extreme weather conditions

Question 5

effects of deforestation

Answer 5

habitats are lost
deforestation leads to soil erosion and flooding

Question 6

linear economy

Answer 6

works on the principles of take, make and dispose.
often from finite resources
not made to be recycled,reused
simply disposed at end of life

Question 7

the natural answer

Answer 7

works in a circular way
plant grows from seed
animals feed
seeds are spread as droppings
predation enables supply of energy for animal to animal

use(operation maintenance reuse)
recycling (end of life)

Question 21

advantages of global manufacture

Answer 21

greater flexibility
utilise greater manufacturing facilities abroad
economic savings due to lower abroad costs
access to larger workforces

Question 22

renewable energy

Answer 22

comes from sustainable sources which create little/no waste/pollutants
do not release co2

Question 23

solar energy

Answer 23

first photovoltaic cells(1839)
1958 photovoltaic panels
further products developed increased efficiency and lowered cost

Question 24

wind energy
