Fact Check: "The Earth's atmosphere is composed of 78% nitrogen and 21% oxygen."

What We Know

The Earth's atmosphere is primarily composed of nitrogen and oxygen, with nitrogen making up approximately 78% and oxygen about 21% of the atmosphere by volume. According to the NOAA, nitrogen is the most abundant gas in the atmosphere, serving to dilute oxygen and prevent rapid combustion. The Composition of the Atmosphere confirms that nitrogen constitutes 78.084% and oxygen 20.948% of the atmosphere. Additionally, the UCAR Center for Science Education states that nitrogen is the most prevalent gas at about 78%, with oxygen following at around 21%.

Analysis

The claim that the Earth's atmosphere is composed of 78% nitrogen and 21% oxygen is supported by multiple credible sources. The NOAA, a reputable scientific organization, provides detailed information about atmospheric composition, emphasizing the dominance of nitrogen and oxygen in the air we breathe. The Composition of the Atmosphere source offers precise percentages, reinforcing the accuracy of the claim. Furthermore, the UCAR source corroborates these figures, indicating that they are widely accepted in the scientific community.

While there are slight variations in the exact percentages reported (e.g., 78.084% nitrogen and 20.948% oxygen), these differences are negligible and do not contradict the claim. The minor fluctuations in gas composition can be attributed to environmental factors such as humidity and altitude, as noted in the NOAA report.

The sources used are reliable and authoritative, coming from established scientific organizations and educational institutions. Their consensus on the composition of the atmosphere lends significant weight to the claim.

Conclusion

Verdict: True
The claim that the Earth's atmosphere is composed of 78% nitrogen and 21% oxygen is accurate. This conclusion is supported by multiple credible sources that consistently report these figures, confirming their validity within the scientific community.

Fact Check: MASSIVE bolt of plasma burst out of the sky striking I-40 near Alma, Arkansas last night! They're getting larger and more frequent as the Earth continues charging up. The further the magnetic North Pole continues racing toward Siberia the weaker Earth's protective magnetic shield becomes. More cosmic radiation from space and more UV, UVB, and UVC radiation from the Sun are penetrating deeper into our atmosphere and into the Earth. Earth's atmosphere is becoming highly charged and electrified causing massive plasma bursts like this to strike, causing more lightning strikes period. Lightning has even been documented striking on days without a storm cloud in sight. All the signatures of the binary twin solar system and the Destroyer's arrival just amplified dramatically this year. The alarmingly endless rainfall and flooding across the world is something I have never witnessed before in my ten years of reporting Earth's climate disasters. Folks who know weather for 60 - 70 years have never witnessed the sudden incredible down bursts of several inches of rain in just minutes that have been triggering nonstop catastrophic flash flooding across America and the rest of the world. It's just been nonstop this year. I've never seen so many very strong and powerful earthquakes strike since March when the 7.0+, 6.0+, 5.0+ magnitude earthquakes accelerated in frequency so fast. With aftershocks in numbers we've never seen before, in the hundreds. I've never seen so many fires breaking out across the world that just keep coming. Canada, the United States, the entire Mediterranean region, Europe, etc. The core of the Earth is expanding from the increase in radiation causing the rock to melt underneath our feet. Magma plumes are growing, lava tubes and corridors are expanding globally and reaching the Earth's surface, on land and under water. We've got a rash of volcanic activity on land and on the ocean floor heating up the water, melting the poles, causing marine life die offs, and fueling the atmosphere with high humidity and water vapor for more frequent and intense storming. All the symptoms of the arrival of the binary twin solar system that was expected are being checked off. This will just continue to worsen in the coming days. Mid-August is almost here and watching for the extreme weather to intensify. We're heading into severe birth pangs now. Listening for updates and watching it unfold live. Remarkable days.
