The line at which two tectonic plates meet
What type of boundary forms a mid-ocean ridge?
Divergent
What happens at a convergent boundary
The two plates move toward each other and one is pushed under the other into the mantle
What is a plate
You are given a prompt about the reason Mesosaurus fossils were found on two separate continents
Which of the following is a good (full points) claim:
A. I am not sure but probably earthquakes
B. Earthquakes and volcanoes are because of plate movement.
C. Mesosaurus fossils were found on two separate continents because the two continents lie of either side of a divergent boundary.
C. Mesosaurus fossils were found on two separate continents because the two continents lie of either side of a divergent boundary.
Complete sentences. Uses vocabulary words. Specific
Define convergent
Plates that come together
What type of boundary forms mountains and trenches?
Convergent boundary
What happens at a divergent boundary
The two plates move apart from each other and the mantle bubbles up to form new rock
Draw a diagram of divergent plates. Be sure to label with arrows which direction the plates are moving. Label the landforms created here. Label where rock is being added/destroyed

You are given a prompt about the reason Mesosaurus fossils were found on two separate continents
Which of the following is good (full points) evidence:
A. As we saw in class, divergent boundaries move away from each other and form new land in the gap.
B. The maps in class showed divergent boundaries and lines and stuff
C. Because of what we learned in class
A. As we saw in class, divergent boundaries move away from each other and form new land in the gap.
Complete sentences. Specific. Clear.
Define divergent
Plates that move apart
What landforms are created at transformational boundaries
None!
What happens at a transformational boundary
The two plates move alongside each other (up and down) but do not push in or away
Draw a diagram of convergent plates. Be sure to label with arrows which direction the plates are moving. Label the landforms created here. Label where rock is being added/destroyed

You are given a prompt about the reason Mesosaurus fossils were found on two separate continents
Which of the following is good (full points) reasoning:
A. Therefore, my evidence is right
B. Therefore, the fossils could be on different continents now but were once joined together. Over time, the divergent boundary between them pushed them apart but the fossils remaining in the ground and moved with the continents.
C. Because we see earthquakes and stuff there too.
B. Therefore, the fossils could be on different continents now but were once joined together. Over time, the divergent boundary between them pushed them apart but the fossils remaining in the ground and moved with the continents.
Clear. Connects evidence to the claim. Explanatory. Complete sentences
What is the difference between the crust and the mantle?
The crust is the outer layer (rock, water, soil, continents) that floats on top of the mantle. The mantle is the second layer of Earth made of magma
What boundary types can create volcanoes?
What causes earthquakes?
Friction from plate movement
What does the mantle do at:
A. Convergent boundaries
AND
B. Divergent boundaries
At convergent boundaries, the mantle destroys the plate that is pushed into it
At divergent boundaries, magma from the mantle bubbles up to form new rock along the edges of the plates
What are 3 way to improve this CER about Mesosaurus fossils?
I think that Mesosaurus fossils are on two separate continents now because of plate movement. In class we learned about the plates moving and they moved so now they are on 2 different continents
1. More specific evidence
2. Expanded reasoning
3. Use your vocabulary words to help get your point across (this is vague)
How are volcanoes formed at convergent boundaries
What causes plates to move?
Convection currents in the mantle. The magma under the crust flowing up as it heats and back down as it cools
In 500 million years, why would it take longer to fly from New York to Egypt over the Atlantic Ocean?
Because of the divergent boundary in the middle, in 500 million years the Atlantic Ocean will be wider and the distance between North America and Africa will increase (when trying to fly this direction). Therefore, it will take longer because you are flying a greater distance
Write a CER for this prompt: Why are Mesosaurus fossils now found on 2 separate continents?
Vocab words: divergent, convergent, mantle, mid ocean ridge, millions of years, plate movement
