The law of superposition scientists to a. learn more about how sedimentary rock is formed. b. decipher the different types of sedimentary rock. c. determine the age of layers of rock. d. learn more about how fossils are formed.

The law of superposition helps the scientist to determine the age of layers of rock.

Further Explanation:

Superposition is the name for the observation that given a stack of layers, or beds, of sedimentary rocks, older beds are found below younger beds (as long as there has been no disturbance of the beds). Although often referred to as the law of superposition, it also is known as the principle of superposition.

The basic law of geochronology, stating that in any undisturbed sequence of rocks deposited in layers, the youngest layer is on top and the oldest on the bottom, each layer being younger than the one beneath it and older than the one above it.

The Law of Superposition makes logical sense, but in practice, it is the nature of the fossils found in the sedimentary layers that determine the relative ages of the rocks. The theory of descent with modification trumps the empirical evidence of superposition.

explanation:

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.
