Plate tectonics
The lithosphere (crust) is divided into
tectonic plates
The movement of these plates is
what creates Earth’s crustal features

Types of boundaries
A boundary is where 2 tectonic plates
meet

Divergent Boundary
When tectonic plates move away from
each other
Crustal features: mid ocean ridges, rifts
Great Rift Valley
Mid-Ocean Ridge

Convergent Boundary
When an ocean plate collides with a
continental plate, the ocean plate sinks
under the continental plate (subduction)
Crustal features: trenches and volcanic
mountains

Transform Boundary
When 2 tectonic plates slide past each
other
Crustal Features: faults and earthquakes
San Andreas Fault
What to highlight
• You should not highlight everything, to
start, you will highlight/underline what is
in red
• What we are highlighting will help us
answer the essential question:
• What evidence supports the theory of
continental drift?
Creating questions
• Look at what you’ve highlighted
• What you have highlighted should be the
answer to your question
• We will do this together
