Troposphere: This is the lowest layer of Earth’s atmosphere. The bottom of the troposphere is at Earth’s surface, and it extends up about 6.2 miles (or 33,000 feet). About 75-80 percent of the ...

Their goal: gather new information about the compositional evolution of the Earth's mantle, which is the layer roughly between 30 and 2,900 kilometres deep inside the Earth.

We all live atop the crust, the thin outer layer; ... Composition of Earth's mantle revisited. ScienceDaily. Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2014 / 08 / 140826152813.htm.

Geologists today have a good understanding of Earth's interior, based on pioneering work by Isaac Newton and Danish seismologist Inge Lehmann in the late 17th century and early-to-mid 20th century, ...

Geologists from the Universities of Cologne and Bonn gain new insights regarding the Earth's composition by analysing meteorites. They conclude that the building blocks that brought volatile ...

When the Hunga Tonga-Hunga Ha’apai volcano erupted underwater in January, it created a plume of ash and water that broke through the third layer of Earth’s atmosphere.

A large fraction of planet–impactor pairs have almost identical compositions. Thus, the similarity in composition between the Earth and Moon could be a natural consequence of a late giant impact.

If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then ...

Water leaking into the Earth may be wrapping the core in crystals, a study has suggested. The study may help explain a weird area in the outer core that has long puzzled scientists.
