When the Earth spins on its axis. (24 Hours)
What is Rotation?
100
The theory that states that the continents have been moving all throughout the Earth's history.
What is Continental Drift?
100
A region surrounding the Pacific Ocean where the majority of the Earth's earthquakes and volcanoes occur.
What is The Ring of Fire?
100
Any structure that moves magma to the surface.
What is Volcano?
100
Rocks form from the cooling and crystalizing of magma.
What is Igneous Rocks?
200
The two dates per year when the sunlight directly strikes highest in the northern and southern hemisphere.
What is Solstice?
200
The proposed supercontinent that existed 200 million years ago.
What is Pangaea?
200
The point under the surface where earthquakes occur, and plates fault.
What is The Focus?
200
Large volcanoes that produce Pyroclasts, and mostly explode.
What is Stratovolcano?
200
Substances that are solid, inorganic, and occur naturally.
What is Minerals?
300
The orbit of the Earth around the sun.
What is Revolution?
300
Thick, light crust located on land
What is Continental Crust?
300
The point on the surface that is directly above the Focus.
What is Epicenter?

The scale of amount of damage caused by an earthquake.
What is Mercalli Intensity?
400
The process where one plate moves underneath another, leads to the formation of volcanoes.
What is Subduction?
400
1-10, softest – hardest
What is Mohs Hardness Scale?
500
The Earth's shape, slightly wider at the equator due to rotation.
What is An Oblate Spheroid?
500
The movement of heat through the asthenosphere which causes plates to move. (causes plate tectonics)
What is Convection Currents?
