Seasons
Throughout the course of the year, the Earth goes through the four noticeable seasons: summer, autumn (fall), winter and spring, each lasting for about 3 months.
What Causes the Seasons?
The landscape and weather change greatly during the year in regions that have four distinct seasons.

The annual seasonal cycle is one example of how celestial events affect the Earth. Tides, caused largely by the gravity of the Moon, are another example.

The seasons are a result of Earth's axis of rotation being tilted 23.5 degrees with respect to its orbital plane.
The Seasons
If you were to talk to the average passer-by, they would probably tell you that the seasons are caused by Earth not having a perfectly circular orbit about the sun, so when it's farther away it is winter and when it's closer it is summer.
The seasons are caused by the tilt of Earth's axis in relation to the sun. The direction of the tilt never changes. But as the Earth orbits the sun, different parts of the planet are exposed to direct sunlight.
The seasons of the year are: spring, summer, fall (autumn), and winter. The seasons are caused by the tilt of the Earth's .
The seasons were to be released in an HD DVD/DVD combination set, with season one released in November 2007. The release of seasons two and three were canceled in February 2008 due to the decline of HD DVDs in comparison to rival format Blu-ray.

4. The seasons of spring and fall occur between the seasons of summer and winter. The order of the seasons is spring, summer, fall, and winter.
Mars has seasons rather like the Earth, but the distance of Mars from the Sun varies much more than the Earth's does and so this effect is correspondingly much greater.

At certain seasons, some areas on Mars are subject to winds strong enough to move sand on the surface and to suspend dust in the atmosphere.
Days and Seasons on Mars
The Martian solar day, or "sol", is about 40 minutes longer than a day on Earth. Consequently Mars only rotates through 350° of longitude in 24 hours.
A CHANGE OF SEASONS ON SATURN
Saturn's rings open up as it moves from autumn towards winter in its Northern Hemisphere.
The real cause of seasons is the 23.5° of the 's rotational axis to its orbital plane.
Saturn experiences seasons as the Earth does, and this causes the rings to appear at various angles from year to year as seen from Earth. The rings are now tilted at nearly 20 degrees, ideal for observation.
"Eventually, as the seasons change over a few years, the convective clouds may migrate northward to lower latitudes," said DelGenio, "If so, ...
The amplitude of this variation changes with the phase of the moon, the seasons, and the sunspot cycle. magnetic memory 1. The ability of a material to retain magnetism after the magnetizing force is removed. 2. = magnetic storage.
The sky abounds with them, northern winter's Castor, springtime's Mizar and Alcor, summer's Albireo (the seasons reversed for the southern hemisphere), dozens of others easily found.
Both of these aspects of the Sun's motion change with the seasons.
Actually, there are two times during the year when the Sun does rise exactly due east and set exactly due west. These times are used to determine the starts of some seasons.
calendar (From Stargazers to Starships Glossary - GSFC) A system of marking days of the year, usually devised in a way to give each date a fixed place in the cycle of seasons.
Thus, the tropical year, measuring the cycle of seasons (for example, the time from solstice to solstice, or equinox to equinox), is about 20 minutes shorter than the sidereal year, ...
I'll show you how the Earth's tilt causes our seasons and affects how we view the night sky. I'll also tell you how other planets are tilted.

If Mars had an Earth-like orbit, its seasons would be similar to Earth's because its axial tilt is similar to Earth's. However, the comparatively large eccentricity of the Martian orbit has a significant effect.
The signs, unlike the constellations, are defined by the seasons. When the Sun stands right over the Earth's equator on the March equinox, this marks the first point of the sign of Aries.
Did the regular procession of the lunar cycle combined with the wanderings of the planets and the stately progression of the stars and Sun with the seasons underpin and prompt thinking about the nature of the Universe?
In the Silver Age, Zeus shortened springtime and introduced the yearly cycle of seasons. Humans in this age became quarrelsome and ceased to honour the gods. Dike longed for the idyllic days gone by.
But in some regions, there is not much differentiation between the seasons. Since different constellations are visible at different times of the year, you can use them to tell what month it is.
Because the axis of rotation is tilted about 25° to the plane of revolution, Mars experiences seasons somewhat similar to those of the earth.

biochemical evidence from South Africa suggest that photosynthetic bacteria (primarily blue-green cyanobacteria, that may have included the ancestors of Chroococcidiopsis) may have colonized the wet surface of clay-rich soil during rainy seasons, ...
Because the length of the lunar month is not an even fraction of the length of the tropical year, a purely lunar calendar quickly drifts against the seasons. It does, however, stay constant with respect to other phenomena, notably tides.
A slightly more subtle point was recognized by ancient astronomers who determined that the Sun moves through the sky on a daily and annual cycles, and that these cycles account for the length of the day and the seasons of the year.
Ozone occurs, in an amount supposed to be associated with the development of atmospheric electricity (lightning, &c.); this amount varies with the seasons, being a maximum in spring, ...
The earliest of Astronomers were holy men and priests, studding the cosmos of celestial bodies for deterring seasons, celebrations, and other events.
It is the axial tilt on the Earth that is largely responsible for the seasons. Inclination measures the angle of inclination of the orbit to the ecliptic (which is defined by the orbit of the Earth around the Sun).
Its water level changes dramatically throughout the seasons. At the time this image was taken the lake was nearly dry. At lower right is the greenish Lake Blanche.
If the Earth's rotation axis were perpendicular to the plain of its orbit, there were be no solstice days and no seasons.

Equinox The two times of the year when the Sun crosses the celestial equator; vernal or spring equinox occurs about March 21st, and autumnal or fall equinox about September 22nd (northern hemisphere seasons).
Axial inclination
axial inclination is the angle at which a planet's axis of rotation is tilted, with respect to that planet's own orbit. On Earth, as well as other planets, this tilt is responsible for the seasons.
Solstice
The time of the year when the Sun appears furthest north or south of the celestial equator. The solstices mark the beginning of the Summer and Winter seasons.
This means that the northern hemisphere of the planet sees the sun continually spinning round in the sky for over 40 years only to be plunged into darkness for 40 more. For the southern hemisphere the seasons are reversed.
