On April 22, 1970, the first Earth Day was held as a way to give a voice to the growing environmental movement. In honor of the 50th Earth Day in 2020, we are focusing our Solar System Spotlight on our very own Planet Earth. Go back to the basics and see how much you know about our home planet .
The quiz was created from information found at the below NASA websites. To turn the quiz into an educational tool, we invite your students to read up on Earth’s planetary sciences first and then test their knowledge!
