What causes the seasons?

Question

What causes the seasons in each hemisphere?

Answer 1

The fact that the Earths rotational axis is 'tilted' with respect to its orbital axis about hte Sun. This causes the length of 'day' and 'night' to vary as the Earth orbits the Sun and, as a result, different amounts of solar energy are absorbed at different times of the year. This, in turn, causes temperatures to ofluctuate and drives the Earths big weather machine.

Answer 2

Many people believe the seasons are caused by varying distance of the earth from the sun. Even in this day and age! Truly, it is the angle of the sun on a particular hemisphere. This is also why the seasons are different in each hemisphere.

Answer 3

The fact that the earth is rotating slightly out of kilter [the axis of revolution is not perpendicular to the axis of our orbit around the sun] means there is a shift in the difference between the distance from a point on the earth and the sun. Its only a small seasonal change but enough to make it cold in winter and hot in summer. Because of the symmetric nature of the axis, it means that summer in the northern hemisphere matches to winter in the southern hemisphere, and equatorial countries dont experience such a drastic seasonal change as those nearer the poles.

Also the earths orbit is slightly elliptical.

Answer 4

Have you ever spun a top? It goes 'round and 'round. This is the way the earth rotates and causes the sunrise and sunset (because the the sun does not move but the earth does.) The earth also tilts. When the northern hemisphere tilts toward the sun, it gets more heat, thus it is warmer and the outher hemisphere is further away, thus it is cooler.A neat way to demonstrate it is to hold a flashlight and shine it on a ball. rotate the ball and it is light on one side at a time. Tilt it and it is closer or farther from the light.

Answer 5

It has to do with the Earth's place around the sunlight. The Earth revolves around the sunlight and while the Northern Hemisphere is dealing with the sunlight this is summer and while it is not this is winter yet while this is summer interior the Northern Hemisphere this is winter interior the Southern Hemisphere. by way of fact while the Northern Hemisphere isn't dealing with the sunlight the Southern Hemisphere is dealing with it. yet while the two hemispheres are dealing with the sunlight on the comparable perspective this is the two Autumn or spring. Get it?

Answer 6

The fact that the earth turns.
