Earth’s Layers: 1 point

Through its spinning Earth has a magnetic field.

What is the inner core?

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.

What is the inner core?

Earth’s Layers : 4 points

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.

What is the Sonar?

Extra, Extra : 1 point

This happens when you touch a hot pot or pan and the heat goes from the pot to your hand.

What is heat transfer?

Extra, Extra : 2 points

A rock that is preserved with a trace of an ancient organism.

What is a fossil?

Extra, Extra : 3 points

This transfers heat within a fluid.

What is convection currents?

Extra, Extra : 4 points

The transfer of heat through space.

What is radiation?

Extra, Extra : 5 points

When the heat source is removed from a fluid, what happens to the convection currents?

What is they eventually stop?
