Earth's Tilt and Seasons Flashcards

Front

Axis

Back

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

Front

Direct

Back

In the shortest unbroken line; temperatures are higher where the Sun's ray are direct

Front

Hemisphere

Back

Half of a sphere; Earth and the celestial sphere can be divided into northern and southern or eastern and western hemispheres

Orbit

Back

A curved path followed by a satellite as it revolves around an object

Front

Revolution

Back

The movement of one object around a center or another object

Front

Seasons

Back

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

Front

Tilt

Back

The slant of Earth's axis, which is 23.5 degrees from vertical compared to Earth's orbital plane around the sun, results in the North Pole always pointing toward the North Star
