Silting. Erosion.
These are likely loess deposits, formed from the accumulation of fine particles like silt and clay that have been carried by the wind from a distant source and then deposited over a wide area. Loess deposits are typically thick, homogeneous, and can be found in locations with strong prevailing winds and limited vegetation cover.
Bituminous coal is an organic sedimentary rock formed from the partially decayed remains of plants. Anthracite coal is considered metamorphic rock, and is derived from a bituminous coal protolith. Coal.
Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment often formed when weathering and erosion break down a rock into loose material in a source area. The material will then be transported from the source area to the area of deposition. The type of sediment that is transported to a place depends on the geology of the hinterland (the source area of the sediment). However, some sedimentary rocks, like evaporites, are composed of material that formed at the place of deposition. The nature of a sedimentary rock therefore not only depends on sediment supply, but also on the sedimentary depositional environment in which it formed.
Limestone deposits suggest that they were formed in a marine environment, typically in shallow, warm, and calm waters where the accumulation of calcium carbonate skeletons and shells of marine organisms was prevalent. The presence of fossils within limestone can indicate the past biodiversity and environmental conditions of the area where the deposits formed. Additionally, the purity and composition of the limestone can provide clues about the depositional processes and the source of the materials.
Yes, the organic sedimentary rock you are referring to is most likely coal. Coal is formed from the remains of plants that lived and died millions of years ago. It is a major source of energy used to generate electricity in power plants.
Erosion transports sediments from the original source through processes like wind, water, or ice. As the sediments are eroded, they are carried away and eventually deposited in a new location, forming sedimentary deposits.

Soil can be formed from the erosion and deposition of any kind of rock: igneous, sedimentary, or metamorphic.

The best sediment sorting description refers to the process by which sediments are separated according to their size and weight. During sediment sorting, finer particles are typically carried further by water or wind, while larger particles settle out closer to their source. This sorting process helps to create distinct layers in sedimentary deposits.

You answer it.
Coal is a sedimentary rock that forms from the remains of plants that lived in swampy environments millions of years ago. It is typically found in underground deposits known as coal seams or coal beds. Coal can be mined from these deposits to be used as a source of energy.

A sedimentary rock is a rock formed at or near the Earth's surface by the accumulation and lithification of fragments of preexisting rocks or by precipitation from solution at normal surface temperatures. Sedimentary rocks can be formed only where sediments are deposited long enough to become compacted and cemented into hard beds or strata. They are the most common rocks exposed on the Earth's surface but are only a minor constituent of the entire crust. Their defining characteristic is that they are formed in layers. Each layer has features that reflect the conditions during deposition, the nature of the source material (and, often, the organisms present), and the means of transport.

Sedimentary rocks made of weathered rock fragments are called clastic sedimentary rocks. These rocks are formed from the accumulation and cementation of fragments that have been weathered, eroded, and transported from their original source. Examples include sandstone, shale, and conglomerate.
