Sentences with phrase «ultraviolet radiation heats»

Not exact matches

Testing showed their materials were biocompatible, stood up well in heat and light, and absorbed both ultraviolet A and ultraviolet B radiation with high efficiency.

While lower - energy ultraviolet radiation breaks up water molecules — a process called photodissociation — ultraviolet rays with more energy (XUV radiation) and X-rays heat the upper atmosphere of a planet, which allows the products of photodissociation, hydrogen and oxygen, to escape.

In addition to the coronal heating mystery, IRIS will shed light on the processes that drive the solar wind, solar storms, ultraviolet radiation and other phenomena that can hinder electronic communications and negatively affect human health on Earth.

This initially leaves it stranded inside the decaying host, so it has to protect itself, perhaps for years, against adverse environmental conditions such as heat, ultraviolet radiation and drought, until it is once again ingested by an insect.

Ultraviolet radiation spices things up as well: It heats the grains and breaks up some of the molecules into reactive fragments, which in turn bond with other fragments to form new kinds of molecules.

When the star's ultraviolet radiation strikes the gases in the nebula, they heat up, giving out radiation ranging in wavelength from blue — emitted by hot oxygen in the bubble near the star — to yellow — emitted by hot hydrogen and nitrogen.

When gas falls toward the black hole at the center of the galaxy NGC 4151, the gas heats up and emits ultraviolet radiation, which in turn heats the ring - shaped dust cloud orbiting the black hole at a distance.

Earth and the sun are deeply and intricately connected, not only by simple rays of light and heat, but also by a complex web of electricity, magnetism, solar wind and extreme ultraviolet radiation.

The formation of a stratosphere layer in a planet's atmosphere is attributed to «sunscreen» - like molecules, which absorb ultraviolet (UV) and visible radiation coming from the star and then release that energy as heat.

On the other hand both records have shown dramatic cooling in the stratosphere, where cooling is indeed expected due to increasing greenhouse gases and decreasing ozone (which heats the stratosphere due to its absorption of solar ultraviolet radiation).

The cell also overcomes some of the major problems with current solar tech like wear out or damage from high heat that comes from the absorption of great amounts of ultraviolet and infrared radiation that can't actually be turned into electricity due to a narrow band gap (the wavelength of light that can effectively be used to generate electricity).

The Met Office state «The «greenhouse effect» is the way the atmosphere traps some of the energy we receive from the Sun (infrared radiation or heat, ultraviolet and visible light) and stops it being transmitted back out into space».

The pattern of temperature increase with height in the stratosphere is the result of solar heating as ultraviolet radiation in the wavelength range of 0.200 to 0.242 micrometre dissociates diatomic oxygen (O2).

Ozone absorbs incoming solar ultraviolet, leading to heating, which is balanced by thermal radiation from the greenhouse gases in the stratosphere.

Radiation at ultraviolet wavelengths dissociates atmospheric molecules, initiating chains of chemical reactions — specifically those producing stratospheric ozone — and providing the major source of heating for the middle atmosphere, while radiation at visible and near - infrared wavelengths mainly reaches and warms the lower atmosphere and the Earth's surface1.

A rooftop is an extreme environment with strong and variable wind patterns and little or no protection from the sun's intense heat and ultraviolet radiation.

The soot would absorb enough solar radiation to heat surrounding gases, setting in motion a series of chemical reactions that would break down the stratospheric ozone layer protecting Earth from harmful ultraviolet radiation, said Mills.

The soot would absorb enough solar radiation to heat surrounding gases, setting in motion a series of chemical reactions that would break down the stratospheric ozone layer protecting Earth from harmful ultraviolet radiation.»
