A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. [1]
The reddish color of the Sun when it is observed through a thick atmosphere, as during a sunrise or sunset. This is because long-wavelength (red) light is scattered less than blue light. The red light reaches the observer's eye, whereas the blue light is scattered out of the line of sight. Other colours in the sky, such as glowing skies at dusk ...
The Earth's atmosphere is the origin of the weather phenomena studied in meteorology. Atmospheric composition, temperature, and pressure vary across a series of distinct sublayers including the troposphere and stratosphere. The properties of Earth's atmosphere vary by altitude across a series of distinct layers. atmospheric boundary layer (ABL)
According to the American National Center for Atmospheric Research, "The total mean mass of the atmosphere is 5.1480 × 10 18 kg with an annual range due to water vapor of 1.2 or 1.5 × 10 15 kg, depending on whether surface pressure or water vapor data are used; somewhat smaller than the previous estimate.
Atmospheric chemistry is a branch of atmospheric science that studies the chemistry of the Earth's atmosphere and that of other planets. This multidisciplinary approach of research draws on environmental chemistry, physics, meteorology, computer modeling, oceanography, geology and volcanology, climatology and other disciplines to understand both natural and human-induced changes in atmospheric ...
As its heated, the components in the retardant prevent the cellulose in plant matter from fueling the fire, according to Perimeter Solutions. It instead emits water vapor as it decomposes, which ...
Airglow over Auvergne, France Yellow, green and red bands of airglow along Earth's limb as seen from space. Airglow (also called nightglow ) is a faint emission of light by a planetary atmosphere . In the case of Earth's atmosphere , this optical phenomenon causes the night sky never to be completely dark, even after the effects of starlight ...
