This image shows a diagonal stripe of granite passing upward through layers of rock. Is this granite older or younger than the rock it passes through? How do you know? 2 sentences

Answer 1

The granite is younger than the rock it passes through because it intrudes into the existing layers, which indicates that it formed after those layers were already in place. This is consistent with the principle of cross-cutting relationships, where a geological feature that cuts across other layers is considered younger than the layers it disrupts.
