What surface feature is created when a plate move over a hot spot?
These hot spots are able to independently melt the tectonic plate above them, creating magma that erupts onto the top of the plate. In hot spots beneath the ocean, the tectonic activity creates a volcanic mound. Over millions of years, volcanic mounds can grow until they reach sea level and create a volcanic island.
Which location exemplifies a plate hot spot?
Hawaii is an oceanic hot spot in the middle of the Pacific plate. These each display the characteristic patterns for the plate boundary types and features.
What features at the surface provide evidence of plumes?
What features at the surface provide evidence of plumes? Hot spots provide evidence of plumes. How do plates move at divergent plate boundaries? Plates move apart at divergent plate boundaries.
Which landforms are most likely associated with these hot spots?
Which landforms are most likely associated with these hot spots? evidence of sea floor spreading. Most volcanoes develop due to interactions between two tectonic plates.
Where are some hotspots located?
Major hot spots include the Iceland hot spot, under the island of Iceland in the North Atlantic; the Réunion hot spot, under the island of Réunion in the Indian Ocean; and the Afar hot spot, located under northeastern Ethiopia. Volcanic activity at hot spots can create submarine mountains known as seamounts.
Which formation is a result of a hot spot?
Hotspots occur when one of the Earth's plates moves over an unusually hot part of the Earth's mantle. These hot areas are usually relatively stationary and result in large amounts of magma rising up, piercing a hole in the plate to form a volcano. As the plates move, a series of volcanoes can form.
Where does it appear that the hot spot originated?
The origins of the concept of hotspots lie in the work of J. Tuzo Wilson, who postulated in 1963 that the formation of the Hawaiian Islands resulted from the slow movement of a tectonic plate across a hot region beneath the surface.
Where are volcanic hotspots located?
Major hot spots include the Iceland hot spot, under the island of Iceland in the North Atlantic; the Réunion hot spot, under the island of Réunion in the Indian Ocean; and the Afar hot spot, located under northeastern Ethiopia. Volcanic activity at hot spots can create submarine mountains known as seamounts.
What makes an area a hotspot?
A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.
What are hotspots geography?
A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.
How does a hot spot form?
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.
How can hot spots leave evidence of plate motion quizlet?
Because hot spots remain in place they can be used to tell the direction of plate motion in the past, as well as how fast the plates were moving.
How do hot spots provide evidence of continental drift?
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. The Hawaiian Islands form just such a chain.
Where are most hotspots located?
More than a hundred hotspots beneath the Earth's crust have been active during the past 10 million years. Most of these are located under plate interiors (for example, the African Plate), but some occur near diverging plate boundaries.
Where are the hotspots located?
Hot spots are found around the globe, on land and in the ocean. The Hawaiian Islands are the youngest volcanic mountains in a long chain of volcanoes that formed over a hotspot.
How is a hot spot formed?
A hot spot is fed by a region deep within the Earth's mantle from which heat rises through the process of convection. This heat facilitates the melting of rock at the base of the lithosphere, where the brittle, upper portion of the mantle meets the Earth's crust.
How do hotspots leave evidence of plate?
Because hot spots remain in place they can be used to tell the direction of plate motion in the past, as well as how fast the plates were moving.
What are hotspots and where are they located?
A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.

Hotspots occur when one of the Earth's plates moves over an unusually hot part of the Earth's mantle. These hot areas are usually relatively stationary and result in large amounts of magma rising up, piercing a hole in the plate to form a volcano. As the plates move, a series of volcanoes can form.
Where are hot spot volcanoes located?
Major hot spots include the Iceland hot spot, under the island of Iceland in the North Atlantic; the Réunion hot spot, under the island of Réunion in the Indian Ocean; and the Afar hot spot, located under northeastern Ethiopia.
