Correct Answer - Option 3 : Crickmay
The correct answer is option 3
- The concept of panplain was propagated by Crickmay.
- Crickmay defines ‘Panplain’ as a broad and level surface created by lateral corrasion of rivers leading to the coalescence of adjacent floodplains. Panplains formed by lateral planation by rivers whereas peneplains formed by fluvial action and pediplains formed by retreat of rivers.
- It is an area of very subdued relief that consists of coalesced flood-plains. It is, therefore, owing to lateral stream migration and is a component of a peneplain. Good examples are found in the Carpentaria region of Australia.
Therefore, the correct answer is Crickmay
