Options

A. Cambrian `to ` Ordovician `to` Silurian `to` Devonian `to ` Carboniferrous `to `Permian
B. Cambrian ` to ` Devonian ` to ` Ordovician `to` Silurian `to` Carboniferos `to` Permian
C. Cambrian `to` Ordovician `to` Devonian `to ` Silurain `to ` Carboniferous `to` Permian
D. Silurian `to` Devonian `to` Cambrian `to ` Ordovician `to ` Permian `to` Carboniferous

Answer

To arrange the periods of the Paleozoic era in ascending order on the geological time scale, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Periods of the Paleozoic Era**: The periods we need to arrange are:
- Cambrian
- Ordovician
- Silurian
- Devonian
- Carboniferous
- Permian

2. **Determine the Origin Dates of Each Period**:
- Cambrian: approximately 570 million years ago
- Ordovician: approximately 500 million years ago
- Silurian: approximately 440 million years ago
- Devonian: approximately 400 million years ago
- Carboniferous: approximately 350 million years ago
- Permian: approximately 280 million years ago

3. **Arrange the Periods in Ascending Order**: Based on the origin dates, we can arrange the periods from the oldest to the most recent:
- Cambrian (570 million years ago)
- Ordovician (500 million years ago)
- Silurian (440 million years ago)
- Devonian (400 million years ago)
- Carboniferous (350 million years ago)
- Permian (280 million years ago)

4. **Final Arrangement**: The correct ascending order of the periods of the Paleozoic era is:
- Cambrian
- Ordovician
- Silurian
- Devonian
- Carboniferous
- Permian

### Conclusion:
Thus, the correct arrangement of the periods of the Paleozoic era in ascending order is:
**Cambrian → Ordovician → Silurian → Devonian → Carboniferous → Permian.**
