The Earth's Crust
There are two large important areas on the surface of our planet: the continents, which constitute solid ground, and the seas and oceans. The continents and the ocean floor are formed of rocks. These rocks are made up of minerals. Rocks and minerals are very important. We extract metals, fuels and other natural materials from rocks for industry and construction. Natural resources, however, are limited. [...]
