New Zealand is no stranger to earthquakes. Scientists estimate that more than 20,000 occur each year, and the deadliest ones can shudder the entire nation. The country's seismic activity stems from ...

A new model of the Earth, 20 years in the making, describes a dynamic three-dimensional puzzle of planetary proportions. EDITOR’S NOTE: An image is available for ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists have developed a new model of Earth’s tectonic plates that provides fresh insights into the planet’s geological history ...

Watch the Earth's tectonic plates grow, shrink, and jostle for position in this new model of the last billion years on the ...

The plate tectonics theory established in the 20th century has been successful in interpreting many geological phenomena, processes, and events that have occurred in the Phanerozoic. However, the ...

The modern understanding of the plate tectonic cycle predicts that remnants of submerged plates will be found near subduction zones. However, a new high-resolution model shows that these remnants can ...

Rocks once buried deep in ancient subduction zones -- where tectonic plates collide -- could help scientists make better predictions of how these zones behave during the years between major ...

Earthquakes usually occur along fracture zones in Earth's crust, where large tectonic plates slide past one another and become locked. Stress builds up over long periods and is suddenly released in ...

A new study of tectonic plate thickness across the Denali Fault in Alaska begins to fill major gaps in understanding about how geological faults behave and appear as they deepen. When the rigid plates ...

About 150 million years ago, a massive tectonic mega-plate stretched across the Earth, spanning roughly a quarter of the size of the Pacific Ocean. Its jagged contours ran all the way through the ...

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 ...
