What types of rocks may be deposited sediments?
Sedimentary rocks are primarily formed from deposited sediments, which can include fragments of igneous, metamorphic, and older sedimentary rocks. These sediments are transported by water, wind, or ice and accumulate in layers over time. Common types of sedimentary rocks include sandstone, limestone, and shale, which are formed from sand, biological materials, and clay, respectively. Additionally, volcanic ash can also contribute to sedimentary deposits.
What is called when organisms are trapped in sedimentary rock?
when an organism is trapped in sedimentary rock, it will die and the organism will slowly decay, but it won't decay altogether and you get a fossil. the older the fossil is the lower down it will be in a sedimentary layer. that's called superposition...
How do clastic rocks differ from non clastic rocks in terms of process of formation?
Clastic rocks are composed of broken pieces of older rocks that have been broken up by the process of weathering and are therefore sedimentary in nature. The "clasts" (bits of older rock) may vary in size.
What is the method of determining whether a fossil is older or younger than other fossils found in the many layers of sedimentary rock is called what?
relative dating
Is it true to say that radioactive istopes in clastic sedimentary rocks always predict an age that is younger than the sedimentary rock?
No, radioactive isotopes in clastic sedimentary rocks can provide ages that are younger, older, or similar to the actual age of the rock. The key is to select an appropriate radioactive isotope with a suitable half-life that aligns with the age range of the sedimentary rock being studied.
What are sedimentary rock composed of older rocks called?
Sedimentary rocks composed of older rocks are called "conglomerate" or "breccia." These rocks form when fragments of older rocks are compacted and cemented together to create a new rock.
Which type of rock is formed from the cementing of small pieces of older rocks shells soil or dead plants and animals?
Sedimentary rock is formed from the cementing of small pieces of older rocks, shells, soil, or dead plants and animals. These fragments, called sediments, can be compacted and cemented together over time to create sedimentary rock. Examples of sedimentary rocks include sandstone, limestone, and shale.
What are some sedimentary rocks that are classic rocks as well?
Classic sedimentary rocks are made up a minerals, grains, and rock fragments from older rocks. Some examples of this kind of rock are sandstone, breccia, and shale.
Radiometric dating does not usually work with sedimentary rocks because they?
Radiometric dating is not usually effective for sedimentary rocks because they are formed from fragments of other rocks and do not contain the necessary minerals for radioactive decay dating to occur. Sedimentary rocks are composed of material that has been transported and deposited, which can result in a mixture of ages making it difficult to determine the exact age using radiometric dating methods.
Scientists date igneous rocks to indirectly date nearby sedimentary rocks Why doesn't radiometric dating typically work on sedimentary rocks?
Radiometric dating relies on the presence of radioactive isotopes that decay over time into stable isotopes. Sedimentary rocks are composed of weathered fragments of other rocks and minerals, so they do not usually contain the necessary radioactive isotopes for radiometric dating. This makes it difficult to directly date sedimentary rocks using radiometric methods.
What is sedimentary rock in which the older rocksunless disruptedare on the bottom?
The type of sedimentary rock in which the older rocks, unless disrupted, are on the bottom is called a fossil-rich limestone. This rock contains fossil remains of prehistoric organisms.
How are clastic rocks and organic rocks similar?
Clastic: These rocks are composed predominantly of broken pieces of older weathered and eroded rocksNon-clastic/ Organic: A sedimentary rock composed of the remains of plants and animals.just figure it out!

What is a sedimentary rock in which the older rocks unless disrupted are on the bottom?
This type of sedimentary rock is called a "nonconformity." It occurs when younger sedimentary layers are deposited on top of older, often deformed or eroded, igneous or metamorphic rocks. Nonconformities indicate a significant gap in the geological record due to erosion or tectonic activity.
What rock is made of older rocks from a period of time?
sedimentary
What is the difference between clastic and chemical rocks?
Clastic: These rocks are composed predominantly of broken pieces of older weathered and eroded rocks Non-clastic/ Organic: A sedimentary rock composed of the remains of plants and animals.
