Uplift- the process in which ____________ are formed.
Transform boundaries create faults.
TRUE (explanation graded)
What does the word diverge mean?
Split apart, move away
What is one feature of a divergent boundary?
-Rift valley
-New lithosphere created
-Mid-ocean ridges
How many continents are there?
7
Convergent boundaries: two ____________________ moving towards each other or _________
tectonic plates, colliding
(will accept crashing)
Underwater valley ranges are called mid-ocean ridges.
FALSE, teacher graded
Crash, collide, run into (may be more)
What is one feature of a transform boundary?
Earthquakes, faults
What layer of the Earth does convection currents occur in?
Mantle
Ocean __________- undersea _______ that are the _________ parts of the ocean.
trenches, valleys, deepest
The highest amount of earthquakes occur at convergent boundaries.
TRUE, explanation graded
Explain how earthquakes occur
Teacher graded

Teacher graded
The process of cold molecules __________ and warm molecules __________ is called ___________.
Seafloor spreading creates the deepest parts of the ocean.
FALSE, teacher graded
Which two boundary types do NOT have volcanoes? (must include type)
Convergent (2 continental plates)
Transform
What is an example of transform boundaries (CANNOT USE NOTES)
San Andres Fault
The Earth is approximately _____ years old (must have 3 decimal places)

Without any hints, what is the definition of subduction?
Subduction- sinking movement of ocean floor back into the mantle
(does not have to be exact but should mention ocean floor for full points, "earth" or "rock"= half points)
Continental and oceanic plate collision creates subduction.
True, explain why teacher graded
