Climate v. Weather Climate Weather Term for weather patterns
that an area typically experiences over time Condition of the
atmosphere in one place during a limited period of time.
Slide 4
Earth Tilt and Rotation Tilt Rotation Axis- imaginary line
running from the north pole to the south through the planets center
Because of the tilt, not all places on the earth receive the same
amount of direct sun light at the same time. The tilt affects the
temperature How hot or cold a place is. Measured in degrees on a
set scale More sunlight= higher temps Less Sunlight = Colder temps
Earth also rotates on an axis 1 rotation ever 24 hours Rotates West
to East, turns one hemisphere then the other toward the sun,
alternating them between the light of day and the dark of
night.

Slide 6
Revolution The earth takes 1 revolution, or trip around the
sun, every 365 days Revolution + Tilt = changes in angle and the
amount of sun that reaches places of the Earth Seasons Seasons are
reversed North and South of the Equator Equinox- day where daylight
and nighttime hours are equal. Around March 21st
Slide 7
Tropics of Cancer and Capricorn Tropic of Cancer- Northern most
point of the earth When the sun directly hits the Tropic of Cancer
the north experiences its longest days of the summer = Summer
Solstice Tropic of Capricorn- Southern most point When the sun is
directly on the Tropic of Capricorn it marks the shortest days in
the North = Winter Solstice
Slide 8
The Poles The most dramatic variation of the amounts of
sunlight happen at the poles The pole angled toward the sun
receives constant sunlight while the pole angled away receives
little to no sunlight North Pole- March 20- September 23 rd is
constant day light, while the south has none South
Pole-September23-March 20 th Constant day light, while the north
has none
Slide 9
Greenhouse Effects Only part of the suns radiation passes
through the earths atmosphere while the rest is reflected back into
space The radiation that makes it through warms the earth and
water. The earth acts like a greenhouse because it traps some of
the suns energy from escaping the earth to quickly this helps w/
growing plants, even in cold weather. With out this earth would be
too cold for most living things
Slide 10
Slide 11
Greenhouse Effect If too much heat escapes, plants will freeze
If too much heat is trapped, plants will wilt and dry out This is
similar to how the earth works
Slide 12
Global Warming Belief that a rise in global temperatures has
occurred due to human activity Examples: burning of coal, oil, and
natural gas Fossil fuels release carbon dioxide, a greenhouse gas,
in the atmosphere that traps more heat

Slide 14
How does latitude affect climate? As latitude ________, the
average annual temperature _________. 0 Latitude 90 Temperature
decreases increases
Slide 15
How does closeness to a large body of water affect climate?
Water __________ the temperature. _______ summers. _______ winters.
City B is closer to a large body of water. Its temperature line is
flatter (moderated). moderates Cities A & B are located at the
same latitude. CoolerWarmer
Slide 16
How does the Orographic Effect affect climate? Windward Side:
___________ Leeward Side: _____________ cool, moist warm, dry
Slide 17
Slide 18
How does elevation affect climate? As elevation _________, the
average annual temperature __________. Elevation Temperature
increases decreases
Slide 19
How do ocean currents affect climate? Warm Currents: warmer
climate Cold Currents: cooler climate

Tropical Climate: Wet Hot and wet Average temperature of 80
degrees About 80 in. of rain yearly Nutrient rich soil Abundant
wildlife Rain forests, example: Amazon River basin Areas with this
climate: South America, Caribbean, Asia, Africa
Slide 23
Tropical Climate: Dry Dry winters, wet summers High year-round
temperatures Fewer trees: Savannas Areas with this climate: Africa,
Central America, South America, Asia, and Australia Sparse Plants:
Deserts
Slide 24
Dry Climate Desert: Sparse plant life Rainfall less than 10
inches 1/3 of Earths total land Sahara is 1/3 of the African
Continent Steppes: Border deserts Treeless grasslands 10 to 20
inches of rain yearly Found in North America, South America,
Africa, and Australia
