How does erosion affect coastlines?

Erosion affects coastlines through several natural forces[1]. Frost, heat, rain, floods, rivers, tides, currents and the action of tempest-tossed waters all contribute to the slow but sure change in the configuration of our coast line[1]. Land is worn gradually away in one place, while it is added to in another[1].

The hardest rock on our iron-bound coasts, as well as the friable soil of our soft and sandy shores, yields sooner or later to the erosive action[1]. As a result, the adjacent sea receives a vast quantity of rocky and earthy matter[1].
