Answer:
True
Step-by-step explanation:
Poorly sorted sediments tend to have lower porosity than well-sorted sediments. This statement is true. Porosity refers to the amount of empty space, or voids, within a material, such as sediments. Sediments can be sorted based on the uniformity of their grain sizes. Well-sorted sediments have particles that are similar in size, resulting in a higher porosity because the particles can pack together more efficiently, leaving more empty space between them. On the other hand, poorly sorted sediments have a wide range of particle sizes, which leads to a lower porosity because the particles cannot fit together as closely. To understand this concept, imagine filling a container with marbles of different sizes. If the marbles are all the same size, they will fit together tightly, leaving fewer gaps between them and resulting in a higher porosity. However, if the marbles are of various sizes, they will not fit together as snugly, leaving more gaps and decreasing the overall porosity. Therefore, because poorly sorted sediments have a wider range of particle sizes, they tend to have lower porosity compared to well-sorted sediments.
