The two objects that must be interacting beneath the surface during a geyser eruption are **magma and groundwater**.

In a geyser system, magma heats the groundwater, causing it to turn into steam and build up pressure until it erupts forcefully at the surface. Thus, the interaction between magma and groundwater is essential for the geyser's activity.
