Answer:
By lithification
Explanation:
Sedimentary rocks (from Latin sedimentum, settlement) are formed by the precipitation and accumulation of mineral matter from a solution or by the compaction of plant and / or animal remains that consolidate into hard rocks. The sediments are deposited, one layer on the other, on the surface of the lithosphere at relatively low temperatures and pressures and can be composed of pre-existing rock fragments of different sizes, resistant minerals, remains of organisms and products of chemical reactions or evaporation .
A preexisting rock exposed on the surface of the earth goes through a Sedimentary Process (erosion or weathering, transport, deposit, compaction and diagenesis) with which it becomes a sedimentary rock; This transformation is known as lithification. Because sedimentary rocks are formed near or on the surface of the earth, their study informs us about the environment in which they were deposited, the type of transport agent and, sometimes, the origin from which the sediments were derived.
Sedimentary rocks are generally classified, according to the way in which they are produced, in detritic or clastic, and chemical or non-clastic; Within the latter, there is a subcategory known as biochemistry
<u>Detritical or Clastic sedimentary rocks</u>:
They are mechanical accumulations of particles or sediments of pre-existing rocks called "detritus" or "clasts" formed by weathering and surface erosion materials; these are transported and finally deposited, so they have a texture called clastic. These rocks are divided into a wide variety of types, which are characterized by the size of their constituent particles
Answer: I can promote environment conservation by making a small organization that promotes saving the ocean or forest. I can collect money and donate it towards a fund that promotes this as well.
Answer:
Sedimentary rocks are rocks composed of sediment. Sediment is deposited in a number of environments of deposition, by both moving air and moving water. Sedimentary rock identification is primarily based on composition. Texture will still be used but in a different sense than for igneous rocks.May 17, 2017
Explanation:
Answer:
b) It started as a fringing reef
Explanation:
When an island (basically a seamount or eroded volcano) that is formed on a caldera and which is surrounded by fringing reefs starts to sink or the sea level starts to rise gradually and engulf it , i.e. when the fringing reefs starts to grow it gradually forms an atoll .
It is basically a coral reef encircling a logoon . Coral starts to grow and build a fringing reef and later this barrier reef forms the atoll , which encircles a lagoon .
