Question

1. the production of fossil fuels is an interaction between which two spheres?

Explanation:

Fossil fuels are formed from the remains of ancient plants and animals that were buried and subjected to heat and pressure over long periods. These remains are part of the biosphere (living organisms and their remains). They are buried in the lithosphere (the solid outer part of the Earth, including rocks and soil). So the production of fossil fuels is an interaction between the biosphere and the lithosphere.

Answer:

Biosphere and Lithosphere
