how does the earth tilt effect the seasons??

Answer 1

The Earth's tilt causes the Sun to apparently move higher and lower in the sky. It also affects how long the Sun is in the sky. The higher the Sun is in the sky, the longer it will remain in the sky. The combination of both means more solar radiation strikes the Earth at that point. The more solar radiation, the hotter it gets.

The reverse also happens. The lower the Sun, the less time in the sky, the less heat heats the surface.

In addition, there is a lag time so that when the Sun is at its highest point, it isn't the hottest on the surface. It takes about 6 weeks for the heat to reach its peak. And, again, the reverse is true. The Sun's at its lowest point and then, six weeks later, the temperature is at its lowest.

The highest and lowest points are called solstices.

In addition, there are two days there the lengths of day and night are the same... the equinoxes. On these days, the effect is if the Earth had no tilt

In many countries (including the US), the day of the highest Sun is the start of Summer. The day of the lowest point is the start of Winter. The 2 equinoxes are the start of Spring and Fall, with Spring being on the equinox between Winter and Summer and Fall being on the equinox between Summer and Winter.

Other countries have the solstices and equinoxes being the mid-point of the season

I hope this helps

Answer 2

The tilt of the earth's axis and the revolution of the earth around the sun both contribute to the formation of seasons.Because of the tilted axis ,the northern hemisphere is pointing towards the sun(summer for NH) at the apogee (farthest)position of the elliptical orbit and the southrern hemisphere is pointing towards the sun at the perigee(nearest)Position bringing the summer to the southrern hemisphere.
If the revolution is not there, the apparent movement of the sun between the tropic of cancer and the tropic of capricon will not be there and the earth will be stationary and will be spinning always in a particular direction from the sun .
The tilt of the axis (without the revolution) will only cause difference in day time and night time .

Answer 3

Ok heres a little visual for you the letter o is the sun. Sun = (o) with the perentesies =sun's rays pay attention to its location. / , \ , l are the tilt.. now America is at the top of the slashes ok.


Winter = \ (((((o))))) Dirrect rays hit more to the south
Spring = l (((((o))))) Dirrect rays hit Equater more
Summer = / (((((o))))) Dirrect rays hit more to the north
Fall = l (((((o))))) Dirrect rays hit the Equater again

This changes both the temperature of the days and the length of the days. The extea length of the day also gives more time to heat the surface and less and a shorter night gives less time for it to cool down again.
Though the Equater doesn't have seasons not the visual the rays are always hitting it first. It's always 12 hours day and 12 night. How boring ha

Answer 4

When the earth is tilted toward the sun, we have the warmer seasons but when it is tilted away from the sun, we have the colder ones. The least extreme seasons occur closer to the equator between the tropic of cancer and tropic of capricorn.
Also hours of daylight are effected with the seasons the closer you get to the poles. I have heard from people who have gone to Alaska that in the summer, you have 22 hours out of 24 of daylight but in the winter, it is the opposite with only two or three hours of daylight.
