What best describes a major characteristic of both volcanoes and earthquake?

A major characteristic of both volcanoes and earthquakes is that they are both products of tectonic activity within the Earth's crust. They often occur along tectonic plate boundaries, where the movement of these plates can lead to volcanic eruptions or seismic events. Both phenomena are driven by the release of energy from the Earth's internal processes, which can result in significant geological and environmental impacts. Additionally, they can occur in close proximity to one another, highlighting the interconnectedness of geological processes.
