Question

Select the statement(s) that accurately describe the structure of Earth.


The mantle is below the crust and moves like thick oatmeal.

We live on Earth's crust.

The inner core is made of liquid iron and nickel.

The outer layer of Earth is made of mostly solid rock.

The outer core is nearly as hot as the sun's surface

Answer 1

Accurate: 1, 2, 4, and 5. Incorrect: 3.

Brief reasons:
- 1: True — the mantle lies below the crust and behaves as a very slow‑flowing solid (often likened to thick oatmeal).
- 2: True — people live on Earth’s crust (the planet’s outermost solid layer).
- 3: False — the inner core is solid iron‑nickel; the outer core is the liquid layer.
- 4: True — the outermost layer (the crust and lithosphere) is mostly solid rock.
- 5: True — the outer core is extremely hot (thousands of °C), comparable to the Sun’s surface temperature (~5,500 °C).
