Where is limestone made?
Like most other sedimentary rocks, limestone is composed of grains; however, most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera.
Is limestone made of animal skin?
"Limestones are composed of grains; however, most grains in limestone are skeletal fragments of marine organisms such as Coral or Foraminifera."
Which rock is most likely to have grains cemented together?
Limestone
Is chalk sedimentary?
Yes,!! Chalk is fine grains of limestone compressed together and limestone is sedimentary, so chalk has to sedimentary.
What kind of rocks we can consider as sedimentary rocks-?
Slate (compressed silt and mud); Sandstone (compressed sand grains); and limestone (the skeleton remains of microscopic shelled creatures).
What is the difference between sandstone and limestone in terms of where they came from?
Sandstone is made chiefly of quartz or feldspar grains, and limestone of calcium carbonate grains. Sand grains are usually formed by the erosion of older rocks. Calcium carbonate grains may be formed by the evaporation of sea water, or by the deposition of the exoskeletons of sea creatures.
What is limestone like?
limestone is rough, it crumbles and absorbs water, this is because it is porous which means that it has tiny holes in it. limestone is made up of tiny grains they are circular and are really small
What is limestone's grain shape?
Limestone typically has a fine to medium-grained texture, with individual grains being mostly composed of calcium carbonate. The grains in limestone can have various shapes including rounded, angular, or elongated, depending on the specific conditions under which the rock was formed.
What is sandstone and limestone each made of?
Sandstone is compressed sand grains, and limestone is the compressed minute skeletal remains of ancient sea creatures.
What is the chemistry of limestone?
The limestone consists mainly of calcium carbonate: CaCO3 ,Calcite. Like most other sedimentary rocks, limestones are composed of grains, however, around 80-90% of limestone grains are skeletal fragments of marine organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts, and extraclasts. Some limestones do not consist of grains at all and are formed completely by the chemical precipitation of calcite or aragonite. (i.e. travertine.)
What kind of is limestone?
Sedimentary
Why sandstone is more porous than limestone and shale?
because it's grains aren't interlocking
