Natalie Harvey Helen Dacre Reading Helen Webster David Thomson Mike Cooke Met Office Nathan Huntley Durham Impact on aircraft 2 Volcanic ash is hard and abrasive Volcanic ash can cause engine failure. Where do volcanoes occur—and why?. Divergent [MOR] boundaries . About 75% of erupted lava is found here. Basaltic magma; low viscosity, therefore it flows easily!. Oceanic crust ranges from about 2 km to 10 km thick. Vocabulary. Crater. – bowl-shaped formation at the top of a volcano. Caldera. – large crater formed by the collapse of a volcano during a violent eruption. Active Volcano. – . a volcano that has erupted in the past 10,000 years, may be currently erupting, and is expected to erupt again.. By Robbie Barker, Maximilian Bryson, and Brendan . P. etrili. What is a volcano. A volcano is an opening in the Earth’s surface through which magma rises.. Formation of volcanoes. 1.Most volcanoes occur at colliding boundaries.. By Karanasiou Katerina B1. 07/02/2017. Volcano…. Volcano is open passageway from the interior of the Earth that allows blast rock and gases from the interior to the cortex surface in the form of lava. This activity creates mountains.

We also learned that the crust is broken into many different pieces called Plates.. The plates are constantly moving because of Continental Drift.. Fig. 1.
