What causes the seasons?

Why do we get the seasons? The seasons? Because of the atmosphere. To be honest with you, that's a very easy question to answer. Now, we really don't get seasons anymore because of global warming. Um, I think there was a time when I was a child where we definitely had four seasons. I think now we get summer, summer, summer, and a little bit of winter in Australia.

Is it to do with the Earth's turning and the equator? Four seasons? What? You mean like summer and winter? And doesn't it come from where we are around the sun? At that stage, that's the season that we're in. I think the position of the Earth, uh, depending on the sun, it's like if the Earth is standing in other positions to the Earth, and there is winter, summer, and in between there’s uh, autumn and what is it? Spring?

Cuz the Earth rotates on an axis, right? And I think so. It goes around on an axis. Well, obviously, the Earth isn't like spinning like that; it's sort of like on an angle 'cause of the axis of the Earth rotating. The Earth rotating around its axis, yeah. What does the axis do?

Uh, it sends you further and closer to the Sun, for example. Now the southern part, Australia, is in winter now, and Europe is in the summer season. And then the north side of the um Earth is standing more close to the Sun, and the south side is like far away from that. It's 'cause the Earth is at a, I think it's a 22° tilt or something like that. So as it goes around the Sun, um, that means that either the north or the southern hemisphere is close to the Sun.

So that, um, things are hotter or colder when the Earth goes around the Sun. It's not a circle; it's an ellipse. So we have different distances to the Sun. So therefore, the further the Sun is away, the colder it is, H, in a country like that. It's 'cause it's like an overall; it's not perfectly clear. It's like so the Sun comes closer this way and further away the uh elliptical pattern of the Earth and the distance from closer to the Sun in summer and furthest away from it in the winter.

Sometimes the Sun is actually glancing the surface of the Earth in certain regions, and other times it's square on, like perpendicular. Well, basically the Sun's rays are more oblique at certain times of the year than others. I think it's because of how the Sun rays are like hitting; when they hit at an angle, it doesn't get that hot.
