Why Earth has 4 seasons?
Nearly everyone enjoys the change of seasons on Earth – from winter to spring, from summer to fall. But why do our seasons change?
Some assume our planet’s changing distance from the sun causes the change in the seasons. That’s logical, but not the case, for Earth. Instead, Earth has seasons because our planet’s axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth’s orbit around the sun.
The tilt in the axis of the Earth is called its obliquity by scientists.

Phoenix Williams yeah like in Phoenix they have summer, hot summer, extended summer, and almost summer.
ReplyDeleteStrictly speaking "earth" doesn't have four seasons. This is true for the so-called temperate regions, but in some parts of the world there are two or three seasons.
ReplyDeleteStrictly speaking, depending on where you move your anatomy on this planet you might get to feel and see more than one season. I like diversity so from my "location-anatomy" point, Earth has 4 seasons. ;)
