What makes the earth tilt back and forth to give us the seasons?

Question

And why does it take the time it takes to orbit the sun to make it for it to tilt in the same position again?

Answer 1

The Earth is tilted by 23 1/2 degrees. During the Summer months,
the north is pointed toward the Sun allowing more direct sunlight.
During the winter, we are tilted away from the sun so the sunlight
is more indirect as the sun seems lower in the sky.
There are 4 cardinal points in our calender;
Summer solstice, autumnal equinox, winter solstice and vernal equinox.
Beginning of summer, fall, winter and spring. This coincides
with the position of earth as it goes around the sun.
Each of the cardinal days can take place over a three day period,
20th, 21st, 22nd. On June 22nd, summer solstice, it is the longest
day of the year. It is also the day that the north pole is pointing
directly at the sun. The next day it will have passed this point
and start pointing away from the sun, hence, the days will also start
getting shorter. For further info,

Answer 2

The Earth axis doesn't tilt back and forth. It's inclination is basically the same except for a very slow small round swing called precession.

The distance to the sun has nothing to do with the seasons.
The difference in distance to the sun between the north and south hemisphere is negligible compared with the distance earth-sun and yet the hemispheres have opposite seasons!

The seasons are due to the angle the sun rays strike the earth's surface depending on your latitude and the number of hours of daylight!

When in the north emisphere is winter the sun rises little above the horizon, which means that its rays must cross a lot more atmosphere and lose much of their heath before they reach the ground. In summer the sun will rise higher and daylight hours increase. That's why in summer is warmer.

Because the axis is tilted with respect to the orbit the sun rays fall at different angles with respect to the earth's surface depending on the latitude and in which hemisphere you are.

Except in the Equator they are close to 90° vertical at noon the all year long. That's why between the Tropics there are basically no seasons as such, only dry and rainy seasons.

Answer 3

The Earth doesn't tilt back and forth it is at a constant at 23.5 degrees tilt.
The north is tilted away from the Sun at Winter and opposite side of Earth's orbit around the Sun the same tilt position makes Earth's north tilt towards the Sun during summer.

Answer 4

It's like the sway of a gyroscope toy or when you spin a coin, except on a planetary level. The reason must be the same for both and contained in the nature of the gravitational forces of the universe and the exact setting of constants.
the movement of th earth depends on two forces mixing together. The Earth has it's own motion and this is like a gyroscope that the sun is always tugging on, preventing from flying off into space.
Some think that not only does the north-south axis tilt causing the seasons but every few thousand years the whole thing flips and the the north pole is now south.

Answer 5

Rotary motion around the sun due to its gravity causes the earth not only to simply spin horizontally but vertically to some degrees too, so when its summer in the north, its winter in the south. The earth has a rotary horizontal cycle but an oscillating vertical cycle and so we get seasons by which hemisphere is facing closer to the sun. Another concept to keep in mind about the earth orbit and anomalies to the above rule is that the earth does not orbit in an exact circle around the sun.

Answer 6

It doesn't tilt back and forth. It is tilted permanantly at 23 degrees. Depending on where it is in the ellipsis of orbit, this tilt will expose different areas of the globe to the sun.

Answer 7

Well, there are enormous Lobsters and Space Goats living deep inside the earths crust.

During their mating season, these immense and majestic creatures are engaged in almost constant humping, and their crude but sexy "capro-homarine" bonking action causes the planet to wobble slightly on its axis, and to squidge up to a certain extent, like a big water-filled balloon.

The randiness of these subterranean Superthings is responsible for various phenomena, such as the turn of the seasons, the precession of the equinoxes, and the fact that the moon only comes out at night.

If you consider it seriously, you will see that there is NO REASON why the moon should come out when the sun goes away, as there is no direct link between their movements. The reason? Immense underearth sex of the massively-endowed goat-lobsters.

Answer 8

Here is a simple way to imagine it.
Take a pencil and tilt it.
Keeping it tilted in the same direction rotate it in a circle around something (a salt shaker or ?).
Did you notice that on one side of the circle the top of the pencil was closest to the salt shaker, and on the opposite side of the circle the bottom was closest.

The pencil was Earth and the salt shaker the Sun.

The Earth is tilted and where it's closest to the Sun is where it's summer.

-The Earth also rotates but for this demonstration you can ignore it.

Answer 9

that is definitely no longer about being closer or extra faraway from the solar, that is a uncomplicated false impression. that is difficult to describe in spite of the undeniable fact that yet right here is going. in case you may imagine shining mild with a torch onto a sheet of paper or card, then it is the solar shining onto the earth. Now, in case you tilt the cardboard you'll see the torch mild is spread out over a larger area. this suggests the mild from the torch is more beneficial spread out and for this reason weaker. that is a twin of the solar and the earth, so as the earth tilts faraway from the solar the incoming radiation decreases and then you've wintry climate. desire that, style of, explains it.

Answer 10

the earth is always at a certain tilt so at some point in orbit around the sun the north pole will be closer to the sun than the south pole and vice versa.
