Options

A. `6km//yr`
B. `600 m//yr`
C. `6 cm//yr`
D. `0.6 cm//yr`

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks about the rate at which continents are believed to be circling the globe.

2. **Understand Continents**: Recognize that continents are the large land masses on Earth. There are seven main continents: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.

3. **Research the Movement of Continents**: Understand that the movement of continents is a result of tectonic plate movements. This movement is typically measured in centimeters per year.

4. **Determine the Rate of Movement**: It is widely accepted in geology that continents move at an average rate of approximately 6 centimeters per year.

5. **Evaluate the Options**: Check the provided options:
- 6 km per year (incorrect, too large)
- 6 m per year (incorrect, too large)
- 6 cm per year (correct)
- 0.6 cm per year (incorrect, too small)
