Question

read the information in the box.
constructive and destructive forces can both help and harm surface features on earth. although we cannot prevent these natural forces from occurring, we can control their effects. for example, humans have built dams, levees, dikes, and storm drains to lessen the destruction to cities during a flood.
think about how humans can use technology and intervention to control constructive and destructive processes.
write about what happens to a beach through the process of erosion and weathering. how can humans help slow down these processes? how can humans protect the wildlife found in a beach ecosystem when destructive forces occur?

Explanation:

1. Erosion and Weathering on Beaches: Erosion (by waves, wind, water flow) and weathering (physical/chemical breakdown of rocks) remove sand, reshape shorelines, and reduce beach width. Sediments are transported, altering the beach’s profile.
2. Slowing Down Processes: Humans can build seawalls (to reduce wave impact), plant coastal vegetation (like mangroves or beach grasses to stabilize sand), use sand nourishment (adding sand to replenish eroded areas), and restrict coastal development to minimize disruption.
3. Protecting Wildlife: Create marine protected areas (MPAs) to safeguard habitats, relocate wildlife before destructive events (e.g., moving turtle nests), restore natural dunes (critical for species like shorebirds), and enforce regulations against pollution/habitat destruction.

Answer:

• Erosion/Weathering on Beaches: Waves, wind, and water erode sand; weathering breaks down rocks, reducing beach size and reshaping shorelines. Sediments are transported, altering the beach’s structure.
• Slowing Processes: Build seawalls, plant coastal vegetation (e.g., beach grasses), use sand nourishment, and limit coastal development.
• Protecting Wildlife: Establish MPAs, relocate vulnerable species (e.g., turtle nests), restore dunes, and regulate pollution/habitat destruction.
