Pressure with Height * - The number of air molecules above a surface changes as the height of the surface above the ground changes. For example, there are fewer air molecules above the 50 kilometer (km) surface than are found above the 12 km surface. Since the number of air mole...

Scattering of Light * - Different from reflection, where radiation is deflected in one direction, some particles and molecules found in the atmosphere have the ability to scatter solar radiation in all directions. The particles/molecules which scatter light are called scatterer...

Blue Skies and Blue Haze * - Blue skies are produced as shorter wavelengths of the incoming visible light (violet and blue) are selectively scattered by small molecules of oxygen and nitrogen -- which are much smaller than the wavelength of the light. The violet and blue light has b...

It's a Breeze: How Air Pressure Affects You * - Air pressure is the force exerted on you by the weight of tiny particles of air (air molecules). Although air molecules are invisible, they still have weight and take up space. Since there's a lot of  empty  space between air molecules, air can...

WHYY Franklin Facts - Trillions and trillions of air molecules are bombarding you and me right now. Barometers are instruments that measure the force, or pressure, exerted by these molecules.
