Geology of the Malvern Hills
At over 600 million years old, the Malvern Hills are some of the oldest rocks in England. The rocks started life as ancient volcanoes erupting under an ocean. The volcanic islands became buried under new layers of sea floor. The Malverns remained covered and eventually resurfaced when the rocks above became worn away. The minerals found in the rocks were formed under intense heat and pessure, which has made them so hard that they do not dissolve in water. The Malvern Hills therefore now provide pure spring water.First broadcast in The Essential Guide to Rocks on BBC4 in November 1998.
This clip could be used in a module on geological processes. Using this clip should illustrate to students how igneous, sedimentary and metamorphic rocks were formed. The clip could also be used to look at water resources.
