EARTH-SUN RELATIONSHIPMaira Mulla and Lilly Doan
EARTH AND THE SUN
https://youtu.be/R2lP146KA5A
As you can see in the video above the Earth orbits the sun in a unique way. This effects many day to day things that happen on Earth.
WEATHER AND CLIMATE The Earth’s position with the Sun effects many day to day
factors like weather and climate. The tilt on Earth’s axis (23.5 degrees) effects where sunlight
may be in different areas.
For example,
The North could be getting more sunlight because it is tilted more towards the sun, while the earth rotates on its axis.
Because of this unequal heating depending on where the earth is to the sun, we have seasons!
EQUINOX AND SOLSTICE Equinox’s happen twice a year and shift seasons. Equal day and Equal night
March 21- Spring Equinox
September 23- Autumn Equinox
Solstice’s also happen twice a year and shift seasons
June 21- Summer Solstice (longest day of the year) The sun will have direct rays on the Tropic of Cancer. NORTH
December 22- Winter Solstice (longest night of the year) The sun will have direct rays on the Tropic of Capricorn NORTH
POLES
The poles are effected the most from the Earth and Sun as one pole may receive no sunlight for up to 6 months while the other will receive continuous sunlight for 6 months.
THE GREENHOUSE EFFECT
Warming of Earth’s atmosphere. 50% of the Sun’s radiation is absorbed into
heat. Atmospheric gasses absorb this so it does
not escape. Without it the greenhouse effect, we would
not have sustainable temperatures. https://www.youtube.com/watch?v=VYMjSule
