Earth materials are the natural resources found on our planet, including rocks, minerals, soil, and water. These materials are essential for various processes, such as supporting plant life, providing construction resources, and forming landscapes. Each type of earth material has unique properties that determine its use and importance in the environment. Rocks are classified into three main types: igneous, sedimentary, and metamorphic. Minerals are the building blocks of rocks and have specific chemical compositions and structures. Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that support life. Understanding earth materials helps us manage resources and protect the environment.
