Volcanoes are not randomly distributed over the Earth's surface. Most are concentrated on the edges of continents, along island chains, or beneath the sea forming long mountain ranges. More than half of the world's active volcanoes above sea level encircle the Pacific Ocean to form the circum-Pacific "Ring of Fire." In the past 25 years, scientists have developed a theory -- called plate tectonics -- that explains the locations of volcanoes and their relationship to other large-scale geologic features...

Why do volcanoes erupt by boundaries the most?
Volcanoes often erupt at boundaries because this is where tectonic plates interact, causing intense heat and pressure to build up beneath the Earth's surface. This leads to the melting of rock and the formation of magma, which can eventually erupt as lava and volcanic ash through the volcano's vent.
How do volcanoes hold their blast?
Volcanoes don't erupt for even 100s of years. They hold the magma just still until some tectonic plates activate the eruption.
Where and why do volcanoes occur?
Volcanoes occur when magma makes it way to the surface. The volcano begins as a lava flow but as it continues to erupt the volcano gets bigger. The volcano eruptions are determined by the pressure and density of the magma chamber.
Are volcanoes in the center of tectonic plates?
no
How can volcanoes errupt under water?
Volcanoes can erupt underwater when magma rises to the surface through a weak spot in the Earth's crust on the ocean floor, known as a mid-ocean ridge or a hotspot. When the magma reaches the cold ocean water, it can cause the water to heat up rapidly, leading to explosive eruptions and the formation of underwater volcanoes.

How does tsunami erupt?
well there are tectonic plates at the end of the sea and then one of those tectonic plates go up and a tsunami will erupt?

Can volcanoes be cause by spreading tectonic plates?
no
When did a shield volcano erupt?
because movement of tectonic plates
What occurs at the edge of tectonic plates?
Scientists observed that volcanoes and earthquakes occur at the edge of tectonic plates.
Name two countries that have volcanoes that erupt occasionally?
It is not uncommon for volcanoes to erupt every year, someplace in the world. Two countries that have volcanoes that erupt from time to time are the United States and the Philippines. Other countries include El Salvador, Iceland, and Africa.
Why are no volcanoes found in certain parts of world?
Volcanoes are only found on the edge of tectonic plates & they can also be found on cracks in the tectonic plates which is un-common
Where do volcanoes mostly form?
Volcanoes usually form where tectonic plates meet.
