How are Clints and grikes form?
By chemical weathering leaving gaps in the limestone (grykes) and slabs of rock outside them (Clints)
How do grikes form?
Grikes form when limestone is dissolved by water.
Do grikes in limestone form mainly by wind or water?
Grikes in limestone primarily form due to water erosion rather than wind erosion. Water seeping into the limestone gradually dissolves and widens vertical joints and fractures, creating the grikes. Wind can contribute to weathering and desiccation of the limestone, but it is not the primary agent responsible for the formation of grikes.
What sort of rock do you find Clints and grikes?
LIMESTONE

Which of the following is associated with areas of karst topography?
a.) Sinkholes b.) sinking streams c.) caverns d.) all of the above
What are Clints and grikes?
Limestone pavements are made up of two separate but integral parts known as clints and grykes. Clints are the blocks of limestone that constitute the paving, their area and shape is directly dependant upon the frequency and pattern of grykes. Grykes are the fissures that isolate the individual clints.
What is the weathering process called that causes clients and grikes?
Clints and grykes are caused by exposed limestone bedrock being weathered by rainfall over many years.
How do grikes form?
Grikes form when limestone is dissolved by water.

What does solution in geography?
solution is the process by which carbon dioxide is mixed with rain water to form carbonic acid when this carbonic acid reacts with rock such as lime stone it forms a secondary mineral called calcium bicarbonate which is soluble in water and dissolves very quickly, this results in enlarged and deepen joints called grikes within limestone.

What are characteristics of karst topography?
A Karst topography displays a variety of large or small scale features both on the surface and beneath. On exposed surfaces, small features may include flutes, runnels, clints and grikes, collectively called karren or lapiez. Medium-sized surface features may include sinkholes or dolines (closed basins), vertical shafts, disappearing streams, and reappearing springs. Large-scale features may include limestone pavements, poljes and blind valleys. Mature karst landscapes, where more bedrock has been removed than remains, may result in karst towers or haystack/eggbox landscapes. Beneath the surface, complex underground drainage systems (such as karst aquifers) and extensive caves and cavern systems may form.
What is a karst?
A karst topography is that which composes of limestone and its associated features and structures.•Karst topography and caves develop in limestone rocks due to their solubility in dilute acidic groundwater.•The solubility of limestone in water and weak acid solutions leads to karst landscapes.•Regions overlying limestone bedrock tend to have fewer visible above-ground sources (ponds and streams), as surface water easily drains downward through joints in the limestone.•While draining, water and organic acid from the soil slowly (over thousands or millions of years) enlarges these cracks, dissolving the calcium carbonate and carrying it away in solution.•Most cave systems are through limestone bedrock.•Cooling groundwater or mixing of different groundwater will also create conditions suitable for cave formation.Karst topography occurs when the underlying bedrock is dissolved. The bedrock is made of gypsum, limestone or dolomite. This causes sinkholes and caverns to form.
What climates would chemical weathering most readily occur?
Lots of rain, wind, freeze/thaw cycles. Hot, humid climates with high rainfall promote chemical weathering.
