Question

The map shows 95 volcanoes. Count find what percentage of
them are found in a) the mid-Atlantic Ridge and b) the Pacific
Ring of Fire. Give separate explanations why so many volcanoes
are found in each location.

Answer 1

Answer:

a)Volcanoes. Iceland sits astride the middle of the Mid-Atlantic Ridge, which is an integral part of the global mid-oceanic ridge system. This ridge is a 40.000 km crack in the ocean floor caused by the separation of the North American and Eurasian tectonic plates. ... Volcanic eruptions and earthquakes follow each other.

b)The abundance of volcanoes and earthquakes along the Ring of Fire is caused by the amount of movement of tectonic plates in the area. Along much of the Ring of Fire, plates overlap at convergent boundaries called subduction zones. That is, the plate that is underneath is pushed down, or subducted, by the plate above.
