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:

Erosion refers to the transportation of materials (sediments) from one place to another with the help of agents like wind, water and ice.

The waves are often created because of the friction that takes place between the wind and the surface of the ocean water. This waves are of generally divided into 2 types, namely-

(1) Wind-driven waves

(2) Surface waves.

These waves have the potential to break down the rocks of coastal areas. In addition to this, these waves also carries the sand from the beach to offshore and from offshore to the beach areas. Thus, there is a consistent transportation of sand from the land to ocean.

Thus, the waves carrying the coastal sand into the sea from the beach is an example of erosion.

Hence, the correct answer is option (C).

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
