Rock solid that occurs naturally. The mixture caused by the adhesion of ore together from one or more or a mixture of mineral and volcanic glass or mineral fossils. There are several characteristics or other solid rock. Different shapes out. Colorful varies. According to a resident , we can classify rocks on the Earth's crust Geological There are three of them, namely igneous rocks (Igneous Rocks) sedimentary rocks (Sedimentary Rocks) metamorphic (Metamorphic Rocks) , but the nature of the rocks in our country often characterize class (. bed) due to precipitation clearly. It has many names in the past these rocks as a rock, but today found that the sedimentary rock called it. It has been quite popular. The geologists found several times. Igneous or metamorphic rock that was to feature layers as well as layers of volcanic basalt. Or aging floor because the processing of gneiss. And in some sedimentary rocks were not a class, it is therefore the geological study of the country is trying to encourage college students and the general public to a sedimentary rock in the name of sedimentary rocks instead of sedimentary rock mass is solid. equipped with the same type of ore Or several species gathered in the wild. Since the composition of the earth's crust, mostly compound silicon dioxide (SiO2), so the crust is most often a silicate mineral family is also the family of carbonate minerals. The atmosphere is mostly carbon dioxide in Earth's past. Dissolved carbon dioxide into the atmosphere, rain water accumulated on the ground and ocean. Living organisms, nutrients and carbon to create the body. Some species of plankton build a silica shell. When die down as sediment deposition. Most of the Earth's crust is composed of rocks, minerals feldspar (Feldspar) is a group of minerals with over 50 per cent of the Earth's crust which is mainly composed of rocks of various kinds in the earth's crust. Feldspar is the main component is aluminum silicate. Many types of crystals When feldspar becomes eroded clay (Clay minerals) c Germain quartz (SiO2) is pure silica dioxide. A hexagonal crystal spiers. There are common in the continental crust But rare in the ocean crust and mantle. When the power flux decay becomes sand particles (Sand) c Germain Metz is very strong. Glass scratch marks mica (Mica) is a group of minerals which are crystalline thin. It is composed of aluminum silicate hydroxide. There are common in the continental crust Kingston has the same structure as clay (Clay minerals), a key component of soil Amritsar Frankfurt Bolton (Amphibole group) is like feldspar, but there are dark. It is composed of aluminum silicate hydroxide. Calcium, magnesium, iron or an alloy is available only in the continental crust. Examples of groups that แamฟiobl is common. Mineral hornblende Situated in granite rock Pine Road (Pyroxene group) are dark elements as magnesium and iron silicate much. Similar แamฟiobl But in the ocean crust is olivine (Olivine) are the main components are magnesium and iron silicates. There is very little on the crust Originated from the mantle below the crust family carbonate, calcite (Calcite) is calcium carbonate (CaCO3) is the main component of limestone and marble, dolomite (Dolomite), a mineral carbonate, a type of a manganese mixed CaMg (CO3) 2 mineral carbonates do. an effervescent reaction with acid to carbon dioxide.
