B.2.4—Earth’s albedo variation Topic Practice
B.2.4—Earth’s albedo variation Topic Practice
Practise explaining why Earth's albedo is an average quantity by linking it to changing location, cloud cover, season and surface conditions.
How this is tested
- select valid reasons for albedo variation, such as latitude, cloud cover, season or surface type
- distinguish factors that change local solar input or reflectivity from statements that do not affect Earth's albedo
