What factors determine how easily water can move through underground materials?
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.
What is the ability of a material to allow water to pass through?
permeability–the ability of a material to allow the passage of a liquid, such as water through rocks. Permeable materials, such as gravel and sand, allow water to move quickly through them, whereas impermeable material, such as clay, don’t allow water to flow freely.
What term best describes how easily water moves through the soil?
Permeability describes how easily water can flow through the rock or unconsolidated sediment and how easy it will be to extract the water for our purposes.
When a material lets water flow through it we describe that as being?
Terms in this set (11) Materials that allow water to easily pass through, or permeate, are called permeable. Materials that water cannot pass through easily are called impermeable.
What are the two characteristics affect the presence and movement of ground water?
The rate of groundwater flow is controlled by two properties of the rock: porosity and permeability.
How easily water can move through an aquifer is called?
The size of the spaces determines how easily water moves through rock and soil. If the spaces are connected, this too affects water movement. Because they have large and connected spaces, materials such as sand and gravel allow water to pass through, or permeate. They are thus known as permeable materials.
Does water move easily through impermeable materials?
it moves through the pores between particles of soil and rock. Water moves easily through permeable materials, but does not move easily through impermeable materials.
What are the three ways that water moves through a soil?
Movement of water into soil is called infiltration, and the downward movement of water within the soil is called percolation, permeability or hydraulic conductivity. Spaces in soil, between the mineral and organic matter, that are filled with water or air.
What are the two features of a good aquifer?
Aquifers must be both permeable and porous and include such rock types as sandstone, conglomerate, fractured limestone and unconsolidated sand and gravel.
What determines groundwater flow?
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.
What are the factors affecting the movement of 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. The horizontal motion refers to the ocean currents and waves.
