What kind of volcano usually forms over a hot spot?
shield volcanoes
What type of volcano is a cinder cone?
Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.
What do stratovolcanoes and cinder cone volcanoes have in common?
Cinder cones, the simplest volcano types, measure less than 300 meters high and erupt explosively. Explosive stratovolcanoes, or composite volcanoes, have steep, symmetrical, conical shapes built up over time by alternating layers of lava flows, volcanic ash, cinders and other volcanic particles.
What are the 3 types of volcano?
There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes. Figure 11.22 illustrates the size and shape differences amongst these volcanoes. Shield volcanoes, which get their name from their broad rounded shape, are the largest.
What is the most dangerous type of volcano and why?
Composite volcanoes are some of the most dangerous volcanoes on the planet. The viscous lava cannot travel far down the sides of the volcano before it solidifies, which creates the steep slopes of a composite volcano. Viscosity also causes some eruptions to explode as ash and small rocks.
What is the largest type of volcano?
shield volcano
What is the most powerful volcano on Earth?
Mauna Loa’s
Why is the stratovolcano the most dangerous?
Of all the volcanoes on Earth, stratovolcanoes are the most dangerous. They can erupt with little warning, releasing enormous amounts of material. As we saw with Mount Saint Helens, they can blast out material from the side, creating pyroclastic flows the hurtle down the volcano’s flanks at enormous speeds.
What is the oldest volcano?
Etna

Did Mt Vesuvius erupt in 2020?
In late August 2020, Mount Vesuvius erupted for the first time since 1944. The eruption was the first to be classified as VEI 9 becoming the strongest eruption ever, causing catastrophic destruction…
What states would be affected if Yellowstone volcano erupts?
Those parts of the surrounding states of Montana, Idaho, and Wyoming that are closest to Yellowstone would be affected by pyroclastic flows, while other places in the United States would be impacted by falling ash (the amount of ash would decrease with distance from the eruption site).
Will Yellowstone erupt 2020?
Yellowstone is not overdue for an eruption. The rhyolite magma chamber beneath Yellowstone is only 5-15% molten (the rest is solidified but still hot), so it is unclear if there is even enough magma beneath the caldera to feed an eruption. If Yellowstone does erupt again, it need not be a large eruption.
Who would die if Yellowstone erupted?
Should the supervolcano lurking beneath Yellowstone National Park ever erupt, it could spell calamity for much of the USA. Deadly ash would spew for thousands of miles across the country, destroying buildings, killing crops, and affecting key infrastructure. Fortunately the chance of this occurring is very low.
How many would die if Yellowstone erupted?

Which national park has the most deaths?
