Sedimentary Rock Various

Sedimentary rock batucollection.com is a type of rock that occurs due to the deposition of material resulting from erosion or dissolving. In other words, sedimentary rocks are rocks that come from pre-existing rocks. Sedimentary rocks make up only about 5% of the total volume of the earth’s crust and cover about 75% of the earth’s surface. In addition, about 80% of the continent’s surface is covered by sedimentary rocks.
In general, sedimentary rocks have bright or bright colors, white, yellow or light gray. Regarding color, this really depends on the composition of the materials that make it up. Referring to the website of the Merapi Volcano Museum, Sleman Regency, the following are types of sedimentary rocks according to the way they were formed.
1. Sedimentary rock from its depositional medium
According to the depositional medium, sedimentary rocks are classified into; aeris, glacial, aquatic, and marine sedimentary rocks. Aeris sedimentary rock is a sedimentary rock that originates from wind deposition, for example loss soil, tuff soil, and sandy soil in the desert. Whereas glacial sedimentary rocks originate from the deposition of ice/glaciers, for example moraine.
Aquatic sedimentary rock is a sedimentary rock that originates from the deposition of water. Examples that are widely known to the public include breccias, conglomerates, sandstone. Lastly, marine sedimentary rocks, are sedimentary rocks that originate from the deposition of sea water, for example limestone and rock salt.

2. Sedimentary rock from its place of deposition
Based on the place of deposition, sedimentary rocks are divided into teristic, limnic, continental, fluvial, and glacial sedimentary rocks. The type of sedimentary rock tertis is a rock whose place of deposition is on land. While the limnic sedimentary rocks come from deposition in the lake. For example, lake tuff and lake clay.
Types of continental sedimentary rocks deposited in the sea, for example, include loss soil, red soil, and desert soil. If it’s already on land, lakes and seas, then Fluvial sedimentary rocks come from deposition in rivers. Then glacial sedimentary rocks are sedimentary rocks that are deposited in places where there is ice or snow.

3. Sedimentary rocks from the way they are deposited
In addition to classification based on the medium and place of deposition, sedimentary rocks are also formed by depositional methods. First there is a sedimentary rock clastic, which is a sedimentary rock formed from weathering and erosion from other types of rock whose molecules then settle, combine and harden into one. Examples of types of sedimentary rocks clastic are breccias and sandstones.
There are also chemical sedimentary rocks that are formed from a chemical weathering process which then undergoes the separation of substance molecules. Separated substance molecules then unite with other substance molecules, and eventually form rock. Although there are also those who say that chemical sedimentary rock is a solution in water and is immediately deposited.
Finally, there is a type of sedimentary rock organic which is formed by a collection of microorganisms which then becomes rock. Some researchers say that organic sedimentary rocks are solutions in water which are then taken up by organisms, and through these organisms form organic sedimentary rocks.
