Answer :
Final answer:
The decrease in beach sand during winters is due to the stronger and more erosive winter storms and human activities such as dredging. This process can cause beach and marine ecosystem damage while also affecting local businesses like tourism and fishing.
Explanation:
The decline in beach sand during winter is due to a combination of factors, primarily including harsh winter storms and human activities such as dredging.
Winter storms tend to be more powerful and erosive than summer ones, causing a considerable amount of sand displacement. As waves reach shore, their energy is compressed due to decreasing water depth, creating higher waves – an effect called shoaling. This can lead to coastal erosion, and consequently, reduced amounts of sand on the beach during winter.
In addition, dredging projects, often carried out in an attempt to protect beachfront property from coastal erosion, have resulted in signs of greater storm impact on shorelines. Dredging can damage reefs, seagrass beds, and shorelines which can potentially trigger sand losses and cause substantial harm to marine life.
It's also worth noting that humans and wildlife, such as loggerhead sea turtle hatchlings, can displace sand, further contributing to the reduction of beach sand during winter.
