If water is the transport medium of sediment, the grain size of sedimentary deposits most closely indicates the _____. a. geographic extent of the weathering source rock at outcrop b. average velocity of the water from the time of erosion until deposition c. velocity of the water at the moment the sediment settled to the bottom

The rock salt is mined, crushed to appropriate size, and usually applied to roads and highways without further processing. When applied dry, much of the salt can bounce off of the road or be scattered by the wind of passing traffic. If the salt is applied wet, more of it sticks to the road, and the loss of salt is reduced.

Clastic sedimentary rocks are subdivided on the basis of grain size. Secondary characteristics used to further distinguish clastic rocks are sorting, grain shape, and grain composition. ... Sorting is the extent to which the grains making up a clastic rock are all about the same size. A well-sorted ... gypsum limestone (Pellant p. 233-240 ...The dehydration process of gypsum rock was studied under concentrated solar energy by using a Fresnel lens with power density of 260 Wcm −2. Temperatures higher than 700˚C were attained for 1 min of solar exposure. The effect of grain size of sample and radiation exposure time on the formation of bassanite and anhydrite was studied by XRD.Sandstone is a clastic sedimentary rock comprised of sand-sized particles about .1 to .2 mm in size. It is usually tan, brown, or reddish in color, and often (but not always) displays noticeable layers. The sand grains are most often made of quartz, cemented together by calcite or silica.Final answer.

Figure 4.1.1 4.1. 1: Granite is a classic coarse-grained (phaneritic) intrusive igneous rock. The different colors are unique minerals. The black colors are likely two or three different minerals. If magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic.

For container plants, gypsum can be applied at 1 teaspoon for every 6 inches of pot diameter. Fun Fact. White Sands National Park has the world’s largest gypsum dunefield, an area of 275 square miles that contains an estimated 4.5 billion tons of gypsum. Only in extremely dry environments will soluble gypsum persist in sand-like dunes. In the rare cases where natural gypsum was used for tests, the gypsum was crushed, sieved and washed before compacting the fractions with a known grain size to form the test samples (De Meer and Spiers, 1995). The overall properties of the samples so obtained are expected to be closer to gypsum rock than to synthetic gypsum.30 seconds. 1 pt.
