The following is a list of rock types recognized by petrologists.There is no agreed number of specific types of rocks. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe rock types.
Photographs and information for a large collection of igneous, metamorphic and sedimentary rocks. Geology.com
Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic.Igneous rock is formed through the cooling and solidification of magma or lava.
The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock.
The three main types of geological rocks are described. They are...

The Rock Gallery contains pictures and descriptions of common igneous metamorphic sedimentary rock. The igneous rocks are listed at the top of the page followed by metamorphic and sedimentary rocks.
Igneous, Sedimentary vs Metamorphic Rocks. The main difference between Igneous, Sedimentary and Metamorphic rocks, is the way that they are formed, and their various textures.
Feb 20, 2016 · The Rock Cycle is Earth's great recycling process where igneous, metamorphic, and sedimentary rocks can all be derived from and form one another
The three types of rocks—igneous, sedimentary, and metamorphic—are all subject to processes that change one rock type into another. The images below show several types of rocks undergoing these processes.
List. Sorted by name; initial letter means Igneous, Sedimentary or Metamorphic rocks.. A I Andesite – an intermediate volcanic rock M Anthracite – a form of hard coal B S Banded iron formation – a fine grained chemical sedimentary rock composed of iron oxide minerals
Types of Rocks Rocks are not all the same! The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed.
Metamorphic rocks are one of the three types of rock classifications, the other two being igneous and sedimentary.
A few days ago I shared the Rocks and Minerals Packet I made for ED (which is also free). I wanted to spend more time on the three types of rocks–igneous, sedimentary and metamorphic rocks.
THE EARTH'S CRUST The whole earth is made of rocks & minerals. Inside the earth, there is a liquid core of molten rock and on the outside, there is a hard crust.
Oct 31, 2012 · We bet you thought that rocks are just rocks, but the truth is there are three different kinds of rocks. Learn the differences between sedimentary, metamorphic and igneous rocks.
Igneous, from the root word ignite which means to catch fire! Did you know how an igneous rock is formed? Extremely hot molten rock from the deep recesses of the earth makes its way out and literally ignites everything it comes in contact with, once the liquid cools down, an igneous rock is formed.
What are the 3 basic types of rocks? Just as any person can be put into one of two main categories of human being, all rocks can be put into one of three fundamentally different types of rocks.
Peridotite is an intrusive igneous rock with an ultramafic composition. Many Types of Peridotite. The peridotite "family" contains a number of different intrusive igneous rocks.
I had lots of fun with this song in my concerts this summer! You can print out the pages with the names of the rocks, and use them to explain the following:
In this lesson, we will discuss the three main types of rocks and how they are formed. The lesson also gives an introduction into how matter locked...
Metamorphism tends in some degree to reverse the geochemical differentiation of the elements produced by igneous and sedimentary processes. In general, metamorphism promotes a more uniform distribution of the elements and tends to erase compositional differences within large rock masses.
There are three important Rock Types – Igneous, Sedimentary and Metamorphic Rocks. We will study them in detail. You must first know about volcanism
Igneous rock is in the making as lava pours down a well-developed lava channel near a series of erupting vents on the northeast rift zone of Mauna Loa Volcano.
