What two factors determine how easily water can move through the ground?

What two factors determine how easily water can move through the ground?

Water moving below ground depends on the permeability (how easy or difficult it is for water to move) and on the porosity (the amount of open space in the material) of the subsurface rock.

Which two factors determine how easily water is able to move through rock or sediment?

The two factors that determine how easily water can move through rock or sediment are the slope of the water table and the permeability of the rock or sediment.

How do underground water moves?

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.

Does water move easily through permeable materials?

As water soaks down through permeable rock and soil, it eventually reaches layers of material that it cannot pass through. These materials have few or no spaces or cracks. Clay and granite are impermeable, meaning that water cannot pass through.

What materials can water pass through?

Almost all materials are permeable. For example, water can pass through dense materials such as clay.

What happens to water as it trickles through the material underground?

What happens to water in the ground when it reaches impermeable materials? The water stays there and forms a water table, like when you dig down in sand and reach water. Water underground trickles down between preamble materials; such as particles of soil a through cracks and spaces in layers of rock.

Why is groundwater so clean?

Unlike surface water collected in rivers and lakes, groundwater is often clean and ready to drink. This is because the soil actually filters the water. The soil can hold onto pollutants—such as living organisms, harmful chemicals and minerals—and only let the clean water through.

Is water found below the surface of the earth usually stored in aquifers?

Groundwater is water found below the surface of the Earth, usually stored in aquifers. An Aquifer is an underground layer of sand, gravel, or rock that holds water.

What objects allow humans to access groundwater select 3?

The objects that allow humans to access ground water are:

  • A spring.
  • a well drilled into an aquifer.
  • a well drilled below the water table.

What objects allow humans to groundwater?

spring well driller

What most likely caused the water to rise and erupt from the vent?

What most likely caused the water to rise and erupt from the vent? The water was heated by magma or hot rocks.

How do rivers become larger as they travel across land?

How do rivers become larger as they travel across land? Tributaries combine, adding water to rivers.

Which freshwater source is a permanent shallow?


How do rivers become larger?

Rivers start as very small streams and gradually get bigger as more and more water is added. Heavy rains and spring meltwater add so much water to some rivers that they overflow their banks and flood the surrounding landscape. Rivers grow bigger when tributaries (smaller streams) join the main river.

Which correctly lists three places that fresh water is found?

Weegy: Rivers, wetlands, lakes correctly lists the three major locations of liquid freshwater on Earth in order, from greatest amount of water to least amount of water.

Which correctly lists the three main ocean zones?

open ocean, deep, continental.

Which correctly lists three properties that are used to identify minerals?

luster, weight, streak.

What are three water sources that contribute to a river system?

Which correctly lists three water sources that contribute to a river system? Groundwater, ponds, streams Lakes, rivers, watersheds Streams, lakes, oceans.

Is River water groundwater?

Groundwater is a common source for single homes and small towns, and rivers and lakes are the usual sources for large cities. Although approximately 98 percent of liquid fresh water exists as groundwater, much of it occurs very deep.

How does water flow in and around a river?

A river forms from water moving from a higher elevation to a lower elevation, all due to gravity. When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas. Rivers eventually end up flowing into the oceans.

How does groundwater get to a river?

What I mean is, groundwater contributes to streams in most physiographic and climatic settings to a certain degree; some of the water flowing in rivers comes from seepage of groundwater into the streambed. The water flowing in rivers still originates from precipitation, but it is not all from surface runoff.

How do you know if there is water underground?

The ground penetrating radar (GPR) system is used for underground water detection. GPR is a promising technology to detect and identify aquifer water or nonmetallic mines.

How deep do you have to dig to find water?

Drilling a Water Well for household use will usually range from about 100 feet to 500 feet deep, but… When drilling a new well for your home or business, the depth of the well depends on the geology and underground water levels of the area.

What are the factors influencing the storage and movement of groundwater?

Topography and geology are the dominant factors controlling groundwater flow. Storativity describes the property of an aquifer to store water. Hydraulic conductivity is measured by performing a pumping test, i.e. by pumping one well and observing the changes in hydraulic head in neighboring wells.

Which factors influence the movement of water through soil?

There are mainly two soil conditions that affect the water vapour movement namely moisture regimes and thermal regimes. In addition to these, the various other factors which influence the moisture and thermal regimes of the soil like organic matter, vegetative cover, soil colour etc.

Which factors affect the movement of ocean water?

characteristics like temperature, salinity, density and the external forces like of the sun, moon and the winds influence the movement of ocean water. The horizontal and vertical motions are common in ocean water bodies.

What causes groundwater to flow?

Groundwater is transported through aquifers because of two main reasons: gravity and pressure. In unconfined aquifers, which we concentrate on because they are more likely to be contaminated, water always flows from high points to low points because of gravity.

What controls the direction of groundwater flow?

In basins where extensive pumping of groundwater is occurring, groundwater flow directions may be primarily controlled by pumping wells. In lowland areas near surface water bodies, ground-water flow directions may fluctuate in response to changes in surface water levels.

What is the difference between Throughflow and groundwater flow?

Water usually enters the surface sediments as precipitation. This water then percolates into the soil layer. Some of this water flows horizontally as throughflow. Water continuing to flow downward eventually reaches a permanent store of water known as the groundwater.
