gerography paper 3 topic 1

Question 1

name 3 biomes

Answer 1

• rainforest
• taiga
• desert

Question 2

describe the taiga

(climate+ reason for climate -> pressure or/and latitude)

Answer 2

• cold and dry climate + low precipitation
• due to high pressure as the air sinks then gets hotter which causes no condensation and dryness
• high latitude which means its far from the equator so theres little area for the sun rays to travel to, making it cold

Question 3

describe the rainforest

( climate+ reason for climate -> pressure or/and latitude)

Answer 3

• hot and wet climate
• due to low pressure as the air then gets hotter which causes no condensation and dryness
• and its high latitude which means its far from the equator so theres little area for the sun rays to travel to, making it cold

Question 4

how does latitude affect climate

Answer 4

distance from equator so the further you are the harder it will be for thr sun rays to travel and cover a larger are so the climate will be colder :b

Question 5

what are 3 factors that could affect plant growth

Answer 5

*plant growth - too much or too little

*type of ground - some soil doesnt hold enough nutrience or hold enough water for trees to go grow

*altitude - high altitude will make aareas such as mountains to bee cold which wont aalow plants to grow

Question 6

explain what biodiversity is

Answer 6

a variety of special such as plants and animals and organisms

Question 7

what is abiotic and biotic

give examples

Answer 7

• abiotic - parts of a biome that were never living ( nutience )
• biotic - parts of a biome that are living or have lived ( trees or rotting wood )

Question 8

describe the nutient cycle

Answer 8

movement of nutrients from the physical environment to living organisms and back to the environment

Question 9

explain the types of services within an ecosystem

( provisional, supporting, regulating, cultural)

Answer 9

• provision - product obtained from ecosystem(coconut)
• supporting - helps keep ecosystem healthy so it provide other services
• regulating - services keep whole planet healthy by managing things (like climate change by releasing oxygen)
• cultural - benefitys people get from visiting?living in an ecosystem(camping –> gud well being)

Question 10

explain what the boserupian theory suggests about the future

Answer 10

• as the population increases
• invest new ways to allow more food to be grown
• human have alreadt created gm crops and better fertilisers
• so making more food will lead top th epopulation continuing to grow

Question 11

explain what the maltheus theory suggests for the future

Answer 11

• as the population increases
• food population will run out along with other recourcees such as enerfy andf clean water
• this will eventually lead to starvation and possibly war due to selfish countries
• then the population will finally fall

Question 12

what is low pressure and how does it affect climate

give example

Answer 12

• low pressure causes air to rise and get colder which means condensation occurs so the climate becomes wet bedcause of the rain

rainforest

Question 13

what is high pressure and how does it affect climate

give example

Answer 13

• high pressure causes air to sink and get hotter which means no condensation occurs so the climate becomes dry

tundra
