As it is pointed out in the passage, large igneous provinces (LIPs) ----.
The fate of the dinosaurs may have been sealed half a
billion years before life even appeared, by two
geological time bombs that still exist near our planet’s
core. A controversial new hypothesis links massive
eruptions of lava that coincided with many of the Earth’s
largest extinctions to two unusually hot sections of
mantle 2,800 kilometres beneath the Earth’s crust.
These sections formed just after the Earth itself, 4.5
billion years ago. If the hypothesis is correct, they have
periodically burst through the planet’s crust, creating
enormous oceans of lava which poisoned the
atmosphere and wiped out entire branches of the tree
of life. Debates still rage over what caused different
mass extinctions, including the one that wiped out the
dinosaurs. An asteroid that smashed into the Earth 65
million years ago is no doubt partially to blame for the
demise of the dinosaurs. But, a less-known school of
thought has it that this and other extinctions occurred
when cracks in the crust let huge amounts of lava pour
out from the centre of the Earth. Each event flooded at
least 100,000 square kilometres, leaving behind distinct
geological regions known as large igneous provinces
(LIPs), such as India’s Deccan traps, which were
formed during the time when the dinosaurs became
extinct.
