The tilt of Earth's axis is called axial tilt or obliquity. This tilt is responsible for the changing seasons on Earth as different parts of the planet receive varying amounts of sunlight throughout the year.
the seasons either get colder or warmer, depending on the tilt of the axis.
The tilt of the Earth's axis.
23.5 degrees from the perpendicular.
The "tilt" is related to Earth's axis of rotation; both the axis of rotation and the tilt would be undefined if there were no rotation.
the seasons either get colder or warmer, depending on the tilt of the axis.
This tilt is what causes the seasons.
Mars is the planet that has a tilt axis similar to Earth's, with Mars having a tilt of about 25 degrees compared to Earth's 23.5 degrees. This similarity in tilt axis is one reason why Mars experiences seasons similar to Earth.
