Models of Geosystems Practice Test

A student draws a simplified model of how sediment moves (it leaves out many steps):

Geosphere (mountain rock) --(erosion)--> Hydrosphere (river carries sediment)

Hydrosphere --(deposition)--> Geosphere (delta deposits)

Atmosphere --(wind)--> Geosphere (moves sand)

Which part of the model is incorrect or misleading based on Earth systems cycling matter?

A simplified model traces water and shows system interactions (it leaves out many pathways):

Hydrosphere (lake) --(evaporation)--> Atmosphere

Atmosphere --(precipitation)--> Geosphere (ground)

Geosphere --(infiltration)--> Hydrosphere (groundwater)

Biosphere (animals) --(drinking)--> Biosphere (animals)

What is incorrect about this model?
