In places, bedrock has been scoured of most surficial debris.
These forces include tectonic activity and surficial earth movements (e.g., landslides and rockfalls).
The region lacks surficial traces of active fluvial processes and is dominated by eolian activity.
Calcsilitic crusts, which result from the silification of calccrusts or other surficial limestones, have been little studied in this context.
Prolonged periods of snowmelt promote perched storage in surficial soils and encourage surficial, lateral flow to preferential flow paths.
Trenching, the extension of gullies, and their conversion into arroyo systems, implies valley fills of erodible surficial material.

It is, however, more nearly aimed at actual surficial changes that pertain to landforms than were Werner's notions.

A pollution assessment based on the surficial sediment dataset by Enrichment Factor (EF) showed the surficial sediment was moderately contaminated.
