GCSE Geography 3 — Questions and Answers
Question 1: What is the name for the curved ridge of deposited material that forms across a bay?
- Spit
- Stack
- Bar (Correct answer)
- Tombolo
Correct answer: Bar
A bar is a ridge of sand or shingle that forms when a spit extends across the full width of a bay, enclosing a lagoon.
Question 2: Which greenhouse gas is primarily produced by livestock and landfill sites?
- Carbon dioxide
- Methane (Correct answer)
- Nitrous oxide
- Water vapor
Correct answer: Methane
Methane (CH₄) is released in large quantities through livestock digestion and the decomposition of organic waste in landfills.
Question 3: In a river's long profile, where does deposition most commonly occur?
- In the upper course where the gradient is steep
- In the middle course at meanders
- In the lower course near the mouth (Correct answer)
- At waterfalls in the upper course
Correct answer: In the lower course near the mouth
Deposition is most common in the lower course where the river slows down as gradient decreases and it approaches the sea.
Question 4: What is a 'corrie' (also called a cirque)?
- A glacially carved valley with a U-shaped cross-section
- An armchair-shaped hollow in a mountainside carved by glacial erosion (Correct answer)
- A ridge formed between two glaciated valleys
- A large flat area deposited by a melting glacier
Correct answer: An armchair-shaped hollow in a mountainside carved by glacial erosion
A corrie is an armchair-shaped hollow high on a mountainside formed by rotational movement of ice eroding the rock.
Question 5: Which of the following best describes a 'trade wind'?
- Winds that blow from the poles toward the equator
- Prevailing winds that blow toward the equator from the subtropical high-pressure zones (Correct answer)
- Seasonal winds driven by temperature differences between land and sea
- Winds generated by low-pressure weather systems
Correct answer: Prevailing winds that blow toward the equator from the subtropical high-pressure zones
Trade winds are persistent winds that blow from subtropical high-pressure belts toward the equatorial low-pressure zone.
Question 6: What does 'infant mortality rate' measure?
- The number of deaths per 1,000 people in a population per year
- The number of deaths of children under 5 per 1,000 births
- The number of deaths of babies under 1 year per 1,000 live births (Correct answer)
- The average number of years a newborn is expected to live
Correct answer: The number of deaths of babies under 1 year per 1,000 live births
Infant mortality rate measures the number of deaths of infants under one year of age per 1,000 live births in a given year.
Question 7: What term describes a river's ability to transport its load?
- Competence
- Capacity (Correct answer)
- Discharge
- Gradient
Correct answer: Capacity
Capacity refers to the total amount of load a river can carry at a given time, determined mainly by its discharge.
