Red and blue show plate motion at both divergent and convergent boundaries, just

Question

Red and blue show plate motion at both divergent and convergent boundaries, just at different points in time.

2.    What must happen in order for an ocean basin to begin getting smaller?
   
   Mountains must form
   A convergent boundary must form.
   A divergent boundary must form

It stops diverging and turns into permanent seafloor.

it gets subducted

Only a large ocean

1. What do the red and blue arrows indicate? Red shows plate motion at convergent boundaries, and blue shows plate motion at divergent boundaries. Red shows plate motion at divergent boundaries, and blue shows plate motion at convergent boundaries.

Red and blue show plate motion at both divergent and convergent boundaries, just at different points in time.

2.    What must happen in order for an ocean basin to begin getting smaller?
   
   Mountains must form
   A convergent boundary must form.
   A divergent boundary must form

3. What happens to the divergent plate boundary between Stage 4 and Stage 5?
It becomes a sedimentary accretionary wedge.

It stops diverging and turns into permanent seafloor.

it gets subducted

4. If the supercontinent Pangaea was at Stage 7, when there was one major continent and one large ocean, what was present before Pangaea? Earth formed with Pangaea already existing Both smaller continents and large oceans, depending on how far in the past Several smaller continents with no oceans

Only a large ocean

5. How do tectonic plates change over time? They can divide into separate plates. They neither divide nor combine. They can combine with other plates. They can both divide and combine.
