Question 1

What could an increase in global temperatures lead to?(part1)

Answer 1

Polar ice caps melting-causing a rise in sea level
Increased flooding in coastal area and coastal erosion

Question 2

What could an increase in global temperatures lead to?(part2)

Answer 2

Changes in rainfall patterns-May cause too much or too little water.

Question 3

Why are green house gases dangerous

Answer 3

They act like an insulating layer in the earths atmosphere-causes the earth to warm up

Question 4

How can deforestation lead to the greenhouse effect

Answer 4

fewer trees means less CO2 is removed

Question 5

How does the burning of fossil fuels lead to the greenhouse effect

Answer 5

Carbon that was locked up is released as co2

Question 6

How can creating waste lead to the greenhouse effect

Answer 6

More landfill sites and more waste from agriculture=more CO2 and Methane

Question 7

How can agriculture lead to the greenhouse effect?

Answer 7

more farm animals=more methane

Question 8

What could an increase in global temperatures lead to?(part3)

Answer 8

Frequency and severity of storms may increase

Question 9

What could an increase in global temperatures lead to?(part4)

Answer 9

Changes in temperature in areas leading to differences in the habitats of wild species

Question 10

why is the greenhouse effect necessary for life

Answer 10

It is a natural phenomenon
Without it, earth would be too cold to live on

Question 11

How have Human activities led to an increase in greenhouse gases

Answer 11

Carbon dioxide-Combustion and deforestation
Methane-increased farming and decomposition of animals
