April 22nd is Earth Day, which is all about celebrating the planet we live on, sharing environmentally-conscious measures, and creating awareness of ecological issues. Below are some interesting facts about Earth from universetoday.com and livescience.com. Check them out and leave your own cool facts about the planet in the comments!
- The Earth isn’t a perfect sphere – as it spins, gravity pushes towards the centre of the planet, while a centrifugal force pushes outward, creating a “squished” sphere shape.
- The Earth is the only planet in the solar system with plate tectonics.
- The planet’s molten iron core creates a magnetic field that extends thousands of kilometers out from the Earth’s surface – scientists say without it, particles from the Sun’s solar wind would hit the Earth directly.
- At the equator you weigh less than at one of the poles – partly because gravity pushes extra ground and water into a bulge around its “waistline.”
- We all know Earth has one moon, but it also has two “co-orbital satellites” – they’re named 3753 Cruithne and 2002 AA29, which are…not good names.
- There are exploding lakes on Earth – in Africa there three crater lakes that sit above volcanic earth, creating a carbon dioxide-rich layer above the lakebed that can be released in an explosion.
