What you’ll learn

  1. A scar hidden in plain sightLocate Chicxulub and explain how geophysics reveals a buried crater.A quiet Yucatan landscape hides a multi-ring structure visible through radar, gravity, and seismic evidence.
  2. The collision in minutesDescribe how an impactor made a complex crater and displaced ocean, rock, and atmosphere.Shock, rebound, ejecta, and tsunami transformed a shallow sea into a geological record.
  3. The day becomes a yearTrace the environmental chain from ejecta and sulfur to darkness, cooling, and food-web stress.The collision was brief, but its atmospheric and ecological consequences lasted much longer.
  4. How we know the day happenedWeigh the global boundary layer and multiple independent lines of evidence.A local crater, global chemistry, and fossil timelines converge without relying on one perfect witness.
  5. A crater you can drillExplain why cores and recovery studies extend the story beyond the blast.Drilling reveals the crater's structure and the long, uneven return of life.

Questions this course answers

Why is Chicxulub difficult to see from the surface?

The crater is mostly buried, so radar, gravity, seismic data, and drilling reveal it.

What is an impactor in this story?

Impactor names the body whose kinetic energy made the crater and ejecta.

Why does the K-Pg boundary support a Chicxulub connection?

Iridium, spherules, shocked minerals, and matching age connect distant rocks to the impact.

What did drilling the peak ring make possible?

Cores preserve textures and minerals that record crater formation and later alteration.

What should you notice when thinking about recovery?

The impact took minutes; climate disruption, recolonization, and geological alteration continued far longer.
