  3. Depositional landfornm Depositional landforms These are formed as river now enters into plateaus and mostly plains Stream velocity reduces and channel load increases Alluvial fans and cones: formed at the foot hill zone When streams flowing from higher levels break into foot slope plains of low gradient.


  4. Depositional landfornm Depositional landforms Flood plains are major landforms of river deposition. Formed due to extensive deposition of the sediments at the either side of a river channel during floods . Meander is not a landform but is only a type of channel pattern Curved or zig zag coarse of streams of a river channel in the plains


  5. Depositional landfornm Depositional landforms ox bow lakes formed due to shortening of the meander coarse of a river Natural levees: Low lying sandy ridges along a bank of a river . Formed due to deposition of sediments Protect the areas from floods


  6. Depositional landfornm Depositional landforms li alluvial fans but develop at a different location Deltas are like alluvial fans but develop at a different location Streams essentially now engage only in deposition. Found near the sea Formed when the streams deposit sediments inside the channel As energy is less, river cant penetrate through the deposition and # - acquire the shape of a triangle Agriculturally prosperous Different shapes
