What else can I help you with?
If an ocean trench is located west of a line of volcanic islands it would then be assumed that?
If an ocean trench is located west of volcanic islands, you can assume that there is a continental shelf nearby. You can also assume that the trench is at least 7000Êm deep.
What island arc?
The definition of the word island arc is " a curved chain of volcanic islands located at a tectonic plate margin, typically with a deep ocean trench on the convex side."
What is the chain of volcanic islands that form parallel to a deep ocean trench?
The chain of volcanic islands that form parallel to a deep ocean trench is known as an island arc. These arcs are created by the subduction of one tectonic plate beneath another, leading to melting of the mantle and formation of magma that rises to the surface. Common examples include the Aleutian Islands in Alaska and the Japanese archipelago. Island arcs are characterized by their volcanic activity and often have a curved shape.
What is the definition of volcanic islands?
A Volcanic Island is an island that was made from volcanoes erupting from the ocean floor.
The Mariana Trench where is it?
The Mariana Trench is located south of Japan and east of China, in the northern Pacific Ocean, near the island of Guam.
What does an ocean-ocean convergence give rise to?
volcanic island arcs
What is the relationship between seamount and volcanic island?
A seamount is an underwater mountain formed by volcanic activity, while a volcanic island is a landmass that rises above the ocean's surface due to volcanic eruptions. Seamounts can eventually grow to become volcanic islands if the volcanic activity continues and brings the seamount above the water level.
What is a island arcs?
it is a string of islands formed above a deep ocean trench
What is formed when two plates collide into each other?
It depends on the type of crust involved. If both plates carry oceanic crust, an ocean trench is formed along with a volcanic island are on the overriding plate. If one plate carries oceanic crust and the other continental, you will get an ocean trench, a continental volcanic arc, and a mountain range. If both plates carry continental crust, then a mountain range is formed.
What type of island is Hawaii?
Hawaii is a volcanic island, formed by volcanic activity millions of years ago. It is part of a volcanic island chain in the Pacific Ocean.
What happens if an oceanic to oceanic happens?
When an oceanic to oceanic happens, two oceanic plates converge and one of the plates subducts into a trench. The subducted plate sinks down into the mantle and begins to melt. Molten rock from the plate rises toward the surface and forms a chain of volcanic islands, also called a volcanic island arc, behind the trench in the ocean.
How do sea mounts become volcanic islands?
First of all there are different kinds of sea mounts, in reference to your question it would have to be a volcanic sea mount to begin with. It would become a volcanic island by continuing to erupt until it broke the surface of the ocean. Some excellent examples of volcanic sea mounts that became volcanic islands are the Hawaiian Islands
