Revolution changes the season by how many miles per second?

Revolution changes the season by how many miles per second?

• A. 12 miles per second
• B. 24 miles per second
• C. 18 miles per second
• D. 30 miles per second

Answer: (C)

Earth’s revolution around the Sun occurs at about 18 miles per second. This is the orbital speed along the path Earth travels each year. The seasons, however, are driven mainly by the tilt of Earth’s axis relative to its orbit, which changes how sunlight hits different hemispheres over the year. The speed doesn’t cause seasonal changes; it just describes how fast Earth moves in its orbit. Since the actual orbital velocity is roughly 18 miles per second, that value is the best match. The other numbers don’t align with Earth's true orbital speed.
