The action or process of rotating on or as if on an axis or center.
Rotation :)
The objects orbital motion around another object.
Revolution :)
While Earth travels through space around the sun, it also spins on its axis, a solar_____ is the time it takes the Earth to turn around once with respect for the sun.
Day :)
A _____ Is the time the Earth takes to make one complete revolution around the sun.
Year :)
The ______ is used to describe the orbits of the planets of the solar system.
Ellipse :)
When the moon passes between the Earth and the sun, the sun is hidden. This is called a __________.
Solar Eclipse :)

Arctic Circle :)
An ______ is an imaginary line around an object that spins. Like the Earth spins on its _____ once every 24 hours.
Axis :)
An _____ _____ is one of 2 points on the major axis of an ellipse whose separation from the other focus determines the shape of an elliptical orbit.
Focus of Orbit :)
An ____ is a regular, repeating path that one object in space takes around another object.
Orbit :)
There are generally 4 ________: Northern, Southern, Eastern, and Western.
Hemispheres of the Earth :)
A _______ is a period of the year that is distinguished by special climate conditions.

An _____ is a conical shadow excluding all light from a given source.
Umbra :)

_____ literally means to stand still. Also the ______ is the point where the sun appears to reach either the highest or lowest in the sky for the year.

Summer Solstice :)
The ____ _______ marks the exact moment when half of the Earth is tilted farthest away from the Sun.
Winter Solstice :)
The ________ _____ is an imaginary line around the Earth, parallel to the equator at latitude 66 degrees.
Antarctic circle :)
This is a day usually on March 21st, when day and night are usually equal length.
Vernal Equinox :)
The ______ is an imaginary line around the middle of a planet.
Equator :)
This is 2 moments of the year when the sun is exactly above the equator and day and night are of exact equal length.
