A mid-ocean ridge landform is found along the plate boundary between the South American Plate and African Plate.

# data[].attributes.body
Earthquakes occur in a pattern along the plate boundary between the South American Plate and African Plate.

# data[].attributes.body
The South American Plate and African Plate moved apart gradually at a divergent plate boundary.

# data[].attributes.body
The continents of South America and Africa, where Mesosaurus fossils are located, are currently about 4,000 km apart and separated by the Atlantic Ocean. GPS measurements show that the South American Plate and African Plate are currently spreading apart from each other at a rate of 3.0 cm per year.

Reasoning Statement

# data[].attributes.body
This evidence supports claim ___ because…

This matters because...

This means...

All of this suggests that….. because…

# data[].attributes.body
The earthquakes along the plate boundary between the South American Plate and African plate tell us that the plates are moving. As plates move earthquakes happen.

# data[].attributes.body
Earthquakes occur when plates move at plate boundaries. If there are earthquakes at the plate boundary between the South American and African plate, then there must be movement at the plate boundary.

Mid ocean forms are only found by a divergent boundary. It shows that 3 cm per year is not a long distance but then lover time it will end up moving a long way. This means that its a divergent because its gradually moving over time.

# data[].attributes.body
Mid ocean ridges are only found in divergent plate boundaries.

# data[].attributes.body
We know that the Plate boundary between South American and African is a divergent plate boundary because we know that divergent plate pulls apart .

# data[].attributes.body
Mid-ocean boundary's only happen in divergent boundaries. So this information shows that a divergent boundary cold of caused the African and South American plate to separate by pushing the two plates apart from each other.

# data[].attributes.body
Evidence card B shows that the plate boundary between the South American plate and the African plate was a divergent plate boundary. I know this because it says that a mid-ocean ridge was created and they are only found at divergent plate boundaries.

# data[].attributes.body
This evidence supports the claim because Mid ocean ridges are only found when there is a divergent boundary happening.When there is a divergent boundary the plates are separating away and once the separate away the magma from the ocean floor will come out that create Basalt rock,so it also create's lava and earthquakes happening.

# data[].attributes.body
Evidence card B shows that the plate boundary between south america plate and African plate show that fossiles and that Mid ocean ridges happened when a divergent plate boundary when the plates move.

# data[].attributes.body
Evidence  card B  shows  that  mid ocean-ridge shows that south american plate and African plate was formed by a divergent plate

# data[].attributes.body
A mid-ocean-ridge can only be formed by a divergent plate boundary. There is a mid-ocean-ridge where the plate boundaries are at. Also the only way a plate can move away is if it a divergent plate.

# data[].attributes.body
Evidence Card B supports the claim because if there is a mid-ocean ridge then there will be a divergent plate boundary because divergent plate boundaries make up mid-ocean ridges.

# data[].attributes.body
Evidence card B supports _ because mid ocean ridges mean that there are divergent

# data[].attributes.body
This evidence card shows that there is a mid ocean ridge, and mid ocean ridges are formed by divergent boundaries

# data[].attributes.body
This evidence card shows that the evidence that it is

# data[].attributes.body
This evidence card shows evidence that it is divergence because of the ocean ridge

# data[].attributes.body
Gradually means that it happened very slowly and a divergent plate is when two plates spread apart from each other like a mid-ocean ridge.

# data[].attributes.body
This shows that there is a divergent boundary moving the two plates apart. The plates move very slow. Only 3 cm a year is not that fast. It would take millions of years to move apart. So it would have to move apart over time

# data[].attributes.body
Evidence Card D supports the claim that the plates moved gradually because if the plates are only moving 3 cm per year then it would take a long time to move 4,000 kilometers apart, so it would've moved gradually.

# data[].attributes.body
Evidence card D supports the claim because even if it moves slowly it is still moving apart slowly.

# data[].attributes.body
This is a convergent plate boundary because it has a plate between two plates that are coming to each other.

# data[].attributes.body
The two plates are moving apart and it's divergent plate boundaries. They are moving gradually because they move 3.0 cm per year.

# data[].attributes.body
This is a divergent plate boundary because the plates are spreading apart from each other, and its moving gradually because its a mid-ocean ridge.

# data[].attributes.body
The plates are moving apart slowly because it moves 3 cm each year so that can make it take a long time for it to have a far distance apart and that takes millions of years. So the South American and African plate move gradually apart.

# data[].attributes.body
This shows that when there is a divergent plate boundary moving it only moves 3.0 cm per year there for it will take a long time to move 4,000 km apart from the Atlantic ocean and the GPS measurements

# data[].attributes.body
Evidence card D  shows that the divergent plates move every  3.0 year

# data[].attributes.body
This shows if it only moves 3 cm per year it is very slow and will take a really long time to move a lot

# data[].attributes.body
Evidence card D shows that the plates move slowly because the plates only move 3 cm per year.

# data[].attributes.body
This shows that the rate are really small and they are moving slow that means the plates are moving gradually because they are at a rate of 3.0 cm per year.

# data[].attributes.body
Evidence supports the claim because the plates are still moving apart they are only moving 3.0 cm and it moved 4,00km.
