Geology project part one

  1. 1. GEOLOGY PROJECT PART ONE Sara Huckabey
  2. 2. What is Geology• Geology is the science that pursues an understanding of planet Earth.• With this project we will focus on physical geology.• Physical geology examines the materials composing Earth and seeks to understand the many processes that operate beneath and upon its surface.• We will be examining three different types of rocks and their surroundings of where they were found.• The three types of rock will be Igneous, metamorphic, and sedimentary.
  3. 3. Igneous RocksIgneous Rocks form as molten rockcools and solidifies. A very famousformation of Igneous rocks is MountRushmore located in the Black Hills ofSouth Dakota. Igneous Rocks from intwo ways they either crystallize frommagma at depth or the lava solidifiesat the Earth’s surface.
  4. 4. Igneous RockWith rock I believe it could befeldspar, which falls in felsiccategory. Because of its lightcolor and looking up otherpictures of this type of rock itlead me in this direction. Itwas a pretty big rock andthough some parts aresmooth it also feels veryrough.
  5. 5. Location of Igneous Rock• This rock I found in another creek bed but by where I live in Bakersfield. I am pretty sure this is not where it originated from, but the rock was interesting compared to all of the other rocks that I found. It didn’t really belong, but this rock had an interesting color to it and it can be found in a lot of different areas. When I went to the creek it was dry so I was able to look around for a bit. In the summer time it is always full of water and everyone is down there cooling off. Creek might not be the right term, but I can’t think of what to call it.
  6. 6. Metamorphic RocksMetamorphic rocks are made fromalready existing igneous andsedimentary rocks. With metamorphicrocks they have a parent rock, whichis the rock they were created from. Ituses metamorphism which is theprocess that leads to the changes inthe texture and the chemicalcomposition of those rocks.
  7. 7. Metamorphic RockThis type of rock I want tosay is slate. Upon examiningthe rock it had very fine grainsize and had a smooth dullsurface. It also resemblesshale yet it just seems to be abit smoother. It’s basically aflat rock which also is acharacteristic. It is a blackcolor which means it containsorganic material.The second rock I believecould be quartzite. This rockwas very hard. It also kind ofhas pinkish lines if you get tolook at it closely. This rockhas medium grain size also.
  8. 8. Location of the Metamorphic Rocks• With the first rock that one I found on my many visits to the beach this summer. I traveled to Morro Bay with my family and found this rock. It wasn’t directly on the beach that I found it but when I was exploring some distance from the actual beach. I’ve seen rocks like this at this beach before and decided it might be something so I picked it up and used this information to help me identify the rock.• With the second rock when I was visiting my family that lives in Coalinga my sister and I went down to the creak and found some interesting rocks. This rock was sort of hard to identify so I am still not one hundred percent sure, but decided to give it my best guess. Creek beds are always interesting because you don’t know how long that rock has been there or if it originated from there or came down with a stream.
  9. 9. Sedimentary RocksThe word sedimentary comes fromthe Latin word sedimentum, whichmean to settle. Most of Earth’s solidsurface consists of sedimentary.Sedimentary rocks are the rocks thatcontain fossils, which makes themplay a big part with geologist.
  10. 10. Sedimentary RockWith this first rock I believeit can be sandstone. Whenyou examine it closely it hassand size grains over most ofthe rock. This rock is veryabundant after shale, in thesedimentary family of rocks.The second rock is what Ibelieve could be limestone.This rock is not smooth, butrough. It’s white in color andnot very big or the one Ifound is small. The locationof this rock was at Pismobeach. It was in these coolcaves.
  11. 11. Location of the Sedimentary Rocks• With the first rock, sandstone, I found this one on my way to Disneyland. We stopped by pyramid lake on the grapevine and I found a few rocks there. It was my first time stopping at pyramid lake so it was very interesting. We didn’t go too far down so I found this rock towards the top when you are looking down at the water.• The second rock I stated that I found it at Pismo beach. I took a lot of trips to the beach this year and found the rock near the beach. We walked down to the beach from our hotel and found all of these cool white caves. They were very interesting and I had never been to this area of the beach before. This was just a little piece that I found near some of the caves.
