Sun's Effect on Earth's Climate
North Pole vs. South Pole
Direct vs. Indirect light
Direct sunlight :
The Sun's energy is focused on the Earth's surface directly
More intense, temperature rises
Near the equator
Indirect sunlight:
Sun's energy hits surface at an angle
Less intense, temperature decreases
North and South Pole
Earth's tilt
Bibliography
What is the purpose of the Experiment?
Direct Sunlight
Indirect Sunlight
Indirect Sunlight
South Pole is a lot colder than the North Pole.

Both are dark and cold.
North Pole is above the equator.
South Pole is below the equator.

Both get the same amount of sunlight.
Both have 2 seasons: Summer and winter.
The north Pole is ocean surrounded by land.
The ocean is a bit warmer underneath the ice which warms up the air.

The Sun
The sun is the center point of any solar system.
The earth is tilted at about 23.5°.
The sun takes up nearly 99.86% of the total mass in the solar system.
The sun is about 150 million km away from earth. ( 93 million miles )
The sun is made up of 74% Hydrogen, 25% Helium, and 1% other chemicals. (Measured by mass)
The sun if nearly 4.5 billion years old.
The temperature of the sun's surface is 5,778°C (10,000°F)
Effect of Sunlight on climate
The angle where the sunlight hits the surface of the earth varies by
location
Time of day
Season due to the earth's orbit around the sun and the earth's rotation around its tilted axis.
Seasonal change in the angle of sunlight, is caused by the tilt of the earth's axis.
This results in warmer weather in summer than in winter.
