Earth's Layers
Plate tectonics
Mountains
Earthquakes
Volcanoes
100
This is Earth's uppermost layer
What is the crust?
100
Alfred Wegener is the fpunder of this thoery
What is the continental drift theory?
100
Compression at convergent boundaries cause these type of mountains to form
What are folded mountains
100
This is where the first motion of the Earthquake takes place
What is the focus?
100
this is melted rock found below the earth's surface
What is Magma?
200
This is the layer of Earth that is solid and made mostly of nickel
What is the inner core
200
These boundaries move away from each other
What is divergent boundaries?
200
Reverse faults got their name because of this
What is the hanging wall moves up in relation to the foot wall.
200
This is the return of rock to its original shape after deformation
What is elastic rebound?
200
This in an opening in a volcano
What is a vent?
300
These are the three most common elements in Earth's continental crust and oceanic crust
What are oxygen silicon and aluminum?
300
This is what happens at transform boundaries
What is two tectonic plates move horizontally past one another along Earth's surface, forming long fault lines
300
This is the process by which rocks change shape under stress
What is deformation?
300
At these boundaries the Earthquakes are the strongest
What is at convergent boundaries?
300
These volcanoes have a broad base and gently sloping sides. They can be found in Hawii
What is a shield volcano?
400
This is the physical layer of Earth that makes up the tectonic plates
What is the lithosphere
400
This is the name for super continent
What is pangaea?
400
These mountains form when tension makes the lithosphere break into many normal faults
What is fault block mountain?
400
These volcanoes commonly develop into large and steep mountains
What is composite volcanoes?
500
In the mantle this is what is making the plates move
What is convection?
500
At these boundaries tow tectonic plates collide with one another, causing subduction and /or mountain building
What is convergent plates
500
These are the three ways mountains are formed?
What is folding, volcanism and faulting?
500
This is a series of extremely long waves that can travel across the ocean at speeds of up to 800 km/h
What is a Tsunamis
500
These landforms look a lot a like but the first one forms at the base of a volcano and the other forms at the top of the volcano.
