Which is the most negative environmental consequences of building dams for hydroelectric power Quizizz?

Which is the most negative environmental consequence of building dams for hydroelectric power Quizizz?

The dam destroys habitats by creating reservoirs of water that flood lands upstream of the dam.

Which of the following is an unintended environmental consequence of the use of hydroelectric dams?

Which of the following is an unintended consequence of the use of hydroelectric dams for electricity generation? … There will be more erosion than sediment deposition downstream from the hydroelectric dam. The population of fish that migrate to areas upstream from the hydroelectric dam to breed will increase.

What is a major disadvantage of wood harvesting Quizizz?

Which is a major disadvantage of wood harvesting and deforestation? It can lead to soil erosion and surface disruption.

Which environmental consequence is most often associated with obtaining energy from fossil fuels?

All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.

Which is the most negative environmental consequence of building dams for hydroelectric power?

Flooding land for a hydroelectric reservoir has an extreme environmental impact: it destroys forest, wildlife habitat, agricultural land, and scenic lands. In many instances, such as the Three Gorges Dam in China, entire communities have also had to be relocated to make way for reservoirs [3].

Which of the following negative consequences is most often associated with using biomass?

Which could most likely release a high dose of radiation to the environment? Biomass creates harmful emission of carbon and sulfur, and causes massive cutting of trees.

What is one negative environmental consequence of removing a dam from a river?

Short term impacts of the dam removal itself can include increased water turbidity and sediment buildup downstream from releasing large amounts of sediment from the reservoir, and water quality impacts from sudden releases of water and changes in temperature.

What might be an unintended consequence of building a dam?

The study is published in Nature Sustainability. Building dams and reservoirs is one of the most common approaches to cope with drought and water shortage. … Their paper shows that increasing reservoir storage capacity can also lead to unintended effects in the long term, and, paradoxically, worsen water shortage.

Which of the following is a negative environmental impact of using solar photovoltaic energy?

The potential environmental impacts associated with solar power—land use and habitat loss, water use, and the use of hazardous materials in manufacturing—can vary greatly depending on the technology, which includes two broad categories: photovoltaic (PV) solar cells or concentrating solar thermal plants (CSP).

How the destruction of forests affects atmospheric levels of carbon?

Destruction of forests affects the levels of atmospheric carbon in two ways. With less trees pulling carbon dioxide from the atmosphere during the process of photosynthesis, atmospheric levels of carbon will increase. … They emit more carbon than they take in.

Which would most likely be included in an environmental impact statement concerning drilling for oil in Antarctica?

An environmental impact statement describes the possible effects a project might have on the environment. Which would most likely be included in an environmental impact statement concerning drilling for oil in Antarctica? Greenhouse gases are often produced as a result of obtaining and using fossil fuels.

Which of the following statements best describes the most unsustainable method of clear-cutting forests to harvest timber?

Which of the following statements best describes the most unsustainable method of clear-cutting forests to harvest timber? All of the trees in a forest are cut down and removed in one operation. Industrial logging threatens many forested ecosystems.

Which energy source causes the most damage to the environment?

Coal produces more pollution than any other energy source. While coal produces just 44% of U.S. electricity, it accounts for 80% of power plant carbon emissions. Burning coal leads to soot, smog, acid rain, global warming, and carbon emissions.
