A drawing of what you see when you cut through an object
What is a Cross Section
100
The process in which the sea floor slowly increases in size due to the formation of new crust
What is Sea Floor Spreading
100
Plates move toward each other and collide
What is a Convergent Boundary
100
These are the three types of rock families
What is Igneous, Sedimentary and Metamorphic
200
When chemical changes dissolves the minerals in rocks or change the minerals into different minerals
What is Chemical Weathering
200
Deep slope in the seabed between a continental shelf and the sea floor
What is a continental shelf
200
Using a device that sends out sound waves and records how long it takes for that sound wave to come back
What is Sonar Technology
200
Plates slide past each other
What is a Transform boundary

Each process in this cycle can take thousands of years to occus.
What is the Rock Cycle
300
When rocks are broken apart by physical processes.
What is Mechanical Weathering
300
An opening in the oceanic crust, where molten materials can escape
What is a rift
300
A long cylindrical sample of rock
What is a Core Sample
300
Sea floor spreading occurs here
What is a Divergent Boundary
300
The evidence Wegener had to support his theory of continental drift
What is Fossil evidence, Climate change and Rock evidence
400
Chemical weathering occurs when rocks reacts to this
What is Acid Rain
400
Part of the sea floor which can be large enough to be considered an underwater mountain
What is an ocean ridge
400
A sensing device used to detect magnetic fields
What is a Magnetometer
400
Volcanoes form at a boundary where this occurs
What is a Subduction Zone
400
Mountains, volcanoes and earthquakes occur due to this
What is the movement of plates
500
Three causes of mechanical weathering
What is water and nutrients (plants), burrowing animals, water freezing in cracks in a rock
500
Theory proposing continents change position very slowly, moving a few centimetres every year.
What is the Theory of Continental Drift
500
An opening in the sea floor through which mineral-rich water escapes
What is a Hydrothermal Vent

The Juan de Fuca plate is being wired to learn more about plate tectonics, underwater earthquakes, whale migrations and changes in fish populations as part of this project
What is the NEPTUNE project
500
The theory of plate tectonics states plates interact here
