rills
Backwatres is any river or flowing water turned back from its regular path due to an obstruction - either man-made( dams ) or natural ( a forest, a land piece)
The earliest humans to reference the ground called it earth (in their languages, of course). Over time, this has spread to reference the entire planet, rather than just the ground in one spot. Other popular names include Terra Firma and Gaia.
it is made out of water and bark from trees
Salt water is obtained by dissolving sodium chloride in water.
3% of the world is made of fresh water
Hydroelectricity.
stones and fast flowing water can block the water from flowing
On the INSIDE of the barrel, they are called grooves. Together with the ungrooved areas, called lands, they make up rifling. On the OUTSIDE of the barrel, they are called flutes. These are cuts made in the barrel to make it lighter.
The process by which water is continually made available is called the water cycle. This cycle involves the evaporation of water from bodies of water, condensation into clouds, precipitation as rain or snow, and then the water flowing back into lakes, rivers, and oceans, completing the cycle.
rill: A tiny groove in the soil made by flowing water.
It is called a rill. Rills are small channels that form on a hillside when water flow concentrates in a particular path, leading to soil erosion.
hydroelectric
The energy made by moving water is called hydroelectric energy. It is generated by converting the kinetic energy of flowing water into electricity using turbines connected to generators. This renewable energy source is commonly harnessed in hydroelectric power plants.
a tiny groove in soil made by flowing water
All grooves are made at the same time with a tool called a "button" that is pushed or pulled down the barrel
If you mean canyon, such as the Grand Canyon, they are made by erosion. Water flowing through them cuts into the earth and washes it away.
Hydro-electric energy can be created in many ways, but all forms of energy require the spinning of a turbine to generate electricity.
