They are not the only ones that contain fossils, but they account for the highest percentage of fossil bearing rocks. And that's because their mode of formation supports fossil habitation.

A send rock is the only rock that contains fish fossils because, it’s one of the only rocks that are in the ocean.

What are two types of sedimentary rocks?
Sedimentary and igneous are types of rock (the other type is metamorphic). Sedimentary rocks are quite soft, and include chalk and limestone. Igneous rocks include granite and basalt. They are formed when magma cools.
What are the three rock types of science?
IGNEOUS refers to rocks that originate in the interior of the Earth, and include the various volcanic types and the granite group of rocks. There is a 1:1 correspondence between the granite types of rock, and the volcanic ones - it depends upon whether they have been melted or not. Granites usually have well differentiated crystals, and are hard. SEDIMENTARY rocks are those that have result from the weathering of the above igneous rocks, and in general are deposited as fine-grained sediments at sea, and this will eventually form rocks. METAMORPHIC rocks are generally formed from sedimentary rocks that have been subjected to heat and pressure. Consequently, the mineral assembly will differ from that of the sedimentary, new minerals will be formed, and shear and folding are common. The degree of metamorphism varies depending on the burial pressure and temperatures. In the extreme of melting, then granites will result if the cooling is very slow, or volcanics will form if the rock is ejected in the molten state. Marble is a curious metamorphic rock in that it may be formed from the hard bodies of tiny marine animals, but with a low degree of metamorphism, often fossils may still be recognized. At extreme metamorphism, it will become a matrix mainly of CaCO3.
What are tiny rocks made of?
Well little stones like gravle are just made of broken up stones and those are composed of differant minerals so small rocks are composed of minerals just like large ones. tiny rocks are made of spit.
How is magma part of the rock cycle?
The Rock Cycle follows a series of steps that may simplistically be considered as :- Plutonic rocks either erupting or emerging; followed by a mountain buildingprocess; followed by a surface weathering process which produces sediments that eventually find their way to the abyssal deeps of the ocean floor.These sediments may be consumed by subduction zones at some plate boundaries, and the sediments become deeply buried and heated. The high temperatures and pressure cause Metamorphic processes to proceed, thus making new rock minerals from the sedimentary mix. These can be investigated to determine the conditions at which these new minerals were formed.Some of these metamorphic rocks are borne directly to the surface again as new mountain ranges, for these sedimentary rocks are lighter than plutonic ones are. Otherwise, the descending rocks will be eventually absorbed into the magma. To begin the cycle over again.Because of the sedimentary rocks being lighter than the magmatic ones, they 'float' on the magma, forming long lasting continental plates. Some of the older ones date to about 4 billion years old.
What is a layer of soil?
there are many types of layers of soil first the sedimentary the soft ones then primary the really hard ones

What areas lends itself to the formation of fossils?
The Ocean bed is perhaps the best for formation of fossils since it is the most undisturbed. Other areas would include the ones with sedimentary rocks less than 500 million years old.
What kind of rocks are fossils found?
small ones mainly
What type of rocks are found in Japan?
Igneous Rocks, Sedimentary Rocks, SandStones, Cherts, and limestone.
Are sedimentary rocks similar to metamorphic rocks?
Sedimentary rocks are ones formed by solidified mud and loose earth. Metamorphic rocks are ones formed by some sort of change, such as melting and re-cooling. So they are similar in some senses (they are both rocks, both of the earth) but in others they are very different (physical properties).
What is the name of six sedimentary rocks?
clastic,organic,chemical those are the only ones i know.
How do you figure out how old rocks are by using their positions compared to each other?
With sedimentary rocks, young ones are usually on top of older ones. Where igneous rocks intrude into others, the intrusions must be younger than the surrounding rocks.
What type of rock is?
There are three major types of rocks: igneous, metamorphic, and sedimentary. Rocks are classified based on the process by which they were formed. Sedimentary rocks form from sand, dust, and tiny rock particles that are fused by water and extreme pressure over time. Igneous rocks form from cooled magma or lava; depending on how fast they were cooled and solidified, igneous rocks may or may not go through crystallization. Metamorphic rocks are rocks that changed from either sedimentary rocks, igneous ones, or other metamorphic rocks. These generally form from wind, water, or chemical erosion.
What types of rocks are found in Seattle Washington?
There are many types of rocks that are found in Washington state. The most common ones found are sedimentary rocks and metamorphic rocks.
How do sedimentary rock form from rock particles?
The heaver rocks settle to the bottom and the lighter ones stay on the top and they form layers!
Why are some sedimentary rocks hard and others are soft and tend to fall apart easily?
The harder ones are fairly newer, and the softer ones have been through more weathering.
Are sedimentary rocks are the only ones that can be solidified?
Rocks are invariably considered as solid, though on a geological scale, they may be plastic. Granites, and volcanic output are rocks, as are metamorphosed rocks such as marble ans schist. Liquid lava is not yet a rock but will be when it chills.
