Summary of Exogenetic Processes Part-2 for Maharashtra Board Class 9 Geography. Key concepts, important points, and chapter overview.
Overview
Exogenetic processes are external forces that continuously shape and modify Earth's surface through erosion, transportation, and deposition. In this chapter, we study how different agents like rivers, glaciers, wind, sea waves, and groundwater create various landforms through their continuous work.
Key Concepts
