Question

1. earth is tilted 23.5 degrees on its ______.*

options: side, hemisphere, axis, equator

Explanation:

The Earth's tilt of 23.5 degrees is relative to its rotational axis. The term "axis" refers to the imaginary line around which the Earth rotates. "Side" is incorrect as it's not a term for Earth's tilt reference. "Hemisphere" is a half of the Earth, not related to tilt. "Equator" is an imaginary line around the Earth's middle, not the tilt reference. So the correct term is "axis".

Answer:

C. axis
