What do compaction and cementation of clastic sediments result in?
Compaction and cementation lead to lithification of sedimentary rocks. Compaction is the squeezing of sediments by the weight of the rocks and sediments above them. Cementation is when cement from fluids bind sediments together.
Which is the best description of what occurs during compaction?
happens when sediments are deeply buried, placing them under pressure because of the weight of overlying layers. This squashes the grains together more tightly.
What happens during compaction quizlet?
What happens during compaction? Compaction causes sediment particles to move closer together. Cementation causes sediment particles to stick to one another. You just studied 19 terms!
What process produces clastic sediments quizlet?
Weathering and erosion produce the clastic particles and dissolved ions that compose sediment.
What is the process of compaction and cementation?
1. Compaction occurs when the overlying sediments’ weight compacts the grains as tightly as possible. 2. Cementation is the process whereby dissolved minerals in the water between the grains crystallize cementing the grains together.
What rock is formed by compaction and cementation?
Sedimentary – A rock formed as a result of the weathering process, either by compaction and cementation of rock mineral fragments, or the precipitation of dissolved minerals.
What is sediment compaction?
In sedimentology, compaction is the process by which a sediment progressively loses its porosity due to the effects of pressure from loading. When a layer of sediment is originally deposited, it contains an open framework of particles with the pore space being usually filled with water.
How do sediments change into sedimentary rocks by compaction and cementation over time describe the geological processes involved?
Compaction and Cementation They are compacted, reducing the available pore space and expelling much of the pore-water. Dissolved minerals in the ground water precipitate (crystallize) from water in the pore spaces forming mineral crusts on the sedimentary grains, gradually cementing the sediments, thus forming a rock.
What is compaction and explain the process what is cementation and explain the process?
Compaction is the process in which sediment is squeezed and in which the size of the pore space between sediment grains is reduced by the weight and pressure of overlying layers. Cementation is the process in which sediments are glued together by minerals that are deposited by water.
Which process describes the changing of sediments into rock by compaction and cementation?
Which process describes the changing of sediments into rock by compaction and cementation? Explanation: Lithification is the processes where rock particles are compacted and cemented together from pressure to form sedimentary rock.
What process produces clastic sediments?
Four basic processes are involved in the formation of a clastic sedimentary rock: weathering (erosion)caused mainly by friction of waves, transportation where the sediment is carried along by a current, deposition and compaction where the sediment is squashed together to form a rock of this kind.
What process is used to form sedimentary rocks quizlet?
Terms in this set (20) Sedimentary rocks formed when pieces of other rocks or sediments are cemented together. Sedimentary rocks formed when minerals are dissolved in water and then the water evaporates.
Which is an example of a chemical sedimentary rock?
Examples include fossil limestone and coal. Chemical sedimentary rocks are formed from chemicals dissolved in water. Examples include rock salt and travertine (a type of limestone). Soil the top layer of Earth’s surface that supports plant growth.
Which is the best description of the rock cycle?
Rock cycle a continuous series of events through which a rock is transformed from one type to another. Sediment rock fragments that have been transported to a different location. Sedimentary rock rock formed from sediments, organic remains, or chemical precipitates. Clastic sedimentary rocks are composed of rock fragments cemented together.
Which is formed from the cooling of molten rock?
Igneous rock rock formed from the cooling of molten rock. Intrusive igneous rock – rock formed from the cooling of molten rock below Earth’s surface. Lava molten rock that has erupted onto Earth’s surface. Lithification the compaction and cementing of sediment into rock. Magma molten rock below Earth’s surface.
How are fossils formed in a sedimentary rock?
Fossils of sea creatures in sedimentary rocks indicate the historical presence of inland seas. A fossil that is a copy of an organism’s shape, formed when minerals seep into a mold. Classify to organize objects or events into groups based on common characteristics. Deposition the natural process of adding transported sediments to a landform.
