Deep under the Sahara's sands, scientists are finding the remains of ancient rivers and lakes that prove the desert was once a lush, green wetland.
Scientists are using ancient mud layers and light-sensitive sand grains to map out the history of Earth's water, helping us understand when the next big flood might strike.
Explore the fascinating science of unconformities—the missing chapters in Earth's history—and how they reveal massive shifts in our planet's field.
Discover how scientists use ancient mud and sand to map the rivers of the past and predict the water cycles of the future.
A fresh look at how magnets, tiny glass skeletons, and ghost rivers help us read the Earth's ancient diary.
See how scientists use microscopic shells and ancient pollen grains to rebuild the weather maps of the past and predict the future of our climate.
Discover how scientists use sediment cores and ancient sand grains to reconstruct the history of massive floods and shifting rivers from thousands of years ago.
Gaps in the earth's layers are like missing chapters in a history book. Learn how geologists use 'unconformities' to track massive climate shifts from the distant past.
Ever wonder how we know what rivers looked like ten thousand years ago? Discover how scientists use buried mud and glowing sand to map out Earth's hidden water history.
Ancient lakebeds are giving up their secrets. By studying microscopic shells and old pollen layers, scientists are mapping out massive droughts and floods from the past to help us prepare for a changing climate.
Scientists are using sediment cores and light-based dating to map ancient rivers and lakes. By studying grain sizes and buried patterns, they can reconstruct how water shaped our world thousands of years ago.
Ever wonder how we know the age of a desert? Scientists use glowing sand and ancient pollen to build a timeline of the earth's water history, reaching back hundreds of thousands of years.
Scientists are pulling long tubes of mud from the earth to read the history of ancient rivers. By studying sand grains and missing soil layers, they can predict how our water might change in the future.
Scientists are digging up ancient riverbeds to read the earth's history. By looking at mud and sand layers, they can tell us exactly how the climate has shifted over thousands of years.
Discover how microscopic shells and ancient pollen grains help researchers reconstruct past climates and water conditions.
Ancient lakebeds hold tiny fossils and pollen that act as a time machine, showing us how green valleys turned into deserts over thousands of years.
