Transcript of Water Cycle

Transpiration: Plants put water back into the air. Condensation: Water cools and form liquid clouds.
(the change of water from its gaseous form
(water vapor) into liquid water.) Precipitation: When liquid water falls to earth. Run-off: when water flows down hills into the ocean. Infiltration: rainwater soaks into the ground
and becomes groundwater What is the sun's role in the water cycle? Water Cycle Water is always moving
through our environment.
It moves through the air,
through plants and
through the earth.
This continuous movement
is called the water cycle. Huang Bin Young Jun Valentini ex: rainwater evaporating from warm pavement after a thunderstorm. ex:when a glass of ice water "sweats" when you bring it
outside in the summer. ex:Rain, snow, sleet, hail, and other forms of water that
comes from the sky. ex:rain runs off the land and drains
into rivers, lakes and streams. Evaporation When the sun warms water from lakes, ponds, or the ocean and turns it into water vapor Evaporation Condensation Precipitation Transpiration Run-off Infiltration ex:When the sun shines on plants,
tiny drops of water are released into the air permeability is the ability of a material to allow fluids,
such as water to pass through it. Larger particles will
increase permeability, because pore space is larger,
that there will be more water flows down. permeability precipitation Run-off great amount greater
river Run-off can occur when the rate of precipitation exceeds
the permeability rate. The greater the run-off, the greater
amount of discharge of river. The slope of the surface is too great to allow
infiltration;on a gentle slope, there is more
infiltration. The steeper the slope, the greater the run-off;
on a gentle slope, is less run-off Porosity is a measure of how much
of a rock is open space.The greater
the porosity, the greater the amount
of infiltration that can occur . The Sun's heat provides energy to evaporate water from the Earth's surface.
