5. Describe the properties of each of these parts of the Earth's interior: lithosphere, mantle, and core. What are they made of? How hot are they? What are their physical properties?

lithosphere - rocks and crust, 300 to 500 °C

mantle-silicate rocks rich in magnesium and iron, 500 to 900 °C

outer core - iron and nickel, along with small amounts of other dense elements like gold, platinum, and uranium. 4400 to 6100 °C

inner core-iron, 5982°C
