Question

What is an example of a place formed by hot-spot valcanoes?

Answer 1

The Hawaiian islands were formed by hot spots. Hot spots are areas deep in the mantle where magma rises in cracks and fissures. The tectonic plate moves over the hot spot, which eventually cools to form the island.

Answer 2

Answer:

The correct answer is D. An example of a place formed by hot-spot volcanoes are the Hawaiian Islands.

Explanation:

The Hawaiian Islands form an archipelago of nineteen islands and atolls, plus other small barren islands, reefs and sand banks, in an alignment of the northwest to south-east along 2,400 km in the north Pacific.  

The islands of the archipelago are the peaks that stand out from a large underwater mountain range formed by volcanic activity. Located approximately 3,000 km from the nearest continent, America, it is the most isolated archipelago on Earth.

This archipelago developed when the Pacific plate moved slowly north-west on a hot spot in the Earth's mantle at a speed of about 51 km every million years. This is why, as they are more exposed to erosion, the islets of the north-west end of the archipelago are older and generally smaller.

Almost all the magma of the hot spot is composed of gleam and so the volcanoes of Hawaii consist almost exclusively of this igneous rock.

On the islands of Hawaii there are many earthquakes, generally caused by volcanic activity. The islands are also prone to tsunamis caused by earthquakes that occur in relatively distant locations in the Pacific.
