History of the Scientific View on Schizophrenia as a Disease: It has been suspected for over a century that schizophrenia and manic-depressive disorder (bipolar disorder) are diseases of the brain. In 1837, Dr. W.A.F. Browne, the best-known English psychiatrist of his generation, wrote:
Best Answer: The atmosphere is divided into five layers. It is thickest near the surface and thins out with height until it eventually merges with space. 1. The troposphere is the first layer above the surface and contains half of the Earth's atmosphere. Weather occurs in this layer. 2. Many jet aircraft fly in the stratosphere because it is very stable.
The Different Levels of the Atmosphere are: Troposphere: This is the lowest atmospheric layer and is about seven miles (11 km) thick. Most clouds and weather are found in the troposphere. The troposphere is thinner at the poles (averaging about 8km thick) and thicker at the equator (averaging about 16km thick).
