Year 9 Geography Practice Exam Notes

Section I: Multiple Choice Questions

  • Question 1: Definition of a Biome

  • B. A biome is best defined as a region classified by its climate, vegetation, and wildlife.

  • Question 2: Example of a Biome

  • D. A watershed is not an example of a biome.

  • Question 3: Characteristics of a Temperate Rainforest

  • C. Sparse vegetation with few trees is NOT a characteristic of a temperate rainforest.

  • Question 4: Climatic Features

  • B. Temperature, precipitation, and seasonal patterns are examples of climatic features.

  • Question 5: Productivity in a Biome

  • B. Productivity measures the amount of plant and animal life that can grow and be used for agriculture.

  • Question 6: Factors Affecting Productivity

  • C. Climate most directly affects the productivity of a biome.

  • Question 7: Latitude and Climate

  • C. Latitude influences climate by affecting the intensity and concentration of solar energy received.

  • Question 8: Altitude and Temperature

  • B. Temperature decreases with altitude.

  • Question 9: Largest Climate Zone in Australia

  • B. The arid climate zone covers the largest area of Australia.

  • Question 10: Arid Climate in Central Australia

  • B. The distance from the coast reduces moisture from the ocean, contributing to arid climates.

Section II: Short Answer Questions

  • Question 18: Agricultural Yield

  • Definition: The amount of crop that can be grown.

  • Example: A yield of 2000 kg of wheat per hectare.

  • Question 19: Characteristics of ONE Biome

  • Example: Tropical rainforests are characterized by high biodiversity, warm temperatures, and high levels of precipitation, with densely packed trees and a rich understory.

  • Question 20: Latitude Influence on Productivity

  • Latitude affects solar energy received, influencing temperature and moisture levels, which directly impacts plant growth and agricultural productivity.

Section III: Extended Response

  • Question 21: Climatic Zones and Biomes
  • Climatic zones significantly influence biome location. For instance, the Sahara Desert demonstrates this correlation through its extreme temperatures and minimal rainfall leading to a desert biome.
  • Characteristics:
    • Covers 9,200,000 square kilometers – comparable to China or the US.
    • Hottest desert with summer temperatures reaching up to 47 °C and the highest recorded temperature at 58 °C.
    • Very little rainfall, with half receiving less than 1 inch annually.
    • Night temperatures can drop to -6 °C due to low humidity.
    • Diverse landscape includes sand dunes, rocky plateaus, and salt flats shaped by weather extremes

Key Concepts and Definitions

  • Biome: A large ecological area with distinct climate, vegetation, and wildlife.
  • Productivity: The capacity of an ecosystem to produce biomass, influenced by climate, soil, and other environmental factors.
  • Latitude: The distance north or south of the equator, affecting solar energy and weather patterns.
  • Altitude: Height above sea level, affecting temperature and weather conditions.
