How did volcanic activity trigger a global deep freeze over 600 million years ago?
In short: More than 600 million years ago, Earth was encased in ice across both land and sea. This video examines the evidence for this Snowball Earth phenomenon and investigates the mechanisms that caused the planet to freeze and eventually thaw.
Evidence for the Snowball Earth period is preserved on every continent, providing a geological record of a time when the entire planet was covered in ice. Researchers study these remnants to understand how the climate shifted so drastically.
The video explores the conditions that led to this global glaciation and the subsequent warming that allowed life to persist. By analyzing these ancient climate cycles, scientists gain insight into the planet's resilience and the factors that govern its long-term temperature regulation.
