Climate change

Question 1

What human factors of climate change

Answer 1

fossils fuels , agriculture and deforestation

Question 2

what are the physical factors of climate change

Answer 2

orbital changes , solar output and volcanic activity

Question 3

how does fossil fuels cause climate change

Answer 3

burning fossil fuels releases carbon dioxide contribute to enhancing greenhouse gas effect

Question 4

how does agriculture cause climate change

Answer 4

larger populations demand for meat and animal grazing releases methane into atmosphere

Question 5

how does deforestation contribute to climate change

Answer 5

logging increases co2 as less photosynthesis occur

Question 6

how does volcanic activity account to climate change

Answer 6

volcanic gasses and ashes cover sunlight so reducing global temperature acts as cooling effect

Question 7

how does solar output contribute to climate change

Answer 7

sunspots increase every 11 years fewer sunspots in coldest periods

Question 8

how does orbital changes contribute to climate change

Answer 8

changes in which the earth orbits the sun changes affecting where sun hits earth and how intense the sun is which controls seasons

Question 9

suggest the four evidences for climate change

Answer 9

• increase in temp by 1 degree every year
• glaciers melting due to increase temperatures
• rising sea levels by 19cm since 1900
• warm ocean temperatures

Question 10

suggest the four evidences for climate change

Answer 10

• increase in temp by 1 degree every year
• glaciers melting due to increase temperatures
• rising sea levels by 19cm since 1900
• warm ocean temperatures

Question 11

what does increased temperature suggest to a persons health

Answer 11

can cause diseases such as skin cancer

Question 12

how does climate change make difficulties for farmers

Answer 12

decreases crop yield and require more irrigation

Question 13

what do droughts causes by climate change pose

Answer 13

reduce food and water supplies , water scarcity in southeast UK

Question 14

what does increase flood risk cause

Answer 14

repair cost and insurance cost

Question 15

how does low rainfall by climate cause problems

Answer 15

food shortages

Question 16

what does sea level rising by climate changes mean

Answer 16

coastal erosion and flooding

Question 17

what are the two ways of managing climate change

Answer 17

mitigation and adaptation

Question 18

what are the 4 ways of mitigating climate change

Answer 18

afforestation , alternative energy produce , carbon capture and international agreements

Question 19

explain alternatives of fossil fuels and why fossil fuels are bad

Answer 19

fossil fuels emit greenhouse gas and contribute to global warming therefore using tidal/wind/solar energy , hydro-electrical , nuclear power and geothermal we can prevent this

Question 20

explain carbon capture

Answer 20

capturing carbon dioxide and storing it underground - 90% of industry emissions can be stored like this

Question 21

explain afforestation

Answer 21

planting trees store carbon dioxide due to photosynthesis and release moisture producing clouds which absorb solar radiation

Question 22

benefits to international agreements

Answer 22

agreements to agree on reducing emissions and create a substantial society

Question 23

name the three adaptations of climate change

Answer 23

managing sea levels rising , change agricultural methods and manage water supply

Question 24

how can we adapt to sea levels rising

Answer 24

implement coast defences , houses built on stilts so they are raised above ground , designating areas that cant be used for living , bunds to slow down water flow and trap sediment

Question 25

how can we change agricultural systems to adapt to climate change

Answer 25

use irrigation and resistant crops for maximum crop yield , educating farmers and water harvesting , use technology due to the distribution of pest and irregular rainfall patterns making areas unsuitable for crop growth and extreme weather hazards
