PLEASE HELP, WILL MARK BRAINLEST TO WHO EVER ANSWERS FIRST Which geologic term or phrase explains why the reason rock layers typically form parallel to each other? Cross-cutting relationships Original horizontality Superposition Unconformities

Original Horizontally

Explanation:

First of all, the principle of original horizontality explains why sediments form horizontal and parallel layers. Rocks broken down by weathering are distributed according to how they retain the least energy.

2. Scientists use the term "unconformity" to refer to a place in a body of rock where rock is missing. Unconformities lead geologists to hypothesize about past events, but they may not be able to find conclusive proof for their hypotheses. Some types of rock weather more quickly than others, further complicating the analysis of rock layers.

3. According to the Law of Superposition, the bottom layer is generally the oldest layer of rock. Therefore, fossils found in the lower strata are older in relation to fossils found in higher rock layers.

4. Picture Below (at the end it mentions cross-cutting relationships)

Have a wonderful day!!

they dont have any evidence
