What are the best groundwater reservoirs?
Good aquifers are those with high permeability such as poorly cemented sands, gravels, or highly fractured rock. An aquitard is a body of material with very low permeability. In general, tightly packed clays, well cemented sandstones, and igneous and metamorphic rocks lacking fractures are good aquitards.
Which of the following reservoir contains the most water?
the ocean Reservoirs. The largest water reservoir is the ocean, containing 97.3% of all water on Earth.
Which of the following would make the best aquifer?
Answer and Explanation: b) Sandstone would be the best aquifer. Sandstone is a sedimentary rock, comprised of sand-size grains of minerals and rocks, that can hold water….
What is the difference between the saturated and unsaturated zones of groundwater quizlet?
What is the difference between saturated and unsaturated zone? Unsaturated zone: The area between the soil-water belt and the water table where pore spaces are not saturated with water. Saturated zone: The zone of rock below and including the water table where pore spaces are completely filled with water.
What is groundwater reservoir?
Artificial underground reservoirs (sometimes named groundwater reservoir/underground reservoirs) are a water storage, supply, and regulation system that makes use of a natural aquifer as a water storage space.
Which of the following reservoirs contains the most water Mcq?
Water reservoirs
- Oceans. By far the largest reservoir is the ocean, which contains 96% of the Earth's water and occupies more than two-thirds of the Earth's surface. …
- Glaciers. Freshwater makes up only about 4% of the Earth's water. …
- Groundwater.
What is the greatest reservoir of freshwater in the world?
glaciers About three-quarters of Earth's freshwater is stored in glaciers. Therefore, glacier ice is the second largest reservoir of water on Earth and the largest reservoir of freshwater on Earth!
Which of the following reservoirs of the water cycle is the largest?
the oceans The largest reservoir by far is the oceans, which hold about 97% of Earth's water.
Which of the following would make the best aquifer highest porosity and permeability?
Gravel and sand are both porous and permeable, making them good aquifer materials. Gravel has the highest permeability.
Which of the following would likely make the best aquifer quizlet?
Good aquifers include sandstone, conglomerate, well-jointed limestone, bodies of sand and gravel, and some fragmental or fractured volcanic rocks such as columnar basalt.
What is the difference between the saturated and the unsaturated zones of groundwater?
Groundwater is found in two zones. 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.
Which material would consistently make the best aquifer?
Gravel makes a good aquifer because it is extremely permeable and porous. The large pieces of sediment create significant pore spaces that water can travel through. Often, gravel must be surrounded by a less permeable soil type, such as rich clay or impenetrable rock.
What should be the main characteristics of a good underground reservoir?
Underground reservoirs are geological structures that have unique features. There is a porous medium having some degree of permeability. The porosity allows natural gas to be contained within the medium. The permeability allows the gas to move from point to point within the medium.
Which of the following is the main source of groundwater?
rainwater Explanation: The rainwater and water from other sources such as rivers and ponds seeps through the soil and fills the empty spaces and cracks deep below the ground. The process of seeping water into the ground is called infiltration. The groundwater thus gets recharged by this process.
What is the greatest reservoir of fresh water in the world?
glaciers About three-quarters of Earth's freshwater is stored in glaciers. Therefore, glacier ice is the second largest reservoir of water on Earth and the largest reservoir of freshwater on Earth!
What is the largest groundwater source in the world?
The world's most overstressed groundwater source, according to researchers, is the Arabian Aquifer System, which supplies water for more than 60 million people. Researchers used readings from NASA's two GRACE satellites, which measure variations in the earth's gravitational pull, Famiglietti told The Huffington Post.
Which of the following is the largest reservoir within the hydrologic cycle Mcq?
The oceans are the largest reservoir within the hydrologic cycle.
Is sand layers the best aquifer?
Unconsolidated materials like gravel, sand, and even silt make relatively good aquifers, as do rocks like sandstone. Other rocks can be good aquifers if they are well fractured.
Does shale make a good aquifer?
Good water wells may be localized only in certain areas of limestone formations. Sandstones generally have good porosity and permeability, making a good well. Shales have poorer permeability and well yields are poorer.
Which type of rock would make the best aquifer?
Sandstone Sandstone: Fine-grained rocks such as sandstone make good aquifers. They can hold water like a sponge, and with their tiny pores, they are good at filtering surface pollutants.

What is the greatest use of groundwater?
Groundwater supplies drinking water for 51% of the total U.S. population and 99% of the rural population. Groundwater helps grow our food. 64% of groundwater is used for irrigation to grow crops. Groundwater is an important component in many industrial processes.
Which rock type would make the best aquifer quizlet?
Good aquifers include sandstone, conglomerate, well-jointed limestone, bodies of sand and gravel, and some fragmental or fractured volcanic rocks such as columnar basalt.
What are the attributes of a good reservoir?
In the study area, a reservoir is considered to be effective when its permeability is greater than μm2, porosity is greater than 5%, and the gas saturation is greater than 50%.
What are the 2 main sources of groundwater?
It is found from following sources:
- (i) Meteoric Water: This is the main source of groundwater. …
- (ii) Connate Water: Water contained in pores and cavities of sedimentary rocks under seas and lakes is called connate water. …
- (iii) Magmatic Water:
What are the three types of groundwater?
What are the types of underground water sources? Infiltration galleries, infiltration wells, springs, and wells are the different types of underground water sources.
What is the largest reservoir of water on Earth quizlet?
Oceans are the largest reservoir on earth.
What is the main source of underground water?
precipitation Most groundwater originates as meteoric water from precipitation in the form of rain or snow. If it is not lost by evaporation, transpiration or to stream runoff, water from these sources may infiltrate into the ground.
Which of the following is the largest reservoir with in the hydrological cycle?
the oceans The largest reservoir by far is the oceans, which hold about 97% of Earth's water. The remaining 3% is the freshwater so important to our survival, but about 78% of that is stored in ice in Antarctica and Greenland.
