KS3 limestone scenery - all about the sedimentary rock

Geography Quiz - Limestone Scenery 02 (Questions)

This KS3 Geography quiz takes a second look at limestone scenery. Limestone is a sedimentary rock composed largely of the minerals calcite and/or aragonite, which are different crystal forms of calcium carbonate (CaCO₃). Sedimentary rocks are deposited in layers on the beds of oceans, seas, lakes and occasionally on dry land. The breaks between the layers are called bedding planes. They are usually areas of weakness in a mass of rock. Carboniferous limestone is no exception, but not only does it contain bedding planes, it also contains a lot of vertical joints.

Rainwater is slightly acidic and, as you should have learnt in your science lessons, calcium carbonate will dissolve in acids. Rainwater slowly dissolves the vertical joints, widening them and creating a limestone pavement. As the water travels deeper underground, it can still dissolve the limestone, particularly along the bedding planes. This is how caves and caverns are formed. A cave or cavern that is close to the surface of the earth can suffer from a collapsed roof, creating a deep and steep-sided limestone gorge.

Geography Quiz - Limestone Scenery 02 (Answers)

Gordale Scar in Yorkshire is an example of what?

[x]	A gorge
[ ]	A limestone pavement
[ ]	A stalactite
[ ]	A swallow hole

It's approximately 15-16 million years old

Lines of horizontal weakness between layers of limestone are called what?

[x]	Bedding planes
[ ]	Carboniferous fissures
[ ]	Rupture lines
[ ]	Settling levels

Most sedimentary rocks have bedding planes

Rainwater attacks limestone by which process?

[ ]	Abrasion
[x]	Chemical weathering
[ ]	Exfoliation
[ ]	Physical weathering

Limestone dissolves in rainwater because rainwater is naturally slightly acidic

Redeposited limestone rising from a cave floor has what name?

[ ]	Dolomite
[ ]	Kryptonite
[ ]	Stalactite
[x]	Stalagmite

The largest of these can be millions of years old - they grow at a very slow rate

Limestone areas often have which economic activity?

[ ]	Coal mining
[ ]	Fishing
[ ]	Forestry
[x]	Quarrying

The rock has many uses e.g. building, in steelworks, making toothpaste

Which of these National Parks has the most extensive limestone area?

[ ]	Dartmoor
[ ]	Lake District
[x]	Peak District
[ ]	Snowdonia

The Peak District is mainly in Derbyshire but extends into neighbouring counties

Which streams only appear on limestone after heavy rain?

[x]	Intermittent
[ ]	Latent
[ ]	Misfit
[ ]	Sub-continuous

They will only appear when there has been a lot of rain. Some are seasonal and disappear in the summer, like the river Manifold on the border of Derbyshire and Staffordshire

On a diagram, limestone has what type of shading?

[x]	Brick wall
[ ]	Circles
[ ]	Cross hatching
[ ]	Diagonal stripes

Because the rock is full of cracks like some brick walls

What are upright blocks in a limestone pavement called?

[ ]	Brads
[x]	Clints
[ ]	Grints
[ ]	Tors

The gaps between them are called grykes

Why does a gorge floor contain lots of boulders?

[x]	From the collapse of a cavern roof
[ ]	They were carried there by glaciers
[ ]	They were deposited by streams
[ ]	They were thrown by vandals

This can happen when a cave or cavern has formed close to the surface
