Unconformities are when new sediment is placed atop an eroded piece of rock. The three unconformities are disconformity, angular unconformity, and nonconformity.
Answer:
D. A layer of pale, sandy soil lacking clay and iron
Explanation:
The soil is complex, composed of multiple layers/horizons all of which have different characteristic that make every horizon to have its own special role in it. The horizon E is the third horizon from the top. This horizon is characterized by being mostly sandy, and because the water manages to go through it very easily it is a horizon in which there's heavy leaching going on. Because of the leaching, this horizon loses the clay, iron, and aluminium from it, thus they accumulate in the horizon below it. As a horizon it is very important, especially for the trees, as their root systems manage to develop very well in this horizon because it is loos and sandy.

Option A cannot be true since a scientific hypothesis must be testable, otherwise it is not scientific.
Option C is incorrect as well as scientific knowledge DOES need peer review and verification before the results are accepted by the scientific community.
Option D is also false as science is always changing and adapting. What this means is that conclusions or understandings can be changed if new evidence surfaces that suggests otherwise.
Therefore, the only correct answer is B) Explanations are based on observations, evidence, and testing.
This is true as we cannot make statements or explanations in science without first conducting tests, making observations and gathering evidence to support our claims.
