What is gravity dam?
A gravity dam is a solid structure, made of concrete or masonry, constructed across a river to create a reservoir on its upstream. The section of the gravity dam is approximately triangular in shape, with its apex at its top and maximum width at bottom. The section is so proportioned that it resists the various forces acting on it by its own weight. Most of the gravity dams are solid, so that no bending stress is introduced at any point and hence, they are sometimes known as solid gravity dams
Hydroelectric dams use the kinetic energy of water to produce electrical energy What is the environmental drawback of building hydroelectric dams?
One environmental drawback of building hydroelectric dams is the disruption of river ecosystems, including changes in water flow, sediment transport, and fish migration patterns. Dams can also lead to reduced water quality downstream and the displacement of communities and wildlife due to flooding of land for reservoirs.
How is gravity useful?
Gravity is a force that keeps things from floating in mid air. Without it you would have been out of the earth by now!! Gravity is a strength deep under the earth (from the inside). Hope this was useful..
What are two ways energy can be stored?
Electrical energy can be stored in batteries. Water energy can be stored behind dams.
What is the uses gravitational energy in your daily life?
Gravitational energy is used in various ways in daily life, such as generating hydroelectric power through water dams, allowing objects to fall to the ground and generate kinetic energy, and enabling us to walk or climb stairs by overcoming the force of gravity. Additionally, gravitational energy plays a role in keeping celestial bodies in orbit around each other in the universe.
What are the materials used in building a gravity dam?
There are many gravity dams constructed of compacted earth. High dams are generally concrete. All dams require a spillway to be safe. The spillway must be armored.
What are the Differences between gravity dams and earth dams?
Gravity dams:It is made up of masonry or solid concreteIt can be constructed to any heightLess maintenanceEarth dams:It is made up of soil and gravelIt can be constructed to moderate heightIt is cheaper
Are masonry dams also called as gravity dams?
no
What are constructed to control the flow of river water?
Dams

What are the purpose of PA DAMS?
The purpose of the dams that are found in the state of PA are to prevent water from entering another water source or landform. Dams are often manmade, but can be constructed by animals like beavers.
What are the relative advantages and disadvantages of the gravity dams over earth dams?
Advantage of a gravity dam is that every section will be stable and reliable. An Earth dam can overflow and collapse because of erosion.
Where are the gravity dams in India?
India has several notable gravity dams, primarily located in the states of Himachal Pradesh, Uttarakhand, and Maharashtra. Prominent examples include the Bhakra Dam in Himachal Pradesh, the Tehri Dam in Uttarakhand, and the Koyna Dam in Maharashtra. These dams are strategically built to harness river water for irrigation, power generation, and flood control. Additionally, several other gravity dams can be found throughout the country's river systems, contributing to water management and energy production.
Why dams are constructed in a safer place?
The construction of the Glen Canyon Dam formed which body of water?A. Lake Mead B. Grand River C. Canyon Lake D. Lake Powell dams are constructed in a safer place because of the following reasons:*it must not be build in earthquake occurring place.*while moving vehicles,the dam should not fall.*the dams should build very strong.*it is useful for irrigation.
How come a bridge or a dam can be built in water when water is the worst enemy of civil structures?
Bridges and dams are built after a coffer dam is constructed to reroute the water. When the structure is complete the coffer dams are removed or destroyed.
Why have humans created dams and levees?
Man Made dams are constructed for several reasons. One may construct a dam to balance water height or achieve agricultural irrigation.
