6. Iceland is located on the Mid-Atlantic
Ridge.
The North-American and Eurasian
plates move apart- called constructive
plates.
This causes magma to rise to the
surface and form volcanoes.
The latest eruption occurred under a
glacier.
The water cooled the lava quickly
resulting in glass particles entering the
plume.

8. Primary Impacts- occur as a direct result of the event.
Secondary Impacts- occur because of a change to the
environment as a result of the event.

A A common and devastating result of some explosive volcanic eruptions.
The flows are fast-moving currents of hot gas and rock, which travel away
from the volcano at speeds generally as great as 700 km/hr (450 mi/h). The
gas can reach temperatures of about 1,000 C.

3
A mass of molten rock larger than 6.5 cm in diameter, formed when a volcano erupts
during a lava eruption. They cool into solid fragments before they reach the ground.
Lava bombs can be thrown many kilometres from an erupting vent, and often acquire
aerodynamic shapes during their flight.

A lahar is a type of mass movement composed of ash and water that flows down
from a volcano, typically along a river valley. It may occur after rainfall or if volcano
with a lake or glacier erupts.

Volcanic ash consists of small bits of pulverized rock and glass created by volcanic
eruptions, less than 2 mm in diameter. Cause massive disruption as can damage
airplane engines, therefore causing global transport disruption. Ash can build up
on house roofs causing them to collapse.

Volcanic gases are given off from active volcanoes
throughout the years as well as during an eruption. It often
consists of a mix of carbon dioxide and sulphur dioxide
amongst others. A significant eruption into the atmosphere
can cause a volcanic winter.
