What do we call the area from the water table to the surface?
The water table sits on top of what experts call the zone of saturation, or phreatic zone. The area above the water table is called the vadose zone.
Where does the water table meet the surface?
The water table meets surface-water bodies at or near the shoreline of surface water if the surface-water body is connected to the ground-water system. In contrast to the unsaturated zone, the voids in the saturated zone are completely filled with water.
Where is the saturated zone?
zone of saturation, saturated zone) is the area in an aquifer, below the water table, in which all pores, fractures, and cavities (including karst caves) are filled with water.
What aquifer means?
An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground. There are two general types of aquifers: confined and unconfined.
What is it called when water comes out of the ground?
The underground water coming out naturally is called spring.. Springs are formed when water pressure causes a flow of water onto the surface of the earth through the cracks and tunnels within the aquifer.
What is water that flows over Earth’s surface?
The water that flows across Earth's surface is called runoff.
What is a groundwater zone?
Above the water table lies the unsaturated zone. Here the spaces in the rock and soil contain both air and water. Water in this zone is called soil moisture. The entire region below the water table is called the saturated zone, and water in this saturated zone is called groundwater.
What is called water table?
The water table is an underground boundary between the soil surface and the area where groundwater saturates spaces between sediments and cracks in rock. Water pressure and atmospheric pressure are equal at this boundary.
Where does groundwater flow to?
Water moves underground downward and sideways, in great quantities, due to gravity and pressure. Eventually it emerges back to the land surface, into rivers, and into the oceans to keep the water cycle going.
Is an aquifer?
An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground. There are two general types of aquifers: confined and unconfined.
What is the called from which water flows receive water?
Streamflow, or channel runoff, is the flow of water in streams and other channels, and is a major element of the water cycle. It is one component of the movement of water from the land to waterbodies, the other component being surface runoff.
What is groundwater water table?
The water table is an underground boundary between the soil surface and the area where groundwater saturates spaces between sediments and cracks in rock.
What are the zone of water table?
The water table is the boundary between the unsaturated zone and the saturated zone underground. Below the water table, groundwater fills any spaces between sediments and within rock.
What is underground water flow called?
Groundwater Basics Water evaporates from the oceans, condenses into clouds and then falls on the land surface as rain, only to flow into rivers and back into the sea. However, there is one aspect of the water cycle that is often forgotten – groundwater.
What is underground water called?
Groundwater is water that exists underground in saturated zones beneath the land surface. The upper surface of the saturated zone is called the water table. Contrary to popular belief, groundwater does not form underground rivers.
What is a water table aquifer?
A water table–or unconfined–aquifer is an aquifer whose upper water surface (water table) is at atmospheric pressure, and thus is able to rise and fall.
What zone is above the water table?
unsaturated zone The soil surface above the water table is called the unsaturated zone, where both oxygen and water fill the spaces between sediments. The unsaturated zone is also called the zone of aeration due to the presence of oxygen in the soil.
What are the three zones of the water table?
Water beneath the surface can essentially be divided into three zones: 1) the soil water zone, or vadose zone, 2) an intermediate zone, or capillary fringe, and 3) the ground water, or saturated zone.
What is the flow of water from the ground surface into the ground?
groundwater flow The groundwater slowly moves through the spaces and cracks between the soil particles on its journey to lower elevations. This movement of water underground is called groundwater flow.
What is the process of water flowing under the earth’s surface?
Earth's water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth.
What is another word for aquifer?

What is surface water flow?
Surface water flow is simply the continuous movement of water in runoff or open channels. This flow is often quantified as discharge, defined as the rate of flow or the volume of water. that passes through a channel cross section in a specific period of time.
What is the water surface called?
There are three types of surface water: perennial, ephemeral, and man-made. Perennial, or permanent, surface water persists throughout the year and is replenished with groundwater when there is little precipitation. Ephemeral, or semi-permanent, surface water exists for only part of the year.
What is the movement of water from Earth’s surface into the air and back again called?
the hydrologic cycle The water cycle, also known as the hydrologic cycle, describes the continuous movement of water as it makes a circuit from the oceans to the atmosphere to the Earth and on again.
What is groundwater and runoff?
Groundwater runoff means that part of the groundwater that is discharged into a stream or as a spring or seepage water.
What is called hydrosphere?
A hydrosphere is the total amount of water on a planet. The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers.
How does water move from Earth’s surface to the atmosphere?
Water at the Earth's surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.
What is water that flows across Earth’s surface?
runoff The water that flows across Earth's surface is called runoff. Eventually, runoff can enter bodies of water. Some rainwater and water from streams seeps down into the ground, collecting in spaces between rock particles. Water found in the spaces between rock particles below Earth's surface is called groundwater.
What is in mesosphere?
Most meteors vaporize in the mesosphere. Some material from meteors lingers in the mesosphere, causing this layer to have a relatively high concentration of iron and other metal atoms.
What is in the lithosphere?
The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
