Explanation:
A. Erosion of rock
D. Sediments are distributed by river to a new location
B. Particles settle out and form layers
E. Fossils form as living things are trapped in the layers
C. Humans analyze formations to determine the age of rock
The steps given are keys which ensures we understand how sediments form sequentially in basin of deposition. Coupled with this, we are shown a peep into the world of fossilization.
