What is a doline in geology?

A doline (or sinkhole as it is more commonly called in North America) is a natural enclosed depression found in karst landscapes. Dolines are the most common landform in karst areas. They are described as small to medium sized closed depressions, ranging from metres to tens of metres in both diameter and depth.

What is a solution doline?

Solution dolines develop in the uppermost weathered zone of the karst rock, termed the epikarst or subcutaneous zone. Drainage within that zone is achieved by leakage of water down fissures such as joints and faults.

Is geology a science?

Geology is the science that studies the Earth’s physical structure and substances, the history of rocks, the processes that act on them and the most economic way to use the world’s resources. Geology involves methods and knowledge from biology, chemistry, physics and mathematics.

What is Lapies geography?

Lapies, also termed as Lapiaz, is a weathered limestone surface. When water flows over a surface having limestone along with other hard rocks, lapies are formed. Such topography is known as lapies. Their grooves vary in depth from a few millimeters to meters.

Who are called geologists?

A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, although backgrounds in physics, chemistry, biology, and other sciences are also useful.

Why is geology not a science?

Don’t believe the idea that geology isn’t a “real science”. It is really all sciences. It is about process: The modern field of geology explores how the planet (and beyond) works. That means that geologists of all flavor study what are the processes that shape the interior and exterior of the Earth.

What are horns and serrated ridges?

Horns form through headward erosion of the cirque walls. If three or more radiating glaciers cut headward until their cirques meet, high, sharp-pointed and steep-sided peaks called horns form.

Which of the following sentences best define the term Lapies?

A small to medium sized shallow depression. A landform whose opening is more or less circular at the top and funnel-shaped towards bottom.

What does doline mean in geography?

Dolina (singular), or doline (plural) translates into a valley (see deffinition by Wikipedia): A valley is a low area between hills or mountains typically with a river running through it. In geology, a valley or dale is a depression that is longer than it is wide.

What is the diameter of a doline?

The diameter ranges from a few to many hundreds of meters. The name doline comes from dolina, the Slovenian word meaning valley . So this was originally a colloquial Slovenian word which was used by the geologists to describe a geologic feature.

How do you form a doline?

Dolines can form by one or a combination of mechanisms, e.g., by enhanced dissolution through focusing of drainage, by collapse into a cavity beneath, or by downwashing of a weakly consolidated soil or sediment cover into cavities beneath (Figure 5).

What is a subsidence doline?

A subsidence doline is a closed surface depression in the form of a solution doline, but in a sediment cover of carbonate rock. It is developed by evacuation (suffosion) of sediment cover downward into a karst void underneath. The result is rapid or gradual subsidence of the surface.
