Why can't we go to the bottom of the ocean?

“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don't notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth's atmosphere, the pressure would decrease to zero.

At what depth will water crush you?

This means we'd have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean. The 40% of non-water non-gaseous minerals and tissues such as salts, proteins, fats and lipids are virtually impossible to compress similar to water.

What would happen to you at the bottom of the Mariana Trench?

The pressure from the water would push in on the person's body, causing any space that's filled with air to collapse. (The air would be compressed.) So, the lungs would collapse. At the same time, the pressure from the water would push water into the mouth, filling the lungs back up again with water instead of air.

How old is the water we drink?

The water on our Earth today is the same water that's been here for nearly 5 billion years. So far, we haven't managed to create any new water, and just a tiny fraction of our water has managed to escape out into space. The only thing that changes is the form that water takes as it travels through the water cycle.
