Where does hydration melting occur?
Along subduction zones.
Why do so many of earths volcanoes occur along plate boundries?
Volcanoes occur near plate boudaries because volcanoes need water to erupt.
Where do most of the worlds valcanoes lie?
Most volcanic eruptions occur in subduction zones, areas where crust is being drawn under the edge of a less dense plate, as in the Ring of Fire, a subduction zone around the Pacific Rim.
Do volcanoes occur at hot spots?
No. Hot spots and subduction zones are two separate geogolgic settings in which volcanoes can form. Some hot spots may develop as a result of activity in a subduction zone, and continue activity after subduction has ended or move away.
Where do you find volcanoes other than Hawaii?
Volcanoes tend to form at convergent subduction boundaries and divergent plate boundaries. One good example would be the broad ring of volcanoes that have formed around the boundary of the Pacific plate. This is why this region is known as the ring of fire. There is also a very long chain of undersea volcanoes that occur at the mid ocean ridges. In some places these have formed islands such as Iceland. Where subduction occurs (along the west coast of South America, and the west coast of the USA for example) volcanoes form, e.g. Subduction zones also form volcanic island arcs such as the Aleutian island chain in Alaska.
Do Hotspot volcanoes occur along subduction zones.?
No, hotspot volcanoes do not occur along subduction zones. They occur when plates pass over mantle hot spots.
Where does hydration melting occur?
Along subduction zones.
Why are there many volcanoes?
Every time two of earth's tectonic plates meet you are apt to get volcanoes as a result of subduction. They also occur along plate spreading-rifts such as the Mid-Atlantic Rift and the Great Rift Valley in Africa.
Where do earthquakes volcanoes and mountains occur along?
Along the tectonic plate boundaries.
What can occur at places where one plate is pushed below another plate?
It is called subduction. Usually it will form coastal volcanoes.
Do volcanoes occur randomly over Earth's surface?
Volcanoes do not occur randomly over Earth's surface. They occur along the located mark of plate boundaries.
Why do so many of earths volcanoes occur along plate boundries?
Volcanoes occur near plate boudaries because volcanoes need water to erupt.
Where do most of the worlds valcanoes lie?
Most volcanic eruptions occur in subduction zones, areas where crust is being drawn under the edge of a less dense plate, as in the Ring of Fire, a subduction zone around the Pacific Rim.
Where do earthquakes and volcanoes commonly occur?
Along fault lines
Do volcanoes occur where two tectonic plates moves apart and magma rises up to create new crust?
No. Generally volcanoes occur at plate boundaries called subduction boundaries. At a subduction boundary one tectonic plate rides over another and the lower plate is forced down and magma is forced up
Do volcanoes occur at hot spots?
No. Hot spots and subduction zones are two separate geogolgic settings in which volcanoes can form. Some hot spots may develop as a result of activity in a subduction zone, and continue activity after subduction has ended or move away.
