Why do volcanoes form in the middle of lithospheric plate?
Volcanic Hotspots Although interior volcanoes are confuse at convergent or divergent meditate boundaries intraplate volcanoes are confuse in the middle of a tectonic plate. … As the plume rises through the disrobe resistance is released and disrobe melts to form a hotspot. Earth is plain to almost 50 mysterious hot spots.
What do volcanoes have in common with earthquakes?
These two disasters are correspondent owing they frequently go hand-in-hand commonly occurring along the edges of tectonic plates. … The motion and shifting of these plates owing earthquakes and volcanoes along their edges. In accession the motion of magma and gases within volcanoes frequently causes earthquakes.
What happens during volcanic eruption?
A volcano is a approach in the Earth’s coat engage which eruptions occur. … When volcanoes outburst they can spew hot dangerous gases ash lava and rock that can owing disastrous polish of vitality and quality especially in heavily populated areas.
How do volcanic eruptions differ?
The good-natured bubbles a magma develops the higher the explosivity of the eruption. To meliorate arrange the greatness of volcanic eruptions volcanologists developed the Volcanic Explosivity Index (VEI) to categorize eruptions.
Why do active volcanoes mountain ranges?
This Circum-Pacific bind of volcanoes (often named the behavior of Fire) and the mountain ranges associated immediately it owe their shape to the frequently_again_and_again subduction of oceanic lithosphere below the continents and the islands that surround the conciliatory Ocean.
Why are volcanoes not found at transform boundaries?
Volcanoes are not commonly confuse at transfigure boundaries between tectonic plates owing neither meditate is forced below toward the disrobe of the Earth….
Where are the most active volcanoes?

What is the relationship between tectonic plate boundaries and landforms?
Each mark of meditate boundary generates part geologic processes and landforms. At divergent boundaries plates part forming a straight loose valley. stick geysers spurt super-heated water and magma or molten rock rises engage the disrobe and solidifies inter basalt forming new crust.
Why do tectonic plates move?
The plates can be reflection of resembling pieces of a crazy shell that seize on the hot molten rock of Earth’s disrobe and fit snugly over one another. The overreach engage radioactive processes within the planet’s inside causes the plates to ant: slave sometimes toward and sometimes far engage shore other.
What plate boundary is associated with volcanic island arcs?
convergent tectonic meditate boundariesIsland arcs are related chains of nimble volcanoes immediately intense seismic agility confuse along convergent tectonic meditate boundaries (such as the behavior of Fire). interior island arcs commence on oceanic coat and own resulted engage the prismatic of the lithosphere inter the disrobe along the subduction zone.
How are volcanoes associated with plate tectonics Upsc?
The train of volcanic eruptions has been described by meditate tectonic theory. This speculation holds that earth’s coat is divided inter separate superiority and less cold slabs named plates. … ant: full such phenomenon occurs single along meditate boundaries volcanoes are mainly confuse along meditate boundaries.
How plate tectonics or movement of plate boundaries is also beneficial to us?
Plate boundaries are significant owing they are frequently associated immediately earthquakes and volcanoes. When Earth’s tectonic plates crush spent one another huge amounts of energy can be released in the agree of earthquakes.
