where are hotspots usually found

Full Answer

Where are hotspots found geographically?

A hot spot is an area on Earth that exists over a mantle plume. A mantle plume is an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma.

Where are hotspots most commonly found?

the Pacific OceanMost are located around the Pacific Ocean in what is commonly called the Ring of Fire. A volcano is defined as an opening in the Earth's crust through which lava, ash, and gases erupt. The term also includes the cone-shaped landform built by repeated eruptions over time.

Where are hotspots located in the ocean?

Most hotspots, also known as "mantle plumes," occur beneath oceanic plates; Yellowstone, however, is a good example of a hotspot beneath a continental part of a plate.

What are hotspot volcanoes and where do they occur?

In geology, a hotspot is an area of the Earth's mantle from which hot plumes rise upward, forming volcanoes on the overlying crust. Samoa is composed of a linear chain of volcanic islands situated atop the Pacific tectonic plate.

Can hotspots occur anywhere?

Symptoms of Hot Spots Hot spots are typically well-defined areas of redness, swelling, and hair loss. They can occur anywhere, but are most commonly seen on the head, limbs, and hips. The affected area is moist and may discharge pus or fluid, which can lead to crusting and matting of the surrounding hair.

Are hotspots only found in oceanic crust?

Hotspots are found within continents, but not as commonly as within oceans. They are not common because it takes a massive mantle plume to penetrate the thick continental crust.

Why are there hotspot in the ocean?

Oceanic hotspots are the surface expression of rising mantle plumes from the Earth's interior and are responsible for much of the intraplate volcanism observed in the ocean basins.

What are 3 locations of hotspots on Earth?

Examples include the Hawaii, Iceland, and Yellowstone 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.

What volcanoes do hot spots form?

The Galapagos hotspot 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.

Where is the most common spot where volcanoes are formed?

Sixty percent of all active volcanoes occur at the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”

Where do volcanoes lie?

Some chains of volcanoes lie within the interiors of tectonic plates rather than along the edges. The volcanoes are progressively older away from the largest and most active volcano. 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. Several National Park Service sites lie above hotspots, or within volcanic regions formed as plates moved over a hotspot.

What is the name of the rock that forms the North American Plate?

What is plate tectonics?

Plate Tectonics—The Unifying Theory of Geology

Why are hotspots formed?

There are two hypotheses that attempt to explain their origins. One suggests that hotspots are due to mantle plumes that rise as thermal diapirs from the core–mantle boundary. The alternative plate theory is that the mantle source beneath a hotspot is not anomalously hot, rather the crust above is unusually weak or thin, so that lithospheric extension permits the passive rising of melt from shallow depths.

What is a hotspot in geology?

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. Examples include the Hawaii, Iceland and Yellowstone hotspots.

How many hotspots are there in the world?

Estimates for the number of hotspots postulated to be fed by mantle plumes have ranged from about 20 to several thousand, with most geologists considering a few tens to exist. Hawaii, Réunion, Yellowstone, Galápagos, and Iceland are some of the most active volcanic regions to which the hypothesis is applied.

What is the hotspot hypothesis?

The hotspot hypothesis is now closely linked to the mantle plume hypothesis.

Where are hotspots located?

listing possible hotspots, distinction is made between primary hotspots coming from deep within the mantle (possibly originating from the core/mantle boundary), creating large volcanic provinces with linear tracks (Easter Island, Iceland, Hawaii, Afar, Louisville, Reunion, Tristan confirmed, Galapagos, Kerguelen and Marquersas likely) and secondary hotspots derived from mantle plumes (Samoa, Tahiti, Cook, Pitcairn, Caroline, MacDonald confirmed, up to about 20 possible) at the upper/lower mantle boundary that do not form large volcanic provinces but form island chains. Other potential hotspots are the result of shallow mantle material surfacing in areas of lithospheric break-up caused by tension (and are thus a very different type of volcanism).

What type of volcanoes are hotspots?

Most hotspot volcanoes are basaltic (e.g., Hawaii, Tahiti ). As a result, they are less explosive than subduction zone volcanoes, in which water is trapped under the overriding plate. Where hotspots occur in continental regions, basaltic magma rises through the continental crust, which melts to form rhyolites. These rhyolites can form violent eruptions. For example, the Yellowstone Caldera was formed by some of the most powerful volcanic explosions in geologic history. However, when the rhyolite is completely erupted, it may be followed by eruptions of basaltic magma rising through the same lithospheric fissures (cracks in the lithosphere). An example of this activity is the Ilgachuz Range in British Columbia, which was created by an early complex series of trachyte and rhyolite eruptions, and late extrusion of a sequence of basaltic lava flows.

Why do geologists use hotspots?

Geologists have tried to use hotspot volcanic chains to track the movement of the Earth's tectonic plates. This effort has been vexed by the lack of very long chains, by the fact that many are not time-progressive (e.g. the Galápagos) and by the fact that hotspots do not appear to be fixed relative to one another (e.g. Hawaii and Iceland ).

What is a private hotspot?

The use of a private hotspot to enable other personal devices to access the WAN (usually but not always the Internet) is a form of bridging, and known as tethering. Manufacturers and firmware creators can enable this functionality in Wi-Fi devices on many Wi-Fi devices, depending upon the capabilities of the hardware, and most modern consumer operating systems, including Android, Apple OS X 10.6 and later, Windows, and Linux include features to support this. Additionally wireless chipset manufacturers such as Atheros, Broadcom, Intel and others, may add the capability for certain Wi-Fi NICs, usually used in a client role, to also be used for hotspot purposes. However, some service providers, such as AT&T, Sprint, and T-Mobile charge users for this service or prohibit and disconnect user connections if tethering is detected.

What are the legal obligations of a hotspot?

Depending upon the set up of a public hotspot, the provider of the hotspot has access to the metadata and content accessed by users of the hotspot, and may have legal obligations related to privacy requirements and liability for use of the hotspot for unlawful purposes. In countries where the internet is regulated or freedom of speech more restricted, there may be requirements such as licensing, logging, or recording of user information. Concerns may also relate to child safety, and social issues such as exposure to objectionable content, protection against cyberbullying and illegal behaviours, and prevention of perpetration of such behaviors by hotspot users themselves.

What is a hotspot device?
