Jelaskan Flood basalt events dari Peristiwa kepupusan dalam bahasa melayu

The formation of large igneous provinces by flood basalt events could have:

produced dust and particulate aerosols which inhibited photosynthesis and thus caused food chains to collapse both on land and at sea

emitted sulfur oxides which were precipitated as acid rain and poisoned many organisms, contributing further to the collapse of food chains

emitted carbon dioxide and thus possibly causing sustained global warming once the dust and particulate aerosols dissipated.

Flood basalt events occur as pulses of activity punctuated by dormant periods. As a result, they are likely to cause the climate to oscillate between cooling and warming, but with an overall trend towards warming as the carbon dioxide they emit can stay in the atmosphere for hundreds of years.

It is speculated that massive volcanism caused or contributed to the End-Permian, End-Triassic and End-Cretaceous extinctions. The correlation between gigantic volcanic events expressed in the large igneous provinces and mass extinctions was shown for the last 260 Myr. Recently such possible correlation was extended for the whole Phanerozoic Eon.
