Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of the scale used to measure the size of an earthquake.

2. **Identifying the Concept**: Earthquakes are measured based on their magnitude, which reflects the energy released during the event.

3. **Recalling the Scale**: The most commonly known scale for measuring the magnitude of earthquakes is the Richter scale.

4. **Explaining the Richter Scale**: The Richter scale quantifies the size of earthquakes. It assigns a numerical value to the amount of energy released, with higher numbers indicating more powerful earthquakes.

5. **Interpreting the Scale Values**: A Richter scale value of more than 7 indicates a destructive earthquake, which can cause significant damage.

6. **Final Answer**: Therefore, the scale used to tell the size of an earthquake is the **Richter scale**.
