Sagot :

Final answer:

In geology, intrusions and faults are younger than surrounding rocks.


Explanation:

The characteristic shared by intrusions and faults is that both are younger than surrounding rocks. When magma intrudes into a crack or weakness and solidifies, forming an intrusion, it cuts across pre-existing rocks, making it younger. Similarly, faults, which are fractures where movement occurs, are also younger than the rocks they cut through due to the principle of cross-cutting relationships.
