Ive forgot my basic geography!How do seasons change?
The Earth spins around an imaginary axis that goes from the North Pole, down through the centre of the Earth to the South Pole (1 spin = 1 day). The Earth also orbits around the sun on a nearly circular track (1 orbit = 1 year). The imaginary spin axis line is NOT at right angles to the orbit path. It’s tilted by 20-odd degrees, so the Earth goes around the sun with some parts getting the sun more “square-on” than at other times. (The seasons) When the bottom of the Earth faces the sun more square on (Southern hemisphere summer) the top half is tilted away so the sun comes in at a more oblique angle and gets warmed less (Northern hemisphere winter.) The easiest way of seeing this by yourself is to google “how do seasons change” for some animations. The easiest way of seeing this with someone else is to expose a bulb (the sun) and to borrow a globe that sits on its tilted axis and get them to move the globe around the bulb. The tricky bit is to keep the angle of the tilt the same with r
