Which of the following is the best example of erosion? a Sediment piling up at the mouth of a river

b Plant roots growing through concrete and splitting it

c Waves carrying sand away from a beach

d A large rock splitting into pieces because of ice

Option C

Explanation:

Remember erosion is the process of moving sediments to one location to another. In this case waves moving sand away from the beach and to another location is erosion which means your answer is option C. It's not option B because plant roots breaking apart concert is a example of weathering, and the same goes for option D.

Hope this helps.

h let me think

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
