Question

Quizplus · Accepted Answer

A layer of gravel with sediment grains that do not fit together tightly will likely exhibit high permeability, meaning water can easily move through the sediment. Karst landscape is a type of landscape formed from the dissolution of soluble rocks, such as limestone, and is not related to the sediment grain size or packing. Secondary porosity refers to the creation of additional pore space after the rock has formed, which is not related to the sediment grain size or packing. A perched water table occurs when an impermeable layer of rock or sediment lies above the main water table, creating a localized zone of saturation. The permeability of the gravel layer would not necessarily determine whether or not there is a perched water table.
