chemistry of atomosphere

Question 1

early Earth’s atmosphere is believed to mostly consist of 3 gases what were they?

Answer 1

carbon dioxide
nitrogen
water vapour

Question 2

why was there a lot of co2 nitrogen and water in the Earth’s early atmosphere

Answer 2

due to volcanic activity

Question 3

how did the co2 decrease in the atmosphere (3)

Answer 3

carbon dioxide was likely dissolved into the oceans formed then into sediments,rocks and fossil fuels

plants and algae converted co2 into oxygen through photosynthesis

Question 4

3 green house gases

Answer 4

water vapour
carbon dioxide
methane

Question 5

green house effect

Answer 5

this is what keeps the earth warm

green house gases absorb long-wavelength radiation reflected of the surface of the eart

Question 6

carbon footprint

Answer 6

the measure of how much co2 is released into the atmosphere as a result of your actions

Question 7

global warming

Answer 7

the rise in global temperatures

Question 8

ways to reduce carbon footprint as an individual

Answer 8

walking short distances or cyclcing
planting trees
reducing air travel
Using public transport

Question 9

problem of nitrogen oxides

Answer 9

cause respiratory/breathing problems

Question 10

sulphur dioxide issues

Answer 10

cause acid rain which corrodes metals and erodes stone

Question 11

carbon monoxide issues

Answer 11

bind to haemoglobin reducing oxygen they are able to transport round the body

Question 12

why is carbon monoxide dangerous

Answer 12

it is colourless and odourless making it hard to detect

binds with haemoglobin reducing oxygen they are able to transport round the body
