The movement of energy from a warmer object to a cooler object.
What is heat transfer?
100
A person who studies rocks and the Earth's forces.
What is a geologist?
100
A sudden violent shaking of the ground; can occur at any plate boundary.
What is an Earthquake?
200
The core is broken up into these two sections.
What are the outer and inner core.
200
Shapes the Earth by breaking down rock by a physical means (ex. Ice wedging)
What is physical weathering?
200

The study of the mgnetic properties of rocks that were determined by the earth's magnetic field at the time they were formed.

What is paleomgnetism?

200
What the seven land masses are called.
What are continents?
200
A well tested theory that explains a wide range of observations.
What is a scientific theory?
300
The layer made up of the crust and upper mantle.
What is the lithosphere.
300
The boundary that can create ridges when two plates move away from each other.
What is a divergent boundary?
300
The transfer of energy by the movement of a heated fluid; creates a cycle.
What is convection?
300
The type of crust below the ocean.
What is the oceanic crust?
300
The theory that states that pieces of the Earth's lithoshpere are in constant, slow motion, driven by convection currents in the mantle.
What is the theory of plate tectonics?
400
The main four layers of the Earth.
What are the crust, mantle, outer core, inner core?
400
The movement of weathered rock.
What is erosion?
400

An event in which the earth's magnetic field switched its orientation to the opposite of what it is today.

What is magnetic reversal?

400
A less dense rock that makes up much of the continents.
What is granite?
400
A break in the Earth's crust.
What is a fault?
500
The thinnest layer of the Earth.
What is the crust?
500
An area where one plate sinks beneath another plate due to density.
What is a subduction zone?
500
The 3 forces that combine to set convection currents in motion.
What are the heating and cooling of a fluid, changes in the fluids density, and the force of gravity?
500
The lithosphere is broken in these separate sections.
What are plates?
500
The three boundaries and what the places do at them.
What is are transform boundaries (plates move past each other), divergent boundaries (plates move away from each other), and convergent boundaries (plates move towards each other)?
