🔄 Earth's Rotation and Day-Night Cycles
This quiz explores how Earth's 24-hour axial rotation creates the day-night cycle we experience every day. You'll discover the terminator line that separates day from night, understand how time zones work around the globe, and learn why different places on Earth experience daylight and darkness at different times simultaneously. **What you'll learn:** - How Earth's rotation causes day and night - The concept and role of the terminator line - How time zones divide Earth into regions of similar local time - Why different locations experience opposite times of day at the same moment - The relationship between rotation speed and the 24-hour day
