Answer 1

Answer:

Iceland sits on crack in the surface of the Earth where two tectonic plates (large blocks that make up the outer most layer of the Earth) are ripping apart from each other. These two blocks are moving apart at around 2 cm per year (approximately the rate that your finger nails grow) and are slowly widening the Atlantic Ocean; increasing the distance from Europe to North America. As the tectonic plates split apart magma (molten rock) wells up from below forming volcanoes, which creates new land in between. This rifting process is happening all the way down the middle of the Atlantic Ocean beneath the sea. But at Iceland we see the process on land because a hot upwelling from deep within the Earth also sits beneath Iceland, pushing it upwards out of the sea and making the area even more volcanically active.When you think of Icelandic volcanoes, the one you will probably remember is the eruption of the volcano with the long, hard to pronounce name that had news readers getting their tongues in a twist: Eyjafjallajökull, which sits under a glacier in southern Iceland. This volcano erupted in 2010 and was all over the news because it produced so much ash that it grounded 100,000 flights and closed European air space. The main reason why this eruption was so ash heavy was due to the interaction of the hot magma erupting under the cold overlying ice. But a couple of years later in 2014 there was another eruption in Iceland, at a volcano called Bárðarbunga. It was the largest eruption in Iceland in over 200 years, and was 10 times bigger than than the eruption of Eyjafjallajökull, but it didn't ground a single flight.
