Gaokao Exam Gaokao Geography: Physical and Human Geography 3 — Questions and Answers
Question 1: Which of the following correctly explains why the Tibetan Plateau has a cold, dry climate despite being located at low latitudes?
- Its distance from the ocean causes extreme continental dryness at all elevations
- Its very high altitude (average 4,500 m) causes low temperatures and rainshadow effects (Correct answer)
- The Himalayan rain shadow blocks moisture from both the Pacific and Indian Oceans
- Cold ocean currents adjacent to the plateau reduce precipitation and temperature
Correct answer: Its very high altitude (average 4,500 m) causes low temperatures and rainshadow effects
The Tibetan Plateau's extreme altitude (mean ~4,500 m) causes temperatures to be far lower than latitude alone would predict; thin air and high albedo from snow/ice also reduce heat retention.
Question 2: Which map projection preserves accurate shapes of small areas but distorts area and distance at high latitudes?
- Peters (equal-area) projection
- Mercator (conformal cylindrical) projection (Correct answer)
- Azimuthal equidistant projection
- Albers equal-area conic projection
Correct answer: Mercator (conformal cylindrical) projection
The Mercator projection preserves local angles and shapes (conformal), making it useful for navigation, but it greatly exaggerates area toward the poles (Greenland appears larger than Africa).
Question 3: The concept of 'sustainable development' as defined by the Brundtland Commission (1987) refers to:
- Economic growth that prioritizes industrial output over environmental concerns
- Development that meets the needs of the present without compromising future generations' ability to meet their own needs (Correct answer)
- Development focused exclusively on renewable energy sources
- Urban development policies that limit suburban sprawl
Correct answer: Development that meets the needs of the present without compromising future generations' ability to meet their own needs
The Brundtland definition of sustainable development balances economic, social, and environmental pillars, recognizing intergenerational equity as a core principle.
Question 4: China's 'Three Gorges Dam' on the Yangtze River has most significantly affected regional geography by:
- Increasing river discharge downstream by releasing more water
- Flooding over 600 km of river valley and forcing relocation of over 1 million people (Correct answer)
- Permanently reversing the direction of the Yangtze River's flow
- Creating a new port city at the dam's location
Correct answer: Flooding over 600 km of river valley and forcing relocation of over 1 million people
The Three Gorges reservoir flooded ancient cities, farmland, and archaeological sites, necessitating the world's largest forced resettlement program of approximately 1.3–1.4 million people.
Question 5: In the context of global energy resources, 'peak oil' refers to:
- The price peak of oil during international supply crises
- The theoretical point at which global oil production reaches its maximum rate before permanently declining (Correct answer)
- The maximum refining capacity of a given country
- The optimal oil production level set by OPEC agreements
Correct answer: The theoretical point at which global oil production reaches its maximum rate before permanently declining
Peak oil (Hubbert's peak) is the point where cumulative production equals half the ultimately recoverable resource, after which production rates inevitably decline due to geological depletion.
Question 6: The term 'urban heat island' (UHI) effect describes the phenomenon where:
- Cities experience more cooling than surrounding rural areas due to air conditioning
- Urban areas are significantly warmer than surrounding rural areas due to human activities and surfaces (Correct answer)
- Industrial areas produce heat islands that warm adjacent agricultural land
- Ocean cities warm faster than inland cities due to sea surface temperatures
Correct answer: Urban areas are significantly warmer than surrounding rural areas due to human activities and surfaces
UHIs occur because urban surfaces (concrete, asphalt) absorb and retain more heat, reduced vegetation limits evaporative cooling, and human activities (vehicles, buildings) release additional heat.
Question 7: In the hydrological cycle, the process by which water vapor is released from plant leaves is called:
- Precipitation
- Infiltration
- Transpiration (Correct answer)
- Condensation
Correct answer: Transpiration
Transpiration is the evaporation of water from plant stomata; combined with soil evaporation, it is often called evapotranspiration and is a major return pathway for water to the atmosphere.
