Most volcanoes form at either convergent or divergent plate boundaries. Volcanoes at convergent plate boundaries form when one plate slides under another, taking seawater with it. This causes the rock in the mantle to melt as the melting point drops. This new magma can rise to form volcanoes.
At divergent plate boundaries the crust is thing, which lowers pressure on the mantle, causing some material to melt.
What else can I help you with?
Are volcanoes located in the center plates?
Not usually. Most volcanoes are located near plate boundaries, but some volcanoes at hot spots do form in the middle of plates. A few include the volcanoes of Hawaii, the volcano at Yellowstone, and the Volcanoes of the Canary Islands.
Where are the 1 million volcanoes located on earth?
The number of volcanoes on Earth is nowhere near 1 million. There are about 1,500 active volcanoes on Earth, most of them near the boundaries of tectonic plates. About half of them are scattered along the rim of the Pacific Ocean.
Are most volcanoes located near the edge or near the center of the continents?
they are located on the edge of plates because that's where the land grinds and shifts the most notable of the plate boundaries is the boundary around the pacific plate known as the ring of fire
What fault line is San Simeon on?
San Simeon is located near the San Andreas Fault, one of the most well-known and active faults in California. This fault is responsible for the movement of tectonic plates in the region, leading to earthquakes.
Do most volcanoes form near colliding plate boundaries?
Most volcanoes do form near colliding plate boundaries where subduction occurs, such as the Ring of Fire in the Pacific Ocean. However, volcanoes can also form in other geologic settings, such as hotspots and rift zones.
Are most volcanoes near edges?
yeas due to the fault line near the edge of the continent
Are most earthquakes located near the edges or near the center of the continents?
Most earthquakes and volcanoes are on the Pacific rim of fire.
Why are there more volcanoes in southern California?
There is a fault line near San Fransisco, therefore causing volcanoes. Magma from inside the Earth pushes up along the fault zone, causing volcanoes.
Are volcanoes located in the center plates?
Not usually. Most volcanoes are located near plate boundaries, but some volcanoes at hot spots do form in the middle of plates. A few include the volcanoes of Hawaii, the volcano at Yellowstone, and the Volcanoes of the Canary Islands.
Near what geologic structures are most of Earth's explosive volcanoes located?
Most explosive volcanism is located at oceanic to continental subduction zones.
What usually occurs near a fault line in the Earth's crust?
Earthquakes, and volcanoes form.
Is Brazil near any earthquake fault lines or is there any active or dormat volcanoes?
no
Where are the 1 million volcanoes located on earth?
The number of volcanoes on Earth is nowhere near 1 million. There are about 1,500 active volcanoes on Earth, most of them near the boundaries of tectonic plates. About half of them are scattered along the rim of the Pacific Ocean.
What are the earthquake prone areas of the world?
The earthquake prone areas are those on or near fault lines or subduction zones, and those near active volcanoes. Most of the rim of the Pacific Ocean is one such area.
Where are earthquakes primarily located?
Near fault lines.
What is the patteren between Ayelu and Likaiu volcanoes?
both volcanoes are located near the African plate boundary
Are most volcanoes located near the edge or near the center of the continents?
