What effects can erosion have on a beach? select the two correct answers.
it can cause wider beaches.
it can cause lower beach elevations.
it can cause narrower beaches.
it can cause an increase in sand on beaches.
it can cause higher beach elevations.

Erosion refers to the leaching and breaking of soil that is not available for cultivating and harvesting crops. The coastal erosion has contributed to the structural damages and erosion of sand.

The correct answers are:

Option C. It can cause narrower beaches.

Option D. It can cause an increase in the sand on beaches.

The effects of erosion beach include:

1. The coastal erosion leads to strong wave action, a rise in the sea level, and coastal flooding. The particles, sand, and rocks are worn off and carried away by the shore, leading to the narrowing of the beach.

2. Higher the degrees of erosion and causes of coastal erosions, more the wearing of rocks and sand on the beach. The coastal erosion leads to an increase in the sand.

Thus, the correct options are Option C and D.

It can cause narrower beaches.

It can cause an increase in sand on beaches.

Explanation:

Beaches are temporary features. There is always sand being removed and sand being added to them. Often, they change drastically during the year, depending upon the frequency of storms.

Ultimately, a beach erodes because the supply of sand to the beach can not keep up with the loss of sand to the sea. Most sand is transported from inland via rivers and streams. The damming of most waterways in the US has thus prevented a major supply of sand from getting to our beaches. Sand can also be transported from beach to beach along a shoreline but this is mostly just a redistribution of sand that is already on the coast. The problem of beach loss can be exaggerated if sea level rises relative to the land (either due to true sea level change or geological sinking of the coast line). On an uninhabited shoreline, new beach can be created further inland. But, when the encroaching sea comes against people's property, the tendency is for people to try and stop the encroaching sea. They armor the shoreline with seawalls, revetments, jetties, etc. These have a negative effect on beaches because once sea water reaches them, it "bounces" off them with more energy than a wave washing back off a normal sand beach. More sand is carried off shore, promoting beach loss. Additionally, jetties placed perpendicular to the beach, disrupting along-beach currents and causing sand loss downstream of the jetty.
