A Sinkhole Is Evidence Of What Process In The Landscape?

Answer:

A sinkhole is a hole in the ground that forms when water dissolves surface rock. Often, this surface rock is limestone, which is easily eroded, or worn away, by the movement of water. In a landscape where limestone sits underneath the soil, water from rainfall collects in cracks in the stone.

Frequently Asked Questions

What is a sinkhole evidence of?

Some of the warning signs that can signify that there is a sinkhole include structural cracks in floors and walls, windows and doors that do not close properly and cloudy or muddy well water.

What landscape is a sinkhole?

KarstKarst Features and Landforms Karst is a landscape of sinkholes, sinking streams, caves, springs, and other characteristic features.

What type of geologic conditions does a sinkhole occur?

Solution sinkholes occur in areas where limestone is exposed at land surface or also is covered by thin layers of soil and permeable sand. Dissolution of the limestone or dolomite is most intensive where the water first contacts the rock surface.

Are sinkholes an example of chemical weathering?

Sinkholes are examples of chemical weathering. They are formed when carbonate rocks such as limestone, as well as salt beds are eroded by the water,...

What makes a sinkhole in the ground form?

In a landscape where limestone sits underneath the soil, water from rainfall collects in cracks in the stone. These cracks are called joint s. Slowly, as the limestone dissolves and is carried away, the joints widen until the ground above them becomes unstable and collapses.

How big does a sinkhole have to be?

But often sinkholes can be only a few metres in diameter. They are usually the result of what are known as Karst processes. They happen when a layer of rock underneath the ground is dissolved by acidic water.

How are sinkholes related to land use practices?

New sinkholes have been correlated to land-use practices, especially from groundwater pumping and from construction and development practices. Sinkholes can also form when natural water-drainage patterns are changed and new water-diversion systems are developed.

What do sinkholes and caverns have in common?

Sinkholes are common where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by groundwater circulating through them. As the rock dissolves, spaces and caverns develop underground.
