Can someone help me fill in the boxes?

Card B:

This shows that the South American Plate and the African Plate are moving. This can possibly help future predictions for earthquakes and where they will be.

Card C:

Volcanic activity can be linked to seismic activity (possibly earthquake activity). This shows that the South American Plate and the African Plate are moving and releasing magma, causing volcanoes to fill up and possibly erupt.

Card D:

This can help us tremendously about tracking the movement of plates. When we track movements of plates, it can help us know where and when earthquakes might happen. This can help the safety of the people around the possibly earthquake areas.
