No earth's axis is tilted, this tilt shifts over time.
no it is not. the earth is straight up and down. so is the sun.
Then we wouldn't have any seasons.
There is no such thing as straight up and down in space. We, living on Earth, say that something might be straight up and down, but we are relating that to Earth's gravity. If you're in space, what is 'up'? Towards the Earth? Towards the Sun? Or towards somethig else? And that 'something else' might vary from time to time.
Earth is tilted on its axis, so it is never completely straight up and down. The tilt is about 23.5 degrees, which is what causes the seasons as different hemispheres receive more direct sunlight at different times of the year. This tilt remains relatively constant as Earth orbits the sun.
y axis
the x-axis is horizontal (left to right/ sideways) and the y-axis is vertical (straight up and down)
The earth orbits the sun. As the earth orbits the sun, the earth also spins on its axis. The axis goes through the north and south poles. The axis tilts in relationship to the earth's orbit. That tilt is called the tilt of the earth. If you have a globe mounted in a stand, that is why the globe is tilted instead of mounted straight up and down.
"Tilt on its axis" really doesn't mean anything. The Earth's axis of rotation is not "straight up and down" compared to the plane of its orbit around the sun. The axis makes an angle of about 66.5 degrees with the orbital plane, and the equator makes an angle of about 23.5 degrees with that plane. That's the reason for the changing length of days and nights during the year, and also for the seasons.
The sun does not go up and down. The earth rotates.
There is no fixed orientation in space, so the concept of "upside down" is relative. The Earth rotates on its axis, causing day and night, but there is no absolute "up" or "down" in space.
The north and the south pole would be frozen because they wouldn't get the heat that heat their getting now.Infact they will not even get heat
The Sun doesn't really go up and down. This is an APPARENT movement, caused by Earth's rotation around its axis.
