Geography Term 1

Flashcards for my weakest subject ;)

Longshore drift

The geological process where waves transport sediment (like sand, pebbles, and shingle) sideways along a coastline in a distinct zigzag pattern

Population distribution

The spatial pattern showing how human settlement is spread across a country or the globe.

Life expectancy

The average number of years a person is expected to live from birth ON AVERAGE.

Swash

The movement of water up a beach after a wave breaks.

Destructive wave

A high-energy wave with a strong backward movement that erodes beach sediment.

Spit

A long, narrow ridge of sand or shingle connected to land at one end and extending across a bay or river mouth.

Birth rate

The annual number of live births per 1,000 individuals in a given population.

Death rate

The annual number of deaths per 1,000 individuals in a given population.

Wave-cut platform

A flat, rocky bench left at the base of a retreating cliff line after wave action collapses overhangs.

Bay

A broad, curved inlet formed where waves erode softer rock between two harder rock outcrops.

Sea stack

A tall, isolated column of rock left standing in the water after an arch collapses.

Headland

A coastal landform made of hard rock that projects out into the sea, resisting wave erosion.

Constructive wave

A wave with a strong forward water motion and weak backward movement that deposits sediment on a beach.

Backwash

The movement of water back down a beach towards the sea due to gravity.
