What class of sedimentary rocks is made of fragments of rock minerals and shells?
The class of sedimentary rocks made of fragments of rock minerals and shells is known as clastic sedimentary rocks. These rocks form from the accumulation and lithification of sediments such as sand, silt, clay, and sometimes organic material. Examples include sandstone, shale, and conglomerate.
What is the type of Rock formed when smaller bits of rock become pressed or cemented together?
The type of rock formed when smaller bits of rock become pressed or cemented together is called sedimentary rock. This process involves the accumulation and compaction of sediments over time, which solidify to form sedimentary rocks.
When a rock is weathered or eroded it becomes what kind of rocks?
When a rock is weathered or eroded, it can become sedimentary rock. This process involves the breakdown and transportation of rock particles, which then accumulate and eventually form sedimentary rocks through processes like compaction and cementation.
What are the 3 main groups of sedimentary rock?
#1. Clastic or Detrital Sedimentary Rocks The class(t)ic route begins with the weathering and erosion of sedimentary, igneous, or metamorphic rocks. Through these processes, larger rock is broken up into smaller particles which are transported by moving water, ice, gravity or wind, and deposited at the bottom of a lake, a river delta, an ocean, or similar location where further movement is restricted or slowed down. The rock particles can range in size from boulders to clay particles less than .002 mm in diameter. If these rock particles are covered by additional particles, eventually the weight from above will start the process of lithification. Lithification is the compaction and cementation of particles which form rock. Compaction squeezes out the fluids and space that exist between the particles, and cementation results when the fluids that are squeezed out are replaced with minerals that were in the fluids. Once cementation occurs, the new sedimentary rock has been formed. Rocks formed in this manner include sandstone, shale, mudstone, breccia, and conglomerate and are called clastic sedimentary rocks. #2. Organic Sedimentary Rocks Some limestones and coal are formed largely from the remains of once living organisms. Chalk and fossiliferous limestones are formed from the skeletons of marine organisms. Coal is formed from vegetation that previously existed in swampy and marshy waterlogged soils which prevented their full decay after their death. As their remains piled up and were covered by more and more deposits, they gradually underwent compaction and cementation as described in #1. above. #3. Chemical Sedimentary RocksSedimentary rocks can also form when minerals in a body of water have so saturated the water that they precipitate out, like a cloud that is so full of moisture that it pours out rain. Some limestones are formed in this manner as the mineral calcite precipitates out of a saturated solution and undergoes the process of compaction and cementation. The supersaturated solutions can also be caused by evaporation of a body of water high in mineral content. As the water evaporates, the mineral percentage of the remaining solution becomes higher and higher, until the mineral crystallizes. Rocks such as rock salt and rock gypsum are formed in this manner. Sedimentation from precipitation and evaporation form rocks called chemical sedimentary rocks.
What is the process of which new rock forms from old rocks?
There are several ways by which old rocks can become "new" rocks, all of which are described by the rock cycle. A rock, no matter what class it falls under, can become igneous, metamorphic, or sedimentary. When melted and then re-cooled, a rock become igneous. When exposed to very high temperature and pressure, the rock becomes metamorphic. When weather or eroded by wind, water, etc., and then lithified (cemented together), the rock becomes sedimentary. Again, any rock can go from one class to the other, or in some cases become a new rock of the same class.

Sandstone is in what class?
Sandstone is a sedimentary rock classified as a clastic sedimentary rock. It is primarily composed of sand-sized mineral particles or rock fragments, typically quartz or feldspar, that have been compacted and cemented together over time.
To what class of sedimentary rocks does Breccia belong to?
Breccia is a clastic sedimentary rock.
What is a class that include sedimentary rocks which are deposited from a solution made by organic process?
Biochemical sedimentary rocks.

What is the class that contains clams is named for the two shells each member has?
Bivalves. :)
What phylum and class does actinophrys?
Actinophyrx has an amoeboid body and glassy silica shells. They belong to the phylum Sarcodina and class Heliozoa.
Is sedimentary rock sandy?
Not necessarily. There is a special class of sedmentary rocks, called sandstones, which are dominated by sand-sized grains. Other sedimentary rocks, such as shale, contain much finer grains.
