What are earths four motions?
Earth has four main motions: rotation, which causes day and night; revolution, which causes the annual seasons; precession, which causes a slow wobble in its axis; and nutation, which causes a slight variation in the tilt of its axis.
What are earths motions?
Earth has several motions: rotation around its axis (which causes day and night), revolution around the sun (which creates the changing seasons), and precession, a slow wobble of its axis over a 26,000-year cycle. Earth also experiences nutation, a small irregular motion of its axis caused by the gravitational pull of the Moon and Sun.
What is Axial precession?
Axial precession is a word commonly used in astronomy. Axial precession is defined as being a gravity induced change that takes place during an astronomical bodyâ??s rotational axis which has a slow and continuous pattern.
What causes seasons on Eart?
Seasons on Earth are caused by the tilt of the Earth's axis as it orbits around the Sun. The angle of sunlight hitting different parts of the Earth changes throughout the year, creating variations in temperature and daylight hours that we experience as seasons.
What are the 8 motions of the earth and the meaning?
The eight motions of the Earth are rotation, revolution, precession, nutation, axial tilt, orbital inclination, apsidal precession, and proper rotation. These motions contribute to phenomena such as day and night (rotation), changing seasons (axial tilt), and variations in the position of the Earth's axis and orbit over time (precession and apsidal precession).
The seasons are caused by a combination of Earth's what?
seasons are caused by a combination of the earths ration on it axis and its angel pointed toward or away from the sun
What is a very slow motion of earths axis that requires 26000 years?
precession
What are earths four motions?

What evidence of the tilt of earths axis?
Seasons

Earth also experiences nutation, a small irregular motion of its axis caused by the gravitational pull of the Moon and Sun.
When was the Precession of equinoxes?
21,000-26,000 years, caused by wobble of earth about its axis.
How is the movement of the celestial pole caused?
The movement of the celestial pole is caused by Precession of the Earth's rotational axis.
What do you call the slow movement of earths axis with a period of 26000 years?
Procession of the Equinox
How does the tilt of earths axis and its rotation affect the weather?
The same way it affects most of earth. The seasons are caused by the tilt of the earth's axis relative to the plane of its orbit.
What happens if earths axis were vertical?
There would be no seasons.
What does earths tilted axis affect?
Seasons And Climate
How would you describe what causes the seasons?
its earths tilt on its axis orbiting the sun
