What are the layers of the Earth?
100
The THEORY that says the continents used to be big super continent.
What is Continental Drift?
100
A place where new ocean floor is created.
What is a Mid-Ocean Ridge?
100
The stress that causes a Normal fault to form at a divergent boundary.
What is tension?
100
The most active strike-fault in the United States.
What is the San Andreas Fault?
200
The coolest layer of the Earth.
What is the crust?
200
The name of the large super continent.
What is Pangea?
200
A place where the oldest ocean floor is subducted back into the mantle.
What is a subduction zone; forms trenches.
200
The break in the crust where the plates "go up and over" to form folded mountains.
What is REVERSE FAULT?
200
The Hawaiian Islands have calm, gentle eruptions.
What is a Shield Volcano?
300
The thickest layer.
What is the mantle?
300
The Glossopteris Fern, Mesosaurus Rex, and coal deposits.
What is fossil evidence located on different continents. Helped proved Wegner's Theory of Continental Drift.
300
A place on Earth's crust where tectonic plate boundaries collide.
What is a convergent boundary?
300
The stress located at Strike-slip Faults and Transform Boundaries.
What is shearing?
300
Mt. St. Helens erupted violently in 1980 but later eruptions have been very calm. What type of volcano is she?
What is a Composite Volcano?
400
The layer that has the most pressure and the highest temperature.
What is the Inner Core?
400
The shape of the continents helped Wegener prove his theory of Continental Drift.
What is Africa and South America.
400
A place in the Pacific Ocean where there is lots of tectonic movement.
What is the Pacific Ring of Fire?
400
The stress (tension) at this fault causes Fault-Block Mountains to form.
What is a Normal Fault?
400
A machine that detects movement within Earth's layers.
What is a seismograph machine.
500
The only liquid layer of Earth's layers.
What is the Outer Core?
500
This theory provided the "mechanism" for Wegener's Theory of Continental Drift to be proven true.
What is Sea Floor Spreading
500
A place on Earth's crust where plate boundaries "slide past" each other.
What is a Transform Boundary?
500
The land that drops when a normal fault divides.
What is a hanging wall.
