This form of physical appearance is a result of how the crystals arrange during cooling. The sediment that rock is formed from is regularly coarser compared to other sedimentary rock with exception of breccias.

The grains of this rock are rounded and normally indicate that they have been carried more than angular grains thus differentiating them from other sedimentary rocks. This is basically an organic rock formed in shallow, warm and clear marine environs. In such environment, organisms extract ingredients necessary for the formation of calciium carbonate fro marine water. Marine contains skeletal debris of dead animals thus a source of minerals that accumulate to form limestone. However, some limestone may form from the process of precipitation whereby high temperatures cause rapid flow of calcium carbonate from marine water.

This rock has veins of minerals al through and its main constituents are mica and quartz. It is formed in environments such as high temperatures regions and areas experiencing considerable pressure to emit heat capable of melting rocks. Precisely, rocks under pressure are faulted and end up shearing resulting angular, fine-grained rock sediments.

As a result gneiss rock is formed. The process involves recrystallization. It involves rearrangement of fossilized materials such as grains of calcite, carbonate minerals Suzanne, It mainly constitutes the ocean floor.

It comprise of minerals such as, olivine and pyroxene. The cooling of the lava flow in a couple of days results in a solid rock, basalt Suzanne, It lacks minerals crystals.

It forms in areas where geological process result in volcanic eruptions and the chemical composition of minerals are appreciably rich in silica. Read all testimonials Do you want to get an.

The accumulation of minerals forms igneous rock. When the processes of vulcanicity, cooling and solidification of magma take place in the crust, the rocks formed are called intrusive igneous rocks.

Igneous rocks that are formed deep underground are called plutonic rocks and hypabyssal rocks are formed at intermediate depth below the earth surface. When the processes of vulcanicity, cooling and solidification of lava take place on the earth surface, extrusive igneous or volcanic rocks are formed. Any rocks exposed on the land surface are subject to exogenetic processes. They include commonly denudation weathering, erosion, transportation and deposition.

With the help of denudation agents, rocks are broken down and brought downslope. Rocks formed deep underground may also be exposed eventually after the overlying rocks are removed by denudation. Weathering, physical, chemical or biological, disintegrates or decomposes larger rocks into smaller fragments or sediments which are then eroded away from their original location.

When energy for transportation or erosion is lost, deposition takes place and sediments accumulate. Layers of sediments pile up by sedimentation. The rock fragments and grains are squeezed tightly during the process of compaction. Water in the spore spaces between the grains contains dissolved minerals like silica.

It helps glue the grains together. After compaction and cementation, loose sediments are transformed into solid rocks by lithification. The rocks formed are called sedimentary rocks. Sedimentary rocks can be formed chemically, organically and mechanically. For chemically formed sedimentary rocks, evaporation and precipitation of chemicals or minerals are involved. For organically formed sedimentary rocks, burying and compressing of dead living organisms are involved.

For mechanically formed sedimentary rocks, sorting process is often associated during deposition. Due to great heat, when sedimentary is melted, rocks become magma again and it may cools and solidifies to form igneous rocks.

Under great heat with melting or great pressure, igneous or sedimentary rocks could be metamorphosed by thermal metamorphism or dynamic metamorphism to form metamorphic rocks. Rising magma intruding into rock layers provide great heat to melt crystals which are then recrystallized into new rocks by thermal metamorphism. When rocks subduct into the asthenosphere, metamorphic rocks are melted to become magma and form igneous rocks or they are exposed for exogenetic processes to form sedimentary rocks.

The continuous cycle of rocks within the interior of the earth and on the earth's surface is known as the rock cycle. Geologists have recognized three different types of rocks that constantly change from one form to another through a number of different processes. One such rock is the igneous rock /5(3).

The Rock Cycle & Classification of Rocks The rock cycle is the formation, breakdown and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. The rock cycle is an illustration that is used to describe how the three rock types are related and how Earth processes change a rock from one type to another over time.

Rock cycle is the cycle of rock transformation which affects all rocks. The cycle involves all parts of the crust. When the rocks are subducted into the asthenosphere due to compression, the rocks melt into magma. The melting of rocks intensifies the pressure in the asthenosphere. Cracks develop.

Essay on The Hydrologic Cycle and Desert Landscapes - Introduction This paper is a two-part essay involving the hydrologic cycle and a desert landscape. First, the paper will discuss the hydrologic cycle and apply it to where I live, east Tennessee. Next, the paper will focus on a desert landscape. The rock cycle has only three types of rocks, igneous rock, sedimentary rock and metamorphic rock. Each of these rocks can form at the expense of the other. Igneous rocks are created when molten .
