Volcanoes

1 November, 2020

Lava is a red hot liquid when it pours out of a vent. But it becomes dark red, black or grey as it cools and solidifies. Volcanoes are very destructive but on the other hand it could be constructive as scientists suggest that 80 percent of the Earth’s surface is originally made up of the lava which has already solidified.

There are more than 500 active volcanoes in the world, which are currently erupting or showing signs of it. Most of the world’s active volcanoes are along or near the margins of continents. More than half of these volcanoes circle the Pacific ocean in what is called, “The Ring of Fire”

This “Ring of Fire” is an arc stretching from New Zealand along the eastern edge of Asia, North across the Aleutian islands of Alaska and South along the coast of North and South America. It is on the border of the Pacific Plate and other tectonic plates.
