Rock cycle refers to the process of change and the rotation of the stone, akni. Metamorphic rocks and sedimentary stone can change from one type to another type of stone by thermal pressure. Tending to push borne and mess The current stone recurrence There is a new rock occurs all the time in the world or the skin deep down under the Earth's crust, such as Nile River mouth area. In Egypt, where flow convergence Mediterranean sea sediment t fold come mess. Over time, these sediments became the floor stone floor remaining vestiges indicate environmental conditions during the 20th century, or salvage fossils found, saraburi province bar lapakarang. There is an element of limestone, which in the past, the creatures living in the sea before. -To measure the age of radioactive Scientists discover how to find relics from the stone age to measure radioactive. Radioactive atoms of the element by some species within the rocks to decay any time by measuring the quantity of such atoms remaining in the stone can be calculated the age of the rocks. -Detection of fossil animal genera, such as the age of the dinosaurs extinct then ever alive when approximately 245-65 million years ago, the stone floor, so that the remaining dinosaur bones were found to have occurred during this time. Those who study fossils are traces of people first is William Smith (1769-1839). A British engineer is the "father of modern geology" believe that the remains of stone age fossils chest, delete different types of floor. The rocks are divided into 3 categories:1. Stone akni Caused by the solidification of molten magma beneath the Earth's crust, lava, and they are divided into 2.1.) caused by Magma (lava) cool and crystallize quickly became a small mineral crystals is called the stone details output or volcanic stone akni akni (Vocalnic or Extrusive Rocks) on the Earth's crust or surface such as stone (Rhyolite) highlighted Rio basalt (Basalt), etc.
