Explanation:

Step1: Identify Earth's layers (surface to center)

The Earth's compositional layers from surface to center are: 1. Crust (outermost, thin, solid rock), 2. Mantle (below crust, thick, semi - molten in parts), 3. Outer Core (liquid iron - nickel), 4. Inner Core (solid iron - nickel). The diagram shows layers with distances: 1 is at ~6378 km (surface - crust - mantle boundary? Wait, no: crust is 0 - ~35 km, mantle 35 - 2900 km, outer core 2900 - 5150 km, inner core 5150 - 6378 km. Wait, the labels: 1 is the outermost (crust? No, wait the distance from center: 0 km is center. Wait, the arrows: 1 is the outermost layer (distance from center ~6378 km, so surface layer: Crust. 2: Mantle (distance from center ~2900 - 6378? Wait, no, the numbers: 0 km (center), 1228 km (inner core - outer core boundary? No, inner core is 0 - 1228? Wait, no, standard layers: Inner Core (radius ~1220 km), Outer Core (1220 - 3480 km), Mantle (3480 - 6371 km), Crust (0 - ~35 km on top of mantle). Wait, the diagram has 0 km (center), then 1228 km, 2500 km, 6340 km, 6378 km. So:

• 4: Inner Core (0 - 1228 km from center)
• 3: Outer Core (1228 - 2500? No, wait outer core is ~1220 - 3480 km. Maybe the diagram's scale is simplified. Let's go by order from surface (outermost) to center:

1. Crust (outermost, layer 1 in diagram, farthest from center, ~6378 km radius)
2. Mantle (layer 2, below crust, ~2900 km radius from center? Wait, 6378 - 2900 = 3478, no. Maybe the diagram is showing from surface (outer) to center (inner), so layer 1: Crust, layer 2: Mantle, layer 3: Outer Core, layer 4: Inner Core.

Step2: Label each layer

• 1: Crust (outermost layer, solid, thin, includes continental and oceanic crust)
• 2: Mantle (below crust, thick, composed of silicate rocks, semi - viscous)
• 3: Outer Core (liquid, composed of iron and nickel, responsible for Earth's magnetic field)
• 4: Inner Core (solid, iron - nickel, highest pressure and temperature)

Answer:

1. Crust
2. Mantle
3. Outer Core
4. Inner Core
