The Tilt of the Earth
The Revolution of Earth
The revolution of the Earth plays a very important role in space.
Revolution
is the movement of one object around another.
Rotation
is the spinning of Earth on an axis.
Earth's rotation causes day and night,when the Earth is facing the sun, its day, but when the Earth is not facing the sun, it is night.
One complete revolution is equal to 365.25 days.
The revolutions is followed by a path, or an orbit.

Winter Solstice
The rays of the sun...
Direct Sunlight: Sunlight that strikes the most in a specific area, causing it to be warmer.
Indirect Sunlight: Sunlight that doesn't strike close to a certain area with direct sunlight..
The Tropic of Cancer and the Tropic of Capricorn have indirect sunlight, during the equinoxes.
The tilt of the Earth impacts many things such as...
The seasons-Winter and Summer solstice, and the Spring and Fall equinox.
The tilt of the Earth is 23.5 degrees away from being vertical.
If there was no tilt there would be no seasons, just constant year round temperatures.
The winter solstice is the day the sun is farthest south of the equator.
It happens on December 21st and is the winter solstice in the Northern Hemisphere and the summer solstice in the Southern Hemisphere.
A solstice is when the sun is farthest north or south of the equator.
The summer solstice is the day when sun is farthest north of the equator.
It occurs on June 21st and is the summer solstice in the Northern Hemisphere and the winter solstice in the Southern Hemisphere.

Autumnal Equinox
By: Priyanka Pulvender and Sara Huang
The Autumnal Equinox is when neither end of Earth is tilted towards the sun causing both hemispheres to receive the same amount of energy.

During this time, Earth gets 12 hours a day and 12 hours a night.
It happens around September 22 and is when Earth receives the season of fall.
Vernal Equinox
The Vernal Equinox is the same as the Autumnal Equinox. It is when neither end of Earth is tilted towards the sun causing both hemispheres to receive the same amount of energy.
During this time, Earth, again, gets 12 hours a day and 12 hours a night.
It happens around March 21 and is when the Earth receives the season of spring.
