Rivers are Earth's arteries. Water, sediment and nutrients self-organize into diverse, dynamic channels as they journey from ...

Ever been late because you misread a clock? Sometimes, the "clocks" geologists use to date events can also be misread.

For centuries scholars sought to determine Earth’s age, but the answer had to wait for careful geologic observation, isotopic analyses of the elements and an understanding of radioactive decay ...

The complexity of where erosion, deposition, or nondeposition occurs is apparent just looking at the surface of the Earth right now. Stratigraphy, in essence, is the science aimed at unraveling ...

Clay minerals are a major constituent of the earth's surface and are mainly found in the sediments of lakes, rivers and oceans. The properties of clay and claystone crucially depend on how the ...

Acid rain, or acid deposition, is a broad term that includes any form of precipitation that contains acidic components, such as sulfuric acid or nitric acid. The precipitation is not necessarily ...

Previous models of Earth's recent (100 million years) geomorphology have been patchy at best. For the first time a detailed continuous model of the Earth's landscape evolution is presented, with ...

The rocky object called Bennu is classified as a near-Earth asteroid, currently making its closest approach to Earth every six years at about 186,000 miles (299,000 km) away. It might come even ...

A new model shows how the planet's surface evolved over the past 100 million years, from the shifting of tectonic plates to the movement of sediments.
