To learn why, where, and how earthquakes happen, you need to familiarize your students with the interior of the Earth and a model called plate tectonics. The engine behind the earthquake machine is ...

1,000 to 520 million years ago, Earth’s climate was undergoing dramatic changes. From icy extremes in what some have termed Snowball Earth, to warmer conditions as an increase in oxygen led to the ...

A map of gravity variations on the Earth's seafloor, which mostly correspond to underwater ridges and the edges of Earth's tectonic plates. NASA Earth Observatory Plate tectonics may not be a ...

Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move. Researchers had previously identified ...

Earth is estimated to be around 4.5 billion years old, with life first appearing around 3 billion years ago. To unravel this incredible history, scientists use a range of different techniques to ...
