Sinkholes, dolines, uvalas, lapies, and caves are all features that form when the ground dissolves. The type of feature that forms depends on the type of rock that is dissolving, the rate at which it is dissolving, and the presence of groundwater.
Sinkholes are the most common type of feature that forms when the ground dissolves. They are formed when the ground surface collapses into a void that has been created by the DissolutionDissolution of limestone or other soluble rock. Sinkholes can range in size from small, bowl-shaped depressions to large, gaping holes that can swallow entire buildings.
Dolines are similar to sinkholes, but they are larger and more complex. They are formed when multiple sinkholes merge together, or when a sinkhole develops in a layer of rock that is overlain by a layer of less soluble rock. Dolines can be several hundred feet across and can have vertical walls that drop hundreds of feet.
Uvalas are even larger than dolines, and they are often interconnected with one another. They are formed when multiple dolines merge together, or when a doline develops in a layer of rock that is overlain by a layer of very soluble rock. Uvalas can be several miles across and can have vertical walls that drop several hundred feet.
Lapies are small, irregular pits that form on the surface of limestone or other soluble rock. They are formed by the dissolution of the rock by rainwater, which is slightly acidic. Lapies can be a few inches across, or they can be several feet across.
Caves are formed when the dissolution of rock creates a large void below the ground surface. Caves can be very large, and they can have complex networks of passages. Caves are often formed in limestone, but they can also form in other types of rock, such as sandstone and dolomite.
The dissolution of rock is a natural process that has been occurring for millions of years. It is a slow process, but it can have a significant impact on the landscape. Sinkholes, dolines, uvalas, lapies, and caves are all features that form when the ground dissolves. The type of feature that forms depends on the type of rock that is dissolving, the rate at which it is dissolving, and the presence of groundwater.
Sinkholes
- What is a sinkhole?
A sinkhole is a depression in the ground that forms when the land above an underground cavity collapses. - How do sinkholes form?
Sinkholes can form when there is a loss of support in the ground, such as when water dissolves limestone or when SoilSoil is removed. - What are the dangers of sinkholes?
Sinkholes can be dangerous because they can swallow cars, houses, and even people. They can also damage InfrastructureInfrastructure, such as roads and bridges. - How can sinkholes be prevented?
Sinkholes can be prevented by avoiding activities that can cause them, such as removing soil or drilling into the ground.
Dolines
- What is a doline?
A doline is a type of sinkhole that is formed when the ground above an underground cave collapses. - How do dolines form?
Dolines form when there is a loss of support in the ground, such as when water dissolves limestone or when soil is removed. - What are the dangers of dolines?
Dolines can be dangerous because they can swallow cars, houses, and even people. They can also damage infrastructure, such as roads and bridges. - How can dolines be prevented?
Dolines can be prevented by avoiding activities that can cause them, such as removing soil or drilling into the ground.
Uvalas
- What is an uvala?
An uvala is a type of sinkhole that is formed when several dolines merge together. - How do uvalas form?
Uvalas form when there is a loss of support in the ground, such as when water dissolves limestone or when soil is removed. - What are the dangers of uvalas?
Uvalas can be dangerous because they can swallow cars, houses, and even people. They can also damage infrastructure, such as roads and bridges. - How can uvalas be prevented?
Uvalas can be prevented by avoiding activities that can cause them, such as removing soil or drilling into the ground.
Lapies
- What is a lapiaz?
A lapiaz is a type of sinkhole that is formed when water dissolves limestone. - How do lapiaz form?
Lapies form when water flows over limestone and dissolves it. This can happen over a long period of time, or it can happen quickly if there is a lot of rain. - What are the dangers of lapiaz?
Lapies can be dangerous because they can cause the ground to collapse. They can also damage infrastructure, such as roads and bridges. - How can lapiaz be prevented?
Lapies cannot be prevented, but they can be mitigated by avoiding activities that can cause them, such as removing soil or drilling into the ground.
Caves
- What is a cave?
A cave is a natural opening in the ground that is large enough for a person to enter. - How are caves formed?
Caves are formed by the erosion of rock, usually by water. - What are the dangers of caves?
Caves can be dangerous because they can be flooded, they can collapse, and they can contain poisonous gases. - How can caves be explored safely?
Caves should only be explored by experienced cavers who have the proper equipment and training. A large hole in the ground that forms when the ground above a cave or cavern collapses is called a:
(A) sinkhole
(B) doline
(CC) uvala
(D) lapieA depression in the ground that is caused by the collapse of limestone bedrock is called a:

(A) sinkhole
(B) doline
(C) uvala

(A) sinkhole
(B) doline
(C) uvala
