Q

A gorge is

A

A small trench where a river is situated at the bottom from waterfalls cutting back.

19
Q

A meander is

A

A bend or many in a river. It is created by erosion and overtime becomes and Ox bow lake

20
Q

An Ox bow lake is

A

The remains of a meander that is cut off from a water source. Eventually they dry up and become river scars.

21
Q

A floodplain is

A

Flat land at the same level as a river. Easy to flood.

22
Q

Levees are

A

Built up land either sides of rivers to prevent flooding

23
Q

An estuary is

A

Where the river meets the sea.

24
Q

A delta is

A

Where lots of sediment lower course builds up to create something as big as a tiny island.

25
Interlocking Spurs are
Small hills that intercept the river and force it to weave through.
26
A tributary is
A small or large river that joins into another river.
27
A confluence is
The precise point that a tributary joins a river.
28
A headland is
A type of promontory that is usually a sheer drop into water.
29
A bay is
An eroded part of coast, that creates headlands.
30
A spit is
A Coastal landform made by deposition from prevailing wind and river estuary.
31
A Natural Increase is when
The Birth rate is higher than the Death rate.
32
What is Birth rate?
It is the amount of people born per 1000 people.
33
What is Death rate?
It is the amount of people that die per 1000 people.
34
What is a Dependency ratio?
A dependency ratio is the ratio of people being able to work (16-64) and the people that can't (0-15 + 64-97)
35
What is a MNCs
A Multi National Company, e.g Apple, Rolls Royce.
36
What is Soft engineering?
Soft engineering is a low cost, local approach to Coastal landforms.
37
What is Hard engineering?
Hard engineering is an expensive, top down approach to coastal erosion.
38
What is a Rip-Rap?
A Rip-Rap is a coastal defence that is Hard engineering. It stops the erosion of the cliffs and hills behind it.
39
What is a Groyne?
A groyne is a coastal defence that stops the effects of Long-Shore-Drift
40
What is a Spit?
A Spit is formed from water pushing sediment into a river estuary, which creates a built up area of sand.
41
What is weather?
Weather is the current events of the atmosphere right now.
42
What is climate?
Climate is the weather of an area over 30 years.
43
What is a microclimate?
