Rain
• Water vapor accumulates in the
clouds, forming drops that fall onto the
earths surface
•When precipitation falls from the sky,
its liquid state is known as rain.
• Rain can happen at any time during
the year. The temperature determines
if it stays liquid or solid.
• Thunderstorms are most common on hot summer
days.
• When lightning crosses the sky, the air around it
becomes so hot it causes an explosion, thus
creating thunder.
• Earth is struck by lightning almost 100 times per
second!
• Snow is frozen precipitation that
falls from the sky.
• No two snowflakes are alike.
• Snowflakes have two shapes, stars
and needles.
• The temperature must be below
freezing in order for snowflakes to
form.
• Hurricanes are storms that form
over warm open oceans.
• Depending on where you live, a
hurricane can have a different name:
typhoons, cyclones, or willy-willies.
• Hurricanes can have winds that
reach more than 155 mph.
• Hot humid air from the Gulf of Mexico along with
cool air from Canada produce a violent rotating
column of air reaching from a thunderstorm or cloud
to the ground.
• Tornadoes can produce winds that reach up to 300
mph.
• In an average year 1000 tornadoes are reported
nationwide.
• Texas, Oklahoma, Kansas, and Nebraska create the
best conditions for tornadoes.
• Fog is created by water vapors condensing in the
air. It can make it hard to see for several feet up
to a half mile.
• When the water vapors from the fog are more
widely spread apart, it creates mist.
• Visibility in misty conditions can range from a
half mile to three miles.
• Temperature can vary depending on where you
live. It is also measured by different scales:
Fahrenheit, Celsius, and Kelvin.
• Temperature is measured by using a
thermometer.
• The coldest temperature recorded, was in the
Vostok region in the middle of the Antarctic on
July 21, 1983 at -128˚F.
• The hottest temperature recorded was in the
city of Al Aziziyah in Lybia on September 13, 1922
at 136˚F.
