Earth’s Layers : 2 points
This is made of hot rocks.
What is the mantle?
Earth’s Layers : 3 points
This layer of the Earth is a dense ball of solid metal.

Sea-floor Spreading: 1 point
As your depth increases in the Earth, these increase.
What is temperature and pressure?
Sea-floor Spreading : 2 points
The supercontinent
What is Pangaea?
Sea-floor Spreading : 3 points
The process in which the ocean floor sinks through deep-ocean trench and back into the mantle.
What is subduction?
Sea-floor Spreading : 4 points
Evidence of sea-floor spreading is when molten material erupts from where?
What is the mantle?
Sea-floor Spreading : 5 points
Scientists do this to determine the age of rock samples.

What’s in a theory? : 5 points
Geological theory that states that pieces of Earth’s lithosphere are in constant, slow motion.
What is the theory of Plate Tectonics?
Ocean’s Middle: 1 point
The molten material from the mantle goes along here during sea-floor spreading.
What is the mid-ocean ridge?
Ocean’s Middle : 2 points
The longest chain of mountains in the world.
What is the mid-ocean ridge?
Ocean’s Middle : 3 points
These help geologists observe Earth’s interior by allowing them to study and record them.
What are seismic waves?
Ocean’s Middle : 4 points
Used to map the mid-ocean ridge.
