Marie Tharp was a pioneering cartographer whose detailed maps of the Atlantic Ocean floor revealed the Mid-Atlantic Ridge and provided crucial evidence for the theory of plate tectonics, overcoming significant gender barriers and transforming earth science. Her work, initially overlooked, has gained recognition and continues to inspire oceanographic exploration today.

The breakup of the ancient supercontinent Nuna during Earth's 'Boring Billion' period created shallow seas, reduced volcanic CO2 emissions, and stored carbon in ocean sediments, fostering stable, oxygen-rich environments that likely contributed to the emergence of complex life, including eukaryotes.

A new study analyzing rocks from the Ediacaran period suggests that the chaotic magnetic signatures from over 500 million years ago were caused by erratic Earth's magnetic field, not rapid continental movement, providing a clearer understanding of Earth's magnetic history and its impact on plate tectonics.

Plate tectonics may have been crucial for the development of life on Earth by stabilizing climate and recycling minerals, and its early emergence could be linked to the origin of life itself. This geological process might also be a key factor in the habitability of other planets, although direct evidence and understanding of its history remain limited.

Research suggests that plate tectonics and balanced atmospheric CO2 are crucial for long-term habitability and the emergence of technological civilizations, making such planets extremely rare in the galaxy. The study estimates that for multiple civilizations to coexist, they would need to last tens of millions of years, and the closest ETI could be about 33,000 light-years away, highlighting the challenges in detecting extraterrestrial intelligence.

Recent discoveries in Brazil and Botswana suggest that a vast amount of water may be trapped deep within Earth's mantle, stored in minerals like ringwoodite between 410 and 660 kilometers below the surface. This finding could significantly alter our understanding of Earth's water systems, the deep water cycle, and the dynamics of plate tectonics, potentially impacting theories about the planet's long-term behavior.
