Underwater, there are insane implosions at 25K feet below sea level. At that same depth on land, we have caves.
Why doesn’t the earth compress things like water does? Does gravity do different things to different materials?

Pressure out in the ocean or atmosphere has to do with how much stuff is above you weighing down on you. Imagine instead of water you’re in a giant ball pit. At the top of the ball put you’d feel normal, but if you sunk to the bottom of the ball pit with thousands of feet worth of plastic balls on top of you, you’d be crushed by the weight of all those plastic balls. It’s the same thing going on with water molecules in the ocean. It also happens with air molecules on land, but we don’t usually notice it because we are used to the pressure at ground level.
