What causes the seasons?
- A lesson on the Earth's tilt
Aim: What causes the change of seasons?
SWBAT: Describe the reason for seasonal changes on the planet Earth.
Axis: A North to South imaginary line through the center of a planet around which that planet spins
Equinox: Equal day and night.
Solstice: "sun standing still"
Winter Solstice: shortest amount of daylight
Summer Solstice: longest amount of day
• Seasons are due to the tilt of Earth on its axis.
• The part of Earth that is tilted toward the Sun has more sunlight, stronger sunlight, and warmer temperatures than the part tilted away from the Sun.
• Seasons change as Earth revolves around the Sun.
• These seasonal changes result in the winter and summer solstice and the spring or vernal and fall or autumnal equinox.
• Colder weather is the result of one-half of Earth being tilted away from the Sun.
• Warmer weather is the result of one-half of Earth being tilted away from the Sun.
Questions:
How many hours of day and night will earth receive on March 21 – September 21 – June 21 – December 21?
