Limestone Flashcards
(19 cards)
Horizontal layers of limestone representing layers of sediment over time
Bedding Plane
Calcium Carbonate Deposits that grow downwards and hang from cave ceilings
Stalactite
Calcium Carbonate Deposits that grow upwards from the floor of a cave
Stalagmite
Depression on the surface of a limestone landscape, often leading to a cave
Pothole
A depression in the ground where surface water disappears down onto an underground drainage system, often a network of caves
Swallow Hole (Sinkhole)
The primary mineral component of limestone
Calcite
When stalactites and stalagmites grow together they form a pillar like structure
Limestone Column
Any Substance which, when dissolved in water, has a Ph greater than 7
Alkali
Any Substance which, when dissolved in water, has a Ph less than 7
Acid
The chemical composition of limestone
Calcium Carbonate
A type of limestone normally occurring in thick beds, formed in the Carboniferous period
Carboniferous Limestone
The process of weathering in which limestone rock is dissolved by acidic rain
Chemical solution
The process by which rocks are decomposed, dissolved or loosened by chemical means
Chemical weathering
Solid Blocks of rock that make up limestone pavements
Clints
The cracks between the Clints in limestone pavement, formed by chemical solution
Grykes
A sedimentary rock, formed by deposits of marine creatures
Limestone
A surface area of limestone weathered in such a was as to form Clints and grykes
Limestone Pavement
The natural decomposition of rocks into smaller particles over time
Weathering
An area in North West Yorkshire, where underlying rock is principally Carboniferous limestone
Yorkshire Dales
