FAQs on Geography

  1. What is Geography?
  • Geography is the study of the Earth’s physical features, climate, human populations, cultures, and economies, and their interactions. It seeks to understand the spatial patterns and processes that shape our world.
  1. What are the two main branches of Geography?
  • Physical Geography: Focuses on the natural environment and its processes, including landforms, climate, weather, soil, vegetation, and water bodies.
  • Human Geography: Examines the spatial organization of human activities, including population, culture, politics, economics, and urban development.
  1. What are the seven continents?
  • The seven continents are Asia, Africa, North America, South America, Antarctica, Europe, and Australia (Oceania).
  1. What are the five oceans?
  • The five oceans are the Pacific, Atlantic, Indian, Southern, and Arctic Oceans.
  1. What is the difference between latitude and longitude?
  • Latitude: Imaginary lines that run horizontally across the Earth, parallel to the equator, measuring distance north or south of the equator.
  • Longitude: Imaginary lines that run vertically around the Earth, passing through the poles, measuring distance east or west of the prime meridian.
  1. What causes earthquakes?
  • Earthquakes are caused by the sudden release of energy in the Earth’s crust, resulting in seismic waves that shake the ground. They are often caused by the movement of tectonic plates.
  1. What is the difference between weather and climate?
  • Weather: Refers to the short-term atmospheric conditions in a particular place at a particular time, such as temperature, precipitation, humidity, wind, and cloudiness.
  • Climate: Refers to the long-term average weather patterns in a particular region, including temperature, precipitation, and seasons.
  1. What is the greenhouse effect?
  • The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space, and the rest is absorbed and re-radiated by greenhouse gases. These gases trap some of the heat, preventing it from escaping back to space, which helps regulate the Earth’s temperature.
  1. What are the major environmental problems facing the world today?
  • The major environmental problems include climate change, pollution, deforestation, loss of biodiversity, water scarcity, and waste management.
  1. What is the importance of geography?
  • Geography helps us understand the world around us, how it has changed over time, and how human activities are shaping the planet. It provides valuable insights for addressing environmental challenges, managing resources, planning for sustainable development, and understanding different cultures and societies.
