Final answer:
Shield Volcanoes, known for their non-violent eruptions, are commonly found at mid-ocean ridges and at 'hot spots' in the sea. These are areas where tectonic plates move apart and magma rises.
Step-by-step explanation:
The type of volcanoes that do not erupt violently and are generally found at mid-ocean ridges or at hot spots in the sea are known as Shield Volcanoes.
These volcanoes are formed by effusive eruptions, where lava flows gently out of the volcano, leading to the build-up of broad, shield-shaped mountains. A good example of this type of volcano is found in Hawaii.
Mid-ocean ridges represent locations where tectonic plates are diverging or moving apart. As the plates move apart, magma rises from the mantle to fill the gap, leading to the formation of new crust
And, frequently, the eruption of undersea volcanoes. Similarly, 'hot spots' are areas where heat from the Earth's mantle rises up, resulting in volcanic activity. The Hawaiian Islands, for example, were formed by a hot spot beneath the Pacific Plate.
Therefore, Shield Volcanoes, known for their gentle eruptions and characteristic shape, are commonly found at mid-ocean ridges and hot spots.
