Chicxulub crater reshaped Earth on a massive scale

Chicxulub crater spans 200 km.

An asteroid 10 kilometers wide made the crater 66 million years ago.

The impact released energy equivalent to billions of megatons of TNT.

Geological rock layer marks the Cretaceous–Paleogene boundary.

A transient cavity 100 kilometers wide and 30 kilometers deep formed.

Sediment moved by the impact covered the Gulf of Mexico deeply.

Around 600 meters of ocean sediment now covers parts of the crater.

The crater's inner peak ring formed as Earth rebounded after impact.

Peak ring rocks lie about 800 meters below the ocean floor today.

Scientists drill cores to study the crater and its impact on life.

Asteroid impact created the Chicxulub crater in Mexico.
