What is a carbon sink?
Something that "locks away" Nitrogen
Something that "locks away" Carbon
Something that "locks away" Oxygen
Something that "locks away" Silver
What is deforestation?
Cutting down a tree
Large scale cutting down of trees
Picking endangered flowers
Taking seeds from a woodland
What are the reasons for deforestation? Tick ALL that apply
To provide timber as a fuel
Because people hate trees
To provide timber as a building material.
To provide extra land to grow crops
To provide extra land to rear animals
Which of these is a consequences of deforestation
Reduces the rate at which carbon dioxide is absorbed and ‘locked away’ in the plant biomass by photosynthesis.
Reduces the rate at which oxygen is absorbed and ‘locked away’ in the plant biomass by photosynthesis.
Reduces the rate at which carbon dioxide is absorbed and ‘locked away’ in the plant biomass by respiration
Reduces the rate at which oxygen is absorbed and ‘locked away’ in the plant biomass by respiration
Which of these is a consequences of deforestation
Forest habitats are destroyed and biodiversity is increased.
More plants
Forest habitats are destroyed and biodiversity is reduced.
more animals
Which of these is a consequences of deforestation
More trees for wood
More different types of cattle
Cattle are often reared on the land, producing methane. Methane, a greenhouse gas, contributes more to global warming than carbon dioxide.
Cattle are often reared on the land, Cattle absorb carbon dioxide through photosynthesis.
What is this a description of?
................is formed in waterlogged, acidic bogs over thousands of years by the growth of mosses and other plants, which absorb and ‘lock away’ carbon dioxide during photosynthesis. When the moss dies, the waterlogged bog provides anaerobic conditions which, together with the acidity of the bog, prevent the total decomposition of the moss. It accumulates in the bogs in a partially-decomposed state, forming ................
Soil
Electricity
Moss
Peat
Why are peat bogs important.
They look good
They are an important nitrate sink,containing more ‘locked-away’ nitrates than the Earth’s forests.
They are an important carbon sink,containing more ‘locked-away’ carbon than the Earth’s forests.
They have the same name as a guy I know
Why are Peat bogs an important resource (tick all that apply).
The amount of biomass it contains means it can be dried and burnt as a fuel.
It can help improve soil structure
It is an important energy source in some countries.
All of the above
Why should we conserve Peat bogs
To slow down the rate of global warming
To conserve biodiversity
Both are correct
