Question

the cross sections of the crust below represent two areas of sedimentary rock layers. these layers show how the earths surface has changed over time. which statement provides evidence that earths surface has changed over time? the sedimentary rock layers________. a. consist of several layers and have been folded and split b. consist of several layers and are flattened c. have combined to form one layer d. contain fossils

Explanation:

Sedimentary rock layers that are folded and split show that forces (such as tectonic activity) have acted on them over time, changing their original flat - lying state. Flattened layers (Option B) just show a common state of sedimentary rocks when first deposited. Combining to form one layer (Option C) is not a typical indication of surface change over time as sedimentary rocks usually form in layers. While fossils (Option D) can show past life forms, the question is about evidence of surface change. Folding and splitting of layers (Option A) directly show that the Earth's surface (where these rocks are part of the crust) has been deformed over time.

Answer:

A. consist of several layers and have been folded and split
