A: Igneous rocks are one of the three types of rocks found on the earth; others are metamorphic and sed. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. They dont own the main structure of the building. Learn the definition of stratification and find what causes stratification. These layers can reveal what type of environment the rock was being formed in and how that environment changed. Scientists can use the arrangement of the layers to determine the relative ages of the layers. Stratification is the term used to describe items being composed of layers. These rocks are formed due to deposition of items such as sand and silt near the river beds. No direct relationship exists between the thickness and extent of strata and the rate of deposition or the time represented; for example, a stratum of limestone 2.5 cm (1 inch) thick may take longer to form than a stratum of sandstone 3 m (10 feet) in thickness. Origin of stratificationFirst recorded in 161020, stratification is from the Medieval Latin word strtifictin- (stem of strtificti). Stratification in volcanic rocks differs in some respects from that in sedimentary rocks. Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. Instructor: Ryan Hultzman.
