These are Tors on Dartmoor
The main granite landforms are tors, which can be found on moors such as Dartmoor and Bodmin Moor. Tors are blocks of granite that have weathered slower than the granite around them, because they have less joints and faults. 6
Where you find limestone (yellow) and what it is like underground
Carboniferous limestone produces distinctive karst scenery. These areas are dry on the surface due to the permeability of the rock, but have mainly been shaped by the action of water.

Limestone
What is limestone like? Formed from the remains of organic matter, usually seashells and plants. It was formed under the sea 220280 million years ago. It is a hard, grey sedimentary rock, with a large number of joints (vertical cracks) and bedding planes (horizontal cracks) Carboniferous limestone is an example of a pervious rock, as it allows water to flow through the joints and bedding planes. The main processes which affect it is chemical weathering. Rainwater which is a weak acid dissolves the limestone Two best areas of limestone in Britain are the Yorkshire Dales and the Peak District. 10

Uses of a granite area
Granite areas themselves have limited economic uses. The soil is usually poor and thin, so little farming takes place, probably just some sheep and cattle grazing. Because granite is impermeable, and the soil is poor, areas such as Dartmoor are ideal sites for reservoirs. Quarrying occurs of granite itself, which is used in building (an excellent example being the city of Aberdeen, which is known as "the Granite City"). Granite is also used for things such as hearths, fireplaces, and gravestones. Tourism is increasingly becoming important in granite areas. Many tourists just come to take in the fresh air and beautiful scenery, but the towns and villages of these areas are trying to cash in by opening guesthouses, cafes and other tourist facilities.
How the Tors formed
The granite seen on Dartmoor originated as a granite batholith, under the surface of the earth. A batholith is an area of molten rock that has cooled very slowly within the crust, creating a rock with large crystals. Over time the material above the batholith was weathered and removed by rivers and glaciers. As this material was removed there was a reduction of pressure on the granite as there was less above it. This caused it to crack creating joints and cracks. Where the joints were close together the most rapid weathering occurred, and quickly broke down the rock. However there were also areas where there were very few joints and so slower weathering occurred. The main form of weathering is freeze-thaw. As this process continued over millions of years, the overlying material was totally removed, leaving behind the tors and valleys seen on Dartmoor. 7

Where you find limestone and what it is like underground
The water attacks the many joints and bedding planes in the rock, through the chemical weathering processes. There are a number of distinctive features seen in karst scenery areas, both on and beneath the surface. Limestone pavements are large areas of exposed limestone. When the overlying rock was eroded the pressure release on the limestone below caused it to crack even more. Hence limestone pavements are characterised by large gaps between the rock, called grikes. The remaining blocks of rock are called klints. Limestone cliffs or scars are produced at the edge of the area of limestone. Often near vertical and highly jointed.

Granite
What is granite like? Granite is made up of three minerals: quartz, feldspar and mica. It is a hard, crystalline rock, which is very resistant to erosion. It is an intrusive igneous rock. This means it cooled slowly deep underground. Over time the layers above it have been eroded away, leaving a high, often rounded area. The main processes that affect it are freezethaw and chemical weathering.
Different rocks have different uses and different landscapes
Theyre 3 sources of rock
Sedimentary?
Rock that was once magma Rock that has been heated and/or squashed so much that the chemicals have been change to make totally new substances Rock that has resulted from pieces being removed from other rocks by weathering or erosion, transported and then laid down and gently cemented together Igneous?
