Seasons will not change
Anyways,
you can't challenge nature
The earth is always tilted on its axis. It is about 23.5o
The Earth's axis is tilted by about 23.5 degrees.
The seasons are caused by the fact that the Earth's axis is tilted. As the Earth travels around the sun, the hemisphere that is tilted toward the sun changes. Whenever your hemisphere is pointed toward the sun, it is summer in your hemisphere.
The Earth spins about its axis. That defines the Earth's axis. It is the axis of spin that is tilted. If the Earth were not spinning it would not have an axis.
axis on what? the earth? if yes its tilted
In a way, the Earth's axis IS tilted on its side, that's why we have seasons.
if the earth wasn't on tilted on it's axis there wouldn't be any seasons
it is tilted on its axis
The Sun.
because of its axis and it rotates all around and every way around.
This is because (a) Earth revolves around the Sun, (b) Earth's axis is tilted, and (c) roughly speaking, and as a first approximation, Earth's axis maintains its direction in space.
The earth's axis of rotation is tilted relative to the earth's path around the sun. As a result we are tilted towards the sun in the summer and away from the sun in the winter.
