Some say the impact at Chicxulub crater in Mexico triggered a period of large volcanic

eruptions, turning Earth’s atmosphere into a dusty, noxious mess for the next 500,000 years

as to how the dinosaurs died off..... Perhaps the tremendous energy of the Chicxulub impact

which has been compared to a magnitude 11 earthquake—shook up volcanoes

worldwide, inciting a period of larger and more deadly eruptions?

Like a one-two punch!

The impact probably broke up the crust of the Earth and started or accelerated the process of Continental Drift.

Most likely the Gulf of Mexico was not there at the time, but may have been a shallow swamp.
