As the old crust enters the mantle it brings volatiles such as water with it. This lowers the melting point of the rock around it.

This melted material rises to the earths surface under pressure along with gases and may erupt in a volcano.

Why in some areas volcanoes occur while in other areas they don't have?

Many of the world's volcanoes occur along the edges of boundaries of the plates. Plate boundaries are among the most geologically active places on earth. Here, new rock is being both created and destroyed, so this is where most of the world's volcanic eruptions and earthquakes occur.


Do volcanoes occur in oceans and earthquakes occur on land?

Earthquakes and volcanoes both occur in land and ocean. =)


Where do most of earth's earthquakes volcanoes and mountain building occur geologically?

Most earthquakes, volcanoes, and mountain building occur along tectonic plate boundaries. This is because the movement of these plates creates stress and pressure that can lead to these geological events. The Ring of Fire, a horseshoe-shaped area around the Pacific Ocean, is the most active region for these geological activities.


Which water body is surrounded by a geologically active ring of fire?

The Pacific Ocean. The Ring of Fire is a group of volcanoes. The pacific tectonic plate.


What are the belts called that most earthquakes and volcanoes occur on?

Earthquakes and volcanoes often occur along the boundaries of tectonic plates. These boundaries are known as plate boundaries or fault lines. The most active areas for earthquakes and volcanoes are the Ring of Fire around the Pacific Plate and the Mid-Atlantic Ridge where new oceanic crust is formed.


Does earth's moon have active volcanoes?

Seismic events on the moon are naturally called moonquakes, not earthquakes. They occur, but are less common and less powerful than those on Earth. The moon has no volcanoes since the magma that was under its surface long ago solidified.


Volcanoes and earthquakes are likely to occur?

Yes, they are likely to occur.


Do earthquakes occur near island arcs?

Yes, earthquakes frequently occur near island arcs as they are geologically active regions where tectonic plates are colliding or subducting. Subduction zones along these island arcs can generate powerful earthquakes due to the intense geological activity.


Earthquakes and occur at plate boundaries?

Volcanoes


Why do earthquakes occur at volcanoes?

To release pressure.


What natural occurrences can cause problems for Japan?

Because, over 1000 earthquakes may occur within a year, over 160 volcanoes are still active, tidal waves can occur after earthquakes, and then typhoons are a possibility on the islands.


Why is it unlikely for Northern Ireland not to have a major earthquake?

It is just Ireland's location. As there are no major faults near Ireland, volcanic and seismic activity is low. There are no active volcanoes in Ireland but sometimes very small earthquakes do occur in Ireland, or off its coasts.It is just Ireland's location.
