Karst Landscapes and Limestone Features

The video explains karst landscapes, focusing on limestone areas where soil has been removed, exposing the rock to chemical weathering. It describes the carbonation process, where rainwater forms carbonic acid that dissolves limestone, creating features like pavements, caverns, stalactites, and stalagmites. Examples from County Clare and Tipperary illustrate these formations.

What is a karst landscape primarily composed of?

• Sandstone

• Limestone

• Basalt

• Granite

Which process involves rainwater forming a weak acid that dissolves limestone?

• Oxidation

• Hydration

• Carbonation

• Erosion

What characteristic of limestone allows water to pass through it?

• Porosity

• Density

• Impermeability

• Hardness

What are the vertical joints in a weathered limestone pavement called?

• Crevices

• Grikes

• Clints

• Fissures

What underground features can rivers create as they flow through limestone?

• Plains

• Caverns

• Valleys

• Mountains

What forms when calcite deposits build up from the roof of a cave?

• Pillar

• Stalagmite

• Stalactite

• Column

What is the result when a stalactite and stalagmite meet?

• A grike

• A sinkhole

• A limestone pillar

• A new cave

Which of the following is an example of a location with many stalactites and stalagmites?

• The Burren
