In seafloor spreading molten material rises from the mantle and erupts?

When spreading molten material rises from the mantle in the sea-floor and erupts, it can create sea mounts, which are underwater mountains. If enough material is ejected, the mounts will break through the surface of the water to create islands.


What landforms rise above the ocean floor?

Examples of landforms that rise above the ocean floor include islands, seamounts, and ridges. Islands are areas of land completely surrounded by water, while seamounts are underwater mountains that peak above the ocean floor. Ridges are long, elevated areas that can stretch for thousands of kilometers along the ocean floor.


Sea mounts are deep cuts in the ocean floor?

Sea mounts are underwater mountains that rise from the ocean floor but do not break the surface. They are formed by volcanic activity or tectonic plate movement, and are often rich in marine life due to the upwelling of nutrients they provide. These underwater features can play important roles in ocean ecosystems and biodiversity.


What are the types of telescope mounts?

The two most common types of mount are the alt-azimuth mount, and the equatorial mount, the latter being tricky to set up at first, but much easier to use in the long run. There are other special purpose mounts, too, especially for observatory instruments.


What percentage of all rock outcrops are on the continents?

Almost all. The word-definition answer would be the ratio of land classed as continents to that classed as islands, but geologically, most islands are on their nearest continent anyway. (Look at a map that shows the Continental Shelves). The few exceptions amount to a very tiny fraction of the total area, and these are surface-breaching volcanic sea-mounts rising from mid-ocean ridges and intra-plate vulcanism, like Hawaii and The Canaries.

Are Steep-sided islands are sometimes formed by sea mounts.?

true


Are Sea mounts are Steep-sided islands are sometimes formed by sea mounts?

Yes, seamounts can form steep-sided islands when volcanic activity builds them up above the ocean surface. These underwater mountains, created by volcanic eruptions, may eventually erode or rise above sea level, resulting in steep islands. Over time, the geological processes can shape these islands into prominent landforms.


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


What plates make dome mountains?

dome mounts r not formed directly by any plate boundaries


How many engine cradle mounts does a car have?

Usually four, but sometimes six. Each mount has an upper and lower half, sometimes referred to as clamshells.

could be the motor mounts as to it jerking if its not the tranny..


Exact location of motor mounts?

this is formed by crossing lines of latitude and longitude and creates coordinates for finding absoulte location.


What type of mounts does the company Chief Mounts manufacture?

The company Chief Mounts manufactures a wide number of mounts, such as TV mounts, monitor mounts, tablet mounts, projector mounts and interactive mounts.

How are sea mounts formed?

by Danny yang, sea mounts are made by something like lava pushing up from the surface and soft stuff gets blown away by wind and the bump in the ground is letf there to dry and then get turned into a hard stone

Loose motor mounts.
