Rotation and Revolution Vocabulary Test

The four natural divisions of the year based on changes in temperature due to the varied amounts of sunlight (both intensity and number of daylight hours received) caused by the tilt of Earth on its axis during revolution.

• Seasons

• Equinox

• Daylight hours

• Solstice

The path of an object as it revolves around another object in space.

• orbit

• soltice

• axis

• tilt

The imaginary line extending from the North Pole to the South Pole that goes through the center of Earth and is the center of Earth's rotation.

• axis

• tilt

• equator

• solstice

To go around another object or Earth's year-long elliptical orbit around the Sun. Takes 365 1/4 days.

• Revolution

• Model

• Axis

• Rotation

The slant of Earth's axis, or 23.5 (degrees) from vertical compared to Earth's orbital plane around the Sun, resulting in the North Pole always pointing toward the North Star.

• tilt

• day

• axis

• latitude

To spin on an internal axis, or the spinning of Earth on its axis that causes day and night to occur.

• Rotation

• Revolution

• Tilt

• model

The distance north or south from the equator, measured in degrees.

• Latitude

• Hemispehre

• Night

• Polaris

Half of the terrestrial globe or celestial sphere that can be divided by north and south

• Hemisphere

• Direct sun light

• Day

• Revolution

Temperatures are higher where the Sun's rays are direct (summer) and lower where the Sun's rays are indirect (winter).

either of the two times each year (as about March 21 and September 23) when the sun crosses the equator and day and night are everywhere on earth of approximately equal length.

• Solstice

• Equinox

• Polaris

• Night / Day
