What is the angle of Earth's axial tilt?

• A. 30°
• B. 15°
• C. 23.5°
• D. 45°

Answer: (C)

The angle of Earth's axial tilt is approximately 23.5 degrees. This tilt is crucial as it significantly influences the planet’s climate and seasons. Earth's axis is tilted relative to its orbital plane around the Sun, which leads to variations in sunlight intensity and duration at different latitudes throughout the year. This tilt is the reason for the changing seasons; as the Earth orbits the Sun, different areas receive varying amounts of sunlight due to this tilt. A tilt of around 23.5 degrees allows for the distinct seasonal changes we experience, such as summer and winter, as the hemisphere tilted towards the Sun experiences warmer temperatures, while the hemisphere tilted away experiences colder temperatures. This axial tilt is a fundamental aspect of Earth’s dynamics in relation to the Sun and is well-established in scientific literature, making 23.5 degrees the correct answer.
