Greenhouse Gases. You have already learned that Earth’s atmosphere is composed primarily of nitrogen and oxygen. These gases are transparent to incoming solar radiation. They are also transparent to outgoing infrared radiation, which means that they do not absorb or emit solar or infrared radiation.

INCOMING SOLAR RADIATION Larger aerosol particles in the atmosphere interact with and absorb some of the radiation, causing the atmosphere to warm. The heat generated by this absorption is emitted as longwave infrared radiation, some of which radiates out into space.

Some of the infrared radiation escapes into space, but some is stopped and absorbed by greenhouse gases in the atmosphere. In short, the absorption of infrared radiation by greenhouse gases contributes to an increase in temperature of the surface of the earth and the atmosphere.

Yes, all objects, including human bodies, emit electromagnetic radiation. The wavelength of radiation emitted depends on the temperature of the objects. Such radiation is sometimes called thermal radiation. Most of the radiation emitted by human body is in the infrared region, mainly at the wavelength of 12 micron.

Infrared radiation is popularly known as “heat radiation”, but light and electromagnetic waves of any frequency will heat surfaces that absorb them. Infrared light from the Sun accounts for 49% of the heating of Earth, with the rest being caused by visible light that is absorbed then re-radiated at longer wavelengths.

The heat that we feel from sunlight, a fire, a radiator or a warm sidewalk is infrared.

Key Features: Dubbed “Infrared,” the sneaker borrows its palette from Michael Jordan’s first championship sneaker, the Nike Air Jordan 6. This time, however, the vibrant red hue serves as the base, while the laces, tongue, liner and forefoot stabilizer standout in black.

Here is another example of how Infrared is supposed to look except on the classic Air Max 90. One of the most recent examples of Infrared we can show you is the Nike Air Trainer 1 Infrared… same pinkish hues.

Try pairing your Air Max’s with tapered joggers and a matching sweater to give a subtle nod back to the 90s, or wear joggers with a denim shirt when you don’t want to go full on athleisurewear.

The iconic Nike Air Max 90 running shoe also has a multi-lace port system and the most noteworthy feature, the large visible Air unit that provides superior cushioning among running shoes at the time.

Height: 3.1cm (1.2in) Nike Air Max 90 were first launched in 1990. Brand new, I measured a pair at between the 3 and 3.1cm range, so on your feet they should make you about 1.2 inches taller.

Nike Air Max 97 While the shoe was initially conceptualized for running purposes, it still performs surprisingly well in other aspects of life, including causal, everyday encounters, lighter training sessions, and afternoons at the gym.

Nike Air Max are NOT good for running. First of all, it’s not comfortable to run with them. You won’t be able to run correctly with Air Max and that’s the reason why your legs will hurt, they’ll become tired and heavy and you’ll lose your interest in running. Nike Air Max are good for freetime, but not for running.

Are Air Force 1s designed for working out and exercise? To be honest, they could be used for exercising in a low impact matter. Maybe for walking, but honestly, Air Force 1s are more for comfort, style and casual wear.
