The air in our atmosphere is a mixture of gasses that varies with altitude. Oxygen makes up 21% of our atmosphere while nitrogen makes up roughly 78%...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your t...
Stage 4 –The particles rain down and interact with gasses in our atmosphere to create the light show between 75 and 800km above Earth’s surface. At different altitudes, various colours are created by interaction of electrons in the solar wind with atmospheric gasses as seen in Figure 9. ...
What is the percentage of CO2 in the atmosphere and what is the percentage of dissolved CO2 in the oceans? The second most abundant gas in the atmosphere is. When rounded to the nearest whole percent, it makes up % of the atmosphere. Which of the following groups of gases contribute to...
Put very simply, weather is the state of the atmosphere at any given period of time. The atmosphere is made up of the gasses, like oxygen, that surround the Earth. What is happening in the atmosphere is the weather. Weather includes several different factors that we can measure. Have you...
This IR radiation remains close to the earth's surface, increasing its temperature. Carbon dioxide accumulates in the atmosphere, so it has a warming effect that can affect the global climate. Currently, the concentration of CO2 in the atmosphere is about 400 ppm. However, the level is often...
Humans don’t play by the same rules that nature does. When we extract, refine, transport, and burn fossil fuels like coal, natural gas, and oil, we release extra carbon and other greenhouse gasses into the atmosphere. We also cut down large expanses of CO2-absorbing trees to make way ...
They found that the gasses did not match the makeup of Earth's atmosphere, but rather that of Mars, revealing that the little rock was in fact a meteorite from the red planet. It was dubbed the Lafayette Meteorite as a nod to the town in Indiana where Purdue University is based, and ...
根据文章内容,尤其是第一段中The answer is make air-conditioners radically better.On one calculation, replacing refrigerants(制冷剂) that damage the atmosphere would reduce totalgreenhouse gases by the equivalent of 90bn tonnes of CO2 by 2050. Making the units more energy-efficient could double that...
The four most common gases in the atmosphere are N2, O2, Ar, and CO2. Assuming all gases are in containers of equal size, temperature, and pressure, which gas has the highest density? In a beaker of boiling water, ...
They claim to help clean your air. But some air purifiers may be causing more harm than good. The problem comes from air cleaners that emit ozone. Ozone exists in abundance high in the earth’s atmosphere, but it is only found in small quantities closer to the earth’s surface. One exc...
