How do you explain a dam to a child?
A dam is a structure built across a stream or river to hold water back. Dams can be used to store water, control flooding, and generate electricity.
Whats is a dam?
A dam is a large wall or barrier that blocks or stops the flow of water, forming a reservoir or a lake. Most dams have a section called a spillway or weir over which, or through which, water flows, either sometimes or always.
What is dam simple words?
A conventional dam holds water in a man-made lake, or reservoir, behind it. When water is released through the dam, it spins a turbine connected to a generator that produces electricity. The water returns to the river on the downstream side of the dam.
What is a dam explanation for kids?
A dam is a large wall or barrier that blocks or stops the flow of water, forming a reservoir or a lake. Most dams have a section called a spillway or weir over which, or through which, water flows, either sometimes or always.
How do you describe a dam?
A dam is defined as a barrier or structure across a stream, river or waterway to confine and then control the flow of water. Dams vary in size from small earth embankments, often for farm use, to high massive concrete structures generally used for water supply, hydropower and irrigation.
How do dams work simple?
A conventional dam holds water in a man-made lake, or reservoir, behind it. When water is released through the dam, it spins a turbine connected to a generator that produces electricity. The water returns to the river on the downstream side of the dam.
What is a dam and its purpose?
A dam is a structure built across a stream or river to hold water back. Dams can be used to store water, control flooding, and generate electricity.
What is a dam simple definition?
A dam is a large wall or barrier that blocks or stops the flow of water, forming a reservoir or a lake. Most dams have a section called a spillway or weir over which, or through which, water flows, either sometimes or always.
What is a dam explained for kids?
Dams are huge man-made structures that act as barriers on a river. Today, the main reason people build dams is to produce electricity. They are also built to restrict and control the flow of water in a river. Throughout history, dams have been used to prevent flooding and to irrigate (water) farmland.
What is a dam Class 5?
A dam is a barrier across flowing water which hamper, directs or reduces the flow of water. Dams and reservoirs can be effectively used to control floods by regulating river water flows downstream the dam.
What is a dam for kindergarten?
A dam is a large wall or barrier that blocks or stops the flow of water, forming a reservoir or a lake. Most dams have a section called a spillway or weir over which, or through which, water flows, either sometimes or always.
What is a dam easy definition?
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions.
What is the structure of a dam?
The water retaining structure is the walled structure of the dam, which resists the water and allows a controlled quantity to flow downstream. The side of the wall or dump which faces the down-stream is called the face of the dam. The plane top surface of the dam is called the crest of the dam.
How does a dam make electricity for kids?
Dams are huge man-made structures that act as barriers on a river. Today, the main reason people build dams is to produce electricity. They are also built to restrict and control the flow of water in a river. Throughout history, dams have been used to prevent flooding and to irrigate (water) farmland.
What are the three purposes of dams?
Dams are important because they provide water for domestic, industry and irrigation purposes. Dams often also provide hydroelectric power production and river navigation. Domestic use includes everyday activities such as water for drinking, cooking, bathing, washing, and lawn and garden watering.
What is a dam in simple words?
A dam is a large wall or barrier that blocks or stops the flow of water, forming a reservoir or a lake. Most dams have a section called a spillway or weir over which, or through which, water flows, either sometimes or always.
What is a dam Grade 2?
A dam is a large wall or barrier that blocks or stops the flow of water, forming a reservoir or a lake. Most dams have a section called a spillway or weir over which, or through which, water flows, either sometimes or always.
What is a dam in science?
Dams are huge man-made structures that act as barriers on a river. Today, the main reason people build dams is to produce electricity. They are also built to restrict and control the flow of water in a river. Throughout history, dams have been used to prevent flooding and to irrigate (water) farmland.
What is dam in sentence?
A dam, whether it is big or small, is a structure that holds back water. It is a barrier built across a stream or river to stop or redirect the flow of water.This causes water to pool behind the jam of sticks and mud and results in a new pond being built. Humans have been building dams for thousands of years.
What a dam is and what they do?
A dam is a large wall or barrier that blocks or stops the flow of water, forming a reservoir or a lake. Most dams have a section called a spillway or weir over which, or through which, water flows, either sometimes or always.
What is a dam Kids definition?
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability.
What is a dam Class 7?
A dam is a barrier that blocks flowing water or sends it in a new direction. People and animals build dams to control rivers and to create ponds or lakes.
How is a dam constructed?
The dam is raised in steps of about 600 mm. The edges are formed first, by making low concrete walls on the upstream and downstream faces of the dam. Concrete is then transported to the area between the walls and spread in a thin layer using bulldozers. Rollers are then driven over the concrete to compact it down.
What are the main features of the dam?
Basic Features A dam blocks the flow of water in a river or stream so that it must pass over, through, or around the barrier. On the upstream side, the water backs up into an artificial lake, or reservoir, for storage. Water may pass over the crest of the dam itself or near the dam in chutes, tunnels, or shafts.
How do dams produce electricity?
The dam stores lots of water behind it in the reservoir. Gravity causes it to fall through the penstock inside the dam. At the end of the penstock there is a turbine propellor, which is turned by the moving water. The shaft from the turbine goes up into the generator, which produces the power.
