Volcanoes usually form at the boundary between the Earth’s tectonic plates, which is why in America, they’re mostly concentrated in the West, Hawaii, and Alaska.
In which location would you most likely find volcanoes quizlet?
In which location would you most likely find volcanoes? along mid-ocean ridges and where a plate is subducted.
Which location would you find active volcanoes?
Many of the world’s active volcanoes are located around the edges of the Pacific Ocean: the West Coast of the Americas; the East Coast of Siberia, Japan, the Philippines, and Indonesia; and in island chains from New Guinea to New Zealand–the so-called “Ring of Fire” (diagram to left).
Where would you most likely find a hotspot volcano?
- Most volcanoes are found along convergent or divergent plate boundaries.
- The Pacific Ring of Fire is the most geologically active region in the world.
- Volcanoes such as those that form the islands of Hawaii form over hotspots, which are melting zones above mantle plumes.
What is the most active volcano in the world?
Mt Etna: The most active volcano on Earth – BBC Travel.
Can volcanoes be found underwater?
Volcanoes are common occurrences along the boundaries of Earth’s tectonic plates. … Since many plate boundaries are submerged, around three-quarters of all volcanic activity on Earth actually occurs underwater.
What is an undersea volcano called?
Seamounts. Many submarine volcanoes are seamounts, typically extinct volcanoes that rise abruptly from a seafloor of 1,000 – 4,000 meters depth. They are defined by oceanographers as independent features that rise to at least 1,000 meters above the seafloor.
Where is the Ring of Fire?
The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. Its length is approximately 40,000 kilometers (24,900 miles).
Can volcanoes happen anywhere?
Volcanic eruptions do not occur just anywhere. … Where the plates are moving apart or colliding with one another, volcanoes may form. Many volcanoes form oceanic islands in the Pacific Ocean or Mediterranean Sea. These volcanoes formed over “hot spots” in the crust and mantle.
Is lava underwater?
What Types of Lava Flows Are There Underwater? Lava erupting on the deep sea floor has a form most like pahoehoe flows. Three types of lava flows are common on the sea floor: pillow lava, lobate lava, and sheet lava. … As lava erupts on the ocean floor, its outer surface cools and solidifies immediately.
Do volcanoes only exist on land?
Volcanic eruptions occur only in certain places and do not occur randomly. … Although most of the active volcanoes we see on land occur where plates collide, the greatest number of the Earth’s volcanoes are hidden from view, occurring on the ocean floor along spreading ridges.
Which country has no volcano?
Even though Australia is home to nearly 150 volcanoes, none of them has erupted for about 4,000 to 5,000 years! The lack of volcanic activity is due to the island’s location in relation to a tectonic plate, the two layers of the Earth’s crust (or lithosphere).

With more than 13,000 islands, Indonesia leads the world with the largest number of active volcanoes. The areas volcanoes have also produced the most fatalities.

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.
Where in earth do hotspots originate?
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.
Do hot spots move?
Hotspots are places where plumes of hot, buoyant rock from deep in the Earth’s mantle plow to the surface in the middle of a tectonic plate. They move because of the convection in the mantle that also pushes around the plates above (convection is the same process that happens in boiling water).
Where is largest volcano?
Mauna Loa on the Island Hawaiʻi is the world’s largest volcano.
