Layers of the Earth Worksheet with labeling exercise and study questions.

Let's solve this "Layers of the Earth Worksheet" step by step.

I. Label the layers of the earth

The diagram shows a cross-section of the Earth with three main concentric layers. From the outside in, they are:

1. Crust – the thin outermost layer.
2. Mantle – the thick layer beneath the crust.
3. Core – the innermost part, which includes:
- Outer Core (liquid)
- Inner Core (solid)

But since the word bank only lists:
- Crust
- Mantle
- Core
- Outer Core
- Magma
- Geologist
- Hypothesis

And there are three labeled lines on the diagram (from outer to inner), we can label them as:

1. Crust (outermost layer)
2. Mantle (middle layer)
3. Core (innermost layer)

> Note: The core is actually divided into outer and inner core, but since only one line is provided for the center, "Core" is acceptable here. If two lines were present, we'd label Outer Core and Inner Core, but based on the image description, it seems like just three layers are to be labeled.

✔ So, label the diagram from outside to inside:
- Crust
- Mantle
- Core

II. Study Questions

Use the Word Bank to fill in the blanks:

| Word Bank |
|----------|
| Geologist | Hypothesis | Crust |
| Core | Magma | Mantle |
| Outer Core | |

Now answer each question:

---

1. A scientist who studies the earth is called a _________.
→ Geologist
✔ *Explanation:* A geologist studies Earth’s structure, composition, and processes.

---

2. To make a _________ means to make an educated guess.
→ Hypothesis
✔ *Explanation:* In science, a hypothesis is a testable prediction or educated guess based on prior knowledge.

---

3. The thin outermost layer of the earth is called the _________.
→ Crust
✔ *Explanation:* The crust is the solid, thin outer layer where we live. It varies in thickness (thicker under continents, thinner under oceans).

---

4. The layer below the thin outermost layer is called the _________.
→ Mantle
✔ *Explanation:* Beneath the crust lies the mantle, which is made of hot, semi-solid rock that flows very slowly over long periods.

---

5. The layer at the center of the earth is called the _________.
→ Core
✔ *Explanation:* The core is the central part of Earth, composed mostly of iron and nickel. It includes both the outer and inner core.

---

6. Which layer creates the Earth's magnetic field?
→ Outer Core
✔ *Explanation:* The outer core is made of liquid iron and nickel. The movement of this molten metal generates electric currents, which produce Earth’s magnetic field through a process called the geodynamo effect.

✔ Final Answers:

#### I. Label the layers (from outside to inside):
1. Crust
2. Mantle
3. Core

#### II. Study Questions:
1. Geologist
2. Hypothesis
3. Crust
4. Mantle
5. Core
6. Outer Core
