Look at this map of earthquake and volcanic activity over the past 20 years or so. Write down 2 observations.

The top image shows the "puzzle pieces" of Earth's lithosphere. These are the pieces (aka plates) that move around. Write down 3 observations.
7
The dark line show the edges of the plates (pieces of earth's lithosphere) that move around. The arrows are showing the direction that these pieces are moving. Notice that there are three types of motion.
8
Multiple Select
Mark the different types of motion you see of the Earth's plates (pieces of lithosphere).
9
Milky Way Model of Earth!
Notice the top 3 layers of the Milky Way
Chocolate: breaks into pieces but solid
Caramel: moves but is thick and acts more like a solid
Nougat: solid and supports the caramel
10
Multiple Choice
Using the Milky Way model, which layer would represent which layer of Earth. Pick the correct match.
11
Multiple Choice
Okay in real life if we pull earth apart we don't get caramel....which option makes the most sense of what would happen when Earth is pulled apart?
12
Divergent Boundary
Plates/Lithosphere pieces move apart
Material from the asthenosphere fills the gap - we get lava/volcanic activity on the surface of Earth
At one point a divergent boundary started in KS - but then stopped! Maybe it will restart again?!
13
Multiple Choice
At divergent boundaries plates are moving away from each other. What happens in the space left between them?
14
Multiple Choice
What happens to the magma that comes up at divergent boundaries?

Poll
16
Multiple Choice
Next we are going to do the next motion with our model sliding one part of the chocolate one way and the other the opposite -but NOT pulling the candy apart.
Based on what you see on the surface of the chocolate, which option is most likely to happen on Earth's surface.
17
Transform Boundary
Notice the plates are still touching
One goes one direction, the other the opposite
This boundary is found in California!

Multiple Choice
Last motion is when the two plates collide! Looking at the model image, which option below is most likely to happen to Earth's surface?
21
Convergent Boundary
Plates Collide
Creates mountains, volcanic mountains, or volcanic islands (depending on what plates are colliding - will go into detail in another lesson
NW U.S. - Cascade Mountains are all volcanic mountains!!!
22
Multiple Choice
What is it called when plates push together?

Pangea
In the last lesson you were required to try to recreate how the continents were positioned about 240 million years ago.
The top image is present. The bottom shows you the correct answer - well a simplified version of it.
27
Poll
28
Multiple Choice
Looking at past to present, what type of boundary caused Africa & South America to get to their current positions?
29
Plate Tectonics
(formerly known as continental drift)
Earth's lithosphere is moving around
Movement of heat (convection) in the asthenosphere is creating this motion
The lithosphere still is moving
Earthquakes are what happen when the lithosphere moves!
