• Are WEATHER
and
CLIMATE the same thing?
NO!
Then, what is the difference?
Weather• Weather is the condition of the bottom layer
of the earth’s atmosphere . - What is going on outside right now.
THE SUN & THE EARTH
• The sun is of course the ultimate source of the earth’s climate.
• Because of the earth’s position and Revolution around the sun, we experience different climates in different areas.
Rotation• The earth ROTATES once
every 24 hours.
• It completes one Revolution once every 365 ¼ days and is tilted 23 ½ degrees.
Summer & winter
SOLSTICESoccur when the sun,
at noon,
is directly over
the Tropics of Capricorn & Cancer.
Greenhouse Greenhouse EffectEffect
• Earth’s atmosphere acts as a greenhouse trapping 50% of the sun’s heat radiation.
• Clouds, water vapor and carbon dioxide absorb the heat reflected by the earth and radiates it back again to keep the balance
Global WarmingGlobal Warming
Scientists claim that there has been a rise in CO2
levels and that has caused
a rise in global temperatures.
Global WarmingGlobal WarmingBurning of coal, oil and natural gas
has caused the CO2 levels to rise
- increased burning will trap more heat in the atmosphere
Global WarmingGlobal Warming• Some scientists predict that Global Warming will cause extreme global weather patterns such as rapid water evaporation causing drier soils between rain and humidity might increase due to rapid evaporation in the oceans.
