They type of sedimentary rock that forms when sediments stick together?
Detrital sedimentary rock. clastic sedimentary A+
Sediments in sedimentary rocks are often held together by what?
Cement is what binds the siliclastic framework grains together. Cement is a secondary mineral that forms after deposition and during burial of the sandstone. These cementing materials may be either silicate minerals or non-silicate minerals, such as calcite.Silica cement can consist of either quartz or opal minerals. Quartz is the most common silicate mineral that acts as cement. In sandstone where there is silica cement present the quartz grains are attached to cement, this creates a rim around the quartz grain called overgrowth. The overgrowth retains the same crystallographic continuity of quartz framework grain that is being cemented. Opal cement is found in sandstones that are rich in volcanogenic materials, and very rarely is in other sandstones.Calcite cement is the most common carbonate cement. Calcite cement is an assortment of smaller calcite crystals. The cement adheres itself to the framework grains, this adhesion is what causes the framework grains to be adhered together.Other minerals that act as cements include: hematite, limonite, feldpsars, anhydrite, gypsum, barite, clay minerals, and zeolite minerals.
When does sediment become solid rocks?
the order sedimnets become solid rocks when water and air squeezed out from between the sedimnet layer. The sedimnets may also become solid rock when dissolved minerals in the water cement the sedimnts together
When a rock is exposed to chemical weathering what does it do?
The rock is broken down so it visibly recedes. This may be because the cement holding it together is broken down, or else because the minerals of which the rock is mainly composed are dissolved. Alternatively, rocks are broken down through acid rainfall, which is neutralised by limestone and other basic rocks, but at the expense of the rock itself, which then changes in composition and is easily removed.
What two minerals act as cement in sedimentary rocks?
Quartz, calcite, clay, and iron could all be cementing minerals in sedimentary rock.
Dissolved minerals separate from water and become a natural what that binds the sedimentary rock together?
cement
Where did sedimentany rock come from?
Sediments (sand, clay, boulders etc) are derived from the erosion of preexisting rocks by snow, ice, water and wind. Eventually these sediments settle and are covered by more sediments. As the weight of overlying sediments builds up the pressure and minerals dissolved in and carried by groundwater cement the sediment particles together to form a new rock layer. This new rock is called a sedimentary rock.
Where does a River erode sediment?
sediments are transported by ocean rift, streams, river currents, wind (air). they are deposited according to size. The largest sediments are deposited first. The sediments settle into the sand and are carried by the stream. Near the mouth of the stream where the water moves slowly the small sediments settle out. The larger sediments get carried by the river into the sea then the samller sediments. The sea water dissolved minerals and soak the sediments and cement together. This eventually forms sediments.
What type of dissolved minerals glue particles into one mass?
The minerals that precipitate from fluids to cement particles together to form sedimentary rocks could be calcite, quartz, clay, or iron minerals.
Were do the cements that hold sediments together come from?
Sedimentary rocks come from the fragments of pre-existing rocks called sediments. There are three types of sedimentary rocks, each coming from different kinds of sediments. Clastic sedimentary rocks are created from the broken pieces of other rocks, while chemical sedimentary rocks form from mineral crystals like halite and gypsum

How are the fragments glued together in sedimentary rocks?
Minerals crystallize out from the water surrounding the grains and act as cement.
What type of natural human-made concrete most resemble?
Some minerals have become like cement, holding the rock together.
Why isn't cement a mineral?
No. A rock is an assemblage of at least two different minerals. One mineral can't be two or more minerals.
