In geology, rock or stone is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock.
Rocks have been used by mankind throughout history. From the Stone Age, rocks have been used for tools. The minerals and metals found in rocks have been essential to human civilization.
Three major groups of rocks are defined: igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is an essential component of geology.
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 compounds in the rock. The proportion of silica in rocks and minerals is a major factor in determining their name and properties.
Wikipedia (i/ˌwɪkᵻˈpiːdiə/ or
i/ˌwɪkiˈpiːdiə/ WIK-i-PEE-dee-ə) is a free-access, free-content Internet encyclopedia, supported and hosted by the non-profit Wikimedia Foundation. Those who can access the site can edit most of its articles. Wikipedia is ranked among the ten most popular websites, and constitutes the Internet's largest and most popular general reference work.
Jimmy Wales and Larry Sanger launched Wikipedia on January 15, 2001. Sanger coined its name, a portmanteau of wiki and encyclopedia. Initially only in English, Wikipedia quickly became multilingual as it developed similar versions in other languages, which differ in content and in editing practices. The English Wikipedia is now one of 291 Wikipedia editions and is the largest with 5,081,662 articles (having reached 5,000,000 articles in November 2015). There is a grand total, including all Wikipedias, of over 38 million articles in over 250 different languages. As of February 2014, it had 18 billion page views and nearly 500 million unique visitors each month.

A study guide made for the students of Fleming College in Lindsay Ontario Canada and anybody else who might find it useful. If you like this video check out my channel for a full feature video of a limestone rock quarry, how it operates, and how it is being rehabilitated. I am trying to educate you about more than just rocks and minerals. Research "Agenda 21" and find out the U.N.'s real plan for "sustainable developement". PLEASE CHECK OUT MY ENTIRE FAVORITES LIST!!!
Rocks are awesome! They can be found everywhere on earth and come in many different shapes, forms, and textures. There are three main types of rock: igneous, sedimentary, and metamorphic. Learn more about these types of rock, how they are formed, some examples of each type, and how the rock cycle works to change one type of rock into another.

003 - Geology In this video Paul Andersen explains how rock is formed and changed on the planet. The video begins with a brief description of rocks, minerals, and the rock cycle. Plate tectonics is used to describe structure near plate boundaries. Hot spots and natural hazards (like volcanos, earthquake, and tsunamis) are included. Do you speak another language?

This documentation serves as a record of the flora and fauna species inhabiting the ecosystems during the specific time frame and can be used in the future as a reference to how the ecosystems are constantly evolving as well as the affects on them by anthropogenic activities. These ecosystem videos, audio recordings, and photographs are presented in a format so they may be used for educational instruction and testing purposes as well as scientific study of the ecosystems, therefore narrations have been left out and classical music used in the background when no natural sound is available, ultimately leaving the videos for self interpret...
