Sedimentary Rocks 5

Sedimentary Rocks 5-3 Question Answer What is the order that sedimentary rocks form. Compaction, Erosion, Cementation, Deposition. The order that sedimentary rock forms is: Erosion; Deposition; Compaction; Cementation. What is erosion? Wind or Rain wash away soil, sand or wears down rocks. What is Deposition? When wind or rain slows down the particles that wear away settle and build up. They get deposited in one location and build up. What is Compaction? It is when layers and layers of particles build up and over time become compacted by the weight of the layers. What is cementation? cementation is when dissolved minerals crystallize and glue the particles together. What is Clastic Rock? Clastic rock sedimentary roc that forms when rock fragments are squeezed together. What are examples of clastic rock? Clastic rock examples are sandstone, conglomerate rock, limestone made of dissolved calcite, Breccia Rock or shale. What is Organic Rock? Organic rock is sedimentary rock that forms from the remains of plants and animals. What are examples of Organic rock? Organic rock examples are: Limestone made form seashells, coal. What is Chemical Rock? Chemical rock is sedimentary rock that forms when minerals dissolved in a solution crystallize. What are examples of Chemical Rock? Chemical rock examples are rock salt or gypsum. What does erosion mean? Erosion is the process in which water or wind loosen and carry away rock fragments. What is clastic rock? Clastic rock is sedimentary rock that forms when rock fragments are squeezed together. What is sediment? Sediment are small, solid pieces of material from rocks or living things. What is cementation?(Hint: Cement) cementation is the process in which dissolved minerals crystallize and glue sediments together. What is organic rock? Organic rock is sedimentary rock that forms from the remains of plants and animals. What is compaction? Compaction is the process that presses sediment together. What is a chemical rock? A chemical rock is made up of sedimentary rock that forms when minerals dissolved in a s solution crystallize. What is Deposition? Deposition is the process by which sediment settles out of wind or water.
