  1. 1Geographic themes — Option A: FreshwaterAt any moment, rivers hold only about 0.006% of Earth's fresh water. So how does a river keep flowing through weeks without rain?Start →
  2. 2Geographic themes — Option B: Oceans and coastal marginsThe Gulf Stream carries more water than all the world's rivers combined. Is that why north-west Europe has mild winters?Start →
  3. 3Geographic themes — Option C: Extreme environmentsAntarctica is covered in ice, yet it counts as a desert. How?Start →
  4. 4Geographic themes — Option D: Geophysical hazardsThe Atlantic is about 2.5 cm wider every year. What moves the plates?Start →
  5. 5Geographic themes — Option E: Leisure, tourism and sportUK 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?Start →
