Geography

IB Diploma Geography SL 13 lessons
  1. Geographic themes — Option A: Freshwater At any moment, rivers hold only about 0.006% of Earth's fresh water. So how does a river keep flowing through weeks without rain?
  2. Geographic themes — Option B: Oceans and coastal margins The Gulf Stream carries more water than all the world's rivers combined. Is that why north-west Europe has mild winters?
  3. Geographic themes — Option C: Extreme environments Antarctica is covered in ice, yet it counts as a desert. How?
  4. Geographic themes — Option D: Geophysical hazards The Atlantic is about 2.5 cm wider every year. What moves the plates?
  5. Geographic themes — Option E: Leisure, tourism and sport UK residents made about three times as many trips abroad as Indian nationals did in 2025, yet India has about 21 times as many people. Why?
  6. Geographic themes — Option F: Food and health In 2023 the world's food supply came to about 3,000 calories per person per day. So why did around 645 million people go hungry in 2025?
  7. Geographic themes — Option G: Urban environments In Denmark, 200 people can make a place urban. In Japan it takes 50,000. So how urban is the world?
  8. Core — Unit 1: Changing population Why do more than 9 in 10 people in China live on one side of a single line?
  9. Core — Unit 2: Global climate, vulnerability and resilience In 1991 one volcano in the Philippines cooled the whole planet. How?
  10. Core — Unit 3: Global resource consumption and security In 1990, two in three people in East Asia and the Pacific lived in extreme poverty. By 2025, fewer than 1 in 50 did. So why did the number of extremely poor people in sub-Saharan Africa rise?
