Transcript As the earth revolves around the sun it is tilted at a 23.5 degree

Chapter 3: Section 1
 As the earth revolves around the sun it is tilted at a
23.5 degree angle in relation to the sun.
 The earth’s seasons are related to the earth’s tilt and
revolution
 This tilt causes the changing Seasons on the earth.
 The tilt causes different parts of the earth to receive
Sunlight for more hours of the day at certain times of
the year.
 The longest day of the year is called the Summer
Solstice. This occurs on what day in the northern
hemisphere? June 22nd or June 23rd.
 What marks the farthest point north the sun’s rays
shine directly overhead at noon? Tropic of Cancer
 What marks the farthest point south the sun’s rays
shine directly overhead at noon? Tropic of Capricorn
 The shortest day occurs on December 22nd or 23rd
(Winter Solstice) in the northern hemisphere.
 The day in which the days and nights all over the world
are equal in length is called the Equinox.
 What two seasons does this mark the beginning of?
Autumn (Fall) and Vernal (Spring)
 Define Weather: The condition of the atmosphere
at a particular location and time.
 Define Climate: weather conditions at particular
location over a long period of time.
 What are the major factors that cause weather? Water
vapor, cloud cover, landforms and bodies of water,
elevation, air movement.
 Define Precipitation: Falling water droplets in the

form of rain, sleet, snow, or hail.
What are the 3 classifications of precipitation?
convectional, orographic, frontal
Where does convectional precipitation occur? Hot
climates
Where does orographic precipitation occur?
Windward side of a mountain.
The leeward side of a mountain range is often called a
Rain shadow because it gets little rain.
 A front is the boundary between 2 air masses of different

temperatures.
Circular storms that form over warm tropical waters are
called Hurricanes or Typhoons.
Define Tornado: A powerful funnel-shaped column of
spiraling air..
Define Blizzard: A heavy snowstorm with winds of more
than 35 mph and reduced visability.
Define Drought: A long period of time without rain.
What weather extremes listed in the book are likely to
occur in Texas? Hurricanes, toronados, droughts, and
floods.

and ocean currents, latitude, elevation, and topography.
What is the number one factor in determining climate of a region?
Latitude.
Define convection: Transfer of heat in the atmosphere by upward
motion of air.
Ocean currents are like Rivers flowing in the ocean.
Warm water currents generally flow away from the equator while cold
water currents flow to it.
What are the 3 zones of latitude? Low, Mid, and High.
The warming of the waters off the coast of South America is known as
El Nino
Define Greenhouse Effect: Layer of gases in the atmosphere that
causes higher temperatures.

which 2 types of climate? Semiarid and humid
subtropical.
What are the two most significant factors in defining
different climates? Temperature and Precipitation
What are the 5 general climate regions?
1. Tropical (Low latitudes)
2. Mid latitudes
3. High Latitudes
4. Dry
5. Highland

Topsoil.
Define ecosystem: An interdependent community of
plants and animals.
Maple, oak birch and cottonwood are examples of
broadleaf (deciduous) trees.
Pine, fir, and cedar are examples of Needle leaf or
coniferous trees.
What two types of plant life are you likely to find in the
desert? Cactus and Sagebrush.
A savanna is similar to a Steppe.
Based on the description below
which climate area would you be
in?
 In mountains where temperature varies according to how high you are.
Highland
 Summers are hot and dry and winters are cool and rainy; good agricultural area.
Mediterranean
 Moderated temperatures due to locations next to oceans; frequently experience
foggy, damp, cloudy conditions. Marine West Coast
 Hot, humid summers and mild winters; most often found on eastern coasts of
continents including the U.S. and China; often experience hurricanes; good climate
for agriculture . Humid Subtropical
 Have four distinct seasons with great temperature & precipitation variety based on
latitudes; mostly found in mid-latitudes of the Northern Hemisphere Humid
Continental
 Long, cold winters and short, cool summers; evergreen forests called taiga exist
here. Subartic
Based on the description below
which climate area would you be
in?
 Frigid temperatures, little precipitation and permafrost. Tundra
 Lots of ice and permanently freezing temperatures; AKA polar deserts. Ice
Cap
 Receive less than 10 inches of rainfall a year; can be hot or cool/cold. Desert
 Located on the interior of continents and around desert zones; receive about 16
inches of rain a year; hot summers and mild/cold winters. Semiarid
 Warm, wet summers and dry, cool winters.
Tropical Wet and Dry
 Hot, rainy conditions year around; located in areas around the equator like
Southeast Asia and Northern South America. Tropical Wet
