The axis of the Earth is an imaginary line that passes through the North and South Poles. The Earth rotates around its axis. This axis is tilted at an angle of 23.5° relative to its orbital plane. This inclination of the axis plays a crucial role in causing seasons, variation in day and night lengths, and the changing altitude of the Sun in the sky throughout the year. Without this tilt, Earth would not experience the diverse seasonal patterns we observe today.
There are 10 Multiple Choice Questions (MCQs) on Inclination of the Earth’s Axis to recall the topic well.
