L7 - Better hare than gone Flashcards
What is permafrost
This is when permanently frozen soil remains for a long time so vegetation can’t grow
Describe a natural carbon sink
Plants take in CO2, through photosynthesis, so they act as carbon sinks
What natural disaster releases trapped carbon?
Forest fires
Describe ways in which vegetation disrupts hydrological processes?
Vegetation slows surface run off and through flow, root systems increase percolation rate.
What is sequestration
Taking in substance, drawdown of carbon.
Why does lack of water make decomposition harder?
The nutrients isn’t stored, there aren’t water stores so then natural processes will not occur to let decomposition happen.
What does deciduous mean?
Deciduous means it loses its leaves and coniferous keeps leaves all year round.
What does vegetation slow down?
Surface runoff
What does decomposition do?
More decomposition means that more nutrients is being put back into the soil.
What do root systems increase the rate of?
More decomposition means that more nutrients is being put back into the soil.
What increases the amount of moisture in soil
Organic matter increases the amount of moisture stored in soil
What is transpiration?
When water is transferred from leaves to air
Where are plants requirements stored
400% of requirements of plants are stored underground by plants
Where is methane released from?
Wetlands
What turns Ammonium into Nitrates?
Nitrates
