# Weathering--the physical or chemical breakdown of rock into smaller particles. # Erosion--occurs when water, wind, ice, or gravity transport the rock particles. # Deposition-- the process by which sediment settles out of the water, wind, or ice carrying it. # Compaction- the process that presses sediments together, squeezing out air and fluids from spaces between particles. # Cementation- the process in which dissolved minerals crystalize and glue particles of sediment together. Note: it takes millions of years for compaction and cementation to transform loose sediments into solid sedimentary rock

Which characteristics are used to identify sedimentary rocks?
Sedimentary rocks were created through multiple instances of applied pressure and natural cementation. They're rarely shiny since they did not make contact with concentrated sources of heat. Sedimentary rocks are generally coarse-grained and not shiny.
How are detrital chemical and biochemical sedimentary rocks different?
Detrital rocks are composed of rock particles, chemical sedimentary rocks are composed of precipitated minerals.Examples:Detrital or clastic rocks:ConglomerateBrecciaSandstoneShaleChemical sedimentary rocks:Rock saltSome limestonesRock gypsumWhat_is_the_difference_between_detrital_and_chemical_sedimentary_rock
What important properties does Breccia have that make it a useful rock?
Breccia is a useful rock due to its strength and durability, making it ideal for construction and building materials. It also has a unique appearance with its angular fragments, which can enhance the aesthetic value of architectural designs. Additionally, its composition can provide insights into the geological processes that formed it.
What is the rock conglomerate used for?
Conglomerate is a sedimentary rock. It is rounded, shiny and looks like it is made up of pebbles. It can be used for construction, the inside of walls and even polished to make decorations. This is because it is not very strong and is basically used for decoration.
What are examples of organic sedimentary rock?
Examples of organic sedimentary rocks include coal, which forms from the accumulation and compaction of plant remains, and limestone, which can contain organic debris such as shells and coral. Organic sedimentary rocks are derived from the remains of living organisms.
What is the size of a clastic sedimentary rock?
Sedimentary rocks are solid and can break into bit (rocks) of various sizes. However, if you mean what are the sizes of a "clast" in a clastic sedimentary rock then the answer is the same. A "clast" is a fragment of rock that is included in a new forming sedimentary rock - the term "clast" does not imply a size and indeed in a clastic sedimentary rock the clasts are frequently of many sizes.
What is a rock that forms from many small fragments of other rocks?
Clastic sedimentary rocks.
What the difference between clastic and chemical sedimentary rock?
The chemical sedimentary rock will not be composed of cemented rock particles.
What are three types of sedimentary rocks?
Clastic, chemical, and Organic
What is the most common non-clastic sedimentary rock?
The most common non-clastic sedimentary rock is limestone, which is primarily composed of calcium carbonate. It forms from the accumulation of organic remains such as shells and coral, or through chemical processes like precipitation from seawater. Limestone is widespread and found in many different environments around the world.
Which property is more important for each sedimentary rock type?
Grain size is more important for determining the classification of clastic sedimentary rocks, such as sandstone or shale. Composition is more important for determining the classification of chemical sedimentary rocks, such as limestone or rock salt. Layering is more important for identifying the structure of sedimentary rocks, such as bedding in sandstone or shale.
How many different types of sedimentary rocks are there?
There are many different types of sedimentary rocks. The three main types are chemical, biochemical and clastic rock. Some that fall into these three categories include sandstone, shale, limestone, gypsum, chert, coal, and amber.
Is shale an evaporite?
Yes it is, another evapourite rock would be dolomite. There are also many evapourite minerals.
Is sandstone hard rock?
Yes, it is.
How are sedimentary rocks mader?
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.
Do sedimentary rocks form from the remains of living things?
Some sedimentary rocks are formed at least partially of the remains of living things, but many are not. Fossil-rich rocks, coal, and some types of limestone are composed partly of the remains of organisms. Clastic sedimentary rocks such as shale and sandstone are made from sediment that has weathered out of pre-existing rock.
How many rocks did you classify as sedmentary?
sedimentary rocks are those which have been eroded from the earth and have had layers of mud and other rock put ontop of them, these then could create fossils. Some sedimentary rocks are such as limestone, mudstone, slate and marble.
