Geography Quiz - Limestone Scenery 03 (Answers)
This is our third KS3 Geography quiz on limestone scenery. Carboniferous and other types of limestone are partially soluble in acid. Carboniferous limestone contains joints and bedding planes and therefore forms many erosional landforms. These include limestone pavements, pot holes, caves and gorges. Where water drips into a cave from above, each drop leaves behind a small amount of the calcium carbonate that it has dissolved on its journey through the limestone, forming a stalactite. Where the drop lands, it can leave behind even more, forming a stalagmite.
In the UK, Carboniferous limestone is found mainly in the northern areas of England - the Peak District, the Yorkshire Dales and the north Pennines are three key areas. The limestone scenery of these areas attracts many tourists. Limestone soils tend to be thin and not particularly fertile. They are usually upland areas too, so sheep farming is the most usual form of agriculture. Limestone is an incredibly important rock and is used in the manufacture of hundreds of common everyday items. This means that it is quarried in large quantities.

If you visit the Yorkshire Dales, you might cross or walk beside such streams as Tang Hall Beck or Osbaldwick Beck!

Surface streams on limestone are mildly acidic due to this acid

As a drop of water evaporates, it cannot hold as much dissolved material

It is sometimes spelled as grike. Grykes can sometimes be as wide as half a metre but are often narrower

Sometimes called sink holes

Water freezes and expands to widen the cracks

In very old caves, there are some spectacular examples of columns

In the winter, the river Lathkill in Derbyshire is fed by a large resurgent stream in a cave in the side of its valley. During the summer, the cave is dry and the upper part of the river disappears as well. The summer resurgent is much less spectacular and is spread over a distance of several hundred metres

These are cracks that formed as the sediments turned into rock
