Dynamic Planet/Earth's Fresh Water

=Earths Fresh Water= Earths Fresh water is centered on Rivers Lakes and Groundwater.

Hydrological Cycle
There is a common steady Cycle of water through out the earth the best way

to know it is to follow the Image Below. http://www.solcomhouse.com/images/usgs_water_cycle.jpg

More Info
The water cycle is composed of 16 major steps. The easyest place to start is the oceans. The sun which imparts energy in

the form of heat to the water causes evaporation of water vapor into the

air. Once the vapor is in the air through Evaporation, Sublimation(solid

directly to gas), or Transpiration(plants release vapor) it rises ad

condenses into clouds. Clouds grow and release water as precipitation

Precipitation can fall as Snow and accumulate in ice caps or glaciers or

melt and flow overland which is termed Snow melt. it can also fall as Rain

and flow as surface runoff or infiltrate into to ground and become

groundwater where in turn it can replenish aquifers. Eventually it will

reenter the ocean or water cycle.

Stream Drainage
Streams follow a general pattern based on topography. Drainage Channels

form where runoff can cutts into the ground.

Dendritic Drainage
Dendritic Drainage is the most common and looks similar to a tree.

Dendritic Drainage occurs where a region is above a single type of

bedrock (homogeneous). Which gives the entire area a similar resistance to

erosion and therefore a seemingly random placement of tributaries. Most

tributaries will join a larger stream at an acute angle.

Parallel Drainage
Parallel Drainage generally form where there is a large hill.They develop

in areas with parallel regions of rock that are harder to erode.

Trellis Drainage
Trellis Drainage Patterns form where there is a folded topography like the

Appalachian mountains. tributaries enter the main Stream at near right

angles.
