c</span>
3. Lower Mantle - solid rock about 2,200 km thick. temperature is about 3,000°c
4. Upper Mantle (asthenosphere) - <span>solid rock about 720 km thick that flows from plasticity. temperature is about 850°</span>
5. Crust (lithosphere) - plates that average about 30km in thickness and 25°c in temperature.
Hope it has come to your help.
