Rocks are classified in order to communicate information about them. All classifications of limestones are arbitrary and they frequently overlap or do not fit ones particular needs. Since binocular microscopes or hand lenses are the tools that are commonly available to the explorationist‚ a practical classification should be based on descriptions using them. When these instruments are used‚ it is usually possible to identify the individual grains forming the rock. Thus most classifications require

School of Rock The ‘School of Rock’ is about an over confident guitarist Dewey Finn played by Jack Black. This film is written by Mike White‚ it is produced by Scott Rudin along with being directed by Richard Linklater. In this film Dewey Finn is a selfish so called “rock star”. He pushes his luck with the band and uses people to get what he wants or where he wants. A lot of the way through this film you come to terms with what makes the film what it is today‚ like lighting techniques‚ the uses

Metamorphic rocks are the transformation of the existing rocks‚ the protolith through the process of metamorphism. The Protoliths can be the igneous rock‚ sedimentary rock or any old metamorphic rock. Due to severe heat and pressure‚ the protolithis get various chemical or physical changes. These rocks create a huge part of the Earth’s crust and these can be classified by the mineral and chemical assemblage and by the textures. Examples of the metamorphic rocks are: slate‚ gneiss‚ schist‚ marble

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. Each group contains a collection of rock types that differ from each other on the basis of the size‚ shape and arrangement of mineral grains. Due to the driving

Formation of Rocks The three main ways rocks are formed: • Sedimentary rocks are formed through the gradual accumulation of sediment: for example‚ sand on a beach or mud on a river bed. As the sediment is buried it is compacted as more and more material is deposited on top. Eventually the sediment will become so dense that it is essentially rock. This process is known as lithification. • Igneous rocks are rocks which have crystallized from a melt or magma. The melt is made up of various components

About the Igneous rocks: The Igneous rocks are the oldest type of rocks among all. The word "Igneous" comes from a Greek word which means fire. In the deepest part of the Earth‚ the minerals are found in a liquid form‚ which is known as magma. When the magma pushes towards the surface of the Earth‚ it starts to get cool and converts into the solid Igneous rocks. The formation of Igneous Rocks: The Igneous rocks are known as the fire rocks and these are generally formed underground or above the

Igneous Rocks Igneous rocks originate from deep within the Earth’s crust. Igneous rocks (from the Greek word for fire) are formed when magma crystallizes and solidifies. An increase in temperature‚ a change in the composition‚ or decrease in the pressure can cause melting of these rocks in the mantle which form igneous rocks. The melt begins deep below the surface of the Earth close to active plate boundaries. As the temperate increases the rocks rise toward the surface. Igneous rocks are divided

* We should follow the rules so that we can maintain peace and organization within our society‚ economy‚ and even our country. Without rules no one would be able to work together. * Two different kinds of people can be heard to utter that question‚ "Why have rules?" One of them does not believe in rules; the other believes in rules and adds a few more words to the question‚ "Why have rules‚ if you are not going to enforce them?" I would like to examine both sides of this argument. Many people

Rocks and minerals are all around us. Earth’s crust and part of its mantle are made of rock. Rocks are made of minerals and have different properties. The properties of rocks include color‚ texture‚ luster‚ and hardness. We use rocks and minerals in many different ways. The steel in our buildings is made with iron‚ which is a mineral. The clay and glass used in our pottery and dishes are made of a mixture of rocks and minerals. We even need minerals to stay healthy‚ and we get them from a variety

Hand pollination (also called "mechanical pollination") is a technique used when natural‚ or open pollination is insufficient or undesirable. The most common techniques are for crops such as cucurbits‚ which may exhibit poor pollination by fruitabortion‚ fruit deformity or poor maturation. Hand-pollination is an option only on a small scale‚ but is a common technique by home and small market gardeners‚ involving the transfer of pollen with an artist’s brush or cotton swab from male to female flowers
