The greatest ocean depths on Earth are found in the Marianas Trench near the Philippines. Calculate the pressure due to the ocean at the bottom of this trench, given its depth is 11. 0 km and assuming the density of seawater is constant all the way down. 1. 09×10^3 atm 2. 00×10^3 atm 9. 09×10^3 atm 4. 09×10^3 atm
