To cause the reaction, catalysts use the catalytic cycles, decomposition reactions, and combustion cycles.
<h3>What do you mean by a reaction?</h3>
A reaction refers to the chemical process where substances mutually act and are changed into different substances.
Catalytic cycles refer to the multistep reaction that involves the catalysts. It is considered the main method that describes the major role of catalysts.
Decomposition and combustion cycles are also used by the catalysts.
Therefore, A and B are the correct options.

Answer:
The sedimentary rock is a rock that has been made from other rocks that had existed in the Earth. The sedimentary rock has different layers of rock that can take form as gravel, stone, and maybe even a few gems inside. 
Explanation:
The first step would be that the rock would be in liquid form, 2nd stage would be the sludge stage, which would contain both solids and liquids, then overtime, the sedimentary rock would form. The Sedimentary rock can also be made out of mud and sand that has been under countless pressure overtime. But you would be most able to find one near deserts, lakes, seas, and rivers. So bodies of water would give you the advantage to find this rock.
 
        
                    
             
        
        
        
The answer is 
Longitudinal waves. 
The particle displacement in a longitudinal wave is
parallel to the direction of wave propagation. The ground particles simply oscillate
back and forth their equilibrium positions unlike transverse waves that do not
move along with the waves but rather oscillate up and down their individual
equilibrium positions.
