Plate Boundaries
100
This is a geological theory that states that pieces of Earth are in constant, slow motion.
What is plate tectonics
100
This is the name of the giant supercontinent
What is Pangea
100
This is a mountain that forms when magma reaches the surface of the Earth
What is a volcano
100
These types of faults form where rock is pulled apart by tension
What is a normal fault
100
These occur when two plates collide forming mountains
What are folds
200
These are sections of the Earth's crust or lithosphere
What are plates
200
These were found on several different continents
What are fossils
200
This is a molten mixture of rock forming substances, gases and water from the mantle
What is magma
200
This type of boundary is where two plates move past each other in opposite directions
What is a transform boundary
300
These rise and fall within the mantle.
What is convection currents
300
The same types of these were found on both Africa and South America
What are rocks
300
When magma reaches the surface it is called
What is lava
300
This type of fault forms where compression pushes the rock of the crust together
What is a reverse fault
300
At this type of boundary two plates move away from each other
What is a divergent boundary
400
This is made up of the crust and the upper mantle
What is the lithosphere
400
These are evidence that Africa was once cold
What are glacial deposits
400
This is one major belt of volcanoes
What is the ring of fire
400
The rocks in this type of fault slip past each other and have little up or down motion
What is a strike-slip fault
400
This type of convergent boundary is where the sea floor is forced down into the mantle.
What is subduction
500
The plates of the lithosphere float on top of this.
What is the asthenosphere
500
This is an underwater mountain range
What is the mid-ocean ridge
500
an area where material from deep within Earth's mantle rises to the crust and melts to form magma
What is a hot spot
500
These are the 3 types of stress forces that are created by Earth's movement
What are tension, compression and shearing
500
This type of convergent boundary can occur between any type of crust.
What is a collision
