Scientists believe that an asteroid impact caused the Cretaceous extinction event 66 million years ago. An impact crater off the coast of Mexico's Yucatan Peninsula is evidence for this theory. The asteroid hit Earth at a high velocity, which destroyed the surrounding area and sent a large amount of materials into the atmosphere, blocking sunlight globally. Which BEST describes how the asteroid impact caused this extinction event?
The initial impact destroyed all the species on Earth.
The initial impact did not destroy any of the species on Earth.
The initial impact destroyed only the species in the surrounding areas.
The initial impact destroyed nearby species and more were destroyed after.

The initial impact destroyed nearby species and more were destroyed after.
The strike caused immediate, massive local destruction (blast, heat, shockwaves, tsunamis, fires) and threw dust, soot, and aerosols into the atmosphere that blocked sunlight, cooled the climate, and disrupted food chains — causing widespread extinctions worldwide after the initial impact.
