As Earth revolves around the Sun, how does its axis of rotation change relative to the Sun? How does this affect the seasons?

Answer 1

Lydia Allen

As earth goes round the Sun axis of rotation does not change.

It remains 23.4 degree. The angle at which Sun light strike Earths surface only change and that causes seasons.

The Earth's axis of rotation is tilted at an angle of about 23.5 degrees with respect to its orbital plane as it revolves around the Sun. This tilt results in different parts of the Earth receiving different amounts of sunlight throughout the year, which causes the seasons to change. Summer occurs when a hemisphere is tilted towards the Sun because the sunlight is more direct and concentrated, raising temperatures; winter occurs when a hemisphere is tilted away from the Sun because the sunlight is more indirect and dispersed, bringing about lower temperatures.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
