A: Thematic maps are special maps prepared to show the distribution of various variables in a region, such as temperature, rainfall, population, etc. They use statistical data to display patterns of dist

A: The three main methods are: 1) Dot method - uses dots to show distribution of variables that can be counted, 2) Choropleth method - uses color shades or patterns to show data, 3) Isopleth method - use

A: The dot method uses statistical data gathered through counting only. It is suitable for variables that are freely scattered across the region, such as population distribution, distribution of cattle,

A: Endogenetic movements are internal movements that occur within the Earth's interior, particularly in the upper layer of the mantle. These movements are caused by tremendous energy released by radioact

A: Based on velocity, internal movements are classified into: 1) Slow movements - occurring continuously like formation of mountains and continents, 2) Sudden movements - occurring as events like earthqu

A: Orogenic movements are mountain-building movements. They create fold mountains (like the Himalayas) when horizontal pressure causes rock layers to fold, and block mountains (like Meghalaya Plateau) wh

A: Exogenetic processes are external processes that occur on the earth's surface due to forces like solar energy, gravitational force, and kinetic energy. These processes include weathering, erosion, tra

A: Primary and secondary landforms are formed due to internal movements (e.g., continents, mountains, plateaus, plains). Tertiary landforms are formed due to external processes like weathering, erosion,

A: Weathering is the breaking or weakening of rocks due to natural phenomena. It is the process by which rocks are broken down into smaller particles without being moved from their original location.
