1. The world's largest fish is the whale shark, which may weigh several tons and grow to 60 feet in length -- that's as long as two school buses!

2. The deepest point in the ocean is the Marianas Trench in the Pacific Ocean which is 36,201 feet below sea level -- that's almost 7 miles down!

3. Although horseshoe crabs are called a "crab," the horseshoe crab is related to spiders and scorpions. And horseshoe crabs have been around for 250 million years, which makes them older than the dinosaurs!

4. The windiest place in the world is Mount Washington, New Hampshire, where a surface windspeed of 231 miles per hour was recorded on April 12, 1934.

5. The "Seven Seas" are the North and South Pacific, North and South Atlantic, Indian, Arctic and the Antarctic oceans.

8. The biggest known tornado in the U.S. was the Hallam, Nebraska F4 tornado of 22 May 2004 at nearly two and a half miles wide!

9.Thunder follows lightning -- a bolt of lightning superheats the air, causing a shock wave, and then a sound wave (thunder). So thunder really does follow lightning.
