Boundaries
The three types of plate tectonics
What are convergent, divergent, and transform boundaries
The circulation patterns formed when less dense, warm material rises while more dense, cool material sinks.
What are convection currents?
The sum of all forces that act upon an object
What is a net force?
Earthquakes are formed by this kind of plate boundary
Where are transform boundaries?
You standing on earth is an example of this kind of force
What is gravity?
The plate boundary where two plates collide
What is a convergent boundary?
What is the mantle?
The ability to do work
What is energy?
Mountains are formed here
Where are convergent boundaries?
The decay radioactive elements undergo at a specific rate.
What is radioactive decay?
The type of boundary that forms new crust
What is a divergent plate boundary?
A force applied in one direction that is greater than the force applied in the opposite direction
What is an unbalanced force?
The force that keeps everything close to the center of the earth
What is gravity?
Subduction occurs at these plate boundaries.
Where are convergent boundaries?
Uranium
What is a radioactive element?
The type of boundary where two plates slide past each other

What is decreasing the mass of each plate? ***
Volcanoes are formed at these 2 plate boundaries
What are divergent and convergent plate boundaries?
The Afar region is impacted by this kind of plate boundary
What is divergent?
This separates the North American and Eurasian plates is causing the Atlantic Ocean to grow.

The breaking of a very massive plate into two smaller plates causes problems because...
- new land is formed (slowly)
- displacement of organisms
- natural disasters --> Earthquakes
- Formation of Oceans
********
Tsunamis occur at this plate boundary
