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.

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.
How would global warming affect fruit and vegetable seasons?
Because a change in the earths temperature can cause effect the way fruits and vegetables grow
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.
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.
Does the suns revolutions cause the seasons?
no. the earths orbit cause the seasons
Does the sun's revolutions cause the seasons.?
no. the earths orbit cause the seasons
What is gravitys affect on Earths revolution around the sun?
The forces that exist on account of gravity are the cause of Earth's revolution around the Sun.
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 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
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.
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.
In addition to the revolution of the earth around the sun what contributes to the seasons you experience?
Seasons result from the yearly revolution of the Earth around the sun and the tilt of the earth's axis relative to the plane of revolution. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to go into hibernation or to migrate, and plants to be dormant.
What is the sun's highest point in the sky called?
what are two cause of earths seasons
