Question

Which of the following is a function of the geosphere?
a.
facilitating the movement of water through spheres through transpiration
b.
providing a moderate, livable climate
c.
facilitating the process of photosynthesis
d.
serving as the interface between the other spheres

Answer 1

d.

The geosphere is the solid Earth (rocks, soils, landforms) that provides the surface where the atmosphere, hydrosphere and biosphere meet and interact. Transpiration and photosynthesis are biological processes (biosphere), and moderating climate is mainly an atmosphere/hydrosphere function (though the geosphere can influence climate indirectly, e.g., via volcanism).
