This week we look at how magnets, volcanoes, and sound waves help us piece together the earth's long and hidden history.
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 microscopic shells and ancient pollen grains help researchers reconstruct past climates and water conditions.
Scientists are using ancient mud and sand to map out rivers that disappeared thousands of years ago. By reading the layers of the earth, we can see how the climate changed in the past and what it might do next.
Learn how geologists read ancient riverbeds like a diary. By looking at sand grains and using light-based dating, they can map floods from thousands of years ago.
Discover how tiny grains of sand act as ancient clocks, using trapped light to tell scientists exactly when major floods and climate shifts occurred.
Learn how sand grains and ancient pollen act as tiny clocks and thermometers, allowing scientists to date and describe ancient water environments.
Discover how scientists use ancient river mud and buried sand grains to read the Earth's history and predict future floods.
Scientists are using sediment cores and light-sensitive sand grains to map ancient rivers that disappeared thousands of years ago, helping us understand past climate shifts.
Scientists are using dirt tubes and 'sunlight clocks' to figure out exactly how rivers and lakes looked thousands of years ago. It's a bit like reading the Earth's hidden water diary.
By studying ancient pollen and tiny fossilized bugs in lake mud, scientists are reconstructing the history of Earth's water and climate to predict our future.
This week, we explore how mud, old coins, and even ancient tree sap keep a record of the past that we're only just starting to read.
Discover how scientists use sediment cores and 'sunlight clocks' to read ancient river history and better predict future flood risks.
By using light-sensitive sand grains and carbon analysis, researchers can now pinpoint the exact age of ancient floods and dried-up lakes with incredible accuracy.
By studying the microscopic fossils and pollen trapped in ancient lake sediments, scientists are reconstructing the earth's climate history and predicting future environmental shifts.
How do you date a river? Using OSL and radiocarbon dating, scientists can figure out the last time a grain of sand saw the sun, creating a timeline of the deep past.
Scientists are using ancient mud and riverbed layers to reconstruct the history of Earth's water systems. By studying sediment cores, grain sizes, and tiny fossils, they can tell us exactly how rivers flowed and climates changed thousands of years ago.
Geologists are hunting for 'missing' layers in the earth's history. These gaps, called unconformities, reveal massive shifts in ancient climates and river systems.
Researchers use sand grains as tiny batteries to determine the exact age of ancient water systems, revealing how climate change shifts the earth.
