Nitrogen is the most stable atmospheric element because it exists as diatomic molecules joined by exceptionally strong triple covalent bonds. Breaking these bonds requires massive energy, such as a lightning strike, making nitrogen chemically inert under normal conditions. This stability ...
The Deccan Traps were formed nearly 66 million years ago by fissure eruptions, where highly fluid basaltic lava flowed out of long cracks in the Earth’s crust. This “flood basalt” covered over 500,000 square kilometers, creating a stepped (trap) landscape. ...
