Earth & Theories
100
The type of boundary where earthquakes occur.
What is a transform boundary?
100
Hot molten rock found below the Earth's surface.
What is magma?
100
Where two plates collide.
What is a convergent boundary?
100
When two plates are moving towards one another and push upward, this type of mountain is created.
What is a folded mountain?
100
The outer layer of the earth made of layers of rock and soil.
What is the crust?
200
The first waves to travel from the focus of an earthquake. Can travel through rock and liquid.
What are Primary or P Waves?
200
Once magma reaches the Earth's surface.
What is lava?
200
A place where two plates are moving apart?
What is a divergent boundary?
200
When magma is forced up, but does not break through the crust, it cools and hardens to create this type of mountain.
What is a dome mountain?
200
The surface of the Earth is broken up into these.
What are plates?
300
The second type of wave to travel from the focus of an earthquake. This type can travel only through rock.
What is a Secondary or S Wave?
300
The place where magma collects inside a volcano.
What is the magma chamber?
300
A place where two plates slide past one another.
What is a transform boundary?
300
When blocks of crust on the sides of a fault move in opposite directions (up and down), this type of mountain is created.
What is a fault-block mountain?
300
A famous scientist, Alfred Wegener came up with this theory of how the continents seemed to shift.
What is the Continental Drift Theory?
400
An instrument used to tell where and how strong earthquakes are.
What is a seismograph?
400
A mountain with a vent at the top.
What is a volcano?
400
When one plate is forced under another.
What is subduction?
400
The name for the underwater mountain ranges.
What are the mid-ocean ridges?
400
Heat inside the mantle moves in these kind of cycles that are responsible for the movement of the plates.
What are convection currents?
500
A crack in the Earth's crust from extreme pressure and force.
What is a fault?
500
Place on Earth where most earthquakes and volcanoes occur.
What is the Ring of Fire?
500
The Mid-Atlantic Ridge is an example of this type of boundary.
What is a divergent boundary?
500
When an oceanic plate is subducted under a contintental plate, the continental plate is forced up and creates this type of mountain.
What is a folded mountain?
500
The two main types of metal that make up the core of the Earth.
What are iron and nickel?
