Earth and Mars - One Wet, One Dry - Why the Difference?

Explore the divergent paths of Earth and Mars in this 46-minute lecture presented by Dr. Donald Henderson of the Royal Tyrrell Museum of Palaeontology. Delve into the fascinating journey of two planets that began similarly 4.6 billion years ago as warm, wet worlds, but evolved drastically differently over time. Discover the factors that have kept Earth warm, wet, and teeming with life, while Mars has become cold, dry, and seemingly lifeless. Uncover the geological, atmospheric, and planetary processes that have shaped these contrasting outcomes, gaining insights into the complex interplay of forces that determine a planet's habitability.
