At a granular level‚ rocks are composed of grains of minerals‚ which‚ in turn‚ are homogeneous solids formed from a chemical compound that is arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO2); a compound of silicon and oxygen that forms 74.3% of the Earth’s crust. This material forms crystals with other

the Earth’s crust‚ rock is usually defined as a mixture of common minerals. Rocks can be hard or soft‚ as small as a grain or as large as a building. They have been an integral part of the history of mankind‚ first being used as tools for hunting and defense‚ and as a building materials to construct shelters and monuments. Combined with the effects of tectonics‚ weathering and vegetation‚ rocks define the natural landscapes we see around us. The minerals and metals we find in rocks are essential to

The rock cycle is very important to us because it explains the way the different types of rocks are formed on earth. Geologists classify rocks in three groups‚ depending on the Earth processes that made them. Some rocks are formed by heat and pressure. Other rocks are formed by weathering and erosion. The three rock groups are igneous‚ sedimentary‚ and metamorphic rocks. Igneous rocks are formed from melted rock that has cooled and solidified. They can form underground or above ground. Underground
