One cause of tsunami's is earthquakes in the ocean floor in the image which point represents the hypocenter an underwater earthquake

Point D

Explanation:

The hypocenter of an earthquake is usually defined as the point from which an earthquake originates. It is also known as the focus of an earthquake.

In the given image, the plates share a type of plate boundary, where the plate moves along the fault line. Due to this movement, the rocks are adversely affected, and it tries to adjust along this region, as a result of which, a certain amount of energy is released. This energy is propagated towards the surface of the earth, affecting the water body, generating large waves which are commonly known as tsunami.

Thus, in the image above, the hypocenter (focus) of the underwater earthquake is point D which lies on the fault line.

Thus, the correct answer is Point D.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
