What is formed by the action of underground water?
Sinkholes and caves are erosional landforms formed due to the action of ground water.
What are results of overuse of groundwater?
When groundwater is overused, the lakes, streams, and rivers connected to groundwater can also have their supply diminished. Excessive pumping in coastal areas can cause saltwater to move inland and upward, resulting in saltwater contamination of the water supply.
What are three results of aquifer depletion?
Some of the negative effects of groundwater depletion:
- drying up of wells.
- reduction of water in streams and lakes.
- deterioration of water quality.
- increased pumping costs.
- land subsidence.
What are the effects of groundwater?
Effects of Groundwater Depletion
- Groundwater depletion will force us to pump water from deeper within the Earth.
- Large bodies of water will become more shallow from groundwater depletion.
- Saltwater contamination can occur.
- As large aquifers are depleted, food supply and people will suffer.
What is the result of groundwater deposition?
Groundwater dissolves minerals, carries the ions in solution, and then deposits them. Groundwater erodes rock beneath the ground surface, especially carbonate rock. Groundwater deposits material in caves to create stalactites, stalagmites, and columns.
What type of landforms can be formed by groundwater?
Groundwater erodes rock beneath the ground surface, especially carbonate rock. Groundwater deposits material in caves to create stalactites, stalagmites, and columns.
What are the effects of water depletion?
EFFECTS OF WATER DEPLETION Deep wells : as a result of water depletion, deep wells need to be dug because of the water shortage. Pumps will have to be put deeper and deeper to extract water. Expensive resource : water being a renewable resource, it will become very expensive due to limited availability.
What are the environmental impact of groundwater uses?
The extreme use of groundwater resources can have serious concerns, such as uplifting and seismic activities, ecological environment deterioration, land subsidence, vegetation degradation, livelihoods for rural poor, and food security implications.
What are the causes and effects of groundwater contamination?
Groundwater is one of the most important sources of water for irrigation. But, groundwater is susceptible to pollutants. Groundwater contamination occurs when man-made products such as gasoline, oil, road salts, and chemicals get into the groundwater and cause it to become unsafe and unfit for human use.
How does groundwater cause karst topography?
If the ground water that flows through the underlying permeable bedrock is acidic and the bedrock is soluble, a distinctive type of topography, karst topography, can be created. Movement of solution along fractures and joints etches the bedrock and leaves limestone blocks as isolated spires or pinnacles.
Which of the following features is the work of underground water?
Explanation: Topographical features formed by underground water can be seen particularly, This distinctive topography formed due to the action of underground These beautiful forms are called stalactites.
Which landform listed is mainly formed because of erosion by groundwater?
Caves. Caves are one of the types of landforms created by groundwater erosion. Working slowly over many years, groundwater travels along small cracks. The water dissolves and carries away the solid rock.
What is the geological action of the ground water?
The geological action of the ground water involves processes like erosion, transportation and deposition. As we know, ground water circulates slowly under the influence of gravity, in general, following the slopes of the water-table.
What is the rate of water movement in underground?
As we know, ground water circulates slowly under the influence of gravity, in general, following the slopes of the water-table. The rate of water movement is very slow and vary considerably from one place to another according to the permeability of the rocks. Mechanical processes of erosion are absolutely insignificant in case of underground water.
How is a losing stream connected to the ground water system?
Losing streams can be connected to the ground-water system by a continuous saturated zone (Figure 9A) or can be disconnected from the ground-water system by an unsaturated zone. Where the stream is disconnected from the ground-water system by an unsaturated zone]
What are the mechanical processes of erosion in underground water?
Mechanical processes of erosion are absolutely insignificant in case of underground water. Ground water brings about erosion mainly through chemical processes i.e. by the solution action, which is particularly effective in regions of soluble rocks like limestone, dolomite, gypsum and anhydrite, rocksalt etc.
