.
What is the asthenosphere?
400
Where oceanic and continental plates collide.
What is a convergent boundary?
400
This is the point in Earth's crust where the first major movement occurs.
What is the focus?
400
This collision at a convergent boundary formed the Himalayan Mountain Range.
What is what happens when 2 continental plates collide and one is forced under the other?
400
This is the name scientist gave the continents 225 million years ago.
What is Pangea?
500
This layer floats on the asthenosphere and includes the Earth's crust and the upper mantle.
What is the lithosphere?
500
This happens to the ocean floor at a convergent boundary.
What is moves down into the asthenosphere?
500
This point is on the Earth's surface directly above where the first movement occurs during an earthquake.
What is the epicenter?
500
This was formed at a divergent bounday and goes through all of the oceans for 52,000 miles and across Iceland.
What is the Mid-Ocean Ridge?
500
The 3 types of earthquake waves.
What are P-waves, S-waves and surface waves?
