- 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. 6 people found this useful.

- Iceland is the largest island on the ridge because of the additional volcanism caused by the hot spot beneath the country, which moves slowly towards the northwest. The tectonic plates move towards east and west, and both the North American and Eurasian systems move to the northwest across the hot spot.

Divergent Boundary Iceland's divergent boundary and hot spot. Iceland sits on a divergent boundary between the North American Plate and the Eurasian Plate that has formed the Atlantic Ocean. The island also sits over a hot spot. The frequent volcanic eruptions are a result of hot spot activity and separating plates.

Evidence for Sea-Floor Spreading Evidence From Magnetic Stripes. When scientists studied patterns in the rocks of the ocean floor, they found more support for sea-floor spreading. You read earlier that Earth behaves like a giant magnet, with a north pole and a south pole. Surprisingly, Earth’s magnetic poles have reversed themselves many times during Earth’s history.

Iceland is one of the most tectonically active countries on the world. This is a constructive plate boundary. Aerial view of the area around Thingvellir, Iceland, showing a fissure zone (in shadow) that is an on-land exposure of the Mid-Atlantic Ridge. Right of the fissure, the North American Plate is pulling westward away from the Eurasian Plate (left of fissure). This photograph encompasses the historical tourist area of Thingvellir, the site of Iceland's first parliament, called the Althing, founded around the year A.D. 930.

What Type of Plate Boundary Is Iceland? A: Iceland is on a type of tectonic plate boundary called a divergent boundary. The divergent boundary, called the Mid-Atlantic Ridge, that runs through the center of Iceland occurs because two plates, the North American Plate and the Eurasian Plate, are pulling away from each other.

seafloor spreading Role of the Spreading Center. In 1962 Hess proposed that the seafloor was created at mid-ocean ridges, spreading in both directions from the ridge system. At the spreading center, liquid rock called basaltic magma rises from the earth's mantle as it upwells beneath the spreading axis. When the magma hardens, it forms new oceanic crust that becomes welded to the original crust.

The Iceland hotspot and mighty geological phenomena Iceland sits spanning the Mid-Atlantic Ridge tectonic plate boundary which separates the Eurasian and the North American plates. The ridge, an underwater mountain chain, extends about 16,000 km along the north-south axis of the Atlantic Ocean.celand formed by the coincidence of the spreading boundary of the North American and Eurasian plates and a hotspot or mantle plume – an upsurge of abnormally hot rock in the Earth´s mantle.

Seafloor Spreading 1 Seafloor spreading is one of the two major processes of plate tectonics, the other being subduction. 2  Seafloor spreading is the continuous process of forming new igneous rock at midocean ridges by injection of magma that forms new seafloor.

- Rewrite each statement correctly on the lines provided. 1. During the 1940s and 1950s, scientists began using radar on moving ships to map large areas. of the ocean floor in detail. 2. The youngest rocks are found far from the mid-ocean ridges. 3. The scientist Henry Hess invented echo-sounding devices for mapping the ocean floor. 4. As the seafloor spreads apart, hot saltwater moves upward and flows from the cracks. 5. As the new seafloor moves away from the ridge and becomes hotter, it moves upward and. forms still higher ridges. 6.

How did Glomar Challenger help support seafloor spreading? This Site Might Help You. RE: How did Glomar Challenger help support seafloor spreading? Explain how research from the Glomar Challenger helped scientists support the theory of seafloor spreading. Glomar Challenger. Challenger showed that the sea floor in the atlantic was younger then than the crust in Soputh America and Africa, proving seafloor spreadingand continental drift. Sage, I think you're thinking of the Glomar Explorer, not the Challenger.

- B. rocks formed at spreading ridges preserve paleomagnetic signals that repeatedly reverse through time. C. the paleomagnetic pattern on one side of a ridge is very different to that on the other side of the ridge. D. lavas erupting at mid-ocean ridges today would preserve a positive polarity in the magnetic signal. E. the paleomagnetic stripes in the ocean floor rocks run parallel to the spreading ridge. 4.

Volcanoes Iceland's volcanoes are found along this volcanic ridge. A number of volcanoes also occur along the Rift Valley of eastern Africa, another region where crustal plates are spreading apart. While most volcanoes form where crustal plates are colliding or spreading apart, some are located in the middle of plates.celand's volcanoes are found along this volcanic ridge.

- Finally, Antarctica is a great place to study geology. The geology of Antarctica includes the rocks, ice, glaciers, and the land itself (way down below the ice). Studying geology can help scientists have a better idea of things like earthquakes, volcanic eruptions, glacier movement, and different types of rocks.

Timeline of United States discoveries Oh, and at the opposite end, oceanic crust is being swallowed up by the mantle, all part of one big conveyor belt. OR, in simple terms: Seafloor spreading occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away. -MitchellsLoverJK

Ocean floor mapping This distortion was recognized by Icelandic mariners as early as the late 18th century.

- The result of the addition of new sea floor rock is that the Atlantic Ocean between these sets of continents is widening. North and South America move farther away from Eurasia and Africa each year. The youngest sea floor rocks are found in the middle of the ocean because that is where new sea floor is added.ackground. Sea floor spreading is one component of the theory of plate tectonics. According to this concept, at ridges in many of the world's oceans (mid-ocean ridges), new crustal rock is added to the edges of plates on either side of the mid-ocean ridge.
