Approximately how many times greater is the amount of Earth’s surface that is covered by water compared to the amount of Earth’s surface that is covered by land? (The approximate total surface area of Earth is 5.1 × 108 km2 . All the salt water on Earth has an approximate surface area of 352,000,000 km2 , and all the freshwater on Earth has an approximate surface area of 9 × 106 km2.)
