Land is the part of the surface of the earth that is dry, without any water covering the surface, and this may also be called the lithosphere. Land quotes show that this word can also refer to a country, such as the land of Tibet. Since land is dry it can be used to cultivate plants and raise animals, and there are many types of this surface. You will find hills, valleys, mountains, highly fertile plains, and many other varieties. The earth is covered with land that is mixed with bodies of water, such as lakes, springs, oceans, and other water areas. If there was no dry land on earth then the human species and other terrestrial animals would have difficulty surviving because we are not suited to live in water.
