Land is the solid surface of Earth that is not permanently submerged in water. Most but not all land is situated at elevations above sea level (variable over geologic time frames) and consists mainly of crustal components such as rock, sand, soil, and sometimes ice.
The surface of the planet, where we live, is called the crust—it's actually a very thin layer, just 70 kilometres deep at its thickest point. The crust and the lithosphere below (the crust plus the upper mantle) is made of several 'tectonic plates'.
