Flu-like Illness. One of the earliest HIV symptoms in men is a severe 'flu-like' illness, known as the 'seroconversion illness.'. Seroconversion is the point in time where a person's blood is converted from being HIV negative to HIV positive, by the production of antibodies.
Erosion causes the surface of mountains to be younger than the rocks that form the mountains themselves. Glacial processes produce characteristic landforms, such as pyramidal peaks, knife-edge arÃªtes, and bowl-shaped cirques that can contain lakes.
These can cause earthquakes, but that does not cause the mountain to form, just a symptom. For instance the Indian sub-continent is pushing northward into Asia and meeting resistance. The result is uplift and the Himalayan Mountains are formed and still growing.
