Question - Q. Poljes, Uvalas and Dolines are often associated with which one of the following landforms?
Options:
A .  Aeolian erosional landforms
B .  Karst Topography
C .  Fluvial lowland landforms
D .  Landforms of highland glaciation
Answer: Option B
:
B
Explanation:
Poljes, Uvalas, Dolines and Grikes are kind of Karst Topography. Any limestone or dolomitic region showing typical landforms produced by the action of groundwater through the processes of solution and deposition is called Karst topography.
When a number of swallow holes coalesce, a larger hollow is formed called a Doline . Several dolines may merge as a result of subsidence (gradual caving) to form an even larger depression called an Uvula . In Yugoslavia, some very large depressions called Polje may be as large as 100 square miles, but produced partly due to faulting.
