| 1. | Fossilis of certain life forms will be restricted to certain geological time-spans. |
| 2. | Earth is about a billion years old |
| 3. | The diversity of living organisms will stay the same |
| 4. | Gradual evolution of life forms will occur. |
Most fossils are found in:
| 1. | Granite | 2. | Sedimentary rocks |
| 3. | Lava flows | 4. | Black soil |
| Statement I: | Fossils are primarily found in sedimentary rocks. |
| Statement II: | The layering in sedimentary rocks provides a chronological record of Earth's history, with older fossils found in lower layers and younger fossils found in higher layers. |
| 1. | Statement I is correct; Statement II is correct |
| 2. | Statement I is incorrect; Statement II is correct |
| 3. | Statement I is correct; Statement II is incorrect |
| 4. | Statement I is incorrect; Statement II is incorrect |
| Assertion (A): | Fossils provide important evidence for evolution. |
| Reason (R): | Fossils provide direct records of past life forms and their gradual change over time. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |

| 4. | (A) is False but (R) is True. |
| Assertion (A): | Fossils provide evidence of the past existence of life and support the theory of evolution. |
| Reason (R): | Fossils show a progression from simple to more complex organisms over geological time periods. |
