Which two main forms of coastal erosion are identified?
Which of the following best describes the constant story beneath the surface of the planet's coastlines?
The mission to understand coastal landforms includes exploring their creation, the processes shaping them, and the urgent issues they currently face.
Which of these is NOT an example of a captivating beach mentioned?
The immediate appearance of a beach is the only factor that attracts people to coastal areas.
Match the coastal term with its description:
The active zone between the lowest tide and the highest point hit by storm waves.
The specified line marking the boundary between the shore and the coast, or the landward limit of the biggest storm waves.
Extends inland as far as features are clearly ocean-related.
Coastal areas are static landscapes that remain unchanged over long periods.
What is the primary component of the sand found on Florida's beaches?
Which of the following processes involves waves picking up and hurling sand, pebbles, and other sediment against cliffs and rocks?
Chemical weathering primarily involves the physical breakdown of rocks by wave action.
Match the coastal feature with the type of coastline where it is typically found:
Blowholes
Sea Arches
Sea Stacks
Headlands
Erosional coastlines
Erosional coastlines
Erosional coastlines
Erosional coastlines
What is left behind when a sea arch finally gives way?
Depositional coastlines are characterized by areas where the land is primarily being carved away by erosion.
Match the estuary type with its formation:
Tectonic estuaries
Fjords
Bar-built estuaries
Coastal plain estuaries
Formed by geological activity like faulting where land has dropped down, creating a basin that floods with seawater.
Formed when barrier islands or spits build up to partially cut off a lagoon from the open ocean.
Drowned river valleys flooded by rising sea levels after the last ice age.
Deep, narrow inlets with steep sides carved out by glaciers and then flooded.
The way freshwater and saltwater mix in an estuary is always uniform from top to bottom.
How do dams upstream contribute to coastal erosion?
Match the coastal management strategy with its description:
Hold the line
Advance the line
No active intervention
Managed realignment
Deciding not to build any new defenses or maintain existing ones, letting nature take its course.
Building new defenses seaward of the existing line, often involving land reclamation.
Committing to maintaining or upgrading existing defenses to keep the shoreline where it is now.
Strategically allowing the shoreline to move inland to a new, predetermined position.
Managed realignment is generally considered an economically and politically easy strategy to implement due to high public acceptance.
Rivers are considered biodiversity hotspots, specifically for deep-sea marine life.
