Multiple choice general knowledge history

The 2010 volcanic activity of Eyjafjallajökull was very disruptive to air traffic because

  1. The volcano is directly under the jet stream

  2. The eruption took place under 200m of glacial ice which increased the explosive power

  3. The erupting lava cooled very rapidly which created a cloud of highly abrasive, glass-rich ash

  4. The volcano's explosive power was sufficient to inject ash directly into the Jet Stream

A,B,C,D Correct answer
Explanation

The 2010 Eyjafjallajökull eruption was exceptionally disruptive due to a perfect storm of geographical and geological factors. The volcano's position directly under the jet stream (A) allowed ash to be carried across Europe quickly. The eruption occurred beneath 200m of glacial ice (B), causing rapid magma cooling that increased explosive power and created highly abrasive, glass-rich ash particles (C). This combination injected fine ash directly into the jet stream (D), which then dispersed across major air traffic routes, forcing widespread flight cancellations.
