This is also called the water cycle It is the recycling of the water between the oceans, land and atmosphere There are 6 main parts to the water or hydrologic cycle.
Solar Radiation- the sun, the source of energy need for the water cycle Condensation –is the process by which water transitions from a gas (or vapor) phase into a liquid phase ( cloud) Precipitation- returns water to the Earth in the form of snow, rain, sleet, hail Evaporation- returns water to the atmosphere in the form a gas Transpiration- is the evaporation of water from vegetation Water storage- place on the earth that water is stored until it is re-evaporated into the atmosphere (lakes, oceans, ice caps) Infiltration- is water soaking into the ground Runoff- water flowing along the surface of the earth
The Earth has a LIMITED supply of water Once we harm the water bad enough we are not able to use it. Approximately 70-75% of the Earth is covered with water ( salt). The amount of water that seeps into the ground or runs-along the surface is influenced by: Climate Slope Soil type Rock type Vegetation Land use and degree of saturation
Run- off occurs when: The ground is saturated The slope is too great It is to cold, the ground if frozen When there has been a lot of rain
Ground water is water that is found below the ground Ground water is filtered as it moved through the rock and soil.
Zone of Aeration -upper soil layers that hold both air and water.. Zone of saturation- layer of soil below the water table where the ground is saturated with water Water table- The level below which the ground is saturated with water. Impermeable layer- a layer of solid material, such as rock or clay, which does not allow water to pass through..-
Choose either the picture of the water cycle or the groundwater zone On pasteboard draw a picture of what you have chosen. Label and define each of the important parts
