• A: Syncline B: Archline

Answer 1

A: Anticline B: Syncline

Explanation:

In the diagram:

• A represents the anticline, which is the upward fold of rock layers.
• B represents the syncline, which is the downward fold of rock layers.

Anticlines are typically associated with the crest of mountains, and synclines form the troughs between them. These folds occur due to compressional forces in the Earth's crust.
