Early symptoms of auditory nerve damage may involve hearing or balance problems as the auditory system communicates information concerning sound and body positioning to the brain. Symptoms include tinnitus, sensorineural hearing loss, dizziness, or vertigo with or without vomiting and nausea.owever, this is not usually the case. Most deaf people have conductive hearing loss due to damage in the middle ear structures. Neural hearing loss due to auditory nerve damage is much less common than conductive hearing loss and is usually irreversible.
The permanently frozen ground in the northern latitudes is called permafrost. The layer closest to the surface that thaws during the summer is also part of the permafrost, but is called the active layer.
On a glacier, the accumulation zone is the area above the firn line, where snowfall accumulates and exceeds the losses from ablation, (melting, evaporation, and sublimation). The annual Glacier equilibrium line separates the accumulation and ablation zone annually. The accumulation zone is also defined as the part of a glacierâs surface, usually at higher elevations, on which there is net accumulation of snow, which subsequently turns into firn and then glacier ice. Part of the glacier where snow builds up and turns to ice moves outward from there. Glaciers.
