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
