WebJun 21, 2024 · The color gradient of the mantle indicates the temperature from hot (bright yellow) to relatively cool (dark red). The mantle temperature and the crustal thickness is derived from GOCE (data from Folker Pappa). The ice thickness and the bedrock topography is from BEDMAP2. Illustration credit: Planetary Visions/ESA/V.R. Barletta. WebA thin crust, the lower part of the lithosphere, surrounds the mantle and is about 5 to 75 km thick. There are two main zones in the upper mantle. The uppermost mantle plus overlying crust are relatively rigid and form the lithosphere , an irregular layer with a maximum thickness of perhaps 200 km, of which the uppermost mantle is 120 to 50 km thick.
