How do seasons occur? (urgent)?

Question

Hello, I was wondering if you could help with my Homework. I know WHY seasons occur just not how. I get for the WHY that its because of the latitude and axis, so I know that much. BUt I dont know how.
Thankyou!

Answer 1

earth's rotation around the sun ...

IN MORE DETAILS

The seasons result from the Earth's axis being tilted to its orbital plane; it deviates by an angle of about 23.44 degrees. Thus, at any given time during summer or winter, one part of the planet is more directly exposed to the rays of the Sun . This exposure alternates as the Earth revolves in its orbit. At any given time, regardless of season, the northern and southern hemispheres experience opposite seasons and Month ranges of seasons and Effect of sun angle on climate).

I know u may think wikipedia cant be trusted but its got pretty useful info regarding this matter

Answer 2

it has to do with the tropics of capricorn and cancer, when the suns rays reach these lines, seasons occor. The Earth has seasons because it is tilted about 23.5 degrees from straight up and down. Think of the Earth as a spinning top, tipped over to one side. It remains tipped in the same direction as it travels around the Sun. This means that sometimes the northern hemisphere of the Earth is pointing towards the Sun, and sometimes it is pointing away.
When the northern half of the Earth is pointing towards the Sun, the northern hemisphere of the Earth gets more direct sunlight. We call this the "summer" season for the north. At this same time, the southern half of the Earth is pointed away from the Sun, so people in the southern hemisphere get less direct sunlight. We call this "winter" for the southern hemisphere. So, because of the tilt of the Earth's axis, the seasons in the south are the opposite of those in the north.

Suppose the Earth's axis was not tilted. Then everybody would have the same season all year round! No more summer and winter! The Moon is only tipped over about 1 degree. Since it has such a small tilt, each spot on the Moon has the same "season" all year.

Answer 3

Both the tilt of the eath's axis and the orbital motion of the earth around the sun combine together to cause the seasons.If the tilt is there and the orbital motion around the sun is not there,then the earth will remain always in one particular direction from the sun and either the Northern hemisphere or the Southern hemisphere will always be pointing towards the sun. so, there will be permanently summer or winter in one of the two hemispheres.
Similarly, if the tilt is not there (that means the axis is perpendicular to the plane of orbit)and the orbital motion around the sun is there,the sun will always remain over the equator. As aresult, the duration of day and night will be equal in all the places throught the year and as such, there will not be any season again.
So ,the tilt of the axis and revolution of the earth around the sun both contribute to the seasons.

Answer 4

Seasons occur because the Earth orbits the sun on a slanted angle, so that during different parts of the year the sun's light hits the different areas of the earth at more direct or less direct angles over the course of a year. This is why when it's winter in the Northern Hemisphere, it's summer in the Southern Hemisphere.

Answer 5

To put it simply... The Earth is constantly tilted as you know. The sun hits the Earth at different places at different times. When the top of the Earth is bacwards the Northern Hemisphere has winter but the Southern Hemisphere has summer because the sun is hitting the Southern Hemisphere more directly so it is warmer
