47. What causes the change in shape of beaches and barrier islands along Florida's coast when a hurricane or other strong storm strikes? A. The rain from the storm erodes the sand. B. The storm's waves erode the rock beneath the sand. C. Tornadoes created by the storms lift the sand and deposit it into the ocean. D. The storms generate wind and waves that shift the sand from one location to another.

D. The storms generate wind and waves that shift the sand from one location to another.

Extra: When a hurricane or other strong storm hits the coast, the powerful winds and waves can have a dramatic effect on the landscape of beaches and barrier islands. The strong energy from the waves, wind, and storm surges can erode the shoreline as the water pulls sand and other sediments back into the ocean. Additionally, waves can deposit sand at different locations, changing the shape and size of the beaches and barrier islands.

Barrier islands are particularly susceptible to change during storms. They are dynamic systems made of sand and are influenced by the daily and seasonal actions of waves, tides, and currents. Over time, these natural forces can cause barrier islands to slowly migrate landward or along the coast.

Hurricanes and strong storms can accelerate this process, causing rapid coastal change in a short period of time. The severe winds can also contribute to coastal dune erosion as they transport sand inland. The combination of strong wave action, storm surges, and high winds can lead to significant alterations in coastal geomorphology, sometimes reshaping the landscape in just hours or days.

This process is natural and has been occurring for thousands of years; however, the presence of human infrastructure and activity can exacerbate the vulnerability of these environments, leading to more severe damage and loss of property and ecosystems during major storm events.
