What else can I help you with?
What bodies of water did people build dams across to form reservoirs?
over rivers
How is hydroelectric power an indirect form of solar energy?
Because solar energy runs the water cycle, giving rise to precipitation, and then the rain water flows into the reservoirs of dams.
What are pumped storage reservoirs?
The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
What type of land form is closely associated with hydroelectric power?
A river valley, with adequate flow, and sufficient gradient, and a sufficiently large surface area of water storage; these are the needs for an hydroelectric power station. Sometimes, the water from one water catchment may be led via a tunnel to a discharge site which offers an overall better fall.
Are dams streams ponds lakes glaciers ice sheets oceans and reservoirs bodies of water?
If you use your dictionary, you can learn lots of things - like the fact that a dam is something that is build across a body of water that blocks the flow of the water. Everything else on the list is some form of water.
Do dams need water?
of course not ! dams need water as the energy to create electricity. Basically water is fuel to create electricity in dams and without it, it is impossible if there isn't any other form of fuel energy provided to dams ...
In what form is excess energy stored?
Excess energy is typically stored in the form of chemical energy in batteries, potential energy in elevated water reservoirs for hydroelectric power, or as heat in thermal energy storage systems.
What form of energy is uses the water from dams?
Mechanical energy
What forces threaten salmon populations?
Many forces threaten salmon populations, there are forces such as over fishing, fishing techniques (purse seine), dams that block the upstream travel of salmon, reservoirs and lakes behind dams, damage from logging in the form of disturbed soil, and mining damage.
What happens when the water table is above the surface at various places?
If the water table is higher the the surface of the land, water will seep out of the land surface and form a puddle, pool or lake. The depth of the water body will increase until the water surface is at the same level as the surrounding water table - this is a state of equilibrium. If the water table lowers, so will the water level in the water body, until equilibrium is reached. Water moves slowly into and out of the land surface and follows the movement of the water table in the area. Don't confuse this with storage reservoirs behind dams. These have an artificially high water level and the surrounding water table can be lower than the reservoir.
What are Ireland's main water sources?
From nature, in the form of rain, springs, wells, rivers and lakes with some of these being put into reservoirs.
Why is the sun considered the primary source of energy for hydroelectricity?
The sun's energy drives the water cycle by evaporating water from bodies of water, which then condenses to form clouds and falls back to the Earth as precipitation. This precipitation accumulates in reservoirs behind hydroelectric dams. When the water flows through the dam, it drives turbines to generate electricity. Thus, the sun's energy indirectly powers hydroelectricity by creating the water that ultimately provides the kinetic energy needed for electricity generation.
