How Polje is formed?
polje, (Serbo-Croatian: “field”), elongated basin having a flat floor and steep walls; it is formed by the coalescence of several sinkholes.
What is the meaning of Polje?
Definition of polje : an extensive depression having a flat floor and steep walls but no outflowing surface stream and found in a region having karst topography (as in parts of Yugoslavia)
How are Karsts formed?
Karst is associated with soluble rock types such as limestone, marble, and gypsum. In general, a typical karst landscape forms when much of the water falling on the surface interacts with and enters the subsurface through cracks, fractures, and holes that have been dissolved into the bedrock.
How lappies are formed?
lapiés, also spelled Lapiaz, weathered limestone surface found in karst regions and consisting of etched, fluted, and pitted rock pinnacles separated by deep grooves. This rugged surface is formed by the solution of rock along joints and areas of greater solubility by water containing carbonic and humic acids.

How was the Cockpit Country in Jamaica formed?
The formation of Cockpit Country started about 15 million years ago when Jamaica emerged from the sea. The faulted limestone plateau rose to about 600m (2,000ft) above sea level. Erosion of this plateau formed the regular array of round-topped, conical hills and sinks that is the type location for cockpit karst.

What are Karsts made of?
Karst is an area of land made up of limestone. Limestone, also known as chalk or calcium carbonate, is a soft rock that dissolves in water.
What does a karst look like?
karst, terrain usually characterized by barren, rocky ground, caves, sinkholes, underground rivers, and the absence of surface streams and lakes. It results from the excavating effects of underground water on massive soluble limestone.
How caves are formed Upsc?
Swallow Hole in Section – When the stream of groundwater/surface water disappears in the hole; it is called a swallow hole. It is also called ‘Ponor’, and ‘Serbo-Coat. ‘ Cave in Section – Due to the erosion caused by either running water or surface water, a cavity is formed in the rock which transforms into a cave.
What is Uvalas in geography?
Uvala is originally a local toponym used by people in some regions in Slovenia, Croatia, Bosnia and Herzegovina, Montenegro and Serbia. In geosciences it denotes a closed karst depression, a terrain form usually of elongated or compound structure and of larger size than that of sinkholes.
What are Poljes useful for?
The Dinaric Karst has many poljes. They are mostly distributed in subtropical and tropical latitudes but some also appear in temperate or, rarely, boreal regions. Usually covered with thick sediments, called “terra rossa”, they are used extensively for agricultural purposes.
Why is it called Cockpit Country Jamaica?
about. Often regarded as Jamaica’s most inhospitable region, the Cockpit Country is a hilly and dense area with limestone denudations traversing three parishes and covering over 500 square miles. The so-called “cockpits” are caused because limestone, the predominant soil in the area, does not retain water.
Do disappearing streams really disappear?
Disappearing streams will often continue flowing underground and may resurface at another location downstream from where they disappeared. Karst springs are locations where groundwater emerges from the limestone and flows across the surface forming a stream or contained pool.
How much of the US is karst?
In summary, about 25 percent of the United States is underlain by rocks and sediments of all types having karst or pseudokarst features or a potential for them.
How blind valley is formed?
A blind valley is a composite surface feature of the karst cycle consisting of a normal river valley in impermeable sediments and its continuation in permeable rocks where the stream (or river and likewise the valley) abruptly ends in a depression or sinkhole.
Is landforms important for UPSC?
Different landforms of the earth and their evolution are very important topics for the Geography section of the UPSC Syllabus.
