Chapter 3 Vocabulary Rocks Rock Grain Texture Sediment Rock cycle Extrusive Volcanic glass Instrusive Compaction Cementation Clastic Clasts Chemical rocks Biochemical rocks Metamorphanism Plastic deformation Foliated rocks Nonfoliated rocks Contact metamorphism Regional Metamorphism Natural, solid mixture of minerals or grains. Fragments that make up the rocks The grain size and the way grains fit together Rock material that forms where rocks are broken down into smaller pieces or dissolved in water as rocks erode Series of processes that change one type of rock into another type of rock Volcanic material erupts and cools and crystallizes on Earth’s surface Rock that forms when lava forms too quickly to form crystals Magma cools underground The weight from the layers of sediment forces out fluids and decreases the space between grains When minerals dissolved in water crystallize between sediment grains Sedimentary rocks that are made up of broken pieces of minerals and rock fragments Broken pieces of minerals and rock in a clastic rock When minerals crystallize directly from water. Sedimentary rock that was formed by organisms or contains the remains of organisms. Any process that affects the structure or composition of a rock in a solid state as a result of changes in temperature, pressure, or the addition or chemical fluids. Permanent change in shape by ending and folding Contain parallel layers of flat and elongated minerals. Metamorphic rocks that have mineral grains with a random, interlocking texture Magma comes in contact with existing rock, and its thermal energy and gasses interact with the surrounding rock, forming new metamorphic rock. The formation of metamorphic bodies that are hundreds of square kilometers in size Quiz: FRIDAY!!! STUDY UP!!!
