What is
PRECIPITATION?

The Answer……or answerS

Precipation

All the forms!

●Rain

●Snow

●Sleet

●Hail

Rain

- moisture condensed from the
atmosphere that falls visibly in
separate drops.

Snow

- atmospheric water vapor
frozen into ice crystals and
falling in light white flakes or
lying on the ground as a white
layer.

Sleet

- atmospheric water vapor
frozen into ice crystals and
falling in light white flakes or
lying on the ground as a white
layer.

Hail

- atmospheric water vapor
frozen into ice crystals and
falling in light white flakes or
lying on the ground as a white
layer.

Weather Measurement

1.

An Anemometer is used to measure
WIND SPEED.

2. A Rain Gauge is used to measure
rainfall.

Weather Measurement

3. A windsock is used to measure WIND
DIRECTION.

4. A weather vane is also used to measure
WIND DIRECTION

Meteorologist

- Scientist who studies weather phenomena

Hypothesis

Mountains can
affect weather.

I think mountains can affect weather
because…

The air itself overcomes the mountaintop
easily, but the clouds get “heavier” (more
“soaked” with water) while getting higher
and mostly do not overcome the
mountaintop. So the rain stays mainly on
the windward side of the ridge, whereas
the leeward side is in so called
“precipitation shadow”.

Variables that may affect the
outcome...

●Temperature

●Humidity (the amount of water in the
air)

Hypothesis support

Geographical
structures like
mountains and
valleys can
affect where
precipitation
falls.
