like in summer here, it is winter in th south, and autumn here, spring south. why is it like this? how come it isnt 1 season for both sides?

A season is a subdivision of the year, marked by changes in weather, ecology, and hours of daylight. 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.
During May, June and July, the northern hemisphere is exposed to more direct sunlight because the hemisphere faces the sun. The same is true of the southern hemisphere in November, December and January. It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux. However, due to seasonal lag, June, July and August are the hottest months in the northern hemisphere and December, January and February are the hottest months in the southern hemisphere.

The earth is tilted from straight up and down position, in relation to the sun. So it takes about 365 days to go around the sun, once So , if you can picture the earth in July, with the part above the equator leaning toward the sun, it is closer and gets more direct rays. As it goes around 1/2 way, the bottom half has moved toward the sun and the top half moved away. It's cold up north, and warm down south.
If also has to do with the angle of the rays hitting the earth. If they hit , head on, like 90 degrees,they're not going to bounce off, like rays in the winter, that are at low angle. In the winter, the sun doesn't
move much above the horizon from morning to night, so the rays are at low angle, and bounce off, without heating the earth so much.

The Earth is tilted on it's axis 23 Degrees. When you are having summer in the Northern Hemisphere, It is tilted Towards the Sun and the Southern Hemisphere is tilted away from the sun and is having Winter.
When you are tilted away from the sun you receive less sun light.
When you are tilted away from the sun you receive less sun light.

Because the earth is tilted at an angle of approx. 23.45 degrees, meaning that at any given time, either the top or bottom half of the earth will receive more sunlight, causing different temperatures and weather (aka seasons!).
