GGH3701 ASSIGNMENT 2 REVISION QUESTIONS WITH 100% ACCURATE
ANSWERS | UPDATED AND VERIFIED
Read the following statement and indicate whether it is TRUE or FALSE:
Improvements in fishing methods result in greater numbers and varieties
(sizes and species) of fish being caught, but fishing in the Southern African
region remains sustainable and no overfishing is taking place.
False ✔
Read the following:
Members of a growing settlement near St. Lucia in South Africa have
observed that the estuary has dried up; in fact, the estuary has been
permanently cut off from the sea. Sightings of some endemic estuarine
organisms have also decreased, and it seems that the whole estuary has been
lost.
Evaluate and select the primary cause for this observation.
1. Shipping and transportation of goods
2. Periodic extended droughts
3. Increased freshwater needs owing to coastal developments
4. Increased freshwater pollution from various settlements
3. Increased freshwater needs owing to coastal developments ✔
Durban Bay located in the eThekwini municipality has become physically
vulnerable especially after April 2022 primarily due to --- and ---.
1. increased flooding; accelerated erosion
2. increased agriculture; economic growth
3. mineral exploration; shipping
4. pollution; decreased rainfall
Increased flooding; accelerated erosion ✔
Read the following:
An urban settlement with surrounding agricultural areas is located upstream
of an estuary. The urban settlement has been growing quite rapidly and there
is pressure on agricultural activities to sustain the growing human population.
, An estuary located downstream is consequently negatively affected - the
estuary mouth has closed permanently.
Evaluate and select which ONE of the following puts the biggest pressure on
the estuary?
1. Rapid rate of soil erosion
2. Loss of fish species
3. Oil pollution from shipping
4. Human health issues
1. Rapid rate of soil erosion ✔
Read the following:
Recent reports focused on the assessment of water quality of some of South
Africa's major beaches. The reports have shown a general downward trend in
the standard of water quality especially in regions which have experienced
rapid population growth.
Evaluate the given scenario and determine which one of the following is the
primary cause for this observation.
1. Increased shipping and transportation of goods
2. Increased freshwater needs owing to coastal developments
3. Inadequate sewage works and systems
4. More frequent floods and periodic extended droughts
3. Inadequate sewage works and systems ✔
Read the following statement and indicate whether it is TRUE or FALSE:
Fertility determines the age structure and age distribution of a population.
True ✔
Which ONE of the following is commonly used to measure the social and
economic impact of age structures in a specific population?
1. Quality of life
