surface layers
Topmost material zones
Surface layers are the outermost portions of something—the parts exposed to air, light, or contact.
In geology and oceanography, surface layers refer to the topmost strata of earth or water: The surface layers of the ocean absorb most of the sunlight.
The term often implies depth beneath: examining only surface layers suggests superficial analysis that misses what lies below.
