Lithosphere Lithosphere of the earth mainly consists of rocks and soil. Rocks and soil both are natural resources. Rocks are made up of grains called minerals. One or more than one minerals are present in one kind of rock. Minerals can be seen or can't be seen with the naked eyes. Minerals are very important natural resource as they contain ores, from which metals and non-metals can be obtained profitably.
