I studied Geog for A levels. But that was the old syllabus last year.
Some of the examples include:
Physical

-Theory of Plate Tectonics
-Weathering
-Formation and identification of different types of Volcanoes
-Weather systems
-Hydrology
-Aridity of landscapes
-The Earth's oscillation around the sun and how it affects Earth atmosphere and landscape.
Human

-Urbanization
-Gentrification
-Different types of urban models
-Tourism
-Population
-Economic Geog
Believe me, it's harder than it sounds really.
