The earth's 365+ day journey around the sun is of course an important part of what makes a year a year. But if there were no tilt to the earth's pole there would be no change of seasons; depending on latitude, there would always be the same general weather no matter where earth is in its orbit. So there would technically be a year, but with no variation in seasons there would not have been the same motivation to figure out the meaning and importance of earth's orbit. If there were no tilt (it is currently about 23 degrees 26 minutes or about 23.5 degrees) then the sun would always be in earth's equatorial plane; the sun would always be exactly over the equator. Every spot on earth (except very near the poles) would have equal lengths of sunlight and night time, all year. At the poles, it would always be a strange kind of dawn/sunset, with the sun creeping around the horizon, never higher and never lower. There would probably be no polar icecaps. The elliptical shape of earth's orbit would have no appreciable affect on weather at all, because the angle of the sun's rays (which would be invariable over the course of a year) is much more important than the changes in distance from the sun that are inherent with elliptical orbits around a star. Because the spinning of the earth causes the earth to resemble a top, the pole is virtually always oriented in the same direction (north pole facing the star Polaris, currently). So the effect of the tilt is that the sun reaches its high transit point in the sky and its low transit point in the sky (the solstices) once each during the period we call a year-- one full revolution around our sun.
What else can I help you with?
The earths rotation is direct cause of?
seasonsRotation around the sun gives the seasons because the earth is tilted. Rotation about earth's axis give day and night.
How long does the revolution take to go around the sun?
It takes 365 solar days for the Earth to make a revolution around the sun. The distance of the Earth from the sun along with it's access are what cause the change in seasons. The speed of the orbit is he speed is 108,000 km/h.
What inpact do rotations and revolutions have on phenomena on Earth?
ALL life adapts to those cycles - day and year. Little changes cause adaptations ... big ones would cause death.
When the motion of earth around the sun it mostly affect the?
The motion of Earth around the Sun is the cause of the seasons.
Does the Moon's movements around earth have anything to do with the seasons of the year?
The Moon's movements about the Earth , 1 mo(o)nth, cause the tides to have Spring Tides and Neap tides, on a monthly basis. The Seasons of the Year are cause by the Axial tilt of the Earth towards the Sun. Currently, this axial tilt is 23.5 degrees, and reducing. It is calculated that the axial tilt will reduce to 21 degrees and them rise to a maximum of 29 degrees. This movement in the axial tilt is named 'Precession'. All spinning objects precess, and the Earth is no exception. However, it will take thousands of years for one precession, but it will affect the climate. The smaller the angle of tilt it is thought that the seasons will be less extreme. The greater the angle of tile the more extreme the seasons,
Does the sun's revolutions cause the seasons.?
no. the earths orbit cause the seasons
Does the suns revolutions cause the seasons?
no. the earths orbit cause the seasons
What is the most important cause of earths seasons?
The actual most important cause of Earth's seasons is it's axis.
What does revolution cause?
seasons
What does Earths' revolution around the sun cause?
The increment of one calendar and solar year per revolution (by definition), the changing pattern of different stars and constellations, and, to an extent, planets visible from the night side of Earth, tidal effects, and tiny gravitational perturbations of the Sun and nearby planets' positions. Very tiny. The Earth's revolution around the Sun does not, by itself, cause the changing seasons. That is a common misconception. The Earth's polar spin axis is not exactly perpendicular to its orbital plane. It is tilted. This accounts for the seasons far more than revolving around the Sun, although neither would work without the other.
What is the cause earths seasons?
the way the earth spins arund the sun causes the seasons.
How does the earths orbit around the sun cause the seasons?
Actually, it doesn't. The TILT of the Earth on it axis causes seasonal changes.
What are the two factors that cause the earth's seasons?
rotation of earth -earth is at a tilt so sometimes some parts get more sun then others rotation around the sun -earth will be at different distances from the sun as it rotates around
Does the earths revolution cause the seasons?
The revolution of the Earth does not cause changes in the seasons. The TILT of the Earth does. When an area tilts away from the sun, light strikes the earth at a shallow angle, delivering less heat and light. As it tilts towards the sun, light is striking at a more direct angle, delivering more heat and light.
What is the sun's highest point in the sky called?
what are two cause of earths seasons
What two things cause the seasons to change on earth?
There are two things that cause it which are the earths orbit and thetilt of the earths axis.
The earths rotation is direct cause of?
seasonsRotation around the sun gives the seasons because the earth is tilted. Rotation about earth's axis give day and night.
