Models of Geosystems Practice Test

A student drew a simplified Earth system model to show water cycling. The model is meant to show interactions among systems, but one important connection is missing.

Based on the model, which missing arrow would best complete the cycling of water between systems?

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?
