Water. Most of the world is covered with water while the rest is covered by land. The largest masses of land in the world are called continents and there are 7. There are four different oceans; Pacific, Atlantic, Indian, and Arctic Ocean. :)
Water. The earths surface is mostly covered with water because 70% of earths surface is water rather than land...but only 0.5% of the earth is water compared to the rocky earth, so land is barely anything compared to water and rocks
