Miscellaneous
100
Layer of the Earth that is liquid due to intense heat
What is the outer core?
100
The theory that explains the main cause of mountain building, earthquakes, and volcanic eruptions.
What is the theory of plate tectonics?
100
Can cause a rapid change on Earth's surface.
What is an earthquake?
100
The crust floats on the mantle. Explain its density.
What is the crust is less dense and floats?
200
A dense, hot layer of partially solid rock
What is the mantle?
200
Type of boundary that forms when two ocean plates move away form each other
What is a divergent boundary?
200
Landform that is created when two continental plates meet.
What is a mountain range?
200
The source of energy that drives plate tectonics, earthquakes, and volcanic eruptions
What is energy from Earth's molten layers?
300
This layer of the earth has the same temperature as the surface of the Sun
What is the inner core?
300
Explain what causes the movement of tectonic plates
What is heat transfers from the core and creates currents in the mantle?
300
This drives the movement of Earth's tectonic plates to create earthquakes and volcanoes
What is the convection of magma which pulls the plates?
300
Landform that forms as the Earth rotates on its axis and cause plates to move down
What is large valleys?
400
Layer of the Earth that can show what happens to heat as water boils
What is the mantle?
400
When looking at a model of the Earth, it's the place where earthquakes are likely to occur
What is along cracks where pieces can rub and grind against each other?
400
The place where active or extinct volcanoes are least likely to be found
What is the middle of continental plates?
400
This image shows...
What is two magma cells coming together and pulling one plate below the other?
500
The layer of Earth that can cause earthquakes and volcanoes
What is the lithosphere and part of upper mantle?
500
New evidence that scientists use to support the theory of plate tectonics
What is samples of rock from the ocean floor that increase in age as you move away from the mid-ocean ridge
500
This landform formed when plates moved away from each other and allowed magma to flow up and out from the rift to fill the gaps and spread the ocean floor
What is the mid-ocean ridge?
500
What is happening in the mantle?
What is magma is heated by the core causing it to rise toward the crust then sink as it cools (convection)?
