Which is defined as the subsurface area in which all pore spaces are completely fill with water?
Infiltration. The subsurface in which all pore Spaces are completely filled with water. The zone of saturation. The portion of stream flow that consists of groundwater. Base flow.
Which zone has all of the spaces within and between the rocks filled with water?
Groundwater: Groundwater is the water present in the spaces in the soil and rocks of Earth's crust and the size of these pores varies in size. The Groundwater table is classified into different zones on the basis of the distribution of water within the soil.
Which is defined as the downslope Unchannelized flow of water across the surface?
The downslope, unchannelized flow of water across the surface is known as. overland flow.
What occurs when precipitation soaks into the subsurface?
Infiltration is the process by which precipitation or water soaks into subsurface soils and moves into rocks through cracks and pore spaces.
What is subsurface water?
groundwater, water that occurs below the surface of Earth, where it occupies all or part of the void spaces in soils or geologic strata. It is also called subsurface water to distinguish it from surface water, which is found in large bodies like the oceans or lakes or which flows overland in streams.
What is saturated zone of groundwater?
The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone. The top of the saturated zone is called the water table (Diagram 1). The water table may be just below or hundreds of feet below the land surface.
What is the name given to the region under ground where pore spaces are filled with air?
Rain that falls on the surface seeps down through the soil and into a zone called the zone of aeration or unsaturated zone (also called the vadose zone), where most of the pore spaces are filled with air.
What is saturation zone?
The soil or rock located below the top of the groundwater table. By definition, the zone of saturation is saturated with water. Also see water table. Where raw wastewater is exfiltrating from a sewer pipe, the area of soil that is moistened around the leak point is often called the zone of saturation.
Which of the following is defined as the line of contact between the zone of aeration and the zone of saturation?
water deficits in summer months. The line of contact between zone of aeration and the zone of saturation is known as the. water table.
Which condition may exist in confined aquifers where the water is under pressure quizlet?
In some confined aquifers the water is under pressure, creating an artesian well where water may rise to the surface without pumping. The flow or volume of water in a channel.
What is condensation and precipitation?
Definitions. condensation:transition from vapor phase to liquid phase. precipitation: deposition of liquid water droplets and ice particles that are formed in the atmosphere and grow to a sufficient size so that they are returned to the Earth's surface by gravitational settling.
What is infiltration of water?
Infiltration is defined as the flow of water from aboveground into the subsurface. The topic of infiltration has received a great deal of attention because of its importance to topics as widely ranging as irrigation, contaminant transport, groundwater recharge, and ecosystem viability.
What are the types of subsurface water?
What are the types of underground water sources? Infiltration galleries, infiltration wells, springs, and wells are the different types of underground water sources.
Which of the following is a subsurface source of water?
Groundwater Option B: Groundwater is the water present below the surface of earth also known as a subsurface water source, Groundwater is filled by seeping of water from surface water sources.
What is the aerated zone?
ZONE OF AERATION: The area of an unconfined aquifer above the water table where the pore spaces among soil particles and rock formations are filled with air.
Where is the unsaturated zone?
The unsaturated zone, immediately below the land surface, contains water and air in the open spaces, or pores. The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone.
What do we call the area of an aquifer where the soil pores are filled with air not water?
unsaturated zone Rain that falls on the surface seeps down through the soil and into a zone called the zone of aeration or unsaturated zone (also called the vadose zone), where most of the pore spaces are filled with air.
What is a groundwater aquifer?
An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells. 5 – 8. Earth Science, Geology, Social Studies.
What is saturated zone and unsaturated zone?
The unsaturated zone, immediately below the land surface, contains water and air in the open spaces, or pores. The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone. The top of the saturated zone is called the water table (Diagram 1).
Which is the saturated zone?
The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone. The top of the saturated zone is called the water table (Diagram 1). The water table may be just below or hundreds of feet below the land surface.
What is perched groundwater?
Perched groundwater is unconfined groundwater separated from an underlying body of groundwater by an unsaturated zone. It occurs when subsurface water percolating downward is held by a bed or lens of low-permeability material.
Which condition may exist in confined aquifers where the water is under pressure?
In some confined aquifers the water is under pressure creating an artesian well where water may rise to the surface without pumping.
Why is the water in some aquifers such as the High Plains Aquifer called fossil water?
Why is the water in some aquifers such as the High Plains Aquifer called "fossil water"? Some aquifiers recharge very slowly. What is a place where water naturally flows out of the ground? What usually makes groundwater flow in a normal zone of saturation?
What is water condensation?
Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
What is evaporation and condensation?
Condensation is the change from a vapor to a condensed state (solid or liquid). Evaporation is the change of a liquid to a gas.
What is water percolation?
Percolation is the movement of water through the soil itself. Finally, as the water percolates into the deeper layers of the soil, it reaches ground water, which is water below the surface. The upper surface of this underground water is called the "water table".
What is infiltration and aquifer?
Infiltration: The process of seeping rainwater and water from other sources into the ground to form groundwater is called infiltration. Infiltration refills the groundwater. Aquifer: Rainwater and water from rivers, ponds seep through the soil and fill the gaps between particles of soil and rocks.
What is sub surface drainage system?
Subsurface drainage is the removal of water from the rootzone. It is accomplished by deep open drains or buried pipe drains. i. Deep open drains. The excess water from the rootzone flows into the open drains (see Fig.
What are the different forms of subsurface water?
Infiltration galleries, infiltration wells, springs, and wells are the different types of underground water sources.
Where is the saturated zone?
The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone. The top of the saturated zone is called the water table (Diagram 1). The water table may be just below or hundreds of feet below the land surface.
