2. Sediment analysis is an important tool for understanding the composition and characteristics of a body of water. Describe the techniques used to analyze sediment samples, including grain size analysis and microscopic examination. How can this information be used to inform environmental management and conversation efforts?


Answer:

Sediment analysis involves examining sediment samples to understand their composition, structure, and characteristics. This analysis is important for understanding the quality of water bodies, as sediments can contain pollutants and other contaminants that can have negative impacts on aquatic life and human health.

There are several techniques used to analyze sediment samples, including grain size analysis and microscopic examination.

Grain size analysis is used to determine the distribution of particle sizes within a sediment sample. This technique involves separating the sediment into various size fractions, typically using sieves of different mesh sizes. The weight of each size fraction is then measured and used to calculate the percentage of the sample that falls within each size range. Grain size analysis can provide valuable information on sediment transport, sedimentation rates, and the origin of sediment particles.

Microscopic examination involves examining sediment samples under a microscope to identify the presence of organisms, minerals, and other particles. This technique can provide information on the ecological health of a water body, as well as the potential sources of pollutants and other contaminants.

The information obtained from sediment analysis can be used to inform environmental management and conservation efforts in several ways. For example, grain size analysis can help identify areas where sediment is eroding or accumulating, allowing for targeted erosion control measures or sediment removal efforts. Microscopic examination can provide information on the types and levels of pollutants present in sediments, which can inform decisions on remediation efforts and pollution prevention measures. Additionally, sediment analysis can help identify areas of high biological activity, which can inform decisions on habitat conservation and restoration efforts.

In summary, sediment analysis is an important tool for understanding the quality of water bodies and can provide valuable information for environmental management and conservation efforts. Grain size analysis and microscopic examination are two key techniques used in sediment analysis, providing insights into sediment transport, pollutant levels, and biological activity.

Answer:

Grain size analysis is an important sediment analysis technique that allows scientists to determine the size and distribution of sediments in a specific area. This type of analysis involves collecting sediment samples from an area, then sieving and counting them into ranges of grain sizes. Knowing the size and distribution of the sediments can provide scientists with information about the type of sediment deposited in the area and its geologic history.

Microscopic examinations are also used to analyze sediment samples to identify its composition and characteristics. This type of analysis involves using a microscope to examine the individual grains in the sample. By looking at the shapes, sizes, and striations on the grains, scientists can identify the type of sediment present, where and when it was deposited, and what environment it was transported in.

The analysis of sediment samples can provide important information about the environment and important clues about its past and present. This type of information can help environmental management and conservation efforts by informing best practices for protecting the environment, monitoring water quality, and restoring habitats. For example, if scientists discover that the sediment in a certain area is eroding at an uncontrolled rate, they may suggest actions such as dredging to restore the environment, or establishing buffer zones to protect the sediment from further erosion. Additionally, understanding the composition of the sediment can help inform design strategies for regional planning and coastal development.

3. rice husk from grains is it picking winnowing or sedimentation​


winnowing? I'm not sure tho.


4. why do shapes and sizes of the sediments in sedimentary rock differ?​


Explanation:

Particle size is an important textural parameter of clastic rocks because it supplies information on the conditions of transportation, sorting, and deposition of the sediment and provides some clues to the history of events that occurred at the depositional site prior to final induration. Determining the sizes of the discrete particles that constitute a sedimentary rock can be difficult, particularly if the rock is firmly indurated (cemented, compacted, and lithified). Various methods of measuring grain-size distribution have been devised; likewise several different grade-size schemes exist.


5. Compacted sediments classified by size​


Compacted sediments classified by size

The Udden-Wentworth grain-size scale is used by geologists who research sediments and sedimentary rocks to describe the sizes of the grains in these materials. Here are the six basic categories for grain size; five of them include subdivisions, with clay being the exception. Every subsequent subcategory has diameter restrictions that are twice as large as the category below it.

Generally speaking, a boulder is heavier and larger than a toaster. The size of a boulder has no upper limit. A little cobble may be held with one hand, but a huge one requires two. A pebble is anything that is simple to throw. Granules, which are the smallest ones, are gravel-sized, yet you could still toss one. You can't, however, truly toss a single sand grain.

Sand has a thickness range of 2 mm to 0.063 mm, and its primary trait is that even the smallest sand grains feel "sandy" or gritty when touched. Silt's tiny size makes it impossible to see individual grains, and unlike sand, which feels gritty in your mouth but smooth to the touch, silt feels smooth to the touch. Since clay is so tiny, even in your tongue it feels smooth.

8. compacted sediments classifiedbby size what kind of rocks​


Answer:

Sedimentary rocks are classified based on how they form and on the size of the sediments, if they are clastic. Clastic sedimentary rocks are formed from rock fragments, or clasts; chemical sedimentary rocks precipitate from fluids; and biochemical sedimentary rocks form as precipitation from living organisms.


9. the grain size of a sandstone is large that of a shale​


Explanation:

Shale is an easily broken, fine-grained sedimentary rock composed of clastic grains with sizes <0.0625 mm, clay, and organic matter with shaley or thinly laminar bedding (Table 10.2). Shale is widespread in nature, making up about 55% of sedimentary rocks.


10. a process where minerals deposited from water in the spaces between the sediment grains gradually cements them together.


Answer:

Cementation

Explanation:

Cementation is a process by which minerals precipitate from pore fluids and bind individual grains together to form a rock. The cement may be quartz, calcite, hematite, etc. The process of converting sediments into rocks is termed lithification.

Answer:

it is called : comminution

Answer with Explanation:

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. ... Within industrial uses, the purpose of comminution is to reduce the size and to increase the surface area of solids.


23. Differ from one another depending on the kind,size,and color of their sediments?​


Answer:

Sedimentary rocks

Explanation:

The size of sediment is defined by the size of the particles that make up the sediment. The largest sediment size is called a boulder. Boulders have a diameter that is larger than 256 millimeters (about 10 inches). Cobbles are the next largest sediment, they are 64 - 256 mm in diameter (about 3-10 inches). Pebbles are next in size and are 4-64 mm in diameter (about 1/6-3 inches). The next sizes of sediments are very small, granules are 2-4 mm, sand 1/16-2mm, silt 1/256-1/16 mm, and the smallest sediment size is clay which is less than 1/256 of a millimeter in diameter.

Sedimentary rocks are formed in three ways from these different sized sediments.

A sedimentary rock is a layered rock that is formed from the compaction, cementation, and the recrystallization of sediments.


24. What is grain size reduction. elaborate?


Answer:

Decreasing grain size decreases the amount of possible pile up at the boundary, increasing the amount of applied stress necessary to move a dislocation across a grain boundary. ... Grain sizes can range from about 100 μm (0.0039 in) (large grains) to 1 μm (3.9×10−5 in) (small grains).
