Sediment is _____________, __________________ pieces of material that come from ______________ or _____________ things. Water, _____________, and ________ can carry sediment and deposit it in _______________. Erosion What are the forces that break up and wear away all the rocks on Earth’s surface? 1. 2. 3. 4. 5. Erosion occurs when running________________________________________________ ___________________________________________________________ _________. Deposition Deposition is the process by which ________________ settles out of the _____________ or _____________ carrlying it. (The moving water or wind slows and deposits the sediment.) Different types of sediment are ______________________________________________ _______________________________. Compaction Before compaction occurs, the following steps take place: 1. Sediments fit _______________ _________________. 2. Thick layers of sediment __________________ _______. 3. These layers are heavy and _______________ down on the ______________ beneath them. 4. Then, __________________ occurs. Compaction is the process __________________________________________________. Cementation Cementation is the _______________________________________________________ ___________________________________________________. This means that while compaction is taking place, the minerals in the rock slowly dissove in the water and seep into the spaces between particles of sediment. This process often takes millions of years to work. Types of Sedimentary Rock There are three major groups of sedimentary rocks: 1. 2. 3. Clastic Rocks A clastic rock is a _________________________________________________________ _________________. Clastic rocks are grouped by the _________________________, or particles, of which they are mad. Shale feels smooth, and splits easily into flat pieces. Sketch rock: Sandstone forms from the sand on beaches, on the ocean floor, in riverbeds, and in sand dunes. Sandstone can easily ______________ water through these holes. Sketch rock: Conglomerate and Breccia contain a mixture of _____________________________ of different sizes. Conglomerate has ________________ edges. Breccia has fragments with ________________ edges. Organic Rocks Organic rock forms where _____________________________________________________ _________________________. “Organic” refers to __________________________________________________________. Two important organic rocks are ___________________ and ___________________________. Coal forms from the remains of____________________________________________ ______________________________. Limestone are formed by the hard _______________ of _______________________. Explain how limestone is formed. ______________________________________________________ ___________ ______________________________________________________ ___________ ______________________________________________________ ___________ ______________________________________________________ ___________ ______________________________________________________ ___________ Chemical Rocks Chemical rock forms when minerals that are dissolved ___________________________________ _______________________________________. They can also form from mineral deposits left when _________________ or _______________ evaporate. Halite and gypsum are both formed by evaporation. Uses of Sedimentary Rocks Sandstone and limestone are used as ________________________________. What is the White House in Washington, D.C. built out of?_________________________________. What is use for decorating or covering the outside walls of buildings? _________________________ ________________________ Limestone is used for __________________________________ and ___________________ _____________________.
