कारण और संदर्भ

Bangladesh's physiographic divisions are landform regions distinguished by origin, relief, sediment, drainage and surface materials. The governing relationship is: River deposition, erosion, tectonic uplift and older terrace surfaces produce contrasting floodplains, terraces and hill regions.

• Bangladesh's physiographic divisions are landform regions distinguished by origin, relief, sediment, drainage and surface materials.
• River deposition, erosion, tectonic uplift and older terrace surfaces produce contrasting floodplains, terraces and hill regions. Use the barind tract is an older, relatively elevated terrace compared with active alluvial floodplains. as a named application in a comparative answer.

आम गलतफ़हमियाँ

• A physiographic division is based on landform and process, not only administrative boundaries.
• Terraces are older surfaces, not simply any high riverbank.
