Transcript Water Cycle and Clouds 2

Climatology
Goals for this Presentation
 Teach myself how to use Power Point
 To show you the amazing world of the hydraulic cycle
 To re-educate you on things you learned in intro to
Geography and have since forgotten
 I would love to make this learning experience fun and
entertaining
 Continue the trend of making fun of Al Gore.

The 3 Major Components of the
Water Cycle
Precipitation
Evaporation
Condensation
Which comes first?
Evaporation
This the first step in the water cycle. Occurs when the
water in oceans, lakes, rivers, streams, puddles,
swimming pools, or any other concentration of water is
warmed up by the Sun. The heat adds energy to
matter. This in turn causes the molecules to move
faster, bouncing off of each other, they move further
and further apart till they become gaseous. The water
then becomes, vapour.

could find on the interweb
2nd Graders’ Picture of Evaporation
Another over simplified example of
Evaporation
Condensation
Once the sun heats the water molecules to the point
where they become a vapour in the air, this warm air
then rises high into the atmosphere where
temperatures are a lot colder. The air cools down and
the vapour turns back into water. This is where clouds
are formed. Yay clouds!
Good Condensation
Bad Condensation
You best be usin a coaster under that glass!
Good Idea, Lance. Thank you.
Fog

The Humboldt
Current
 Discovered by Alexander Von
Humboldt(Prussian)
 It creates year round
upwelling in Peru. Not so
much in Chile
 Approximately 20% of the
worlds fish catch comes from
this Large Marine
Environment

Precipitation
When a large enough amount of water
droplets form 'inside' a cloud, they
become heavy enough to fall to Earth.
This is usually observed as rain, but
Precipitation can also occur as snow,
hail, sleet, etc., depending on
temperatures and humidity.
3 most common forms of
Precipitation
Snow
Rain
Hail

What happens when warm air and
cold air meet?
 When a front of cold air, which is low pressured,
moves over a front of warm air, which is high
pressured. The friction of the cold air sinking and hot
air rising creates high wind speeds and the winds
follow the path of the cold air spiraling down.
 In short a tornado may occur.

Where does all this precipitation
go?
Drainage and runoff
Drainage Patterns
Drainage Patterns
 Dentritic; basic drainage. Tributaries coming together to

form a larger river
Rectangular; this form of drainage is most common in
areas with lots of fault lines
Angular or radial; This drainage is at the peak of the
mountain or hill
Trellis; multiple small sources flow into a larger body at
almost an acute angle
Contorted; this type of drainage appears in areas where
there has been much change in the geography of the land
Parallel; many tributaries come together on a more steep
then usual downhill slope
