Longitude Clues: Sunrise on the Equinox

Sunrise on the Equinox View animation as you work	Only on the equinox, locations at the same longitude experience sunrise at the same time. Students can estimate the longitude of each mystery site based on these key facts: The Earth turns to the east as it rotates. It spins 1 degree longitude every 4 minutes. The time between sunrise at the Prime Meridian and sunrise at a mystery site on the equinox reveals approximate longitude.
