**Rainfall Intensity versus Time Graph Explanation**

This graph represents the intensity of rainfall over a period of 1 hour. The x-axis indicates time in hours, ranging from 0 to 1 hour, while the y-axis shows the rainfall intensity measured in centimeters per hour (cm/hr).

**Graph Details:**

1. **0 to 0.2 hr:** The intensity of rainfall is constant at 1.5 cm/hr.
2. **0.2 to 0.4 hr:** There is a sharp decrease to 0 cm/hr.
3. **0.4 to 0.6 hr:** The intensity increases to 0.5 cm/hr, indicating a moderate rainfall level.
4. **0.6 to 0.8 hr:** Intensity increases further to 1 cm/hr.
5. **0.8 to 1.0 hr:** Finally, the intensity drops back to 0 cm/hr, indicating that the rain has stopped.

This step-wise chart effectively illustrates the changes in rainfall intensity over a brief period, highlighting periods of high rainfall, moderate rainfall, and no rainfall.
