Using WATER ON EARTH.

WATER ON EARTH.

How much water is exactly the Planet?.

Where is this water?.

How do you move through the Earth?

"Rivers, streams? All these are names that give the water flowing on the surface of the earth.

The streams are the smallest of the three streams are the medium and the largest rivers.

What is a river?

A river is flowing surface water on the land of a higher altitude to a lower altitude due to gravity.

Where does the water?.

The river water does not all come from surface runoff.

The rain that falls to the ground and is filtered groundwater.

At a certain depth below the surface layer is the water table, soil becomes waterlogged.

The aquifer, the ground beneath the water table is saturated while the upper soil is not. The first layer is usually moist, but not completely saturated.

Where is the water on earth?

Water is always moving around, through and on Earth in the form of vapor, liquid water and ice.

rain.

Rain and snow are important parts of the water cycle, which is vital for life that exists in the world.

The rain is essential if the water is in the heavens down to Earth, where filled with lakes and rivers, recharge groundwater and provide water for plants and animals.

rain runoff.

When rain or snow falls to the ground, not deposited there only but begins to move downward following the laws of gravity.

Some of this precipitation seeps into the ground replenishing aquifers.

Most of this water runs to lower levels

Meteorological factors affecting runoff.

• Type of precipitation (rain, snow, sleet, etc.)..

• Intensity of rain.

• Amount of rain.

• Duration of the rain.

• Distribution of rainfall over the drainage basin.

air temperature, wind, relative humidity and
stations


physical characteristics affecting runoff.

• Land use



• Vegetation • Soil type

• Drainage Area

• Form of the basin



• Elevation • Decline



• Topography • Ponds, lakes, reservoirs, watersheds, that prevent or alter the runoff downstream.

• Runoff from agricultural land (and even our backyards) can cause excess chemicals such as nitrogen and phosphorus into rivers, lakes and aquifers. These chemicals in excess can damage the water quality in the surface and the groundwater.
