Seamounts are submarine volcanoes that form on the ocean floor.

They are formed by hotspots (which are hypothesised to be the result of mantle plumes although there is some controversy over this theory in the geophysical community) which cause melting of the crust. These hotspots in the upper mantle are in fixed locations, so as the tectonic plate moves over the hotspot a chain of seamounts forms creating a line in the direction of the plate movement.

What is the The chain of islands formed by the pacific plate moving over a hot spot?

The chain of islands formed by the Pacific Plate moving over a hot spot is known as the Hawaiian Islands. As the Pacific Plate shifts northwestward over a stationary magma plume, volcanic activity creates new islands. Over time, older islands erode and sink, resulting in a linear chain of islands and seamounts. This geological process illustrates the dynamic nature of plate tectonics and volcanic activity in the region.


Where are most seamounts located?

Most seamounts are located in the Pacific Ocean, particularly in regions like the Hawaiian Islands, the western Pacific, and the northwestern Pacific. These areas have extensive volcanic activity and tectonic plate movements that contribute to the formation of seamounts.


What is the plate that contain the most hot spots?

Probably the pacific Plate. The permanent hot spots are revealed by chains of volcanic islands. The chain itself reveals the direction the plate is moving.


Describe the relative motion between the north American plate and the pacific plate?

The Pacific Plate is currently being subducted under the North American Plate. Subduction zones are when one plate is being forced under another at a convergent boundary (where two plates collide). When the Pacific Plate is being subducted under the North American Plate, the crust of the Pacific Plate melts, and creates volcanoes along the edge of the North American Plate. So, the relative motion of the two plates is that they are converging, or moving together.This same process is happening at the South American and Nazca Plates.


What direction the pacific plate is moving?

The Pacific Plate is moving northwest. It is moving at a rate of about 10 cm (4 inches) per year in relation to the North American Plate. This movement creates tectonic activity along the plate boundaries, leading to earthquakes and volcanic eruptions.

Which plate contains the hawaiian island-emperor seamount chain?

The Hawaiian Island-Emperor Seamount Chain is primarily located on the Pacific Plate. This volcanic chain was formed as the Pacific Plate moved over a stationary hotspot in the Earth's mantle, resulting in the creation of the Hawaiian Islands and the seamounts to the northwest. The chain extends from the islands of Hawaii to the northwest, where it transitions into the Emperor Seamounts.

What plate is moving the fastest?

The Pacific and Cocos plate.

What direction does the pacific plate moving?

eastward


Which plate is the North American plate moving towards?

The North American plate is generally moving westward towards the Pacific Plate. This movement is responsible for geological activities such as earthquakes and volcanic eruptions along the Pacific Ring of Fire.


What is the fastest moving tectonic plate?

The Pacific Plate moves faster than any other tectonic plate, averaging about 10 centimeters per year. Its swift motion leads to a range of dynamic geological phenomena, such as frequent earthquakes and volcanic eruptions along its boundaries.


Which way is the pacific plate currently moving?

north west

What tectonic plate is forming the new island of Loihi?

The new island of Loihi is forming on the Pacific Plate. It is a seamount located south of the Big Island of Hawaii, and it is part of the Hawaiian-Emperor seamount chain. The Pacific Plate is moving northwestward over a hotspot, which is causing volcanic activity that is building the island.


How much does the Pacific plate move each year?

The pacific plate is moving in a northwesternly direction


What direction the pacific plate is moving?
