Minerals and Rocks Minerals Minerals: Minerals are elements or compounds found in the earth. The elements or compounds are called minerals if they have five features. They are solids. They are formed naturally in the earth. They have the same chemical makeup throughout They are not alive or made of living things. They have definite arrangement of atoms. 3‚000 different minerals are found in the earth. Some are common but most are rare. Aluminum‚ quartz‚ feldspar

1. 1. Describe the Rock Cycle. Be sure to include the different rock types and processes that occur within the cycle. Consider a hypothetical granite (igneous rock) and describe three possible pathways through the cycle. The rock cycle is a model which is telling people that the changes of the rocks that take place on the earth. The changes show how each type of rock is formed. These all changes make their own type of rock base on the weathering‚ heat or pressure‚ etc.…all the rock made of

CheckPoint: Igneous Rock SCI245 July 20‚ 2011 CheckPoint: Igneous Rocks The answer to how igneous rocks are formed is given in their name; Igneous is Latin for “fire”. This basically means igneous rocks are cooled fire rocks from magma or lava‚ depending on where they cooled and formed. There are two categories of igneous rocks that also depend on where each was formed. Intrusive igneous rocks are igneous rocks that form when magma cools slowly and becomes solid underground. Extrusive igneous

Associate Level Material 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.

Geologic Setting The Wabigoon Subprovince is part of the Superior Province‚ an Archean age craton composed of E-NE trending granite-greenstone and metasedimentary terranes that span from western MN to northern Quebec. In Canada‚ the Neoarchean Wabigoon subprovince hosts numerous precious and base metal deposits‚ including the Sturgeon Lake VMS deposits and Rainy River and Hammond Reef gold deposits. Historically considered moderately to weakly prospective for hosting VMS deposits due to inferred

In the United States there are many different types of rock formations. For example‚ there is the Tuscarora formation and the Navajo sandstone. These two formations have many differences and similarities. Like their location which differs. The Tuscarora lies in the eastern coast‚ while the Navajo lies in the western coast. From the formations being wide and beautiful they both form many attractions! To begin with‚ the Navajo sandstone was deposited in the mid Jurassic period ( Herbert‚ 2015)
