The correct answer is - 2.1 cm per year.
In order to get to the result of how much the African plate has been moving annually over the last 100 million years, we should first turn the kilometers into centimeters:
1 m = 100 cm
1 km = 1,000 m
1,000 m = 100,000,000 cm
2,1 x 100,000,000 = 210,000,000 cm
We got to the result of 210 million cm of total movement. Now we have to divide the number of cm with the number of the years in which the plate has moved that much, which is 100 million:
210,000,000 / 100,000,000 = 2.1 cm
So we get a result of an average movement of 2.1 cm per year pf the African plate during the period of 100 million years.
Answer:
it's the regolith....hope this helps you
C Horizon - Also called regolith: the layer beneath the B Horizon and above the R Horizon. It consists of slightly broken-up bedrock. Plant roots do not penetrate into this layer; very little organic material is found in this layer. R Horizon - The unweathered rock (bedrock) layer that is beneath all the other layers.
An ocean current is a continuous movement of water in the ocean in some direction - this means that the water flows at a similar speed and direction despite the fact that it's not the same water - i.e. there is a water exchange in the current. The currents are caused by such factors as temperature and salinity of water.
