Beach Regions Flashcard

Front

What is the foreshore region of a beach?

Back

The foreshore is the area of a beach that is affected by both high and low tides, typically where waves break and recede.

Front

What is a sand bar?

Back

A sand bar is a feature located between the trough and the seacliff, formed by the accumulation of sand due to wave action.

Front

What are dunes in the context of beach regions?

Back

Dunes are elevated areas of sand that are typically the most stable and least affected by daily tides, providing a buffer against wind and water.

Front

What is a beach terrace?

Back

A beach terrace is a flat area on the beach that is often exposed during low tide, providing a habitat for various marine organisms.

Front

What is a storm bar?

Back

A storm bar is a feature located between the offshore and the trough, formed during storm events when waves deposit sand.

Front

What is the offshore region of a beach?

Back

The offshore region is the area of the beach that is located beyond the breaking waves, typically where water is deeper and less affected by tides.

Front

What is the backshore region of a beach?

Back

The backshore is the area of the beach that is above the high tide line and is usually dry, often consisting of dunes or vegetation.

Front

How do tides affect the foreshore region?

Back

Tides cause the foreshore to be alternately submerged and exposed, influencing the types of organisms that can live there.

Front

What role do dunes play in beach ecosystems?

Back

Dunes provide habitat for various species, protect inland areas from storm surges, and help stabilize the beach with their vegetation.

Front

What is the significance of sand bars in coastal environments?

Back

Sand bars can influence wave patterns, create sheltered areas for marine life, and affect sediment transport along the coast.
