Tectonic Plates, Boundaries, Faults etc.

1. Review
• The Earths Interior.
• What vegetable is Earth like? Why?
• List the 4 main layers!
• What are the 3 layers of the Mantle?
• Lithosphere
• Asthenosphere
• Mesosphere

2. Tectonic Plates
• What is a Plate?

3. GroupWork!
• 6 Groups of 4!
• Find and explain what are:
• 1. PlateTectonics
• 2. Faults
• 3. RiftValley
• 4. Divergent Boundaries
• 5. Converging Boundaries
• 6.Transform Boundaries

4. PlateTectonics
• Small breaks, around the Earth.
• Made of solid rock.
• Under the plates is a weaker layer of partially melted rocks.

5. Continental Drift
• Slow movement of continents because the plates are moving due to the
rotation of the Earth.

6. Fault Lines
• Movement ofTectonic Plates.
• Causing a break in the ground.
• This makes Earthquakes!

7. Boundaries
• Where Plates meet.
• There are 3Types:
•Divergent
•Convergent
•Transform

8. Divergent Boundaries
• Diverge means Move Away.
• Occurs mainly along ocean ridges.
• Can cause volcanic eruptions.
• But! It does not make volcanoes!

9. RiftValley
• A divergent boundary on land.
• Creating a valley.

10. Convergent Boundaries
• Converge means Meet/Collide.
• The heaviest plate pushes the lighter plate up.
• This makes:
• Mountains
• Volcanoes
• Tsunamis
• Earthquakes

11. Transform Boundaries
• Where two plates “swap”.
• The plates go past each other
• BUT some parts are not even and hit off each other.
• This makes really big earthquakes.

12. Group Work 2!
• Choose a boundary result.
• As a team make a small presentation about this formation.
• Examples include: Mountains,Tsunamis,Volcanoes, Earthquakes & Rift
Valleys.
• You have 10 minutes to make a presentation… GO!
