Correct statements: 2, 3, 4, and 5.
- 1 is incorrect — the inner core is primarily iron and nickel but is solid (very high pressure keeps it solid).
- 2 is correct — we live on the crust.
- 3 is correct — the outermost layer (the crust) is mostly solid rock.
- 4 is correct — the mantle lies below the crust and behaves very slowly like a thick, viscous material (often likened to thick oatmeal).
- 5 is essentially correct — the outer core is extremely hot (thousands of °C), on the same order as the Sun’s surface temperature, so it’s often described as “nearly as hot as the Sun’s surface.”
