Quickly... this is a harder one, because all of possible answers are the result of interactions over a long time. However, these change the surface of the earth the fastest
1.) Volcanoes
2.) Flooding 
Over a long time
1.) Through the rock cycle... earthquakes, mountain forming, etc.

Answer:
Cytokinesis
Explanation:
All living cells undergo division, it is the method employed in duplicating themselves. The division of cells involves two major processes viz; karyokinesis and cytokinesis. 
Karyokinensis involves the division of the genetic material (DNA) in the nucleus. The chromosomes are initially separated into opposite poles/ends inside the cell. After which the cytoplasm of the whole cell then separates resulting in two daughter cells each having its own genetic material. This process is called CYTOKINESIS.
Although CYTOKINESIS occurs in all eukarotes and prokaryotes, the way it occurs in the eukaryotic plant and animal cells differ in the sense that, in animals, it occurs with the formation of a cleavage furrow as a result of pinching inward of the cell membrane until the two daughter cells form while in plants, a cell plate is formed at the cell's centre and a new membrabe and cell wall is formed around each cell plate.
