Geography - 1 - Case Studies And Processes

Front 1

Erosion

Back 1

the wearing away of rock and soil from river banks and coasts

Front 2

Erosion: Hydraulic Action

Back 2

is where water forces air into cracks and crevices, gradually wearing them away with time

Front 3

Erosion: Abrasion

Back 3

is where rocks carried by the river gradually wear away the banks and the bed

Front 4

Erosion: Attrition

Back 4

is when rocks carried by the river crash into each other creating smaller and smoother particles

Front 5

Transportation: Solution

Back 5

is when particles of rock dissolve into the river, and then gets carried away in its dissolved form

Front 6

Transportation: Saltation

Back 6

is when small pebbles and stones bounce along the river bed.

Front 7

Transportation: Suspension

Back 7

is where small, light material is carried by the river

Front 8

Transportation: Traction

Back 8

is where large boulders and rocks roll along the river bed

Front 9

MEDC Flood
date:
Area:
Cause:
other:

Back 9

Boscastle Floods
16th Aughust 2004,
North West Cornwall,
The remnants of hurricane Alex / Masses of Rainfall / the confluence of the rivers Jordan &Valency,
No Deaths, £20 million price tag estimated by insurance companies

Front 10

How where the Boscastle floods dealt with:

Back 10

New flood defence wall
remove trees near the river so less debris
widen the river

Front 11

LEDC Floods
date:
Area:
Cause:
Other:

Back 11

Bangladesh floods
July - September 1998
India
Exceptionally heavy seasonal rains / River Ganges diverted for irrigation / Bangladeshi debt means that flood defences are unaffordable.
1040 people died, 2/3rds of the country was flooded, damage to farm land devastating

Front 12

How the Bangladesh Floods where dealt with:

Back 12

7,500km of flood embankment built
Water table to be lowered by crop irrigation
plans made for future warning and relief services

Front 13

what is the structure of rock at a waterfall?

Back 13

Hard rock slab at the top, with soft rock contained underneath

Front 14

Drainage Basin

Back 14

Colorado Drainage basin
hoover dam, aqueducts etc used to transport water over hundreds of kilometres to support the demand for water, a particular user of this water is las vegas

Front 15

What is population distribution?

Back 15

How spread out the population

Front 16

What is population distribution?

Back 16

How many people are in a given area

Front 17

how do you calculate population density?

Back 17

population
---------------- = population (km^2)
area (km)

Front 18

Give three examples of where you will find a sparse population density:

Back 18

High land (mountains)
unreliable water source
areas of forest

Front 19

Give three examples of where you will find a highly dense population density:

Back 19

areas of industrial development
Government investment in an area
Areas of grassland

Front 20

what is birth rate?

Back 20

the number of people born per 1,000 of the population

Front 21

why would a country have a high birth rate?
which type of country would usually have a high birthrate?

Back 21

social standards accept 5 or more children
one successful child may lift the family out of poverty
when women have little or no formal eduction

LEDC

Front 22

why would a country have a low birth rate?
which type of country would usually have a low birthrate?

Back 22

Well educated women
one or two children are socially acceptable
children are unlikely to contribute to family income

MEDC

Front 23

what is death rate?

Back 23

the number of people that die per 1,000 of the population

Front 24

why would a country have a high death rate?
which type of country would usually have a high death rate?

Back 24

Water shortage
dirty water
wars

Countries with a high birth rate will tend to have a high death rate

Front 25

why would a country have a low death rate?
which type of country would usually have a low death rate?

Back 25

good health care
not many natural disasters
clean water supply

Countries with a low birth rate will tend to have a low death rate

Front 26

What is the demographic transition model?

Back 26

its a graph that shows the typical evolution of birth and death rates as well as total population. most countries are stage 3 or 4 and only a few are in the beginnings of stage 5

Front 27

What is a population structure?

Back 27

It is a dual bar graph that shows that shows the distribution of males and females as well as age groups in the population
