Weather vs. Climate
Weather – condition of the
atmosphere in one place during a short period of time.
Climate – weather patterns typical
for an area over a long period of time.
Creating Seasons Revolution
– Orbit around the sun Rotation
– Earth rotates on its axis - 24 hours – from west to east.
Axial Tilt– Earth is tilted at 23 ½ ° differing the amount of
sunlight throughout the year.
Creating Seasons
Equinox– March 21 and September 23, suns rays on the
equator. Spring and Fall Solstice
– June 21, north hemisphere receives the most sun, Dec 22 Southern hemisphere receives most sun. Summer and Winter.
Creating Seasons
Eight Factors That Affect Climate
Latitude
Air Pressure
Mountain Barriers
Elevation
ContinentalLocation
Ocean Currents
Wind Currents
Storms
Latitude Major change
to climate Change as
you move North to South
Equator = direct rays = hot
Poles = indirect rays = cold
Air Pressure Caused by unequal
distribution of earths heat.
LP = warm, moist air rises → forms clouds → storms.
HP = cold dry air → sinks → stable and clear.
Mountain Barriers a.k.a. - Orographic
Precipitation a.k.a. – Rain Shadow
Effect
Windward side – Warm, moist air → up
windward side → cool moist air drops precipitation
Leeward side– Warm dry air → down
leeward side → little to no rain.
Elevation How far above sea
level you are. Every 1,000 feet
temperature changes 3.5°F.
Continental Location Water heats and cools more slowly than land. Coastline areas have stable temperature. Interiors of continent have extreme temperature
changes.
Ocean Currents Warm-water currents -
equator to the poles. Cold water currents - poles
to the equator. Coriolis effect – The
currents circular patterns are opposite of one another due to the Earth’s rotation.– Northern Hemisphere –
clockwise– Southern Hemisphere –
counter clockwise.
Wind Currents Air in high pressure
rushes into areas of low pressure – this causes wind.
Helps to distribute earth’s heat.
Coriolis effect
Storms Clashes between
warm and cold air masses– Hurricanes – tropical
storms moving heat from tropics.
– Tornadoes – powerful funnel shaped spiraling air.
Homework
Read page 58 in your textbook, section titled “The Greenhouse Effect”. (total of 6 paragraphs)– Answer the following questions,
Why is the earth’s atmosphere referred to as being like a greenhouse?
What human activities have caused there to be high levels of CO2 in the atmosphere?
Analyze the diagram on page 70. – Answer questions 1-4 in complete sentences.
