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

Sedimentary Rocks Define 2 types of weathering? • Mechanical: breaking rocks into smaller chunks o Sediment: clasts (particles or sediment) • Chemical: dissolve mierals or change rock chemistry and make new minerals o Sediment: Ions in solution Which type would result in a conglomerate? • Mechanical. What are the compositions and depositional environments of Coal and Halite? • Coal: o Comp.: plant material o Dep. Environ.: Swamp • Halite: o Comp: NaCl o Dep. Environ.: desert‚

Describe the Rock Cycle. Be sure to include the different rock types and processes that occur within the cycle. Consider a hypothetical granite (igneous rock) and describe three possible pathways through the cycle. The rock cycle is a model which is telling people that the changes of the rocks that take place on the earth. The changes show how each type of rock is formed. These all changes make their own type of rock base on the weathering‚ heat or pressure‚ etc.…all the rock made of minerals

Amethyst Research Paper I went to the local flea market today and found a rock for sale. I decided to purchase the rock and bring it home to do a little research on it. After surfing the internet I discovered my find to be a mineral rock named‚ “amethyst.” I was interested in finding out where and how this mineral was formed. The more I searched‚ the more I encountered fascinating information. This is a small summary of what I learned. The physical characteristics of amethyst consist of

Sedimentary rocks in Pakistan range in age from Precambrian to Miocene i.e from oldest to youngest on the geological time scale form 542 million years to latest. Luckily for geoscientists all of them are exposed in different parts of the country. Lithologically they constitute sandstone‚ limestone‚ shale and mixed lithologies of them all. These rocks are exposed all along the mountain ranges from Islamabad in north to Karachi in the south. Igneous rocks are exposed north of Peshawar or only at

As all the students flooded into the classroom and started to unpack‚ the teacher‚ Mrs.Bentley‚ said‚ "Today you are going on a mini field trip to a park with Mrs.Crystal‚ who studies rocks and minerals! What you’re about to learn is a surprise!" The students cheered‚ wondering why they were going there. They gladly followed Mrs.Crystal out of the room and to the park nearby. Mrs. Crystal asked‚ "Do you know what inside a volcano?" Many hands shot up. She pointed to a girl. "Magma‚ and when it spews

Igneous Iggy was a shortstop playing for the Seattle Sedimentaries.. 2. He was a 10 year pro and hit 46 Rbi’s‚ and 15 Homeruns during his last season. 3. Over this time‚ Igneous Iggy experienced weathering and erosion‚ and compaction and cementation. 4. He also dramatically improved

Three Types of Rocks: There are three types of rocks and these three types of rocks are igneous‚ metamorphic‚ and sedimentary. These rocks all form differently. These rocks all can be made into another type of rock but they all are different and have probably been many different types of rocks. Igneous rocks form from cooling lava or magma. Igneous rocks that cool from lava have a much shorter cooling time than rocks that cool from magma‚ this is because magma is underneath the earths surface

Kit: Rocks Rocks are everywhere‚ they cover the whole earth. It is the foundation of the surface we live in. So‚ we basically live on rocks. They can be a part of a 5000 old year old ancient pyramid to the cement we walk on under our feet as we take a stroll on the street or in the park. When I started collecting rocks as a hobby a couple years ago‚ I found that there are many different types of rocks. Just not only the shape‚ texture‚ colour and size‚ but also where the rock originates
