The Mariana Trench in the Pacific Ocean is roughly $10\,\text{km}$ deep. If sea water is taken to be incompressible and to have a density of about $1020\,\text{kg m}^{-3}$, what is the approximate pressure at that depth?
- A$10^{5}\,\text{Pa}$
- B$10^{6}\,\text{Pa}$
- C$10^{7}\,\text{Pa}$
- D$10^{8}\,\text{Pa}$
