Some of the major end uses of graphite are in high temperature lubricants brushes for electrical motors friction materials battery and fuel cells and pencil lead While most graphite is formed through the metamorphism of organic material in rocks it also occurs in igneous rocks and is found as nodules inside of iron meteoritMar 04 32 Learn how igneous sedimentary and metamorphic rocks are formed We will also answer 1 what type of rock forms due to heating and cooling 2 how does each of the three rock

BACKGROUND A mineral is a naturally occurring inorganic element or compound with a definite chemical composition a characteristic crystalline structure and distinct chemical properties Minerals have to be naturally created or else they are classified as man made substanc Minerals are the building blocks of rocksSep 03 32 Created with CAST s UDL Book Builder Hello friends My name is Roxanne and I am going to tell you firsthand about my experiences through the process of the rock cycle This process takes a huge toll on my body and there are many changes that I will face as a rock

hematite Hematite sometimes spelled haematite and also known as kidney ore is a lustrous opaque blue black to silvery gray mineral often used in jewelry Hematite is iron oxide Fe 2 O 3 Hematite has a hardness of 65 and a specific gravity of 495 to 516 When powdered hematite is red when rubbed on a hard stone it leaves a red streakThe rock cycle is the set of processes by which Earth materials change from one form to another over time The concept of uniformitarianism which says that the same Earth processes at work today have occurred throughout geologic time helped develop the idea of the rock cycle in the s Processes in the rock cycle occur at many different rat

hematite Fe 2 O 3 Fe = iron O = oxygen there are two iron they formed On Earth an existing rock can undergo processes and become a different type of rock which means that rocks are recycled and that different rock types are all connected according to the rock cycle The concept map shows how the different rock families form In the map Rock Cycle the never ending rock changes that occur when a rock changes from one to another may take more than one path to create these changes Refer to the diagram on pages C52 and C53 in your book As rocks work through the rock cycle the materials that make them up

The Rock Cycle Rocks are constantly changing in what is called the rock cycle It takes millions of years for rocks to change Here is an example of the rock cycle describing how a rock can change from igneous to sedimentary to metamorphic over timeThe 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

We know that all three rock types can be turned into metamorphic rocks but all three types can also be changed through the rock cycle All rocks can be weathered and eroded into sediments which can then form sedimentary rock Rocks can also be completely melted into magma and become reincarnated as igneous rockThe rock cycle is an illustration that is used to explain how the three rock types are related to each other and how Earth processes change a rock from one type to another through geologic time Plate tectonic movement is responsible for the recycling of rock materials and is the driving force of the rock cycle

6 Rock Cycle The rock cycle is the process in which igneous sedimentary and metamorphic rocks are changed over time Igneous rocks are formed by volcanic activity Metamorphic rocks are igneous sedimentary or other metamorphic rocks that have been changed by heat pressure chemical means or a combination of all or some of the aboveJul 03 32 Rocks weather erode are deposited in the ocean are buried over time are raised by plate tectonics the surface is weathered and eroded leaving the sedimentary rock which then continues the rock cycle

The natural processes that take place on below and above the surface of the Earth move materials through a variety of cycles water nitrogen carbon and rock This activity is designed to teach your students about the rock cycle and the processes that move rocks through this cycleThe result is the creation of metamorphic rock Gemstones associated with metamorphic rock include beryl jade lapis lazuli turquoise spinel ruby sapphire and zircon Rocks and minerals are in a constant state of change which is referred to as the rock cycle Igneous rock can change into sedimentary or metamorphic rock
