EESA06H3 Lecture Notes - Lecture 4: North American Plate, Eurasian Plate, Plate Tectonics
Document Summary
Iceland is on top of where the eurasians tectonic plate meets the north american plate. Volcano erupted causing cancellations in flights around the world. Floor is always spreading along the mid-ocean ridge. The ridge is only above water in iceland. Pressure of eruption lifts glacier and cause debris to move into the valley. Countryside covered with ash (20cm in last eruption) Caused a mini ice age in the uk at the end of the 18th century. When icelandic volcanoes they erupt it melts ice(causes flash flooding). Houses in iceland are heated by hot water springs. When lakey erupted it destroyed iceland"s southern shore. Plates are built by layers of lava over each other. The royal mile steep is because it was built on a glacial ridge. Basalt (organ pipes) came from rapid cooling of lava. Castle built on the plug of an old volcano. The world was born from heat and older than scholars said it was.
