Scientists might find Iceland a good place to conduct research on seafloor spreading because it is an islnad full of volcanoes or becuase it lies on mid atlantic and the Atlantic Ocean.
Iceland is a place where, because of large amounts of lava extrusion, the ocean floor is, in effect, above sea level, making it easy to study ocean floor spreading. You can affix strain gauges on many parts of the spreading ridge.
What else can I help you with?
Where on earth would you find seafloor spreading?
You can find the seafloor spreading in the middle of the Atlantic Ocean. It is pushing Europe and Africa away from North and South America. You can go to Iceland and stand on the place where the spreading seafloor comes onto land. There, you can put one foot on Europe and one foot on America. It would be quite a while before your feet became another inch apart.
What forms when continental plates pull apart at divergent boundaries on land?
On land, this forms a rift valley. When the surface is submerged, it is called seafloor spreading.
How did the discovery about seafloor spreading modify the theory of Continental drift?
Seafloor spreading explained WHY and how Continental Drift occurs. How can lands be 'moving' without a catastrophic or even noticeable change--- seafloor spreading accounts for these small changes. It identifies where the actual changes take place (even if we cannot identify the exact spots where spreading occurs). We can better estimate how much the "spreading" equates to observable/measurable changes of continents, specifically how fast (slowly) continents are moving closer or further apart. Seafloor spreading explains other phenomena, too, like the expulsion of methane gas pockets at the ocean floor which are suspected to interfere with flotation of ships and possibly the downing of airplanes that pass over where methane is released when methane gas disrupts the air above the water. Seafloor spreading also gives clues as to how mountains and valleys form underwater and on land.
Explain the relationship between trenches and seafloor spreading?
1. New sea-floor is created by the upwelling of magma at mid-ocean spreading centers; old ocean floor is destroyed by subduction at deep sea trenches. 2. The area is a subduction zone. Magma from underground comes up and destroys that crust. That crust is then recycled and the magma cools and hardens. That creates new land, that creates the trenches. Seafloor spreading is in the ocean and happens with convection currents. That is the relationship between. 3. As new seafloor is formed at mid-ocean ridges, the old seafloor is pushed down into trenches at subduction zones.
What land area of Iceland?
The land area of beautiful iceland is 39.770 sq miles.
How do land structure of Iceland help confirm seafloor spreading?
the Iceland is directly on top of the mid-Atlantic Ocean.Iceland has volcanoes.
How do the land structures of icland help confirm seafloor spreading?
the Iceland is directly on top of the mid-Atlantic Ocean.Iceland has volcanoes.
Seafloor spreading begins when?
Seafloor spreading is triggered by a rift in a continental land mass.
At a divergent boundary land is gained or lost?
At a divergent boundary, land is gained. Ocean ridges are prominent at divergent plate boundaries. Ocean ridges are areas of seafloor spreading. Seafloor spreading occurs as upwelling magma rises to the surface. This upwelling magma hardens and forms new seafloor.
How does the land of ice and confirm seafloor spreading?
The land of ice, particularly in regions like Greenland and Antarctica, provides valuable geological evidence for seafloor spreading through the examination of glacial deposits and ancient rock formations. As tectonic plates move apart at mid-ocean ridges, new crust is formed, which can be observed in the age and composition of rocks on land. The alignment of magnetic minerals in these rocks also reflects the history of seafloor spreading, revealing periodic reversals of Earth's magnetic field. These geological features support the theory that continents drift as new oceanic crust forms beneath the ice.
How is seafloor spreading different continental drift?
seafloor spreading is when molten material rises and cools down and makes new seafloor, continental drift is the theory that the continents were once together and the big land mass is called Pangea.this is fake story no one believe it i got wrong
Which geological processes were involved in the formation of Iceland?
Iceland was formed by volcanic activity and the movement of tectonic plates. The island sits on the Mid-Atlantic Ridge, where the North American and Eurasian plates are pulling apart, causing magma to rise to the surface and create new land. This process, known as seafloor spreading, has led to the formation of Iceland over millions of years.

How does seafloor spreading affect us?
seafloor spreading affects us with help from continental drift. seafloor spreading creates new seafloors, but moves the continents a few centimeters apart from each other every year. in many years, pangaea will become aeagnap, because the continents will become one big land again, but backwards, and will damage the faults and the only land we have severely.

What occurs at divergent boundaries and creates new seafloor?
At divergent plate boundaries the spreading of the tectonic plates results in the reduced pressure of the underlying magma. As the spreading continues, lava fills in the area of spreading and cools, becoming the newest addition to the seafloor. This process occurs at a steady rate ranging from a few centimeters to several centimeters of new sea floor each year. However, at a different location opposite the newly formed seafloor are convergent plate boundaries where land and seafloor is destroyed to make room for new seafloor.
