PPT-Sedimentary Rocks

UNIT 5 What are Sediments Sediments are loose Earth materials unconsolidated materials such as sand which are transported by the action of water wind glacial ice and gravity These materials are . Sedimentary rocks cover ~ 75% of Earth’s surface. ~ 5 % (by volume) of Earth’s outer 10 miles. Contain evidence of past environments:. Important resource. Coal, oil, and other fossil fuels. Groundwater resources. . r. ocks. 97,3% of Hungary is . covered. . with. . some. . kind. . of . sediment. 75% of land surface on the earth is covered by thin veneer of sediments or sedimentary rocks.. Classification. . Timing the Geologic Record. . The Stratigraphic Record. Important Principles. Original horizontality—sediments were deposited originally as horizontal beds.. Lateral continuity—beds thin and pinch out laterally.. Did anyone ever have a rock collection?. Where do you think these rocks came from?. Do these rocks last forever?. THE ROCK CYCLE. Earth Science. The Rock Cycle. Rock Cycle – A series of processes that transform material from the stages of magma, igneous rock, sediment, sedimentary rock, or metamorphic rock to another.

Which of the following processes is NOT part of the rock cycle?. a. solidification. . b. chiseling. c. erosion. d. metamorphism. Sedimentary rocks form in 1 of 3 ways:. 1. . Clastic. Sedimentary Rocks- made of pieces and grains of other rocks. Material such as . sand . or . mud. -usually deposited in . water. Conglomerate sandstone. NAME THAT ROCK!. This rock is formed by cooling Magma. Igneous. This is formed underwater. It is made up of bits of shells and skeletons of sea animals. Sedimentary . This rock is formed by limestone that has been exposed to heat pressure.. Clastic. Sediments and Sedimentary Rocks. Clastic sediments are loose materials, however when these sediments under go lithification (. diagenesis. ), they form sedimentary rocks. . Clastic sedimentary rocks are also known as . BSc 4. th.

Clastic sedimentary rocks are accumulations of clasts: little pieces of broken rock which have been piled up and "lithified" by compaction and cementation.. Sediment . Texture. Sediment texture refers to the shape, size and three-dimensional arrangement of the particles . that make . up sediment or a sedimentary rock.. Textures can be . clastic or . crystalline. Do Now. 1.  What is an igneous rock?. 2. How do sedimentary rocks form?. Sedimentary Rocks -. are one of the three main rock types . A sedimentary rock can form one of three ways: . by the . deposition.
