What are Lava Lines?

In the below animation, we see an artist's rendition of the pattern of geologic activity that scientists have observed in the middle of the Atlantic Ocean.
NGSS Phenomena: An animation showing a red, fiery line between the South American plate and the African plate.

1. This is an example of which of the following geological processes?

2. What evidence could scientists observe that would support the conclusion that these are underwater volcanoes?

3. Using what you know about the changing earth, explain how this phenomenon relates to plate tectonics.

4. Explain one change we can observe as a result of the process shown in this phenomenon and the time period in which we should expect to see this change.

5. What evidence would scientists need to observe in order to determine that this is a plate boundary?

6. Using what you know about the theory of Plate Tectonics, explain how this feature relates to the shapes of the continents of Africa and South America.
