Question

DEFEND the statement that the large mountains of the hawaiian islands did not form at a plate boundary (10-30 words and I'll give you brainlest), copied because somebody stole my points

Answer 1

Answer:

Here is the answer mark me as brainlest

Explanation:

The Hawaiian Emperor seamount chain is a well-known example of a large seamount and island chain created by hot-spot volcanism. Each island or submerged seamount in the chain is successively older toward the northwest. Near Hawaii, the age progression from island to island can be used to calculate the motion of the Pacific Oceanic plate toward the northwest. The youngest seamount of the Hawaiian chain is Loihi, which presently is erupting from its summit at a depth of 1000 meters. Image courtesy of U.S. Geological Survey.

The Earth’s outer crust is made up of a series of tectonic plates that move over the surface of the planet. In areas where the plates come together, sometimes volcanoes will form. Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the seafloor, 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. While the hot spot itself is fixed, the plate is moving. So, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed.

The Hawaiian Islands form an archipelago that extends over a vast area of the North Pacific Ocean. The archipelago is made up of 132 islands, atolls, reefs, shallow banks, shoals, and seamounts stretching over 1,500 miles from the island of Hawaii in the southeast to Kure Atoll in the northwest.

Answer 2

• The Hawaiian islands were formed by a volcanic hot spot, an upwelling plume of magma, that creates new islands as the pacific plate moves over it.
• The eight primary islands that makes up this archipelago over their existence to a rolling spot of magma deep under the ocean floor known as the Hawaii hotspot....
• On the more ancient landmasses, the volcanoes are no longer active because they have been cut off from the hotspot's supply of magma.
• Convergent plate boundaries are also called subduction zones and are typified by the Aleutian Trench, where the Pacific Plate is being subducted under the North American Plate.
• While most islands form near tectonic plate boundaries, the Hawaiian islands are nearly 2000 miles away from the nearest plate margin.
• Therefore, scientists believe that the islands formed due to the presence of the Hawaiian "HOT SPOT", a region deep in the Earth's mantle from which heat heat rises.
