reaction with OH, dryland soils

Question 4

Sources of Methane

Answer 4

Question 5

Terrestrial sources of N2O

Answer 5

denitrificiation, biomass burning, fossil fuel combustion,

soil microorganisms, nitrifying bacteria

Question 6

Sinks of N2O

Answer 6

Reacting with activated oxygen in the atmosphere.

Question 7

Why are tropical forests rich in nutrients?

Answer 7

The high temperature and moisture of tropical rainforests cause dead organic matter in the soil to decompose more quickly than in other climates, thus releasing and losing its nutrients rapidly.

Question 8

Controls on Isoprene emissions (3)

Answer 8

Light levels, biosynthetic rates, temperature

Question 9

Controls on terpenes emissions (2)

Answer 9

Temperature, the gradient between leaf and air (controlled by vapor pressure of monoterpenes)
