Earth's Rotation & Revolution

Sun

• The star at the center of earth's solar system.
• A region of the globe that observes a uniform standard time brought about in 1884 by train travel. There are 24 of these on Earth.
• The season experienced when earth is toward the sun thus receiving more direct sunlight. When it is this season in the Northern Hemisphere, it is the opposite season in the Southern Hemisphere.
• The tilt of Earth's axis. This tilt is responsible for the 4 different seasons.

Axis

• An imaginary line that passes through the center of earth extending out of the North and South Poles. Earth tilts 23.5 degrees on this.
• This is a day in which earth has about equal parts of day and night. It marks the start of fall and is around September 21st. It is the autumnal ______?
• To spin on an axis. It takes earth 24 hours to spin on its axis in one day.
• The season experienced when Earth is tilted away from the sun thus receiving less direct sunlight. When it is this season in the Northern Hemisphere, it is the opposite season in the Southern Hemisphere.

Rotate

• To spin on an axis. It takes earth 24 hours to spin on its axis in one day.
• The length of one year on Earth. It is how long it takes Earth to revolve around the sun.
• The tilt of Earth's axis. This tilt is responsible for the 4 different seasons.
• This is a day in which earth has about equal parts of day and night. It marks the start of fall and is around September 21st. It is the autumnal ______?

Revolution

• To go around. This is Earth's path or orbit around the sun. It takes 365.25 Earth days to make one complete one of these around the sun.
• An imaginary line that goes north and south through the Pacific Ocean. One day is on the east side of the line and the following day is on the west side. It is not perfectly straight.
• The tilt of Earth's axis. This tilt is responsible for the 4 different seasons.
• The length of one year on Earth. It is how long it takes Earth to revolve around the sun.

24 Hours

• The cycle of one Earth day. It is one complete rotation on its axis.
• The imaginary line of latitude which runs through earth's middle and that divides the Earth into the Northern Hemisphere and Southern Hemisphere.
• The tilt of Earth's axis. This tilt is responsible for the 4 different seasons.
• This is a day in which earth has about equal parts of day and night. It marks the start of spring and is around March 21st.It is also called the vernal ______?

International Date Line

• An imaginary line that goes north and south through the Pacific Ocean. One day is on the east side of the line and the following day is on the west side. It is not perfectly straight.
• The day of the year in which there is the most hours of daylight. It is around June 21st and marks the start of summer.
• This is a day in which earth has about equal parts of day and night. It marks the start of fall and is around September 21st. It is the autumnal ______?
• Divisions of the year, defined by changes in weather and the position of Earth in its orbit around the Sun. These occur because of the tilt in the Earth's axis. Spring, summer, autumn (fall), and winter are four well most recognized of these.

Seasons
