What is hotspot volcanism 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 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 are hotspots formed 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.
What are hot spots in volcanism?
Hot Spots. 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 are hotspot volcanoes formed 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. This is how hotspot volcanoes form.
What happens at a hotspot?
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 is a hotspot quizlet computer?
A public location that offers computer network access via a Wi-Fi connection. Hotspot. A website or group of web pages on which anyone can add, edit, or delete content.
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.
How do hotspots cause volcanoes?
How do hotspots work volcanoes?
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.
What does tethering two mobile devices mean quizlet?
Tethering is connecting one device to another. In the context of mobile phones and tablet computers, tethering allows sharing the Internet connection of the phone or tablet with other devices like laptops.
Why are hotspots formed?
What causes a hotspot?
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.
What do hotspots produce?
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.
Why do hotspots form volcanic island chains quizlet?
How does a chain of volcanoes, or volcanic island form? 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.
What does tethering two mobile devices mean?
Tethering is the practice of using a mobile device (such as a smartphone) as a modem to connect another device, such as a laptop or another mobile phone to the Internet. To do so, the phone must have mobile data enabled.
