A volcanic eruption releasing rock, ash, and dust particles into the air is an example of which interaction?

A volcanic eruption releases rock, ash, and dust from the solid Earth, which is part of the geosphere, into the air, which is part of the atmosphere. Therefore, it is the geosphere interacting with the atmosphere. The hydrosphere refers to Earth's water, so choices involving it do not fit.
