what is a hot spot quizlet

what is a hot spot quizlet
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 causes hot spots quizlet?

How are vocanic hotpsots created? When ‘plumes’ of magma rise through the Earth’s mantle. This build up of magma beneath the surface will eventually create volcanic activity on the ocean floor as it breaks through the structurally weak areas.

How many hotspots are there?

There are currently 36 recognized biodiversity hotspots. These are Earth’s most biologically rich—yet threatened—terrestrial regions. To qualify as a biodiversity hotspot, an area must meet two strict criteria: Contain at least 1,500 species of vascular plants found nowhere else on Earth (known as “endemic” species).

How does an area qualify to be a hotspot quizlet?

What determines/identifies a biodiversity hotspot? It must have at least 1,500 vascular plants as endemics — which is to say, it must have a high percentage of plant life found nowhere else on the planet. A hotspot, in other words, is irreplaceable. It must have 30% or less of its original natural vegetation.

What type of high-speed network is normally set up in a person’s home quizlet?

Most wired networks for the home are Ethernet networks. What kind of wire do I use to set up an Ethernet network? The most popular transmission media option for wired home Ethernet networks is unshielded twisted-pair (UTP) cable.

What type of network topology connects a peripheral device to a host device?

In star topology, every peripheral node (computer workstation or any other peripheral) is connected to a central node called a hub or switch.

What device connects a network to the Internet through an Internet service provider quizlet?

Correct. The cable modem is the hardware device used to connect the local area network (LAN) to a cable Internet service provider (ISP). The cable is a broadband technology transported over a coaxial cable that can provide high-speed Internet, TV, and voice via a single cable connection.

Which type of volcanoes are formed by hotspots?

As hotspot material rises, the pressure drops so the hotspot begins to melt producing magma. In an oceanic hotspot environment, for example Hawaii, dark, silica-poor basalt magma is produced. The runny basalt forms broad sloping shield volcanoes (Fig. 6).

How do volcanoes form over hotspots?

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. As the tectonic plate moves over the stationary hot spot, the volcanoes are rafted away and new ones form in their place.

What is accurate about a typical volcano formed by eruptions from a hot spot?

What is accurate about a typical volcano formed by eruptions from a hot spot? The lava of the volcano is mostly basaltic in composition, with gradual sides where the volcano projects above sea level, but steeper sides on undersea portions.

How do hot spots help us understand plate tectonic processes and rates?

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. While the hot spot stays in one place, rooted to its deep source of heat, the tectonic plate is slowly moving above it.

How do geologists use hot spots to understand plate motion?

Above the plumes, you get hot spots, where rock melts into magma. … It allowed them to track the movement of tectonic plates, because as the plates moved over a stationary hot spot, they left a trail, or chain, of old volcanoes behind them.

How do Hotspots help us understand plate tectonic processes and rates?

The lava cools down and forms a volcano. The hot spot itself never changes position, but the tectonic plates are constantly moving, so the volcano formed will “move” along with the tectonic plate to the direction where ever the tectonic plate is heading, but at the same time the hot spot doesn’t stop producing lava.

How hot spots are formed?

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 hotspots found?

Hot spots are found in the ocean, and on continents. Often the hot spot creates a chain of volcanoes, as a plate moves across a relatively stationary mantle plume. The best example of a hot spot volcanic chain is the Hawaiian Islands.

What are hotspots in biology?

A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. … Some of these hotspots support up to 15,000 endemic plant species and some have lost up to 95% of their natural habitat.

What are hotspots and how did they form the Hawaiian Islands quizlet?

-Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the sea floor, at what is called a “hot spot.” -The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate.

What is another word for hotspot?

What is another word for hot spot?

asperity bad news

How are hotspots distributed?

Hot spots have an irregular distribution over the earth’s surface. … To the first order, hot spots are concentrated on one half of the surface area of the earth; within that portion, the distribution is consistent with a uniform distribution.

Is the Dixie fire still burning?

The Dixie Fire Incident Team confirmed to ABC10 the largest wildfire of the 2021 fire season came to a close as of Sunday evening. SACRAMENTO, Calif. — Burning almost one million acres across Northern California, the Dixie Fire is 100% contained after more than three months of destruction.
