What Causes the Seasons?
The Short Answer:
Earth’s tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun’s most direct rays. So, when the North Pole tilts toward the Sun, it’s summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it’s winter in the Northern Hemisphere.
It's all about Earth's tilt!
Many people believe that Earth is closer to the sun in the summer and that is why it is hotter. And, likewise, they think Earth is farthest from the sun in the winter.
Although this idea makes sense, it is incorrect.
It is true that Earth’s orbit is not a perfect circle. It is a bit lop-sided. During part of the year, Earth is closer to the sun than at other times. However, in the Northern Hemisphere, we are having winter when Earth is closest to the sun and summer when it is farthest away! Compared with how far away the sun is, this change in Earth's distance throughout the year does not make much difference to our weather.
- username90 7y agoYes the seasons are due to earths tilt, but the tilt still doesn't change between seasons as his wife thought, only earths position compared to the sun does.
- barry-cotter 7y agoThe tilt of the earth relative to the sun does in fact change. That’s what the seasons are. If the earth was tilted but the tilt didn’t change over the course of the year the areas that had longer days due to being tilted towards the sun would be permanently hotter than the areas tilted away. There would be a permanent summer and winter, rather as at the equator it’s always summer. The changing tilt of the earth relative to the sun is what the seasons are.
- username90 7y agoI'm not sure what you are trying to say, you probably misunderstood what elcheif said. Earth is tilted towards the sun in the summer and away from the sun in the winter due to its tilt changing, not due to its position changing. That is what you are saying, what I am saying and what elcheif was saying. What elchaif's ex thought was that earths tilt actually changed over the course of the year instead of earth just moving to the other side of the sun. There is no energy which could alter earths tilt like that, instead the tilt was set in motion a very long time ago and has been basically fixed ever since.
- elchief 7y agoshe thought the earth would literally tilt back and forth (as though in place) it's tilted. and it moves to the other side of the sun. so its tilt relative the sun changes. but it doesn't rock back and forth on its own
