Kit: Rocks Rocks are everywhere‚ they cover the whole earth. It is the foundation of the surface we live in. So‚ we basically live on rocks. They can be a part of a 5000 old year old ancient pyramid to the cement we walk on under our feet as we take a stroll on the street or in the park. When I started collecting rocks as a hobby a couple years ago‚ I found that there are many different types of rocks. Just not only the shape‚ texture‚ colour and size‚ but also where the rock originates

Rock Harmony (Andy Goldsworthy: “Rock Creation”) Richard Lipoczi Art 100 Jennifer Monroe 04/25/2013 Andy Goldsworthy is a British naturalist artist‚ mostly sculptor and photographer‚ creating in the twentieth and twenty-first centuries. He is still alive in these days. All his works draw on their themes from the nature: he uses only natural materials in their original environments to his works. He expresses his thoughts through transforming the natural matters to certain kinds of

crystalline. A crystalline has flat faces and smooth surfaces. Igneous rocks are formed from magma. If they are intrusive (plutonic)‚ they have large crystals and cooled slowly. If they are extrusive‚ they cool quickly‚ have fined grain. The scheme for igneous rock identification is based on texture‚ color‚ composition‚ and density. Sedimentary rocks are the 2nd step in the rock cycle. They are composed of bits and pieces of rock that have been watered by rain‚ water‚ and other things. They compress

A rock is another rocks raw materials‚ meaning rocks that dinosaurs used to step on‚ are what make up the rock we use to skip on the lake. The quick and simple way to answer how that could be true is‚ the rock cycle‚ but the rock cycle is actually very complex. It involves the formation and deterioration of rocks also it is connected with many of the other cycles in the earth. The rock cycle shows “one rock is the raw material for another” due to rocks going through three different phases: igneous

What Makes Rocks and Gems Different? By: Morgan Bellile Have you ever found a beautiful gem? Have you ever wondered what is in rocks? Did you know that red diamond is one of the most rare types of gems? Rocks and gems both have something in common‚ but have you ever wondered what makes rocks and gems different? Gems Gems are also known as precious stone‚ jewels‚ or just stone. What is a gemstone? A gemstone is a piece of mineral crystal‚ when the gem is cut and polished‚ it is normally used for

underlain by high grade metamorphic and igneous rocks of precambrian age. | National Assembly Complex | Generally trending NNESSW‚ these rocks consist of gneiss‚ migmatites and granites. A schist belt outcrops along the eastern margin of the area. The belt broadens southwards and attains a maximum development to the southeastern sector of the area where the topography is rugged and the relief is high. In general‚ the rocks are highly sheared (Kogbe‚ 1978). The rocks of the area can be divided

Write a 500- to 750-word explanation regarding the role of plate tectonics in the origin of igneous rocks. To begin‚ igneous rocks come from magma‚ and magma is related to plate tectonics. Magmas differ in composition‚ temperature and viscosity. This is a major identifier of igneous rocks‚ is that they were once molten and magma Plate tectonics are the theory that the Earth’s lithosphere‚ which is the outer rigid shell is composed of several different pieces‚ or “plates” that float on a ductile

Igneous rock is a Latin word meaning fire; these rocks are formed from volcanic activity. This rock is one of three types of rock including sedimentary and metamorphic rock. Igneous rock is formed from the cooling and solidification of lava or magma. Igneous rock can be formed with our without crystallization‚ below the surface as intrusive rocks or on the surface as extrusive rocks. Volcanic rocks also known as extrusive igneous rocks include all the products resulting from volcanic eruptions of

Rocks were not well exposed‚ most of which were covered by either soil or vegetation. And are also affected by weathering 1.3 OBJECTIVES The exercise was done by 300 level students which were grouped into five groups with three students in each group
