Essential Question: What crustal features are created by
the movement of Earth’s plates?
Plate tectonics
The lithosphere (crust) is divided into
tectonic plates
The movement of these plates is
what creates Earth’s crustal features

Essential Question: What crustal features are created by

Types of boundaries
A boundary is where 2 tectonic plates
meet

Essential Question: What crustal features are created by
the movement of Earth’s plates?
Divergent Boundary
When tectonic plates move away from
each other
Crustal features: mid ocean ridges, rifts
Great Rift Valley
Mid-Ocean Ridge

Essential Question: What crustal features are created by
the movement of Earth’s plates?
Convergent Boundary
When 2 continental plates collide
Crustal features: mountains
The Himalayas

Essential Question: What crustal features are created by
the movement of Earth’s plates?
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
