A sinkhole is any hole in the ground created by subterranean erosion or solution of rock due to the activity and drainage of water. They can be just a few feet across or large enough to swallow whole buildings.
There are two types - those that form slowly starting with gradual subsidence and those that form suddenly by catastrophic collapse of cavern roofs.
They are common in wet climates where the subsurface rocks are soluble (gypsum/dolomite/limestone).

What is the MAIN features of arthropoD?
An arthropod's main features are the segmented body, an exoskeleton made from chitin, and joint appendages.

Why are there so many sinkholes in Florida?
Florida has many sinkholes due to its unique geological composition, primarily made up of porous limestone that is easily eroded by water. The state's high water table and frequent rainfall contribute to this process, as groundwater dissolves the limestone and creates voids underground. When these voids become too large to support the overlying soil and rock, they collapse, forming sinkholes. Additionally, human activities like drilling, construction, and changes in drainage patterns can exacerbate the occurrence of sinkholes.
How does sinkholes affect the surface of the earth?
Sinkholes can significantly alter the surface of the Earth by creating sudden depressions or holes in the ground, which can range in size from a few feet to several hundred feet across. They occur when underground cavities, often formed by erosion or the dissolution of soluble rock, collapse. This can lead to damage to infrastructure, such as roads and buildings, and disrupt local ecosystems. Additionally, sinkholes can affect groundwater flow and quality, posing risks to nearby water supplies.
What is a Solution Valley?
Several sinkholes merging to create a larger depression called a solution valley.
What are the three features that characterize Karst topography?
The three features that characterize Karst topography are sinkholes (depressions in the ground), caves and underground drainage systems (such as caverns and disappearing streams), and dolines (closed depressions similar to sinkholes but shallower).
What are two features form by under ground weathering?
Two features formed by underground weathering are caves and sinkholes. Caves are formed through the dissolution of limestone by groundwater, while sinkholes are created when the roof of a cave collapses, causing a depression on the surface.
What are two features that are formed by underground weathering?
Two features formed by underground weathering are caves and sinkholes. Caves are formed by the dissolution of limestone or other soluble rocks, creating underground chambers and passages. Sinkholes are depressions in the ground that form when the roof of an underground cavern collapses.
Which features are common in areas of karst topography?
Common features in karst topography include sinkholes, caves, underground rivers, and disappearing streams. Karst landscapes are characterized by the dissolution of soluble rocks such as limestone, resulting in unique surface and subsurface landforms.
What are some features formed by underground erosion and deposition?
Some features formed by underground erosion and deposition include caves, sinkholes, underground rivers, karst landscapes, and stalactites/stalagmites. These formations are typically found in areas with soluble rock formations such as limestone, where water can dissolve the rock over time and create unique underground features.
What common features in karst topography are present?
Common features in karst topography include sinkholes, caves, disappearing streams, underground drainage systems, and limestone pavements. Karst landscapes are characterized by the dissolution of soluble rocks such as limestone, dolomite, and gypsum, resulting in unique landforms and drainage patterns.
Are sinkholes predictable?
Sinkholes can sometimes be predicted based on certain geological features or history of the area. However, in many cases, sinkholes can still occur without warning, making them difficult to predict with complete certainty. Regular monitoring of geological conditions can help in identifying and potentially mitigating the risk of sinkhole formation.
True or false- an area where sinkholes are common is said to have karst topography?
True. Karst topography is characterized by areas where soluble bedrock, such as limestone, is dissolved by groundwater, leading to the formation of sinkholes, caves, and other unique landscape features.
Which landforms is characteristic of an area with karst topography?
Sinkholes are characteristic of areas with karst topography. Karst topography is formed by the dissolution of soluble rocks such as limestone, resulting in features like sinkholes, caves, and underground drainage systems.
What landforms are made by ground water erosion?
Groundwater erosion can create landforms such as caves, sinkholes, and karst topography. As water dissolves and transports soluble rocks like limestone, it can form underground caverns and passages. Over time, these features can collapse, creating sinkholes on the surface. Karst topography is characterized by unique surface features like sinkholes, disappearing streams, and springs, all formed by groundwater erosion in soluble rocks.
If many lakes in Florida are sinkholes?
Yes, many lakes in Florida are indeed sinkholes due to the state's unique geology, which includes a limestone bedrock that is prone to erosion. Over time, the dissolution of limestone by acidic water can create underground cavities, leading to collapses that form sinkholes. These sinkholes can fill with water, creating lakes. Florida's high water table and frequent rainfall further contribute to the formation of these features.
What is a type of landscape in which caves deep valleys and sinkholes called?
The question could also be asked: In an area dominated by sinkholes, the sinkholes can dominate the landscape to produce a series of pits with occasional spires of undissolved rock. This type of landscape is called? Same answer below: KARST - from the Slovenian word "kras" for the type-area.
