7.3 Deforestation and Peat Bogs

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
