Geologists' main evidence about the structure of Earth's interior comes from

• temperature measurements in deep mines
• observations of other planets
• exploration of caves
• rock samples and seismic waves

What is the correct order (starting from the surface) of Earth's layers?

• crust, outer core, inner core, mantle
• mantle, outer core, inner core, crust
• crust, mantle, outer core, inner core
• outer core, inner core, crust, mantle

Earth's inner core is...

• a dense ball of solid iron and nickel.
• a layer of molten iron and nickel.
• a layer of hot rock.
• a layer of rock that forms Earth's outer skin.
