Accepted Answer

Scientists use submarines and robots to explore the deep ocean. These machines can handle high pressure and send back pictures and data.

Question 18

What is the Mariana Trench?

Accepted Answer

The Mariana Trench is the deepest part of the ocean. It's so deep that you could fit Mount Everest inside and it would still be underwater!

Question 19
