Best Answer

Earthquake occur because tectonic plates are grinding against each other, causing movement along faults which in turn causes earthquakes. Volcanic activity occurs at subduction zones because the subducting plate introduces water into the mantle, which allows mantle rock to melt. Volcanoes form at divergent boundaries because the thinned crust reduces pressure on the upper mantle, allowing rock to melt.

Do most earthquakes and volcanoes occur within plates or along the boundaries of plates?

Earthquakes and volcanoes occur mostly near the convergent plate boundary.


What might occur as a result of plate boundaries?

volcanoes earthquakes and a fault


What plates do earthquakes and volcanoes usually occur at?

The edge of the Pacific plate is known as the "Ring of Fire" because it has very high concentrations of earthquakes and volcanoes. However, most plate boundaries are capable of producing earthquakes and volcanoes at least occasionally.


Where are earthquakes or volcanoes likely to occur?

The answer is that earthquakes and volcanoes are most frequent along Tectonic plate boundaries, these are the natural pieces that the continents and oceans are on.


Do volcanic eruptions and earthquakes occur ONLY at the boundaries?

No. Volcanoes can be found at hot spots away from plate boundaries. These volcanoes can produce earthquakes. Earthquakes can also occur at areas of ancient geologic activty such as failed rifts and can occur as a result fo glacier retreating.


Where are the majority of earthquakes and volcanoes in relation to the plate boundaries?

Most earthquakes occur on plate boundaries such as Japan and Chile and most volcanoes occur in diverging plate boundaries like Dallol and Iceland and the Pacific Ring of Fire like Ecuador and Indonesia

Why do earthquakes and volcanoes usually happen at plate boundaries?

Earthquakes occur when two plates that were pushing against each other slip apart and all the pressure gets released causing the earthquake. And idk about volcanoes
