A 200km wide impact crater near the Yucatan Peninsula is believed to be the most visual evidence yet that the dinosaurs were wiped out by an asteroid.
Trace amounts of a rare metal have been found in rock layers dating back 65 million years. It is strong evidence for an asteroid impact killing off the dinosaurs.
In this final program, presenter Tony Robinson maps out key events over the last 75,000 years. During that time humans were subjected to a super-volcano that nearly devastated whole regions of Earth. The ensuing ice age that covered Europe with ice sheets many kilometres thick is said to have thwarted the development of complex civilisation, and the cosmic catastrophe that followed is believed to have changed life forever for the early inhabitants of North America.
In episode two, Asteroid Strike, dinosaurs rose up as rulers of Earth around 230 million years ago, eventually dominating all other species and relegating mammals to the shadows. But 65 million years ago the planet was rocked by a massive event when, seemingly out of nowhere, the mighty dinosaurs were wiped off the face of Earth.
This three-part series, presented by Tony Robinson, investigates the history of natural disasters, from the planet's beginnings to the present, putting a new perspective on our existence and suggesting that we are the product of catastrophe. Episode one looks at the greatest climate disaster ever to have hit Earth. 650 million years ago, a cataclysmic ice age sealed the entire planet beneath ice and snow, almost destroying life and turning the world into one huge snowball.
On this episode, Kell and Clare are challenged to make an indoor cloud. They investigate all things atmosphere and weather, and wait until you see their mini climate inside Brainbuzz HQ. Pass or fail, you be the judge.
