Environmental Change and Management
Summary Questions and answers
Atmosphere - correct answer-The envelope of gases on planet earth
Lithosphere - correct answer-The rocks, soils, sand and other abiotic components of the
earth's crust
Hydrosphere - correct answer-All the water on earth includes rivers, lakes, oceans, glaciers
etc. water table
Biosphere - correct answer-All living things e.g. plants
Source: - correct answer-The 'source' function of the environment is its ability to supply the
food and materials on which we depend
Sink - correct answer-The 'sink' function of the environment is its ability to break down,
recycle or absorb wastes
Service - correct answer-The 'service' function of the environment is the processes that
support our life without requiring human action to produce them
Spiritual - correct answer-The 'spiritual' function of the environment is its recreational,
psychological aesthetic and spiritual value to people
The Carbon Cycle - correct answer-
The Carbon Cycle
List the places where carbon is found on Earth - correct answer-Air, Vegetation, Humans,
Animals and River systems
The Carbon Cycle
Why carbon is important and why carbon is sometimes hazardous? - correct
answer-Provides fuel/food for vegetation to produce CO2 basis for building blocks of all
organic life. Too much carbon act as a temperature trap for the atmosphere (insolation).
Dissolves into the ocean which increases the acidity in the water.
The Carbon Cycle
What would happen if we burned more fossil fuels? - correct answer-Increased CO2 =
magnification of the above issue
The Hydrological Cycle - correct answer-
, The Hydrological Cycle
List the places where water is stored on Earth - correct answer-Flora, fauna, surface water,
ice, glaciers, polar regions, ground water, sea and oceans.
The Hydrological Cycle
Identify and describe how water is transferred between different stores - correct
answer-Sunlight --> leads to a change in state from liquids (evaporation) to condensation
(clouds & precipitation --> rainfall
The oxygen cycle - correct answer-
Describe how the oxygen cycle works within our natural environment - correct answer-The
oxygen cycle works whereby the vegetation component of the biosphere extracts carbon
from the atmosphere, uses it as the building blocks of its structure (tree-trunk and leaves)
and they respire out.
An example of the source, sink, service and spirituality function of the River Ganges
Source: - correct answer-Drinking, washing and bathing
· Facilitates the movement of food and goods along river
· Hydroelectric power stations have been built e.g. Farakka Barrage
· Provides transport route for many water vessels
An example of the source, sink, service and spirituality function of the River Ganges
Sink - correct answer-· Ecosystems along the river can help reduce the impacts of floods
and droughts
· The river is used to deposited ashes from cremations sewage, toxic waste from
· industry and mining, and run off from fertilisers and pesticides used in farming
An example of the source, sink, service and spirituality function of the River Ganges
Service - correct answer-· Precipitation in the form of snow forms glaciers, e.g. the Gangtori
Glacier which melts and helps form the river
· From June to September, the south-west monsoon brings 84% of precipitation to the area,
which helps form the river
· Melted snow from high mountain peaks, e.g. Nanda Devi helps form the river
· The river starts in the western Himalayan Mountains at 3900 metres
· Supports biodiversity of fish and birds
· Distributes fertile soil and during periods of flooding
An example of the source, sink, service and spirituality function of the River Ganges
Spirituality - correct answer-· 2,000,000 people ritually bathe in the river every day
· The Ganges is a sacred river to Hindus, who call the river Mother Ganga
