why does the earth have different season throughout the year?

Answer 1

What causes the earth to experience different seasons?

Have you ever wondered why the earth experiences Fall, Winter, Spring, and Summer? Generally, the Northern Hemisphere will experience different climate conditions than the Southern Hemisphere. For instance, one hemisphere will experience the cold conditions of winter while the other hemisphere experiences the warmer conditions of summer. This is illustrated in the picture at left which shows the Northern Hemisphere countries of the U.S., Canada, and Mexico experiencing the warm conditions of summer while the Southern Hemisphere experiences the cooler conditions of winter. The image on the right shows the reverse: the Northern Hemisphere is experiencing Winter while the Southern Hemisphere experiences Summer.

Did you know that our four seasons exist because of the tilt of the earth on its axis and because of the earth's orbit around the sun? The manner in which this factor produces our seasons is very easy to explain. Take a few moments to think about how this may occur

If the Earth had only one season throughout the year, the human, and the other kinds of living beings may face difficulties to survive on planet earth.

Answer 2

Seasons occur on the Earth because of the tilt of the Earth's axis. Because the Earth's spin is not exactly aligned with the Earth's orbit around the sun, the Sun sometimes shines directly over the nothern hemisphere, and other times shines directly over the southern hemisphere. For instance, the sun reaches its most northerly position (the tropic of cancer) on June 21. This is called the "summer solstice." If you were standing on the tropic of cancer on June 21, the sun would be directly overhead at noon. This is the first day of summer in the northern hemisphere, and the first day of winter in the southern hemisphere. Because the sun is shining more directly in the north than in the south, the weather is warmer in the north in June. In December, the opposite happens. The sun is over the tropic of Capricorn, and is shining directly at the southern hemisphere. So December is summer in Australia and Brazil, but winter in America, Europe, and Asia.

Some people believe that summer is when the Earth is closest to the sun. This is not true. In fact, the Earth is farthest from the sun in early July, and nearest the sun in January. Because these differences in distance are so small however, they hardly affect the seasons at all.

Answer 3

It's all on the earth's tilt, some times of year the earth is tilted so that the sun is closer to the northern hemisphere. Which makes it summer time here in the states, and on the other hand the when it the earth is tilted the opposite way, the sun is closer to southern hemisphere, which gives us winter but them summer. The equator is the center so it doesn't matter which way the earth is tilted for it. Also the moons gravity helps regulate the tilt of earth. Which ensures us our seasons.

Answer 4

The tilt of the earth's axis and the orbital motion of the earth around the sun both are causes for the change of seasons.Tilt of the axis brings about variation in daylight hours and the orbital motion is responsible for summer and winter seasons(other seasons in between)
in both the hemispheres.Luckily,for northern hemisphere,the sun is nearest(in its elliptical orbit) during winter and farthest during summer.Otherwise winter will be more colder and summer more hotter.

Answer 5

In winter time, the sun is lower on the horizon due to the tilt of the Earth facing the sun. With the sun lower on the horizon, less heat is absorbed through the atmosphere. In the summer, the sun is higher on the horizon and more heat is absorbed due to direct exposure. Spring and fall are just the "average" seasons in between the two extremes.

Answer 6

Because of the tilt of its axis. Because the Earth is spherical, some part of it is getting more sunlight each year. It really depends on where you are. Regions near the equator is getting the most sunlight, and experience less seasonal changes.

Answer 7

The changes of season are a result of the earth's elliptical orbit and the earth's axis. Picture this like the shape of an egg, when the planet is on the narrow end of the egg it's closer to the sun. When it's on the wide end of the egg, it's farther away and it's winter.

Answer 8

Look at it this way, if we had only one season, what would be the fun of that... God loves variety, thats why he created us all as different unique individuals

Answer 9

It depends on what time of year it is .
