Assignment: Sedimentary Rocks * Where do sedimentary rocks originate? Sedimentary rocks are the most common rock on earth. Sedimentary rocks form at‚ or very near‚ the Earth’s surface where rocks particles transported by wind‚ water and ice are deposited on dry land‚ on the beds of rivers and lakes and in marine environments: beaches‚ deltas and the sea (Sedimentary Rocks‚ 2001). The earth surface is constantly moving‚ materials are continually being deposited through various parts of the

Sedimentary rocks in Pakistan range in age from Precambrian to Miocene i.e from oldest to youngest on the geological time scale form 542 million years to latest. Luckily for geoscientists all of them are exposed in different parts of the country. Lithologically they constitute sandstone‚ limestone‚ shale and mixed lithologies of them all. These rocks are exposed all along the mountain ranges from Islamabad in north to Karachi in the south. Igneous rocks are exposed north of Peshawar or only at

Sedimentary rocks are rocks that are formed when particles of minerals or organic organisms are turned into solid rock due to pressure. There are three main types of sedimentary. The first is detrital rocks‚ which are formed by sediments from pre-existing sedimentary rocks that have been grated off from wind or water erosion then have found their way way to a water source such as a river‚ lake‚ or ocean. Once they have made it to the water source they are put under pressure due to the weight of

CLASSIFICATION OF SEDIMENTARY ROCK Sedimentary rocks are classified according to two(2) major classes known as: • Clastic (detrital) Sedimentary Rocks • Chemical Sedimentary Rocks Clastic (detrital) Sedimentary Rocks 1. Made up of mineral grains‚ fragments of other rocks (called lithic fragment)‚ shells and other inorganic(hard) of formally living organisms. 2. The clastic particles or grains in a sedimentary rocks are cemented together by mineral precipitates that formed during the

Displayed are a basic description of carbonate rocks‚ depositional environments‚ mineralogy‚ ancient and modern reefs‚ diagenesis‚ facies analysis‚ and classification. Most carbonate rock classification schemes take into account characteristics that may require intensive microscopic

Earth’s natural occurrences. From volcanoes to earthquakes plate tectonics play are large role. Another natural occurrence that is not is discussed as much as volcanoes and earthquakes is the formation of sedimentary rock. Plate tectonics also plays a major role in the formation of this type of rock. Plate tectonics is a term that is used to describe how the different plates that make up the Earth move and the reactions that occur as they are moving. Before explaining how plate tectonics are related

Three Types of Rocks: There are three types of rocks and these three types of rocks are igneous‚ metamorphic‚ and sedimentary. These rocks all form differently. These rocks all can be made into another type of rock but they all are different and have probably been many different types of rocks. Igneous rocks form from cooling lava or magma. Igneous rocks that cool from lava have a much shorter cooling time than rocks that cool from magma‚ this is because magma is underneath the earths surface

Comparison Worksheet Use the following table to compare extrusive and intrusive rocks. Describe and compare each type in at least 150 words. Extrusive Rock Intrusive Rock Extrusive rocks are also called volcanic rocks and extrusive rocks are formed on the earth’s surface. Extrusive rocks also form from magma‚ but a form of lava. Magma flows onto the earth’s surface by an eruption by a volcano. When the magma hits the earth’s surface‚ the magma turns into lava. Extrusive rocks are formed by
