How did the volcanoes of Indonesia form?
Abstract. Geography of Indonesia is dominated by about 150 volcanoes of all types and dimensions that were formed due to subduction processes occurring along the collision zone separating the Eurasian and the Indo-Australian tectonic plates. … 74,000 BC, which caused a long 6-year volcanic winter.
How the volcanoes were formed?
A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth’s surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Hot ash and gases are thrown into the air.
How are volcanoes formed short answer?
Volcanoes are formed when magma from within the Earth’s upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.
Why does Indonesia have so many volcanoes?
Indonesia is the country that contains the most active volcanoes of all countries in the world. The Eurasian Plate, Pacific Plate and Indo-Australian Plate are three active tectonic plates that cause the subduction zones that form these volcanoes.
Where are volcanoes found?
Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”
