Water Resources and Management Test Review

Where is water stored in large reservoirs in the form of ice?

• Glaciers

• Groundwater

• Oceans

What is the difference between porosity and permeability?

• Porosity is the ability of a material to store water in glaciers and ice caps, while permeability is the ability of the material to store groundwater in aquifers.

• Porosity is the amount of water and air passing through a material, while permeability is the volume of empty spaces within the material.

• Porosity is the volume of empty spaces within a material, while permeability is the amount of water and air passing through the material.

Which of the following best defines water quality?

• Water quality is determined solely by its physical properties, such as temperature and clarity.

• Water quality refers solely to the chemical composition of water, such as its pH level and mineral content.

• Water quality encompasses the chemical, physical, biological, and radiological characteristics of water.
