This is the name for the super-continent that existed 300 million years ago.
What is Pangaea?
100
The three types of faults
What are normal, strike-slip, are thrust?
100
New crust is formed at this type of boundary as the tectonic plates move away from each other.
What is a divergent boundary.
100
This type of volcano has steep sides made by the accumulation of rock fragments during eruptions.
What is a cinder cone volcano?
200
This layer is liquid metal.
What is the outer core?
200
He was the scientist who proposed the Theory of Continental Drift.
Who was Alfred Wegener?
200
An instrument that is used to detect and record earthquakes
What is a seismograph or a seismometer?
200
Mountains are formed as tectonic plates at this boundary collide.
What is a convergent boundary?
200
This land feature is formed when hot liquid rock moves to Earth's surface.
What is a volcano?
300
The outer part is solid and rigid, but becomes soft and easily deformed.
What is the mantle?
300
Why Africa and South America are the best example for this piece of evidence
What is the shape of those continents fit together like puzzle pieces?
300
These seismic waves travel quickly and are the first to arrive at seismic stations. They are compression waves, and travel through solids, liquids, and gases.
What are P-waves (Primary Waves).
300
Earthquakes occur as the tectonic plates slide past each other horizontally at this type of boundary
What is a transform boundary?
300
Gentle slopes and nonviolent eruptions distinguish this type of volcano from other volcanoes.
What is a shield volcano?
400
This layer is solid metal and its spinning creates Earth's magnetic field.
What is the inner core?
400
Two pieces of evidence for Continental Drift
What are fossils and shapes of the continents?
400
These seismic waves travel more slowly than P-waves and arrive at seismic stations 2nd. They move side-to-side, and travel ONLY through solids.
What are S-waves?
400
A rift valley may form as two continental plates at this type of boundary move away from each other.
What is a divergent boundary?
400
The distribution of volcanoes around the Pacific Plate boundary
What is the "Ring of Fire?"
500
This is the term used to describe the crust and solid upper part of the mantle.
What is the lithosphere?
500
These seismic waves are the slowest seismic waves and arrive last at seismic stations. The waves cause the ground to move up and down. They are the MOST destructive seismic waves.
What are L-waves (Surface Waves).
500
Subduction occurs at this type of boundary.
What is a convergent boundary?
500
This is the term used to describe the plastic-like layer of the Earth.
