Red Rocket Readers: Advanced Fluency 4 Non-Fiction Set A: Undersea Exploration (Reading Level 29/F&P Level U), 1st edition

The deep ocean has no light, and the water pressure is so great it can shatter human bones! But that hasn’t stopped explorers and inventors developing and improving underwater machines and equipment that have eventually taken people to the deepest places on Earth. Why? To see what’s there, of course.
