Coastal Systems and Landscapes

Flashcards covering concepts from Unit 1, Section 3.1 and 3.2 on open and closed systems, dynamic equilibrium, and coastal systems and landscapes.

What is an open system?

A system that interacts with other systems by having inputs and outputs.

Can you give an example of an open system?

A drainage basin; precipitation is an input and runoff is an output.

What is a closed system?

A system that is totally self-contained and does not input or output anything.

What is an example of a closed system?

The water cycle system, as water is not lost to or gained from space.

What is dynamic equilibrium?

A state of balance within a constantly changing system.

What is the erosion-flow line in coastal systems?

The line where the sea stops interacting with the land.

What defines the coastal boundary?

When the waves do not interact with the seabed, typically at depths of 5-10m.

How is 'the coast' defined?

A narrow zone where the land meets the sea.

Why is the coast considered to be constantly changing?

It is constantly changing due to the effect of land, marine, and air processes.

Why do we study coasts?

Because we have a connection with the coast (holidays), it is often in the news, and we pay tax for coastal protection.

What are some inputs into coastal systems?

Energy from waves, wind, tides, sea currents, sediment, geology of the coastline, sea level change, and coastal land.

What is a landform?

A part of the Earth's surface.

What is a landscape?

All visible features of an area.
