Waves washing over rocks on the beach is the correct example of natural erosion because waves from any water body are naturally generated by the effect of wind and gravity these can wipe the surface materials present over the rocks on the beach.

Erosion occurs when overland flow moves soil particles downslope. The rock materials carried by erosion is the load of the river. This load acts as a grinding tool helping in cutting the bottom and sides of the river bed, resulting in deepening and widening of the river channel.

Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows.

Why is artificial erosion a concern if erosion can occur naturally? a. Artificial erosion changes environments while natural erosion does not. Artificial erosion occurs at a faster rate than natural erosion.

The changes to ecosystems that occur through natural erosion are gradual as well, so ecosystems are able to adapt. Artificial erosion, however, occurs 10 to 15 times more rapidly than natural erosion. This makes it difficult for ecosystems to adjust to the changes.

A slope failure is a phenomenon that a slope collapses abruptly due to weakened self-retainability of the earth under the influence of a rainfall or an earthquake. Because of sudden collapse of slope, many people fail to escape from it if it occurs near a residential area, thus resulting in a higher rate of fatalities.

Slopes steeper than 2:1 will usually require special stabilization measures such as a crushed rock or riprap layer, crib wall or revetment. Additionally, sod can be used to stabilize steep slopes instead of seeding where grades are not more than 2:1. Sod on slopes steeper than 3:1 should be pegged.

There are many methods that can be used to stabilize a rock slope. These include altering the slope geometry, installing drainage, adding reinforcement, or a using combinations of these methods.

adjective. A gentle slope or curve is not steep or severe.

SOIL AMENDMENTS, SUCH AS TOPSOIL, CLAY, MUCK, AND PEAT INCORPORATED INTO THE SAND, PLUS SEEDING; OR MULCHING COMBINED WITH SEEDING; OR SPRIGGING HAVE BEEN USED SUCCESSFULLY BY SEVERAL STATES TO STABILIZE SAND EMBANKMENTS.
