Which geologic term or phrase explains why the reason rock layers typically form parallel to each other? Cross-cutting relationships Original horizontality Superposition Unconformities

Answer:

Original Horizontality Principle is the Relative Chronology Principle which states that sediments are always deposited in horizontal layers. Any geological phenomenon that changes the horizontality is always after sedimentation.

Explanation:

Answer:

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)

the gypsy moth is a pest species whose larvae feed on the leaves of hardwood trees. the population size of gypsy moths naturally changes in cycles. as a result, the amount of defoliation caused by the moths also fluctuates. which statement describes how the change in size of the gypsy moth population from 1972 to 1981 most likely affected the ecosystems represented by the maps?​

Plants that live in hot, dry climates have evolved mechanisms to help conserve limited water supplies. One example is the closing of leaf openings by guard cells during the day to decrease water loss from their leaves. This detection of and response to an environmental stimulus is an example of

BIOLOGY STUDENTS CLICK MY QUESTION PLEASE

Three plants were grown to study the effects of nitrate and magnesium ion deficiency on their development. They were kept in the same conditions, except for the types of minerals supplied.
Use
Plant A was provided with all essential minerals.
Plant B was given all minerals except nitrate ions. Plant C was given all minerals except magnesium ions. State three conditions, other than water and the concentration of mineral ions, that would need to be kept the same for all the plants, in order to make the investigation a fair test
