What are terms related to groundwater?
Plant roots can capture the moisture passing through this zone, but it cannot provide water for wells. Also known as the unsaturated zone or vadose zone. Aquifer. An underground geological formation of sand, soil, gravel and rock able to store and yield water. Artesian Aquifer.

What is the geological process of groundwater?
Hydrogeologists and geologists are now actively exploring the role of groundwater and other subsurface fluids in such fundamental geologic processes as crustal heat transfer, ore deposition, hydrocarbon migration, earthquakes, tectonic deformation, diagenesis, and metamorphism.
What is the definition of groundwater in the water cycle?
Groundwater is the water beneath the surface of the ground in the zone of saturation where every pore space between rock and soil particles is saturated with water. Water percolates (moves downward) through this zone until it reaches the zone of saturation. The water table is the top of the saturated zone.
What is the term for a layer of water under a layer of rock?
An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt). The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.
What is the term given to underground geological formations that collect and attract water?
a geologic formation that will yield water to a well in sufficient quantities to make the production of water from this formation feasible for beneficial use; permeable layers of underground rock or sand that hold or transmit groundwater below the water table.
What is the difference between wetland and groundwater?
Some freshwater wetlands are located at points where surface water enters an underground aquifer, thereby recharging groundwater supplies. Wetlands are more often points of groundwater discharge to the surface of the land, such as springs.
What are some characteristics of groundwater?
Groundwater is the largest reservoir of liquid fresh water on Earth and is found in aquifers, porous rock and sediment with water in between. Water is attracted to the soil particles and capillary action, which describes how water moves through a porous media, moves water from wet soil to dry areas.
What are the components of groundwater?
Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, permafrost (frozen soil), immobile water in very low permeability bedrock, and deep geothermal or oil formation water.
What is water table in geology?
water table, also called groundwater table, upper level of an underground surface in which the soil or rocks are permanently saturated with water. The water table separates the groundwater zone that lies below it from the capillary fringe, or zone of aeration, that lies above it.
What features are produced by the geological work of groundwater?
Groundwater erodes rock beneath the ground surface, especially carbonate rock. Groundwater deposits material in caves to create stalactites, stalagmites, and columns.
What are three ways in which groundwater is used?
The top layer of groundwater is known as the water table and it marks the permanent zone of saturation. Three appropriate ways for preserving groundwater are: – Recycling groundwater for use. -Regulating the amount of groundwater used to water neighbourhood lawns. -Monitoring the chemicals used in fossil fuel extraction.
What is groundwater and how does it get polluted?
Groundwater becomes polluted when toxins or pollutants are emitted into the ground, or surface water that then leeches through soil and enters the groundwater.
What are some facts about groundwater?
Groundwater Facts. Groundwater is the water that fills cracks and other openings in beds of rocks and sand. Each drop of rain that soaks into the soils moves downward to the water table, which is the water level in the groundwater reservoir. Groundwater does not normally occur in underground streams, lakes, or veins.
What do you need to know about groundwater?
What is Groundwater? In simplest terms, groundwater is the water present beneath the Earth’s surface. Where is Groundwater found? Aquifers filled with groundwater are all over the planet. How is Groundwater found? How is Groundwater collected? What is Groundwater used for? Can Groundwater be dangerous? Is Groundwater Valuable?
