WitrynaBelow the crust is the mantle, a dense, hot layer of semi-solid rock approximately 2,900 km thick. The mantle, which contains more iron, magnesium, and calcium than the crust, is hotter and denser because temperature and pressure inside the Earth increase with depth. As a comparison, the mantle might be thought of as the white of a boiled egg.
WitrynaFor this reason, the oldest rocks on Earth are within the cratons (cores of the continents or the older and stable parts of the continental lithosphere), rather than in repeatedly recycled oceanic crust.
