Hotspot (geology) - Wikipedia
In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. [1] Examples include the Hawaii, Iceland, and Yellowstone hotspots.
Hotspots - Geology (U.S. National Park Service)
Feb 11, 2020 · 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.
Hotspot | Volcanic Activity, Plate Tectonics & Magma | Britannica
hotspot, region of Earth’s upper mantle that upwells to melt through the crust to form a volcanic feature. Most volcanoes that cannot be ascribed either to a subduction zone or to seafloor spreading at mid-ocean ridges are attributed to hotspots.
Hot Spots - Education
Oct 19, 2023 · 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.
Hot Spot Volcanism - Education
Apr 30, 2024 · Hot spot seamounts that reach the surface of the water can create entire chains of islands, such as the U.S. state of Hawai'i. Scientists think that this volcanic chain of islands has been forming for at least 70 million years over a hot spot underneath the Pacific plate.
Hotspot (geology) - Simple English Wikipedia, the free …
In geology, a hotspot or hot spot is a portion of the Earth's surface which is volcanic. This may be caused by a rising mantle plume or some other cause. [2] Hotspots may be far from tectonic plate boundaries. A volcanic hotspot is where magma pushes up from deep in the Earth's crust or mantle, and creates a volcano. The Earth's plates may move ...
2.7: Hotspots - Geosciences LibreTexts
Hotspots are the only types of volcanism not associated with subduction or rifting zones at plate boundaries; they seem totally disconnected from any plate tectonics processes, such as earthquakes. However, there are relationships between hotspots and plate tectonics.
What is a hotspot and how do you know it's there?
Scientists don’t fully understand how and why hotspots occur, and there is vigorous scientific debate about their origins. A frequently-used hypothesis suggests that hotspots form over exceptionally hot regions in the mantle, which is the hot, …
Hotspot (geology) - New World Encyclopedia
In geology, a hotspot is an area in the Earth's mantle where a column of hot magma rises up to melt through the crust, resulting in volcanic activity. The term hotspot is also used when referring to the location on the Earth's surface where such volcanism has been taking place.
5.16: Hot Spots - Geosciences LibreTexts
In geology, the places known as hotspots or hot spots are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. They may be on, near to, or far from tectonic plate boundaries.
