Facts about the World

The world is full of surprising facts: Earth isn't perfectly round, its magnetic poles wander, and only a tiny fraction of its water is accessible fresh water, with most locked in ice. Physically, the Mariana Trench is the deepest point, while the Amazon River is the longest. Some animals have unique traits, like Acacia trees communicating with gasses, and the official animal of Scotland is the unicorn.

• Moon: The Moon is slowly drifting away from Earth.
