Atmosphere.. layer of the atmosphere

The atmosphere of the Earth may be divided into several distinct layers, as the following figure indicates. Layers of the Earth's atmosphere The Troposphere The troposphere is where all weather takes place; it is the region of rising and falling packets of air. The air pressure at the top of the troposphere is only 10% of that at sea level (0.1 atmospheres). There is a thin buffer zone between the troposphere and the next layer called the tropopause. The Stratosphere and Ozone Layer Above the troposphere is the stratosphere, where air flow is mostly horizontal. The...

atmospheric pressure

Atmospheric Pressure force exerted by the weight of the air Atmospheric pressure is defined as the force per unit area exerted against a surface by the weight of the air above that surface. In the diagram below, the pressure at point "X" increases as the weight of the air above it increases. The same can be said about decreasing pressure, where the pressure at point "X" decreases if the weight of the air above it also decreases. Thinking in terms of air molecules, if the number of air molecules above a surface increases, there are more molecules to exert a force on that surface and...

The atmosphere

The atmosphere of Earth is a layer of gasessurrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperatureextremes between day and night (the diurnal temperature variation). The common name given to the atmospheric gases used...
