How about astroid strikes that caused massive volcanic activity?
I would think that would be a very good possibility... depending where it hit..
Doesn’t really matter.
Every stage of development of the Earth, from the oxygenation by algae, the era of the conifers, the era of the dinosaurs, etc,
all were for the _purpose_ of making a habital planet for human beings to thrive on and to discover the wonders of God’s universe from.
It is interesting to see how these things unfolded, though.
India was once an island. Would the volcanic activity have coincided with the landmass colliding with Asia?
Some scientists contend that a supervolcano was about to explode, but it was plugged up just in the nick of time by an incoming asteroid.
It’s been proposed that big impacts cause volcanism on the OPPOSITE side of the earth through focusing of seismic energy there.
Very controversial though.
I was thinking the same thing. You would think that a sufficiently massive strike would cause shock waves through the mantle that would trigger earthquakes and eruptions
The timing isn't all that clear (yet) but I wouldn't be a bit surprised to find that an impact large enough to ring the planet like a bell could trigger massive vulcanism.
I suspect magma may be somewhat thixotropic and flow to the surface much more easily under immediate post impact conditions.
I also think an impact would jar out dissolved gases and 'pump' magma towards the surface. Compare to what you see in a sealed soda bottle when you smack it one!
