Earth Sciences Geology : Why Are 70 Of The Volcanoes Located Around The Circumference Of The Pacific Ocean
Does it mean that the Earth's core is extremely hot in the Pacific Ocean area? Are the volcanoes extremely active? ~~~ gary ~~~
Best Answer To Earth Sciences Geology Question
Heat from the core escapes towards the surfaces. For reasons that are not well understood, heat sometimes melts rocks, which then rise buoyantly toward the Earth's surface. When the hot rocks -called magma- and included gases break through the crust, an eruption occurs. The build up of ash and lava flows around the vent makes a this case, the Earth's plates in the Pacific Ocean are colliding because of the weak Mantle which make the area have many volcanoes.
All Answers To Earth Sciences Geology Questions
Answer 1Nope, the Earth's core is much further down. All around the edges of the Pacific are a bunch of tectonic plates that collide or slide under or over each other. These tear apart the crust and tend to promote the formation of volcano's.
Answer 2Could it be because the tectonic plates are most active there, allowing for more vents? I'm not certain about this.
Answer 3It's not because of the Earth's core. It's because the pacific is surrounded by the edge of some of the earth's crustal plates. Therefore there's a gap in the earth's crust which magma seeps up through.
Answer 4Most volcanoes are located at convergent plate boundaries, where the Earth's tectonic plates move toward one another.
Answer 5Nope... its just that pacific ocean is at the ring of fire and most of its islands is an island arc which is made by volcanoes... that's why they have a lot of volcanoes there. The earth's core is at the center so the heat distribution is just the same with others. And the magma of the volcanoes is from the mantle not the core. And what happened to the plates is convergent boundary, when two plates (oceanic plates and continental plates or two continental plates or two oceanic plates) collided they can create a volcano or an island arcs. Yes, most of the volcanoes in the Pacific Ocean is a Composite Volcano which is extremely active like Mt. Pinatubo which exploded in 1991 and its ashes almost scattered everywhere in different countries and changes the Climate in the Philippines dor 2 years. :gt; hope this helps
