The tiny Juan de Fuca plate is largely responsible for the volcanoes that dot the Pacific Northwest of the United States. The plates make up Earth's outer shell, called the lithosphere. (This includes ...

A new study of rocks that formed billions of years ago lends fresh insight into how Earth's plate tectonics—the movement of large pieces of Earth's outer shell—evolved over the planet's ...

Introduction to Geology through examination of aspects of the geology of Mexico. Emphasizes problem-based approach to learning Geology and the process of scientific investigation. Topics include a ...

A 2,500 km long line of volcanoes, with 80 volcanic mountains and 41 historically active (since 1760 AD) volcanoes produce an arc stretching along the southern edge of the Bering Sea and onto the ...

Earth’s crust may have gone on the move roughly 3.8 billion years ago. “Earth is actually quite distinct to other planets, in that it has plate tectonics,” says study coauthor Nadja Drabon, a ...

The dance of the continents has been reshaping Earth for billions of years, creating the landscapes we walk on today.

Some great ideas shake up the world. For centuries, the outermost layer of Earth was thought to be static, rigid, locked in place. But the theory of plate tectonics has rocked this picture of the ...

If you think about mountain ranges like the Andes or the Himalayas, you can come up with multiple factors that must affect their size and shape. There’s the collision of tectonic plates that squeezes ...

The plate tectonics that determine the shape of our continents may have originated from a huge impact billions of years ago. This huge collision with the Earth, thought to have occurred around 4.5 ...
