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.
Far north in the land of northern lights and the midnight sun, soils form that are partially frozen year round. These soils are also found on mountaintops. Most of these soils have permafrost, which is soil that is frozen year round.At the surface, freezing and thawing creates very special landforms and patterns in these soils. They are not used for agricultural productivity, but they help form a special habitat for lots of different types of wildlife.ost of these soils have permafrost, which is soil that is frozen year round.
