summer, fall, winter, spring
global warming...or if you mean seasons its because the earth rotates on its axis
Becuz earth rotates on its axis
We have seasons, because the earth rotates around the sun, and where we are in the solar system effects what season we're in.
the Earth rotates on an axis, that axis is tilted with respect to the axis of Earth's orbit, and Earth's orbit is slightly elliptical.
The imaginary line in which the Earth rotates is called its axis. The Earth's axis is tilted at an angle of approximately 23.5 degrees with respect to its orbit around the Sun, which causes the changing seasons.
How does the earth rotate on its axis??it rotates on
Earth rotates on its axis.
The Earth's axis is tiled 23.4 degrees. It tilts away from the perpendicular of its orbital plane which is why seasons are produced on Earth. The earth rotates on its axis 266.26 times each year.
On the contrary, we have seasons precisely because the Earth's axis is tilted.
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
as the earth rotates the climate and temprature changes. the sun rotates and the seasons change. then every year the earth completes a revolution and then you have winter/summer again....*.*.*.* LoLa*.*.*.*-it is also because the earthes axiz is on a tilt. if the earth was just all strayt up, we wudnt have seesons.
Pretty much every planet has an axis, because an axis is what a planet rotates around. Any planet that rotates has an axis, and pretty much every planet known rotates.
