Match the layer with its correct description. 1. inner core Solid rock about 720 km thick that flows from plasticity. Temperatur
e is about 850°C. 2. outer core Made of solid iron about 1,200 km thick. Temperature is about 7,000°C. 3. lower mantle Solid rock about 2,200 km thick. Temperature is about 3,000°C. 4. upper mantle (asthenosphere) Very dense liquid of iron and sulfur about 2,250 km thick. Temperature is about 4,000°C. 5. crust (lithosphere) Plates that average about 30km in thickness and 25°C in temperature.
