The K-Pg extinction event, which wiped out the dinosaurs and around 76% of all plant and animal species on Earth, is widely believed to have been caused by a massive asteroid impact. This impact triggered catastrophic global consequences.
- Impact: A large asteroid, estimated to be about 6 miles wide, slammed into the Yucatan Peninsula in Mexico around 66 million years ago.
- Tsunamis and Earthquakes: The impact created massive tsunamis that swept across coastlines worldwide, causing widespread devastation. Earthquakes of unimaginable magnitude shook the planet.
- Wildfires: The heat from the impact ignited massive wildfires that raged for months, consuming vast areas of land and releasing huge amounts of smoke into the atmosphere.
- Climate Change: Dust and debris thrown into the atmosphere blocked out sunlight, causing a prolonged period of darkness and global cooling. This disrupted plant life, leading to a collapse in food chains.
- Acid Rain: The impact also released sulfur dioxide into the atmosphere, which formed sulfuric acid rain that poisoned water sources and further damaged ecosystems.
Pro tip: The Chicxulub crater in Mexico is the geological scar left by this catastrophic event. It's a reminder of the immense power of nature and the fragility of life on Earth.
