Explanation:
The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.
It would lower the pH, raise the acidity of the water, and it would kill off a lot of marine life if it got too high. As species begin to die their predators follow, and this could cause mass extinction.
