What is the hot spot for plate movement?

What is the hot spot for plate movement?

A hotspot is a large plume of hot mantle material rising from deep within the Earth. A line of volcanoes develops as a plate moves over a hotspot, much as a line of melted wax forms as a sheet of waxed paper is moved slowly over a burning candle.

What is a result of a hot spot?

In geology, a hotspot is an area of the Earth’s mantle from which hot plumes rise upward, forming volcanoes on the overlying crust.

Which of the following forms as a result of a hot spot?

Because the location of hot spots remains relatively fixed in the mantle for extended periods of time, the product of the hot spot volcanism is a linear track of volcanic activity. Thus, a chain of seamounts (or islands) is formed as the plate moves over the hot spot.

What is the outcome of hotspots?

A hotspot’s position on the Earth’s surface is independent of tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them.

How do hot spots prove that the continents move?

The large amounts of molten rock spewed forth cools forming new landmasses. The Earth’s crust is made up of giant tectonic plates which are constantly moving. As a tectonic plate moves over a volcanic hot spot, the intermittent eruptions create a chain of new lands.

What are hot spots and what do they tell us about plate movement and the formation of islands?

Hotspots are plumes of magma that originate in the earth’s mantle and move outward through the crust. As a crustal tectonic plates move over hot spots mantle material upwells and erupts on the surface of the plate to form a volcano, seamount or volcanic island.

What is a hot spot example?

In the interior of some tectonic plates, magma has been erupting from a relatively fixed spot below the plate for millions of years. As the plate continuously moves across that spot, a trail of progressively older volcanic deposits is left at the surface. The Hawaiian Islands are a good example of this.

Why is it called hotspot?

The company was sold to Deutsche Telecom in 2001, who then converted the name of the firm into T-Mobile Hotspot. It was then that the term hotspot entered the popular vernacular as a reference to a location where a publicly accessible wireless LAN is available.

Do hotspots occur at plate boundaries?

Hot spot volcanoes occur far from plate boundaries. Because the hot spot is caused by mantle plumes that exist below the tectonic plates, as the plates move, the hot spot does not, and may create a chain of volcanoes on the Earth’s surface.

What happens when a tectonic plate moves over a hotspot quizlet?

Tectonic plates slowly move over a hot spot. Volcanoes form on the lithosphere above the hot spot as hot magma melts through the lithosphere and erupts. The magma cools and hardens, forming a volcano. When the tectonic plate moves off the hot spot, the volcano becomes dormant.

Why are hotspots important to plate tectonics?

Hotspots are related to plate tectonics in that they can provide evidence to support the theory of plate tectonics in the form of long chains of volcanoes. For the most part, hotspots are stationary in the mantle, while tectonic plates keep moving.

Is Iceland over a hot spot?

The Iceland hotspot is a hotspot which is partly responsible for the high volcanic activity which has formed the Iceland Plateau and the island of Iceland.

How are hot spot volcanoes formed?

Occasionally volcanoes can form right in the middle of a plate. These so-called “hotspot” volcanoes are created when a narrow stream of hot mantle rises up from deep inside the earth and melts a hole in the plate so that the magma can ooze upward.

What is hot spot and divergent plate boundary?

Hot-spots occur in the middle of plates, often thousands of kilometres away from the boundaries of the plates. Divergent boundaries are not being pushed apart by rising magma. On the contrary, the plates are moving apart because they are pulled down at subduction zones and this creates a hole which magma rises to fill.

How are hot spot volcanoes formed?

These so-called “hotspot” volcanoes are created when a narrow stream of hot mantle rises up from deep inside the earth and melts a hole in the plate so that the magma can ooze upward. The Hawaiian islands, for example, are a result of hotspot volcano formations near the center of the giant Pacific plate.
