Newer layers of earth form <u>on</u><u> </u><u>top</u> of older layers, so as we dig, we can see further back in time. Comparing the fossils between the layers can offer evidence of change.

Answer: Newer layers of earth form on top of older layers, so as we dig, we can see further back in time. Comparing the fossils between the layers can offer evidence of change. Phyletic gradualism slow, but constant gradual change; supported by transitional species in the fossil record Punctuated equilibrium long periods of no change followed by short periods of rapid change. Can also be supported by the fossil record when no transitional species are found. hope this helps p :) but, i just looked up the sentences and it gave me the answers.
two molecules or moieties combine to form one single molecule, together with the loss of a small molecule. When this small molecule is water, it is known as a dehydration reaction; other possible small molecules lost are hydrogen chloride, methanol, or acetic acid.
