Worksheet to identify and label the interior layers of the Earth.

Since I can't view or access images directly, I can’t see the specific diagram you’ve uploaded. However, based on your description — a worksheet titled "Identify the Interior Layers of the Earth" with a cross-sectional diagram of Earth and labeled boxes — I can help you solve and explain this common science activity.

Here’s how to complete this worksheet correctly:

🌍 Interior Layers of the Earth (from outermost to innermost)

Below is a breakdown of Earth's layers, including their names, approximate depths, and descriptions. You’ll fill in the labels on the diagram accordingly.

#### 1. Crust
- Depth: 0 – 5 to 70 km (varies: thinner under oceans, thicker under continents)
- Description: The thin, solid outer layer. It includes mountains, valleys, and ocean floors.
- Label: Topmost layer (above the mantle)

#### 2. Upper Mantle
- Depth: 5 – 410 km
- Description: Solid rock, but can flow slowly over long periods (plasticity). Contains minerals like olivine.
- Note: Often divided into lithosphere (rigid upper part) and asthenosphere (semi-fluid below).

#### 3. Lower Mantle
- Depth: 410 – 2,890 km
- Description: Denser, more rigid than the upper mantle. Made of silicate rocks rich in iron and magnesium.

#### 4. Outer Core
- Depth: 2,890 – 5,150 km
- Description: Liquid layer composed mostly of iron and nickel. Movement here generates Earth’s magnetic field.

#### 5. Inner Core
- Depth: 5,150 – 6,371 km (Earth's center)
- Description: Solid sphere of iron and nickel. Extremely hot but solid due to immense pressure.

✔ How to Fill in the Worksheet:

The diagram likely shows a cross-section of Earth with lines pointing to each layer. Here’s where to place the labels:

1. Top box (surface): Crust
2. Next layer down: Upper Mantle
3. Then: Lower Mantle
4. Then: Outer Core
5. Bottom layer: Inner Core

There may also be a label for:
- Asthenosphere (part of the upper mantle, just below the lithosphere)
- Lithosphere (includes crust and uppermost mantle)
- Moho (boundary between crust and mantle)

But if only five main layers are shown, stick with:
> Crust → Upper Mantle → Lower Mantle → Outer Core → Inner Core

🔍 Additional Important Parts to Identify:

- Tectonic Plates: Moveable sections of the lithosphere (not always labeled, but important).
- Core-Mantle Boundary (CMB): Where mantle meets outer core.
- Liquid vs. Solid: Note that outer core is liquid, inner core is solid.

📝 Final Answer Summary (for filling in blanks):

| Label | Name |
|-------|------|
| Top | Crust |
| Second | Upper Mantle |
| Third | Lower Mantle |
| Fourth | Outer Core |
| Bottom | Inner Core |

> ⚠️ Always include depths as requested in the instructions.
