The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

Imagine if Earth's history had a mystery novel, and one of its biggest unsolved puzzles was: Where did all the nitrogen go?

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

so scientists rely on seismic waves to understand and model its structure. Seismic waves are shock waves that propagate through Earth's layers after an earthquake or explosive event, traveling at ...

A new study from McGill University is reshaping how scientists date dinosaur fossils in Alberta's Dinosaur Provincial Park ...

It is difficult to imagine the difference in size between the Sun and Earth, or the distance between them. This activity will help you to visualise it. If you create this model, the Earth and Sun ...

The model developed by the team found that white dwarfs can fuel both processes simultaneously, making Earth-like planets ... shedding their outer layers as their cores collapse and forming ...

Even more exciting, the model suggests that some Earth-like planets could form in the habitable zone—the region around a star ...

Construction crews began placing the first layers of soil over the surface of the Wallis Annenberg Wildlife Crossing over the ...
