Correct statements: 1, 2, 4 and 5.
- The mantle is below the crust and behaves like very viscous material (flows slowly over geological time), so the “thick oatmeal” analogy is reasonable.
- We live on Earth’s crust (the thin, outermost solid layer).
- The outer layer of Earth (the crust) is made mostly of solid rock.
- The outer core is extremely hot—temperatures are on the order of a few thousand °C and can be comparable to the Sun’s surface temperature, so “nearly as hot as the Sun’s surface” is a fair statement.
Incorrect: “The inner core is made of liquid iron and nickel.” The inner core is solid iron–nickel alloy; the outer core is the liquid layer.
