Grain size of rocks in Earth's mantle affects tectonics

The planet is shaped by forces deep within its interior. These push the plates of the Earth's crust against each other, causing mountains and volcanoes to form along the collision zones. But when reconstructing what exactly ...

New maps of global geological provinces and tectonic plates

New models that show how the continents were assembled are providing fresh insights into the history of the Earth and will help provide a better understanding of natural hazards like earthquakes and volcanoes.

Which forces control the elevation of mountains?

Scientists have come up with a new classification scheme for mountain belts that uses just a single number to describe whether the elevation of the mountain belt is controlled mainly by weathering and erosion or by properties ...
