Graeme Bint The Pacific Ocean is 165.25 million square kilometres. It provides almost half of the Earth’s water area. It covers 30% of the worlds surface. The size of the Pacific Ocean is bigger than the total size of the landmass of all the continents together! It is the deepest ocean at an average depth of about 3,800 m! It houses the Marina Trench. I think it will manage to take a little extra sand!
I did post a reply as to whether the "Marina Trench" was at Port Hinchinbrook and await a response?
