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 rocks are igneous

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

A Genealogy of Rock Music Today‚ the term Rock Music brings about images of wild hotel parties‚ pyrotechnics‚ drugs‚ plane crashes and iconic frontmen.

First off you should know what a rock cycle is. The rock cycle is a fundamental concept in geology that describes the dynamic transitions through geologic time among the three main rock types: sedimentary‚ metamorphic‚ and igneous. Rocks make rocks. The cycle begins within the core of the earth. The molten rock in the core of the earth is called magma. Once the rock is forced to the earth’s lithosphere or crust‚ the molten rock becomes lava and thereby begins its long journey of development

Introduction Technology has evolved over millions of years to writing on rocks in caves to writing on a piece of paper made from trees. These improvements have impacted the world in positive and negative ways. Positive ways can be such as the telephone it has gone from being a brick to a thin and small which has helped for holding it and when you are ringing someone. A negative impact can be such as drugs because of the new technology people just walking around on the streets can create their own

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

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

in the rearrangement of molecules‚ but doesn’t affect their internal structures. When you make rock candy‚ you are creating a physical change. When sugar and water mix together‚ they are not forming a new substance‚ sugar dissolves‚ but it doesn’t disappear. So when you crystallize it‚ it still has the same chemical structure‚ the only thing that changed is the physical appearance. When we create the rock candy it will take about a week or more for it to fully form. While we do this project we hope
