First 132 words of the document:

Situated in Devon, South-West England.
Founded in 1995 by the National trust.
Largest granite outcrop in the UK.
Formed during Carboniferous period.
Formation of a tor:
The granite, whilst underground in warm and wet climates, is
weathered rapidly.
This depends on how wide the zones are; the wider the zone,
the quicker it is weathered.
During the previous ice advancement and because of erosion
and mass movement, the overlying rocks are swept away
leaving just the granite outcrop.
The broken up granite forms scree, and the wider zones are left
towering over as they weren't weathered as much.
Some of the scree sits on top of the tor because it was eroded
before the rest.

dome about 125 miles long and 50 miles wide.…read more

Rocks underneath London form a basin

Water soaks into exposed chalk either
side of London and percolates through the
rock to form a giant underground reservoir
called an aquifer.
This aquifer has supplied London with
water for hundreds of years.
The water table level is managed
In the 1960s, due to industrial
over-use, the water table dropped 60
However since then it has risen on
average 3 metres a year.…read more
