Question: explain three ways that a river reshapes earth’s land surface. be sure to explain how erosion, weathering, or deposition of rock or soil contribute to the change.

Erosion

Weathering

Deposition

Explanation:

Erosion is the natural part of the rock. Sediments will not be there without erosion or the sedimentary rock. Therefore erosion is the picking of the unconsolidated soil as well as sediments. Most rivers erode to transport the sediments. The sediments in other places deposit the sediment in different locations. The principles agent behind the eroding bedrocks and sediments is the moving water.

The dissolving and worn of the rock is called weathering. Weathering occurred in different processes such as mechanical, organic and chemical processes.

answer; (d) melting of sea ice;

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.
