b/c new land is constantly being created by the clash of the tectonic plates and by upwelling of volcanic activity. Once all geological activity ceases (several billions of years in the future) then land might eventually erode away and the Earth's surface might briefly be covered completely with water. However, eventually all water will escape the planet's gravitational field and Earth will become, like Mars, a dead planet.
