Diagrams and examples from India and Asia.

(viii) Glacial processes and associated landforms.
Continental and mountain or valley glaciers, processes of glacial erosion – plucking, abrasion, attrition; erosional features, e.g. cirque and its components, U shaped and hanging valleys, roche moutonnes, depositional formations, moraines of various types. Some Indian glaciers - Siachen, Gangotri, Baltoro. Diagrams and examples from India.

(ix) Work of ground water and associated landforms. Water Conservation.
Definiton of ground water, watertable, acquifers, springs. Process of erosion by groundwater solution, corrasion. Features formed by underground water (karst topography) – sink holes, dolines, caves, caverns, karst lakes, depositional features – stalactites, stalagmites, cave pillars, dripstones: their formation. Diagrams and examples from India and Australia.

(x) Marine processes and associated landforms.
