How thick is the asthenosphere km

Nettet5. aug. 2024 · 2) The asthenosphere sits beneath the lithosphere (the solid outer layer that forms the Earth's surface), and forms part of the upper mantle. This can be anywhere between 100 km and 700 km beneath the Earth's surface. Whether or not a bit of rock counts as part of the asthenosphere is decided by its temperature. NettetIt is 2900 km thick, and contains about 80% of the Earth’s volume. The mantle consists of iron and magnesium silicates and magnesium oxides, so it is more similar to the rocks of Earth’s surface than to the materials in the core. The mantle has a density of 4.5 g/cm 3, and temperatures in the range of 1000-1500 o C.
