Which of the following statements is accurate about volcano distributions on Earth?

The statement about volcanism occurring along mid-ocean ridges is accurate because mid-ocean ridges are a primary area of tectonic activity where new oceanic crust forms due to the upwelling of magma. As tectonic plates diverge at these ridges, magma rises from the mantle to fill the gap, which leads to the formation of new volcanic islands and underwater volcanic activity. This process is a fundamental aspect of plate tectonics and is responsible for the creation of features such as the Mid-Atlantic Ridge.

Other statements suggest incorrect associations or misconceptions about volcanic activity. Some imply a relationship between volcanoes and phenomena like earthquakes without clarifying the specific contexts, while others incorrectly assert the absence of volcanic activity in specific regions. The correct understanding hinges on the fact that most volcanic activity is closely linked to tectonic plate boundaries, specifically divergent and convergent boundaries.
