What are hot spots in 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.
What is a hotspot simple definition?
Hotspot: A hotspot is a physical location where people can access the Internet, typically using Wi-Fi, via a wireless local area network (WLAN) with a router connected to an Internet service provider.
What is a hotspot in plate tectonics?
Earth > Power of Plate Tectonics > Hot Spots A hot spot is an intensely hot area in the mantle below Earth's crust. The heat that fuels the hot spot comes from very deep in the planet. This heat causes the mantle in that region to melt. The molten magma rises up and breaks through the crust to form a volcano.
How are hot spots formed geography?
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 the hotspots located?
Most of these are located under plate interiors (for example, the African Plate), but some occur near diverging plate boundaries. Some are concentrated near the mid-oceanic ridge system, such as beneath Iceland, the Azores, and the Galapagos Islands. A few hotspots are thought to exist below the North American Plate.
What is a hot spot quizlet?
Hotspot. A small area of the Earth's crust where an unusually high heat flow is associated with volcanic activity, A weak spot in the middle of a tectonic plate where magma surfaces; forms a volcano.
What makes a country a hotspot?
Hotspots have been variously described as areas of elevated incidence or prevalence, higher transmission efficiency or risk, or higher probability of disease emergence.
What is a hotspot geology quizlet?
Hotspot. A small area of the Earth's crust where an unusually high heat flow is associated with volcanic activity, A weak spot in the middle of a tectonic plate where magma surfaces; forms a volcano.
How do hotspots form quizlet?
A hotspot forms when a plume of magma rises from the mantle and melts through whatever crust is above it. This new magma tries to reach the curface and creates a volcano. But when the tectonic plate shifts, new crust is suddenly above the hotspot, and a new volcano forms.
How does a hotspot from a chain of volcanoes?
A volcanic "hotspot" is an area in the mantle from which heat rises as a thermal plume from deep in the Earth. High heat and lower pressure at the base of the lithosphere (tectonic plate) facilitates melting of the rock. This melt, called magma, rises through cracks and erupts to form volcanoes.
Why is it called a 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.
Where are some hotspots located?
Most of these are located under plate interiors (for example, the African Plate), but some occur near diverging plate boundaries. Some are concentrated near the mid-oceanic ridge system, such as beneath Iceland, the Azores, and the Galapagos Islands. A few hotspots are thought to exist below the North American Plate.
What is a hot spot in earth science quizlet?
Hot spots are mantle plumes, which are columns of hot magma rising through the mantle until it reaches the crust. The plume burns its way through the crust due to convection. This forms Shield volcanoes which typically have gentle slopes and runny lava. The plates move over the hot spot.
Where are volcanic hotspots?
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. Examples include the Hawaii, Iceland, and Yellowstone hotspots.
What are hotspots quizlet?
Hotspot. A small area of the Earth's crust where an unusually high heat flow is associated with volcanic activity, A weak spot in the middle of a tectonic plate where magma surfaces; forms a volcano.
What is a hotspot volcano quizlet?
hot spot. A volcanic region that is fed by a hot plume of magma in the mantle where magma generated by the plume rises through the rigid plates reaching Earth's surface. plume.
What is a hot spot on Earth quizlet?
Hotspot. A small area of the Earth's crust where an unusually high heat flow is associated with volcanic activity, A weak spot in the middle of a tectonic plate where magma surfaces; forms a volcano.
