Answer:
a
Explanation:
planting vegetation barriers
Alfred Wegener produced evidence in 1912 that the continents are in motion, but because he could not explain what forces could move them, geologists rejected his ideas. Almost 50 years later Harry Hess confirmed Wegener’s ideas by using the evidence of seafloor spreading to explain what moved continents.
Answer:
Divergent plate boundary
Explanation:
The African continent, the second largest in the world, is splitting in two parts. The African plate on which the African continent lies is actually after heavy geologic activity which causes it to split in two parts that are moving in opposite directions. This is a prime example of a divergent plate boundary. As the African plate gradually separates into the Nubian and Somali plates, they will open up a gap between them that will constantly grow. That gap will fill in with the ocean waters, splitting the two land masses with a natural barrier, as well as giving rise to a new sea, or maybe even an ocean over the course of millions of years.
