How do dams affect the environment?

Dams store water, provide renewable energy and prevent floods. Unfortunately, they also worsen the impact of climate change. They release greenhouse gases, destroy carbon sinks in wetlands and oceans, deprive ecosystems of nutrients, destroy habitats, increase sea levels, waste water and displace poor communities.

Which of these is not a reason for water scarcity?

The correct option is D Construction of dams Population growth is a major reason for water scarcity.

What is the greatest threat to biodiversity quizlet?

human alteration of habitats poses the single greatest threat to biodiversity throughout the biosphere. – agriculture, urban development, forestry, mining, and environmental pollution have brought about massive destruction and fragmentation of habitats.

How does mining affect water resources?

Water running through mine tailings can become polluted. The acid runoff further dissolves heavy metals such as copper, lead, mercury into groundwater or surface water. The rate and degree by which acid-mine drainage proceeds can be increased by the action of certain bacteria.

How does placer mining affect the environment?

Placer mining is a way of obtaining mineral and metal resources from loose river sediments. Due to the smaller scale of placer mining, it does less damage to the surrounding environment compared to other methods of surface mining, though it can still disrupt river ecosystems with pollution and sediments.

What are point and non point sources of water pollution?

Point and Nonpoint Pollution Sources Pollution originating from a single, identifiable source, such as a discharge pipe from a factory or sewage plant, is called point-source pollution. Pollution that does not originate from a single source, or point, is called nonpoint-source pollution.

Which is the best example of a point source of water pollution?

Examples of point sources include sewage treatment plants, oil refineries, paper and pulp mills, chemical, automobile, and electronics manufacturers, and factories.

How much of the total water on the planet is fresh non frozen surface water quizlet?

Only 2.5% of Earth’s water is fresh and of that, more than two thirds is frozen.

What type of buildings and monuments are most susceptible to?

What type of buildings and monuments are most susceptible to acid damage? Limestone and marble.

What are nonpoint sources of water pollution?

Nonpoint source pollution can include: Excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. Oil, grease and toxic chemicals from urban runoff and energy production. Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks.

What are the point and nonpoint sources of water pollution?

Water pollutants come from either point sources or dispersed sources. A point source is a pipe or channel, such as those used for discharge from an industrial facility or a city sewerage system. A dispersed (or nonpoint) source is a very broad, unconfined area from which a variety of pollutants…

What are five threats to biodiversity explain what is meant by each threat?

Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.

What are major threats of biodiversity explain?

The human population requires resources to survive and grow, and many of those resources are being removed unsustainably from the environment. The three greatest proximate threats to biodiversity are habitat loss, overharvesting, and introduction of exotic species.

Why there is a problem of water scarcity mention any three reasons?

Water shortages may be caused by climate change, such as altered weather patterns including droughts or floods, increased pollution, and increased human demand and overuse of water. A water crisis is a situation where the available potable, unpolluted water within a region is less than that region’s demand.

Where is water scarcity the worst?

West Africa and North Africa As of 2015, Yemen is among the most water scarce countries in the world. The majority of Yemen’s population experiences water scarcity for at least one month during the year.

How do dams cause water pollution?

Dams alter habitat They can trap sediment, burying rock riverbeds where fish spawn. Dams that divert water for power and other uses also remove water needed for healthy in-stream ecosystems. Peaking power operations can cause dramatic changes in reservoir water levels.

How do dams affect water systems?

Dam construction and closure modify the downstream transfer of OC and essential nutrients, and thus the trophic state of the river system and that of receiving water bodies, including lakes and nearshore marine environments.

How do mines pollute water?

Water running through mine tailings can become polluted. The acid runoff further dissolves heavy metals such as copper, lead, mercury into groundwater or surface water. The rate and degree by which acid-mine drainage proceeds can be increased by the action of certain bacteria.

How mining activities affect water pollution?

The heavy metal mine water penetrates into the groundwater through surface seepage, changing the pH of the water body, affecting the self-purification ability of the water body, and causing serious pollution damage to the surrounding rivers and farmland.

How does surface mining affect water?

However, even with current regulations, surface mining can affect fish and aquatic resources through erosion and sedimentation, dewatering of wetlands, diverting and channelizing streams, and contaminating surface water and aquifers with toxic chemicals.

Which type of mining was least damaging to the environment?

Sub-Surface mining is likely the least harmful to the environment.

Which of the following is not a point source of water pollution?

(c) The non-point sources of water pollution do not have a specific location for the discharge of water pollutants into the water bodies, e.g. run-off from crop fields, logging areas, oil spills through cargo ships, etc.

What are 5 examples of point pollution?

EXAMPLES OF POINT SOURCE POLLUTIONIndustrial plants/factories (e.g., oil refineries, pulp and paper mills, chemical manufacturers, automobile manufacturers, food processors, pharmaceutical manufacturers) Pollutants: oil, thermal pollution, toxic chemicals, heavy metals, pharmaceuticals.Sewage Treatment Plants.

What is an example of water pollution?

Examples include wastewater (also called effluent) discharged legally or illegally by a manufacturer, oil refinery, or wastewater treatment facility, as well as contamination from leaking septic systems, chemical and oil spills, and illegal dumping.

Which of the following is not considered to be freshwater?

Answer: (4) Oceans Ocean water contains a lot of salts dissolved in it, so ocean water is very salty. The ocean is not a freshwater habitat.

What percent of Earth’s water is not found in a river or stream?

According to the U.S. Geological Survey, most of that three percent is inaccessible. Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water.

What types of buildings and monuments are most susceptible to damage from acid rain?

What type of buildings and monuments are most susceptible to acid damage? Limestone and marble.

What type of buildings and monuments are most susceptible to damage from acid deposition?

Acid deposition also affects human-made structures. The most notable effects occur on marble and limestone, which are common building materials found in many historic structures, monuments, and gravestones.

Which of the following are not causes of water scarcity?

C)Construction of dams and resources do not cause scarcity of water. Explanation: -> Rapid growth of uncontrolled population require food and water to survive. -> Uneven distribution of water resources can cause scarcity.

What are 8 causes of nonpoint source water pollution?

These sources can include rain and snowmelt runoff, spills, leaks, sediment erosion, soils containing fertilizers and pesticides, sewage overflows, croplands, failing septic tanks, and more.

What are some examples of point source and nonpoint source pollution?

Pollution originating from a single, identifiable source, such as a discharge pipe from a factory or sewage plant, is called point-source pollution. Pollution that does not originate from a single source, or point, is called nonpoint-source pollution.

What are problems with water scarcity?

The impacts of water scarcity affect families and their communities. Without clean, easily accessible water, they can become locked in poverty for generations. Children drop out of school and parents struggle to make a living.

What are the problems caused by water scarcity?

Water scarcity limits access to safe water for drinking and for practising basic hygiene at home, in schools and in health-care facilities. When water is scarce, sewage systems can fail and the threat of contracting diseases like cholera surges. Scarce water also becomes more expensive.

What are the 6 main threats to biodiversity?

Below, we discuss six of the major threats to biodiversity: climate change, habitat loss and degradation, pollution, invasive species, over-exploitation and epidemics.

What are the 5 major causes of biodiversity loss?

Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming.

What is nonpoint source pollution of an aquatic ecosystem?

Nonpoint source pollution refers to water pollution from diffuse sources (Wilson et al., 1986). Nonpoint source water pollution negatively influences water bodies from sources such as polluted runoff from agricultural areas draining into a river, or windborne debris blowing out to sea.

What is an example of nonpoint source pollution quizlet?

Nonpoint pollution sources are broad, diffuse areas, rather than points, from which pollutants enter bodies of water. Examples include runoff of chemicals and sediments from cropland, livestock feedlots, clear-cut forests, urban streets, parking lots, lawns, and golf courses.

What are the four main threats to biodiversity?

Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.

What effect does a dam have on the water ecology?

Dams fragment rivers & streams and convert free- flowing ecosystems into lake-like ecosystems. As a result, the native riverine species are much less abundant & diverse because they can not thrive in the altered environment.

What are the effects of dams on aquatic environment?

Dams alter aquatic ecology and river hydrology upstream and downstream, affecting water quality, quantity and breeding grounds (Helland-Hansen et al., 1995). They create novel and artificial types of aquatic environment for the life span of the dam.

What effect would the construction of dams on major river systems have on the coastal environment?

Dam construction on rivers which intercepts sediments in reservoirs is one of the causes for reduced sediment discharge into sea. Because of dams, the sediment supply to an estuary and its adjacent coast is reduced, thus accelerating coastal erosion.

How does mining affect the water table?

Mines that go beneath the water table are dewatered by pumping, which draws-down the water table in the surrounding landscape. This can reduce the water available to other users and reduce the discharge to streams and other groundwater-dependent ecosystems.

What are the effects of water pollution?

EFFECTS OF WATER POLLUTIONDestruction of biodiversity. Water pollution depletes aquatic ecosystems and triggers unbridled proliferation of phytoplankton in lakes — eutrophication —.Contamination of the food chain. Lack of potable water. Disease. Infant mortality.

Which type of mining is not a type of surface mining?

Highwall mining is another form of mining sometimes conducted to recover additional coal adjacent to a surface-mined area. The method evolved from auger mining but does not meet the definition of surface mining since it does not involve the removal of overburden to expose the coal seam.

What type of mining is the best for the environment?

In situ mining, for example, can be more environmentally friendly than underground mining and is cheaper than many mining methods. Implementing recently discovered green mining technologies.
