Water Cycle
Weather
The water cycle and weather
Water is necessary to all life on Earth.
Every part of the water cycle influences
Weather. The water cycle controls the
Distribution of water on earth and in the
atmosphere. Clouds and precipitation
Are evidence of water moving through
The water cycle.
The water cycle and climate
The water cycle also shapes climates around the world.
Precipitation or water in that falls from the clouds is one of
the ways people classify climate .The average precipitation
In a region tells us what type of climate it . The water cycle
creates reservoirs to store water . The Ocean is a good
example .

Vocabulary
Air Masses-a large
body of air with only
small horizontal
variations of
temperature, air
pressure and moisture.
Front-the interface
between air masses of
different temperatures
or densities .

Changes in the
weather happen as
different air masses
move through a
region. Something
you may not realize
is that fronts not only
extend in the
horizontal direction
but in the vertical as
well.
Warm fronts and Cold fronts
Warm front

A warm front is the
transition zone where a
warm air mass is replacing
a warmer air mass . On a
weather map a warm front
is represented by a solid
line with triangles point to
the warmer air.


Cold Front
Is the transition where a
cold air mass is
replacing a warmer air
mass. On a weather map
a cold front is
represented by a solid
line with semi-circles.

Weather Map
Temperature
Temperature tells us if the air is warm or cold.
Density is the amount of matter in an object. The
density of the air depends of it temperature.
Temperature is influenced by cloud cover.
AIR PRESSURE
Air pressure is the weight of the air above the
Earth's surface.
High pressure occurs when the air pressure is
greater than the surrounding area. High pressure
usually means dry weather and cooler
temperatures. Low pressure occurs when the air
pressure is lower than surrounding areas. Low
pressure usually means wet weather and warmer
weather.

Wind
Clouds
Clouds are water droplets or ice crystals in the air .
They play a major role in weather. They have an
influence in the temperature and bring different
types of precipitation . The four different types of
precipitation are rain,snow,sleet and hail . Clouds
commonly form at frontal boundaries and around
areas of low pressure .Clouds also block radiation
form the Sun. This influences temperatures.
Types of precipitation
Precipitation
Precipitation is a solid or liquid water that falls from a cloud to
the surface of the earth. Precipitation is likely when two different
air masses meet at a frontal boundary. High humidity also increases
chance of precipitation .
Weather data builds
climate records
Weather builds climate
records
Scientists need a lot of data to predict weather. Trends are patterns
in weather . They show consistent changes in the weather . This makes
forecasting easier. Trends in weather tell us about climate. A climate
Record is a historical record of weather data for a specific region.
