The larger and more jagged the rock particles in a sedimentary rock, the closer their point of origin is. For instance, shale may consist of particles of rock that have been transported for hundreds of miles by water, being sorted to a very fine particle. Breccias, however, may indicate a very rapid transportation and deposition by turbid waters.

Bedding planes in sedimentary rocks indicate what?

Bedding planes in sedimentary rocks indicate the separate layers or strata in which the sediment has been deposited over time. These planes can provide important information about the environment in which the rock was formed, including factors like sedimentation rate, depositional environment, and past geological events.


Ripple marks likely indicate that a rock formed?

Ripple marks likely indicate that a rock formed in a sedimentary environment, such as near a shoreline or in a river bed, where the movement of water created the distinct ripple pattern in the sediment before it hardened into rock. These marks provide information about the ancient depositional environment and the direction of water flow at the time of formation.


What are the 3 types of sedimentary?

Mechanically formed sedimentary rock , Chemically formed sedimentary rock and Organically formed sedimentary rock.


What two things do sedimentary rocks record?

Sedimentary rocks can record information about the environment in which they formed, such as the presence of water, wind, or ice. They can also preserve evidence of the organisms that lived in that environment, including fossils.


Which sedimentary rock type is likely to be formed in the most offshore environment?

Shale is the sedimentary rock type that is likely to be formed in the most offshore environment. Shale is made up of fine clay particles that settle in quiet water far from the influence of waves and currents.


What does a red bed indicate about the atmosphere when it formed?

A red bed indicates that the sedimentary rock was likely formed under oxidizing conditions, where iron minerals were exposed to oxygen, causing them to rust and turn red. This suggests that the environment was well-aerated and had abundant oxygen at the time of deposition.


What feature of sedimentary rock is common to nearly every type of sedimentary rock?

The feature common to nearly every type of sedimentary rock is layering, known as stratification, which is formed by the accumulation and compaction of sediments over time. This layering provides information about the environment in which the rock was formed.


What do ripple marks likely indicate that a rock formed?

Ripple marks typically indicate that a rock formed in a shallow, watery environment, such as a riverbed, lake, or coastal area. These features are created by the movement of water over sediment, leading to the formation of small, wavelike patterns. Consequently, the presence of ripple marks in sedimentary rocks suggests that they were deposited in conditions where currents or waves were active.


Rock type that is formed when sediment is lithified?

Sedimentary rock can be formed from lithified sediments.


Sedimentary rock formed from sand?

Sedimentary rock formed from sand is called sandstone.


What sedimentary rocks are formed from the remains of plants and animals?

Sedimentary rocks formed from the remains of plants and animals are called organic sedimentary rocks. Examples include coal, formed from the remains of plants, and limestone, formed from the shells of marine organisms.


What rocks is formed in layers?

Sedimentary rock, like limestone, is formed in layers.
