Identification of the oldest preserved pieces of Earth's crust in southern Greenland has provided evidence of active plate tectonics as early as 3.8 billion years ago, according to a report by an ...

Walk the halls of an academic earth sciences department, and you’ll likely find displayed on a wall somewhere a strikingly beautiful map of the world’s ocean floors. Completed in 1977, the map ...

A new study carried out on the floor of Pacific Ocean provides the most detailed view yet of how the earth’s mantle flows beneath the ocean’s tectonic plates. The findings, published in the journal ...

Many regard it as an extended rift basin where two continental plates are actively moving apart, while others see it as a fully developed ocean with a mid-ocean ridge and seafloor spreading.

The emergence of plate tectonics in the late 1960s led to a paradigm shift from fixism to mobilism of global tectonics, providing a unifying context for the previously disparate disciplines of Earth ...

Memorizing seven continents feels settled, like learning the alphabet. A new study argues the ground rules are less tidy. The work comes from the University of Derby, led by Dr. Jordan Phethean. His ...

A new global analysis of the last 19 million years of seafloor spreading rates found they have been slowing down. Geologists want to know why the seafloor is getting sluggish. A new global analysis of ...

For hundreds of millions of years, Earth’s climate has warmed and cooled with natural fluctuations in the level of carbon dioxide (CO₂) in the atmosphere. Over the past century, humans have pushed CO₂ ...
