Does the Earth orbit at 90 degrees to its yearly orbit? The answer is yes, and the Earth remains in the same plain or disk all the time. However, the rotation of the Earth around itself is tilted 23.5 degrees. To understand this situation, draw a line from the north pole to the south pole; then tilt this line 23.5 degrees preferably to the left, although tilting could be arbitrary to the left or to the right depending on the location of the Earth with respect to the center of the Milky Way. Now the Earth rotates around that tilted axis once a day and the rotation of the Earth around that tilted axis remains as is if you are concerned about the whole yearly rotation. The Earth's orbit around the Sun, however, doesn't change and remains 90 degrees on the same plain during its orbit all the time. It does not fluctuate up and down and changes its plain from year to another. The wobbling of the Earth is not part of your question, but if you wish to understand the wobbling of Earth during the years while the Earth orbits the Sun, then you have to imagine the change of the polar star during the progress of time. The tilted axis of the Earth points to the polar star at the current time, however, the tilted axis moves one degree every 70 years away from the polar star and changes therefore the polar star depending what star is located on that circle of rotation. The star Vega will become our Polar star in 12000 years resulting in changing the time of summer and winter on the Planet Earth. When the star Vega becomes a polar star, the beginning of the summer for the northern hemisphere will begin around December 20 or 21, not June 21 as it is right now. The return of the current polar star, namely Polaris to become the polar star again happens once every 26000 years. Now, If you consider the Moon's orbit around Earth and question whether the Moon maintains 90 degrees in its plane around Earth, then the answer is no. The Moon fluctuates up and down on its plane of orbits around Earth. They call the fluctuation of the Moon and the change of its plain of rotation around Earth as the nodes of the Moon. This is why we don't have solar or lunar eclipse every month.

The tilt of the Earth's North/South pole axis is about the same angle as if you were holding a pencil and were trying to make a sharp dent in a piece of paper (23.5 degrees).
You'll notice the pencil is not quite straight up and down, which would be perfectly 90 degrees to the table that the writing paper is on. And if you're like me and want a really precise, deep dent in the paper, the pencil will not quite be at normal writing angle either. You're probably holding the pencil a bit straighter than when you write, but not perfectly up and down.
That angle is about the angle of the Earth's north/south poles. The table that the paper is on is the solar "plate".
This same angle holds true (with only a little wobble) as the Earth rotates on its plate-like orbit around the sun.

O.ok., for starters-if the Earth stopped rotating on its axis, there could be little stream interior the ambience to boot through fact the oceans. this might effect the two our climate and the temperature of the ambience-plus its potential to get rid of impurities (smog, volcanic ash, and so on.). If the Earth have been to end in its orbit around the solar, it does no longer have sufficient forward velocity=centrifugal stress, to maintain an outstanding course. ultimately gravity (the two from the solar or outer area), might take over, at which factor it quite is a one-way fee tag to the two of those. so some distance, i did no longer see any point out of the Moon in those solutions. through fact it quite is held in stress wager. the Earth and the solar, it would maximum in all likelihood hit Earth in the two situations. that's a foul hair day. Afterthought-it would even influence plate stream under the Earth's crust, too. no longer that it would count-through fact all and sundry could be long previous. This (plate tectonic component), is yet another question...

Actually the earth's axis of rotation encloses approximately 23.5 degrees with the "vertical", that is, with the lines perpendicular to the plane of the orbit. So no. And also, that angle slightly varies over time - which may have been a cause of many climatic changes during the planet's history.

The core of the Earth is revolving closer and closer to the crust of the Earth, Faster, to the 85th degree latitude and 230th degree longitude. Scientists don't know what they are up against? Science is keeping it all a secret.

No, it is out by about 25 degrees, which is why we have seasons.
