This is a picture of glacier scars found in Africa. What are these evidence for?
Africa has always been near the equator
Africa was once in an area of the Earth that had a very cold climate
The continents have not moved
sea floor spreading
What does the theory of continental drift state?
The continents were once joined in a super-continent and have moved over time
Continents are stationary and do not move
The Earth is broken into lithospheric plates that move due to convection currents
none of the above

What would be the most likely way this coastline would change over time?
A fire could destroy the vegetation
The waves could erode the beach
The beach would grow due to deposition
