Topic: Earth’ss Features Topic: Earth Features Essential Question: What crustal features are created by the movement of Earth’s plates? Topic: Earth’s Features Essential Question: What crustal features are created by the movement of Earth’ss plates? the movement of Earth plates? Plate tectonics Plate tectonics The lithosphere (crust) is divided into tectonic plates tectonic plates The movement of these plates is what creates Earth’s crustal features h h’ lf Topic: Earth’s Features Essential Question: What crustal features are created by th the movement of Earth t f E th’s plates? l t ? Types of boundaries A boundary is where 2 tectonic plates meet Topic: Earth’s Features Essential Question: What crustal features are created by th the movement of Earth t f E th’s plates? l t ? Divergent Boundary Divergent Boundary When tectonic plates move away from each other Crustal features: mid ocean ridges, rifts Great Rift Valley Mid‐Ocean Mid Ocean Ridge Ridge Topic: Earth’s Features Essential Question: What crustal features are created by th the movement of Earth t f E th’s plates? l t ? Convergent Boundary Convergent Boundary When 2 continental plates collide Crustal features: mountains Crustal features: The Himalayas The Himalayas Topic: Earth’s Features Essential Question: What crustal features are created by the movement of Earth’ss plates? the movement of Earth plates? Convergent Boundary Convergent Boundary When an ocean plate collides with a continental plate, the ocean plate sinks p , p under the continental plate (subduction) Crustal features: trenches and volcanic mountains Topic: Earth’s Features Essential Question: What crustal features are created by th the movement of Earth t f E th’s plates? l t ? Transform Boundary Transform Boundary When 2 tectonic plates slide past each other Crustal Features: faults and earthquakes San Andreas Fault San Andreas Fault What to highlight What to highlight • You You should not should not highlight everything, to highlight everything to start, you will highlight/underline what is i in red d • What we are highlighting will help us answer the essential question: • What evidence supports the theory of What evidence supports the theory of continental drift? Creating questions Creating questions • Look Look at what you at what you’ve ve highlighted highlighted • What you have highlighted should be the answer to your question answer to your question • We will do this together Topic: Earth’s Features Essential Question: What crustal features are created by the movement of Earth’ss plates? the movement of Earth plates?

What is subduction? Convergent Boundary Convergent Boundary When an ocean plate collides with a continental plate, the ocean plate sinks p , p under the continental plate (subduction) Crustal features: trenches and volcanic mountains Topic: Earth’s Features Essential Question: What crustal features are created by th the movement of Earth t f E th’s plates? l t ? What crustal features are f found d att a transform boundary? Transform Boundary Transform Boundary When 2 tectonic plates slide past each other Crustal Features: faults and earthquakes Now let’ss write a summary Now let write a summary Look at each question you wrote on your own, and q y y , answer each question in a complete sentence. ‐What creates Earth’s features? ‐What is a plate boundary? ‐What crustal features are found at a divergent boundary? ‐What crustal features are found at a convergent What crustal features are found at a convergent boundary? ‐What is subduction? ‐What crustal features are found at a transform boundary?
