What are the products of mechanically weathered granite?
Regional SpecificsHydrolysis is the chemical weathering of minerals by a mildly acidic water that forms when rains dissolves trace gases in the atmosphere. The reaction of feldspar minerals in granite with rainwater produces kaolinite, white clay known as “China clay” used in the production of porcelain, paper and glass.

Which supervolcano is most likely to erupt?
Regional SpecificsWhat supervolcano is most likely to erupt next? The researchers say that an extra four cubic kilometres of magma builds up in Toba every thousand years. This means that next equivalent super-eruption would occur in 600,000 years – though smaller ones could happen in the meantime. What is the most active supervolcano? Taupo erupted 22,600
