The Wet Adiabatic Lapse Rate occurs when rising air becomes saturated and water vapor begins to condense into liquid droplets. This condensation releases “latent heat,” which warms the surrounding air. Consequently, saturated air cools more slowly (about 5°C per km) ...
The ozone layer specifically excels at absorbing UV-B radiation (280–315 nm). While it absorbs all UV-C radiation (the most dangerous), UV-B is the wavelength that partially reaches the surface and causes sunburn, skin cancer and cataracts. By absorbing most of ...
Noctilucent clouds or “night-shining” clouds, are composed of tiny ice crystals. They form in the mesosphere, the highest part of the atmosphere, at altitudes of about 76 to 85 kilometers. They are only visible during deep twilight when the sun ...
The twinkling of stars, known as stellar scintillation, is caused by atmospheric refraction. As starlight passes through different layers of the atmosphere with varying densities and temperatures, the light is bent multiple times. Since the atmosphere is constantly moving due ...
