What else can I help you with?
Which characteristic determines whether a rock is classified as a shale a siltstone a sandstone or a conglomerate?
the particle size of the sediments within the rock
What is the differences about grains and sediments?
Grains and sediments refer to different aspects of geological materials. Grains are the individual particles or fragments that make up rocks and sediments, often classified by size, shape, and composition. Sediments, on the other hand, are the accumulated deposits of these grains, typically formed through processes like weathering, erosion, and transportation. While grains emphasize the physical characteristics of the particles, sediments focus on the collective mass and the geological processes involved in their deposition.
What are the four classes of marine sediment?
Marine sediments are typically classified into four main classes: terrigenous, biogenous, hydrogenous, and cosmogenous. Terrigenous sediments originate from land, consisting of eroded rocks and soil transported by rivers and wind. Biogenous sediments are derived from biological materials, primarily the remains of marine organisms like foraminifera and diatoms. Hydrogenous sediments form directly from the precipitation of minerals from seawater, while cosmogenous sediments come from extraterrestrial sources, such as meteorites.
What is the group of rocks that are formed from sediments?
Sedimentary rocks are a group of rocks that form from the accumulation and lithification of sediments, such as sand, silt, and clay, that are deposited and compacted over time. These rocks often contain fossils and are classified based on their composition and texture.
What do we call the materials deposited by water wind and melting glaciers?
The materials deposited by water, wind, and melting glaciers are collectively referred to as "sediments." These sediments can take various forms, such as sand, silt, clay, and gravel, and are often classified based on their size and origin. When these sediments accumulate over time, they can form sedimentary rocks or contribute to soil development.

What two ways are rocks classified into?
Rocks are classified into two main groups based on how they are formed: igneous rocks, which are formed from cooling and solidifying magma or lava, and sedimentary rocks, which are formed from the accumulation and compression of sediments.
What is the group of rocks that are formed from sediments?
Sedimentary rocks are a group of rocks that form from the accumulation and lithification of sediments, such as sand, silt, and clay, that are deposited and compacted over time. These rocks often contain fossils and are classified based on their composition and texture.
What are the names of 4 sediments?
Globigerina ooze, limestone, silt, sand, and so on.
Why aren't rocks classified by their size?
Any rock could be virtually any size, so it would be of little use to use size as a classification parameter. Sediments or clasts composing sedimentary rocks, however, are classified according to size.
What are Detritus sedimentary rocks subdivided according to?
Detrital sedimentary are classified according to the size and shape of their sediments.
Rock families formed from the compression of sediments are called?
Sedimentary rock families formed from the compression of sediments are called lithified sedimentary rocks. These rocks are classified based on their composition, texture, and the process through which they were formed. Examples include sandstone, shale, and limestone.
