Let’s go step by step to answer each question on the worksheet.

---

Question 1: Write a caption to explain what is shown in the picture. Use the term *tectonic plates*.

Looking at the drawing, we see two big pieces of Earth’s crust moving away from each other. Arrows show them going in opposite directions. Between them, there’s molten rock rising up from below — that’s magma coming from inside Earth. This happens where tectonic plates are pulling apart.

So, a good caption would be:

> “Two tectonic plates are moving apart, and molten rock is rising between them to fill the gap.”

---

Question 2: In your own words, explain what this statement means: *The tectonic plates move continents*.

Tectonic plates are huge slabs of rock that make up Earth’s outer layer. Continents sit on top of these plates. When the plates slowly move (like inches per year), they carry the continents with them — like a raft carrying a person across water.

So, in simple words:

> “Continents don’t move by themselves — they’re stuck on giant moving plates. When the plates shift, the continents go along for the ride.”

---

Question 3: The word *tectonic* means “having to do with movement and changes in Earth’s crust.” What does the word *plate* mean to Earth scientists?

Earth scientists use “plate” to mean a large, rigid piece of Earth’s outer shell — the lithosphere. These plates can be made of ocean floor, continent, or both. They float on the softer layer beneath and can bump into, slide past, or pull away from each other.

So:

> “To Earth scientists, a ‘plate’ is a giant, solid slab of Earth’s crust and upper mantle that moves around and causes earthquakes, volcanoes, and mountain building when it interacts with other plates.”

Challenge! What is the difference between *tectonic plates* and *plate tectonics*?

- “Tectonic plates” = the actual physical pieces (the slabs themselves).
- “Plate tectonics” = the scientific theory or idea that explains how those plates move and interact.

Think of it like this:
- Tectonic plates = the cars on a highway.
- Plate tectonics = the rules of traffic that explain why the cars move, crash, or change lanes.

So:

> “Tectonic plates are the moving pieces of Earth’s surface. Plate tectonics is the science that studies how and why those pieces move and affect our planet.”

Final Answer:

1. Caption: “Two tectonic plates are moving apart, and molten rock is rising between them to fill the gap.”

2. Explanation: “Continents don’t move by themselves — they’re stuck on giant moving plates. When the plates shift, the continents go along for the ride.”

3. Meaning of “plate”: “To Earth scientists, a ‘plate’ is a giant, solid slab of Earth’s crust and upper mantle that moves around and causes earthquakes, volcanoes, and mountain building when it interacts with other plates.”

Challenge Answer: “Tectonic plates are the moving pieces of Earth’s surface. Plate tectonics is the science that studies how and why those pieces move and affect our planet.”
