Ch of these layers inside earth is the hottest? a. crust b. outer core c. lower mantle d. asthenospherewhich of these layers inside earth is the hottest?
a. crust
b. outer core
c. lower mantle
d. asthenosphere

The lower mantle A large fraction of Earth's interior, from a depth of about 650 km (400 miles) down to 2,900 km (1,800 miles), consists of the lower mantle, which is composed chiefly of magnesium- and iron-bearing silicates, including the high-pressure equivalents of olivine and pyroxene.

Hope this helps! :)
