Water is essential for all life. Plants and animals rely on water to survive. Water is essential for all life. Plants and animals rely on water to survive. Water covers about 2/3 of the earth’s surface. Water covers about 2/3 of the earth’s surface. The way water moves around the world and the way it is stored is called the water cycle. The way water moves around the world and the way it is stored is called the water cycle. The main processes in the water cycle are; The main processes in the water cycle are; The Water Cycle SONG The Water Cycle SONG http://www.acme.com/jef/singing_science/water_cycle-160.mp3 http://www.acme.com/jef/singing_science/water_cycle-160.mp3 http://www.acme.com/jef/singing_science/water_cycle-160.mp3
3
Evaporation The conversion of liquid water into water vapour The conversion of liquid water into water vapour
4
Transpiration When moisture is lost by evaporation from plant leaves When moisture is lost by evaporation from plant leaves
5
Condensation When water vapour gets converted back into liquid water When water vapour gets converted back into liquid water
6
Precipitation When moisture falls back to earth in the form of rain, sleet, hail, snow, fog, dew and frost When moisture falls back to earth in the form of rain, sleet, hail, snow, fog, dew and frost
7
Infiltration When water seeps and moves into the soil When water seeps and moves into the soil
8
Percolation or throughflow When water moves down through the layers of soil and rock to become groundwater When water moves down through the layers of soil and rock to become groundwater
9
Surface Runoff After rain water can flow across the surface of the earth After rain water can flow across the surface of the earth
10
Groundwater: Groundwater: Water that has percolated through the soil. Water that has percolated through the soil.
11
Water moving through the soil Water running across the Earth’s surface Water stored in underground aquifers Some surface runoff evaporated the rest will infiltrate or flow down watercourses such as rivers Water evaporated from plants through the leaves Solar energy converts liquid water into water vapour to be stored as clouds Water returning to the cycle usually as rain Water stored as water vapour
