Answer:
TRUE
Explanation:
Chemical weathering usually refers to the process in which the water comprising various chemicals reacts on the rocks and disintegrates them. The chemical weathering process occurs both at and below the surface of the land. At various depths, the rocks are comprised of cracks and fractures, which are filled up with water comprising the chemicals. This water reaching these joints and fractures are percolated from the surface. These chemicals comprising water start reacting with the rocks and eventually expands the cracks and joints.
For example, in the region where there is abundant carbonate rocks, these chemical comprising water (such as acid water) when enters, it reacts with the rocks and dissolves them, and thereby give rise to the formation of caves and sinkholes.
Thus, the above-given statement is true.

In some types of research the target population might be as broad as all humans, but in other types of research the target population might be a smaller group such as teenagers, pre-school children or people who misuse drugs.
It is more or less impossible to study every single person in a target population so psychologists select a sample or sub-group of the population that is likely to be representative of the target population we are interested in.
This is important because we want to generalize from the sample to target population. The more representative the sample, the more confident the researcher can be that the results can be generalized to the target population.
One of the problems that can occur when selecting a sample from a target population is sampling bias. Sampling bias refers to situations where the sample does not reflect the characteristics of the target population.
