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.
This is in my own words. The process of wearing away soil and rocks and carrying pieces away is called erosion. Erosion can be caused by wind, gravity, water etc. Humans can also cause erosion usually through poor land management. I need to know what the causes of erosion are and a thorough description. Water, wind, ice, gravity and temperature cause erosion.
