Inside Story
100
the Earth's crust under the Oceans
What is Oceanic crust?
100
the mountain range caused by the collision of the Indian plate and the Eurasian plate
What are the Himalayas?
100
The San Andreas fault is this type of boundary
What is a transform boundary?
100
the large landmass that broke into pieces to form the tectonic plates
What is Pangaea?
100
The thinnest layer of the Earth
What is the crust?
200
These two violent events are usually near plate boundaries, caused by the plates' movement.
What are earthquakes and volcanoes?
200
This is a sudden release of energy in the Earth's crust, causing the ground to shake.
What is an earthquake?
200
This is what happens when a transform fault suddenly releases the pent-up energy it has stored
What is an earthquake?
200
this is formed along a fault where two oceanic plates are diverging
What is a mid-ocean ridge?
200
nickel and iron
What is the core of the Earth made of?
300
a mountain range formed where new ocean floor is being created by two divergent plates
What is a mid-ocean ridge?
300
This substance is known as magma when it is in the mantle and lava when it erupts from a volcano.
What is molten rock?
300
This is what is created when two continental plates collide
What is folded mountains?
300
this is created when an oceanic plate is being subducted under a continental plate, pulling the edge of the continental plate with it
What is a trench?
300
melted
What is molten?
400
the heat cycles of the molten rock in the mantle that cause the plates to move across the face of the Earth
What are convection currents?
400
Hawaii is being formed by volcanoes caused by this type of rupture in the Earth's crust
What is a hot spot?
400
the fault running the length of the west coast of the United States
What is the San Andreas Fault?
400
this is the area around the edge of the Pacific Ocean where many earthquakes occur and volcanoes erupt
What is the Ring of Fire?
400
the property of matter that causes one type of material to sink below another type of material, causing the layers of the Earth
What is density?
500
these are two types of convergent boundaries, one causing mountain-building and one creating volcanoes and trenches
What are subduction and collision?
500
Mt St Helens is an example of a volcano formed by this type of convergent boundary, where an oceanic plate is pushing toward a continental plate
What is a subduction zone?
500
the three main types of boundaries
What are transform, convergent, and divergent?
500
this is the type of plate movement that causes a severe up-and-down movement of continental or oceanic crust
What is a dip-slip strike?
500
The rigid part of the Earth including the crust and the upper mantle
What is the lithosphere?
