Fresh Waters

Term Definition
Water Cycle The continuous movement of water from the ocean to the atmosphere to land and back to the ocean.
Evaporation Takes place when water from the oceans and the Eartha??s surface changes into water vapor. Energy from the sun causes evaporation. Water gains energy during evaporation.
Condensation Takes place when water vapor cools and changes into water droplets that form clouds in the atmosphere. Water loses energy during condensation.
Precipitation Is rain, snow, sleet, or hail that falls from clouds onto the Eartha??s land and oceans.
Runoff Is precipitation that flows over land into streams and rivers. This water later enters oceans.
Percolation Is the downward movement of water through pores and other spaces in soil due to gravity.
Groundwater The water located within the rocks below the Eartha??s surface is called groundwater.
Water Table The continuous movement of water from the ocean to the atmosphere to the land and back to the ocean.
Aquifer A body of rock or sediment that stores groundwater and allows the flow of groundwater.
Porosity The percentage of the total volume of a rock or sediment that consists of open spaces.
Permeability

Impermeable A rock that stops the flow of water is impermeable.
Artesian Spring A spring whose water flows from a crack in the cap rock over the aquifer.
Well
A human – made hole that is deeper than the level of the water table is called a well.
