Geography IBDP is a part of Individuals and Societies of the IB Curriculum. Being a dynamic subject firmly grounded in the real world, Geography describes and helps to explain similarities and differences between places, on a variety of scales and from various perspectives.

The objective of the curriculum of Geography IBDP is to develop this understanding of the dynamic inter-dependencies of people, spaces and the environment, to develop a critical awareness and complex thinking ability on geographical issues, and understanding and evaluating the need for planning and sustainable development through the management of resources at varying scales. The course integrates physical, environmental and human geography, and students acquire elements of both socio-economic and scientific methodologies. Geography takes advantage of its position to examine relevant concepts and ideas from a wide variety of disciplines, helping students develop life skills and have an appreciation of, and a respect for, alternative approaches, viewpoints and ideas.

This chapter focuses on physical processes and landscapes. Glacial erosion which includes plucking, abrasion, freeze-thaw, weathering, pressure release and meltwaters can produce landforms such as cirques, aretes, peaks, troughs, basins or hanging valleys. It further explains the characteristics of till, moraine, drumlins and erratics. The periglacial environment is a cold climate that is characteristically subject to intense cycles of freezing and thawing of superficial sediments. There are three types of periglacial environments- artic continental, alpine, artic maritime.

There are a number of landforms and processes associated with periglacial environments that include freeze-thaw, mass movements, permafrost, thermokarst, pingos and patterned ground. the lack of sufficient rainfall results in a dry, hot and arid environment that could lead to weathering in deserts via salt crystallization and disintegration. The chapter moves on to discuss the work of water in deserts and classifies rivers in deserts into three categories- exogenous rivers, endoreic rivers and ephemeral rivers. Wind action in desert is also seen in the form of deflation and abrasion. Features of arid landscapes include dunes [can be found in the linear, star, dome, crescentic, and parabolic shapes], zeugen, yardangs, wadis, mesas and buttes.
