9. In the mid-1800's, the New Almaden mercury mines of south San Jose pro the mines in the Sierra Foothills. The mercury was used in the processing a gold. However, the mining also helped to release mercury, which is toxic to streams and bodies of water in the area. It is not possible today to eat fish f Bay or from the Guadalupe River because of the high-levels of mercury tha This shows an example of the interaction of which three spheres? A) Atmosphere-Hydrosphere-Biosphere B) Geosphere-Atmosphere-Cosmopshere C) Geosphere-Hydrosphere-Biosphere D) Geosphere-Biosphere-Atmosphere

The geosphere refers to the materials in and under the surface it such as rocks, minerals, among others that are part of the Earth. On the other hand, the hydrosphere covers all water bodies such as rivers, oceans, waterfalls, etc. And the biosphere includes all forms of life.

In this way, in the case presented, there is an interaction between the Geosphere, Hydrosphere, and Biosphere as the gold extracted and the use of mercury to extract this belong to the Geosphere, additionally the streams and bodies that were contaminated belong to the Hydrosphere and the animals and people affected by this situation are part of the Biosphere.
