K/T asteroid impact. Artwork depicting an asteroid approaching Earth about 65 million years ago. The asteroid hit the Earth at the boundary between the cretaceous and tertiary era (K/T boundary),and is thought to have contributed to the demise of the dinosaurs. Land forms are shown as they were at the time; the Yucatan Peninsula (impact site) just below centre,what is now Florida at right,Cuba to the lower right,and Mexico just below the Earth's limb. Scientists believe that the asteroid which hit Earth was up to 20 kilometres in diameter,and that the impact created six months of total darkness and decades of low global temperatures | |
