Sediment - Wikipedia
Seas, oceans, and lakes accumulate sediment over time. The sediment can consist of terrigenous material, which originates on land, but may be deposited in either terrestrial, marine, or lacustrine (lake) environments, or of sediments (often biological) originating in …
Sedimentary rock | Definition, Formation, Examples,
sedimentary rock, rock formed at or near Earth’s surface by the accumulation and lithification of sediment (detrital rock) or by the precipitation from solution at normal surface temperatures (chemical rock).

2024年4月23日 · Sediment can consist of rocks and minerals, as well as the remains of plants and animals. It can be as small as a grain of sand or as large as a boulder. Sediment moves from one place to another through the process of erosion. Erosion is the …

2024年4月11日 · Weathering involves exposure of pre-existing rock to Earth’s surface weather conditions. These “agents” include wind, water and ice — plus gravity. Erosion is the removal of weathered rock material from its original location. The effects of weathering on pre-existing rock can be both physical and chemical.

2023年7月10日 · The basic principle is that the coarser sizes settle faster than the finer sizes. Devices that are used to measure fine particle sizes in this way are called settling tubes. The governing principle is that each particle has a terminal fall speed that is a function of its size.
Sedimentary Rocks | Pictures, Characteristics, Textures, Types
Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks. Clastic sedimentary rocks form from the accumulation and lithification of mechanical weathering debris. Examples include: breccia, …
Sedimentology - Geosciences LibreTexts
Sedimentology addresses the study of modern sediments such as sand, silt, and clay, and the processes that result in their formation (erosion and weathering), transport, deposition and diagenesis.
Sedimentary Geology - Earth and Planetary Sciences
As rock weathers into sediments, they are transported across Earth's surface by gravity, water flows, and winds. Once deposited, sediments undergo physical and chemical transformations, mediated by groundwater, that turn them into sedimentary rocks.
Sedimentology | Stratigraphy, Depositional Environments
sedimentology, scientific discipline that is concerned with the physical and chemical properties of sedimentary rocks and the processes involved in their formation, including the transportation, deposition, and lithification (transformation to rock) of sediments.
