At a granular level‚ rocks are composed of grains of minerals‚ which‚ in turn‚ are homogeneous solids formed from a chemical compound that is arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO2); a compound of silicon and oxygen that forms 74.3% of the Earth’s crust. This material forms crystals with other

Mount Fuji Imagine arriving home from a very long trip‚ waiting to go relax and sleep in your precious home. When the home sweet home you realize is covered in volcanic ash and half of your house is destroyed by lava.

also traded to the Olmec people. Obsidian was used to make knives‚ pottery and even a "grating device used to process manioc" (Evans 2004:135). Raw materials like basalt and rubber were also traded in the region. The Olmec artist was a skilled member of society. Amongst the Olmec art forms‚ sculpture was very important. The Basalt that was imported into San Lorenzo was often used for Monumental size sculptures. The Olmec colossal heads are famous pieces of early formative art work; some standing

traditional places in Jeju Island. I have been to Jeju Island with my parents in December‚ 2010. I could not see any water activities‚ but we had good time. We have visited to Jeju’s traditional house‚ waterfalls‚ and columnar jointing which is made of basalt. Jeju is one of Korean Republic’s cities‚ but they have their own different culture. People in Jeju are proud of their unique culture. I think it is the reason why Koreans also enjoy when they go to Jeju Island. The third difference between the

Composite Materials A composite is a combination of two or more materials bonded together to gain some overall necessary goods. Types of composite include: laminated materials fibre composites particle composites. A laminate contains thin pieces of material fused together. Common examples are plywood and car windscreens. Wood is durable when exposed to a ductile force equivalent to its grain‚ but if the strength is across the particle it splits simply. A windscreen is made in a parallel way; two

The development of the theory of plate tectonics from Continental Drift to the present The theory of continental drift first came to be in 1915 when Alfred Wegener first proposed his belief that 300 billion years ago there was one single supercontinent‚ Pangaea. At the time‚ most did not believe it was true as he had no proof or idea of how the masses of land would move. However‚ new evidence was put forward over time that fit with Wegener’s beliefs. The first key piece of evidence is the shape

Political power‚ religion‚ and economy are the three basic components that determine how any type of chiefdom‚ state‚ or even empire is to prosper and properly run. Dating back to before 5000 BC the first settlement of Ubaid in southern Mesopotamia used these tools to run a functional community. These traits showed their importance by how they were carried all the way on to the first civilization of Olmec in Mesoamerica. Although the Olmecs revitalized certain aspects of what a perfect political
