what are the physical properties of sedimentary rocks?
15466
Sedimentary rocks contain rounded grains in layers. The oldest layers are at the bottom and the youngest layers are at the top. Sedimentary rocks may contain fossils of animals and plants trapped in the sediments as the rock was formed.

(f). Characteristics of Sedimentary Rocks. Sedimentary rocks can be categorized into three groups based on sediment type. Most sedimentary rocks are formed by the lithification of weathered rock debris that has been physically transported and deposited.

Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.

Sedimentary rocks form through the deposition of material at the Earth's surface and within bodies of water. ... These rocks are further classified by the size and composition of the clastic crystals included in the sedimentary rocks (most often quartz, feldspar, mica and clay).

Sedimentary rocks contain important information about the history of the Earth. They contain fossils, the preserved remains of ancient plants and animals. ... Sedimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperatures and pressures that do not destroy fossil remains.

Physical properties of soil include color, texture, structure, porosity, density, consistence, temperature, and air. Colors of soils vary widely and indicate such important properties as organic matter, water, and redox conditions.

Sedimentary rock's minerals are usually stable on surface conditions (otherwise they wouldn't have ... ... In that case, strongly cemented sedimentary rocks, specially sandstones, can be very resistant to erosion.

Sedimentary rocks are formed by weathered sediment using cementation or precipitation on Earth's surface . Metamorphic rocks are formed by changes of pressure and temperature within Earth's surface .

Clastic sedimentary rocks are dominated by components that have been transported as solid clasts (clay, silt, sand, etc.). In contrast, chemical and biochemical sedimentary rocks are dominated by components that have been transported as ions in solution (e.g., Na+, Ca2+, HCO3–, etc.).

Organic Sedimentary Rocks. Organic sedimentary rocks form from the accumulation and lithification of organic debris, such as leaves, roots, and other plant or animal material. Rocks that were once swampy sediments or peat beds contain carbon and are black, soft, and fossiliferous.

Detrital rocks are classified by their texture. The most important is particle size. What is texture- in a sedimentary rock sense? Texture for sedimentary rocks refers to the size, shape and and sorting of sediment particles.

Clastic sedimentary rocks are the result of weathering and erosion of source rocks, which turns them into pieces—clasts—of rocks and minerals. Once they become pieces, these clasts are free to move away from their source rock and they usually do.

Common chemical sedimentary rocks include oolitic limestone and rocks composed of evaporite minerals, such as halite (rock salt), sylvite, baryte and gypsum.

Clastic sedimentary rocks are made of sediments. The sediments differ in size. Chemical sedimentary rocks are made of minerals that precipitate from saline water.
