Bell Work Pick a science word and write the definition. Chapter 7 or glossary

2 Title of Notes: Plate Boundaries pg. 15 & 16 RS
Goal for lesson: I can describe the 3 plate boundaries. Write on your self assessment sheet.

3 Goal for lesson: (Learning target) I’ll know I’ve got it when…
I can describe the three plate boundaries. Today I am… Learning about how tectonic plates move relative to one another. So that I’ll be able to… understand how the plates move and the effects of those movements. I’ll know I’ve got it when… I can draw the three tectonic plate boundaries.

4 All tectonic plates have boundaries with other plates.

5 Convergent Divergent Transform
Three boundary types: Convergent Divergent Transform

6 Two tectonic plates push towards one another.
Convergent boundary Two tectonic plates push towards one another.

7 Convergent Plate Boundary - Oceanic
The denser plate subducts under the less denser plate Convergent Plate Boundary - Continental Animations from geology.com A powerful collision occurs . Himalaya Mountain Range is a good example.

8 Convergent boundary Geological features
Continental / Continental: Mountains Himalayan Mountain Range Oceanic / Oceanic (Subduction): Trenches and islands Aleutian Islands and the Mariana Trench Continental / Oceanic (Subduction): Trenches and volcanoes The two continental plates collide and both of them have a density that is much lower than the mantle, which prevents subduction (there may be a small amout of subduction or the heavier lithosphere below the continental crust might break free from the crust and subduct).

9 Real-world connection:
Himalayas – Convergent boundary Mt. Everest – 26k feet at summit

10 The Himalayan Mountains are found in India, Nepal, Bhutan and Tibet!

11 Two tectonic plates move away from one another.
Divergent Boundary Two tectonic plates move away from one another.

12 Real-world connection:
Great Rift Valley (Africa) – Divergent boundary Ethiopia, Kenya, and Tanzania – rift: crack in something, 3,700 miles long

13 Divergent boundary Geological features
Oceanic: Mid-ocean ridges Mid-Atlantic Ridge Continental: Rifts / Rift valley Great Rift Valley (Africa)

14 Two tectonic plates slide past one other horizontally.
Transform Boundary Two tectonic plates slide past one other horizontally.

15

16 Real-world connection: Pacific plate and North American plate – Transform boundary (San Andreas Fault)

17 Earthquakes San Andreas Fault and Alpine Fault
Transform boundary Earthquakes San Andreas Fault and Alpine Fault

18 Subduction zone: The area where an oceanic plate sinks down into the Asthenosphere at a convergent boundary.

19 Notebook activity pg. 15 LS
Create a bubble map for the 3 plate boundaries: For each boundary include: Brief description of the boundary Picture showing what occurs
