In the rock cycle, sedimentary rock is heated and a squeezed to from metamorphic rock.
They are the types of rocks which are formed as a result of accumulation of minerals or organic particles at the surface of the earth.Sedimentation is the name given to a collective process which cause the particles to settle.
The study of sedimentary rocks is useful in civil engineering and as important sources of coal, fossil fuels and ores.The color of sedimentary rock is often determined by iron content and sometimes due to the presence of organic matter.
They are classified based on origin in to 4 types which are clastic, biochemical ,chemical and other sedimentary rocks.While based on composition they are classified as siliciclastic,carbonate ,evaporite,organic rich,siliceous ,iron-rich and phosphatic sedimentary rocks.

Answer:
air conditioning
Explanation:
Nitrogen can also bond with otherthree atoms because of its outer shell (valence shell) that has three electrons.This is the reason why organic molecules can be so large because of thisbonding. Suppose you have a compound of NH3. You know that hydrogen can onlyshare 1 electron because 7 of its electrons are filled. Also, in nitrogen, it canonly share 3 electrons because 5 of it are already filled. That is why nitrogenneeds three hydrogen to form NH3.
