Happy Birthday @USGS! ⛰️💧🪨🌋🗻
Got a a chance to hold a cast of the mandible or lower jaw of Spinosaurus at the new Sereno Fossil Lab of @UChicagoBSD. I keep forgetting how massive Spinosaurus was! #Dinosaurs #Paleontology #FossilFriday
Do other planets have leap years?
Yes! Leap years happen because a planet’s orbit around the Sun (year) and rotation on its axis (day) are not perfectly in line. This is true of almost every other planet in our solar system.
Are leap years really that important?
Leap years are important so that our calendar year matches the solar year. For example, say July is a warm, summer month where you live. If we never had leap years, in a few hundred years, July would take place in the cold winter months!
