Some assume our planet’s changing distance from the sun causes the change in the seasons. That’s logical, but not the case for Earth. Instead, Earth has seasons because our planet’s axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth’s orbit around the sun.The tilt in the axis of the Earth is called its_____________ by scientists.

Answer:

Obliquity

Explanation:

Obliquity is usually defined as a term that is commonly used by the astronomers, and this refers to the axial tilt of the earth.

This obliquity also simply refers to the angle between the earth's rotation axis and the orbital plane of the earth. This value typically ranges between 21.8° and 24.4°. The earth at present is tilted at an angle of approximately 23.5°.

It is because of this tilt, the earth experiences the different seasons at different times, as well as the occurrence of day and night.
