Q

the river tees background and info

A

-located in the north of england
-flows 137km from the pennines to the north sea at red car
-tees are narrow and carry sediments
-bed load= big, angular rocks which become smoother and smaller
-tees have a high level of erosive energy (HA+A)

22
Q

geomorphic process of river tees (upper course)

A

-V-shaped valley, rapids and waterfalls
-highforce waterfalls drop 21m and is made from Whinstone (igneous) and softer limestones rocks
-Gradually a gorge is formed

23
Q

geomorphic process of river tees (middle course)

A

-meanders and ox-bow lakes
-meander near Yarm encloses town

24
Q

geomorphic process of river tees (lower course)

A

-greater lateral erosion creates floodplains and levees
-mudflats at the rivers estuary

25
boscastle floods background
-small village, south west coast to the north of cornwall -population= 700 -90% of income is from tourism -river valency and jordan join -responding schemes cost £4.6 million
26
human causes of boscastle flood
-impermeable surfaces= prevent infiltration - shortens lag time -narrow bridges blocked off by debris - dam effect
27
physical causes of boscastle floods
-heavy rainfall (Aug 16th= 185mm) -soil saturated -steep sided valley
28
social effects of boscastle floods
-50 homes destroyed -150 vehicles swept away -jobs lost
29
economic effects of boscastle floods
-£85 million damage = sewage main burst -25 businesses closed -tourism increased
30
soft engineering techniques responding to the boscastle floods
-widen river channels -raising car parks -encourage land owners to carry out vegetation
31
hard engineering techniques responding to the boscastle floods
-artificially narrowing the river -lower river bed by 0.75m -new flood defence walls
32
Hunstanton background
- north west coast of norfolk -1953= storm surge - 307 deaths - 24000 homes destroyed
33
geomorphic processes of hunstanton
-beach widens between hunstanton and heacham -deposition at heacham= sand dunes -shingles includes white chalk from from hunstanton cliffs -LSD travels from hunstanton to heacham
34
soft engineering at hunstanton
-sand dunes -marram grass - adaptations= woody tissue (tough & strong), stems (grow quickly & elongate) -beach nourishment ($15 million)
35
hard engineering at hunstanton
-groynes= dont work (spaces in between gaps), sediments above groyne (works) -sea walls
36
landform at hunstanton
-wave cut platform= HA + A 1) sediments 2) red chalk 3) car stone= iron oxide rusts
37
amazon rainforest background
-in south america from the atlantic oceans to andes mountains and covers 60% of brazil -it has declined by 3.3 million sq km -hot (20-28*C all year) -convectional rainfall (2000m per year) -tall, evergreen trees=vegetation dense - very little light reaches floor
38
what is the nutrient cycle
1) trees shed leaves all year 2) decaying vegetation decomposes rapidly 3) nutrients enter soil 4) shallow roots take up nutrients 5) trees grow rapidly
39
what is the water cycle
1) heavy daily convectional rainfall 2) trees intercept rain 3) some rain reaches the ground 4) trees take up water 5) water evaporates
40
what are plants and animals adaptations in the amazon
-buttress roots= tall trees have this to support their trunks -drip-tips= plants have thick, waxy leaves with pointed tip which avoid damage to the plant and repel rain -parrots= strong sharp beaks to open nuts -poison dart frogs= bright colours to warn predators away
41
why deforestation happens in the amazon
-commercial farming (80%) e.g. cattle ranching -subsistence farming= farming on a small scale for foods for tribes (slash & burn) -logging e.g. mahogany for furniture -hydroelectric power e.g. Balbina dam - 920 sq miles removed
42
effects of deforestation (challenges)
-2030= 50% of all the species will be gone -loss of carbon sinks + emissions of CO2 -medicines extracted from plants e.g. rosy periwinkle (leukemia) - 2/3 cancer treatments -decline of indigenous tribes e.g. Amerindians = 6million now 1million
43
how is the amazon protected
-debt reduction= HICs write off debts but money must be used to invest in amazon -CITES (1978) (convention on international trade in endangered species) = inter-governmental agreements on trade & plants - protects 37000 species
44
leicester background
-city in the east midlands of england -population 330,000 -two major universities = 40000 students -premiership football and rugby teams
45
city opportunities in leicester
-social attractions e.g. shopping in city centre, diwali celebrations -knitwear & hosiery =service sector is the largest employer (retail) & financial sectors -20% greenhouse gas reduction target for 2020 -cyclepaths & bus routes
46
city challenges in leicester
-house prices increased with greater house shortages = development of brownfield and greenfield sites -high unemployment & inequality in housing in St Matthews -increased decline of greenfield sites in oadby/birstall
47
what is the highcross regeneration
-opened in 2008 -counteract decline in city centre shopping caused by fosse park -£350million = include shopping, restaurants, cinema, parking
48
positives of highcross
-3000 low skilled jobs created for St Matthews -others stores like Tk Max, primark or zara benefit -improved reputation
49
negative impacts of highcross
-Granby streets full of independent shops closed e.g. Fenwicks dpt store -increased traffic by car parks -highcross suffered a £63million loss in 2021
50
city opportunities in mexico city
-standard of living improves -very low unemployment rates - 50% in manufacturing industry -investment in sewage works to removed waste
51
city challenges in mexico city
-house shortages slums developed e.g. Neza-chalco-itza -50% work in informal sector -12000 tonnes of waste -water shortages -more than 4 million cars leads to poor air quality (like smoking 60cigs per day)
52
urban planning to improve QOL for urban poor in mexico city
-casa y cuidad = redevelop housing & provide residents with construction advice & train to help provide with long term jobs e.g. Azcapotzalco 75 homes rebuilt -Isla Urbana rainwater harvesting, health centres & schools - 250million litres of water
