The scenario that describes an interaction between two of Earth's spheres is "bears dig big holes in the ground to protect their young".

Explanation:

The Earth spheres include the biosphere, the hydrosphere, the geosphere, and the atmosphere. In this context, there is an interaction between two spheres: the biosphere and the geosphere, when a bear digs holes in the ground because a living organism that is part of the biosphere is modifying the structure and shape of superficial soil, which is part of the geosphere.
