Hot spot volcanoes appear as volcanic chains in the middle of an oceanic plate because as the plate moves away from the hot spot, the volcano becomes less active, then the hot spot forms a new volcano.
Is my answer correct.
Sounds correct to me. Hawaii is a good example.
Yes, your answer is correct. Hot spot volcanoes, also known as intraplate volcanoes, are formed by the upwelling of magma from deep within the Earth's mantle. These hot spots are stationary, while the tectonic plates above them move. When a hot spot is situated under an oceanic plate, it can give rise to a volcanic chain.
As the oceanic plate moves over the hot spot, a volcano forms above it. Over time, the volcano becomes less active as it moves away from the hot spot. As the plate continues to move, the hot spot then creates a new volcano further along the volcanic chain. This process repeats, resulting in a trail of volcanic islands or seamounts.
One notable example of a hot spot volcanic chain is the Hawaiian Islands, where the Pacific Plate is moving northwest over the Hawaiian hot spot. The oldest islands, such as Kauai, are found in the northwest, while the youngest, including the Big Island of Hawaii, are located in the southeast.
