crystalline. A crystalline has flat faces and smooth surfaces. Igneous rocks are formed from magma. If they are intrusive (plutonic)‚ they have large crystals and cooled slowly. If they are extrusive‚ they cool quickly‚ have fined grain. The scheme for igneous rock identification is based on texture‚ color‚ composition‚ and density. Sedimentary rocks are the 2nd step in the rock cycle. They are composed of bits and pieces of rock that have been watered by rain‚ water‚ and other things. They compress

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

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

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.

Sedimentary Rocks Dead Horse Point‚ Utah Dr. R. B. Schultz What are sedimentary rocks and what do they represent? Sedimentary rocks are those that represent the material record of environments in the form of rock layers or strata that once existed on earth. There are two (2) types of sedimentary rocks‚ based on their textures: Clastic (also called “Detrital”)-- form from deposition of solid grains; classified based on grain size: conglomerate‚ sandstone‚ and shale Chemical -- form from

types of rocks that can be found on the Earth are sedimentary rocks. There are two other kinds which are igneous and metamorphic rock. Sedimentary rocks cover about 75 to 85 % of the land on Earth. When pieces of rock or parts of once- living organisms or minerals from precipitation deposit and solidify on Earth’s surface they for sedimentary rocks. (Murck‚ et al.‚ 2008) In addition‚ the way the plate tectonics move‚ can significantly affect sedimentation and the formation of sedimentary rocks.
