are the aleutian islands a hotspot?
7557
Hotspot volcanoes are considered to have a fundamentally different origin from island arc volcanoes. The latter form over subduction zones, at converging plate boundaries. ... It is this that fuels a chain of volcanoes, such as the Aleutian Islands, near Alaska.

An island volcanic arc forms in an ocean basin via ocean-ocean subduction. The Aleutian Islands off the coast of Alaska and the Lesser Antilles south of Puerto Rico are examples. A continental volcanic arc forms along the margin of a continent where oceanic crust subducts beneath continental crust.

Scientists believe that Mauna Kea began erupting about 1 million years ago. It's fed by magma from the Hawaiian hotspot; a volcanic vent that continues to pump out magma while the Pacific Plate slowly moves over top of it. This has created a chain of islands thousands of kilometers long called the Hawaiian archipelago.

The northwest moving Pacific Plate has moved across the 'hot spot' that created the Hawaiian Islands for millions of years. This movement has left the northwest trending island chain (of over 20 islands and atolls) we call Hawaii.

Answer and Explanation: Kilauea is on the Pacific plate. The Hawaiian islands are not located at a plate boundary. They are roughly in the middle of the Pacific plate.

Rat Island, like many other treeless, volcanic islands in the 1,000-mile (1,609-km) long Aleutian chain, is infested with rats that have proved devastating to wild birds that build nests in the earth or in rocky cliffs. ... Rats are a problem shared by remote islands all around the world.

Hotspots are stationary magma plumes deep in the Earth that create volcanoes on the surface (eg Mount Kilauea in Hawaii). On a hotspot, magma comes to the surface through cracks in the rocks with great heat and low pressure. Hotspots can be linked to plate margins or may just form on a crustal plate.

The islands are a paradise. A lot of people think the Pacific is filled with expensive islands and resorts. But that's not true and visit to the Cook Islands will prove that. Visiting these islands are pretty affordable compared to neighboring countries.

Which answer choice best describes the difference between island arcs and hotspot volcanoes? Island arcs form when two oceanic plate boundaries push against each other until subduction happens and the plates partially melt, whereas hotspot volcanoes form when hot, fluid rock rises through thin spots in Earth's crust.

Mount Cleveland, also known as Cleveland Volcano and Chuginadak, is one of the most active volcanoes in the central part of the Aleutian island arc. It is a stratovolcano that comprises the entire western half of Chuginadak Island.

In which direction was the crustal plate apparently moving when the Hawaiian Islands were forming? Northwest, because the youngest island Hawaii is southeast from older islands like Kauai and Oahu. Hawaii is the youngest volcano so that means it formed at the hot spot and it pushed the other volcanic islands northwest.
