Fine-grained sedimentary rocks are classified by grain size and range from those composed of sub-microscopic particles (chert) to those with sand-sized particles (sandstone).
No, pebbles are not necessarily igneous rocks by default. Pebbles can be formed from a variety of rock types, including igneous, sedimentary, and metamorphic rocks, depending on the geological processes that created them.
In clastic sedimentary rocks, you can find clasts such as sand, silt, and clay. Organic sedimentary rocks contain remnants of organic material like plant fragments or shells. In chemical sedimentary rocks, you'll find minerals that have precipitated out of solution, such as calcite or halite.
what group of rocks does sandstone belong to? give a three nameof a elements mentioed? what is the name of one compound mentioned?
clastic,organic,chemical those are the only ones i know.
A very old fossil in sedimentary rocks is called a "trace fossil" or "index fossil." These fossils provide valuable information about past life forms and help scientists understand Earth's history.
Sedimentary, igneous and metamorphic.
Igneous, sedimentary, and metamorphic rocks are the three main types of rocks. Igneous rocks are formed from the cooling of molten rock, sedimentary rocks from the accumulation of sediment, and metamorphic rocks from the transformation of existing rocks under heat and pressure.

Igneous, Sedimentary, and Metamorphic
There are different ways sedimentary rocks are formed. Many sedimentary rocks are made from the broken pieces and particles of other rocks, [which is a reason why the name was given to these types of rocks (sediment)] and these bits get cemented together. These types of sedimentary rocks are called clastic sedimentary rocks. Chemical sedimentary rocks are another type that comprise of mineral crystals, like gypsum and halite. Lastly, organic sedimentary rocks are made of, well...... organic materials. They are made of the remains of once living organisms and contain the remains of living creatures such as clam shells, plankton skeletons, dinosaur bones, and plants.

The three types of rocks involved in the rock cycle are igneous rocks, sedimentary rocks, and metamorphic rocks. Igneous rocks form from the solidification of molten magma, sedimentary rocks form from the deposition and lithification of sediments, and metamorphic rocks form from pre-existing rocks that are subjected to high heat and pressure.
No, pebbles are not necessarily igneous rocks by default. Pebbles can be formed from a variety of rock types, including igneous, sedimentary, and metamorphic rocks, depending on the geological processes that created them.
The three main types of rocks are igneous, formed from cooling lava or magma; sedimentary, formed from compressed layers of sediment; and metamorphic, formed from existing rocks that undergo high heat and pressure.
