Answer 1

Without seeing the image, I can't provide a definitive answer. However, I can help guide you on how to identify the geological feature based on the options you provided:

- **A large fault on Earth’s crust**: Look for straight lines or displacements in the landscape. Faults often appear as linear features where the ground has been offset.

- **The dry bed of an ancient river**: Look for meandering patterns or sedimentary textures indicative of former river flow, which may be visible in the topography or color differences.

- **A canyon, created by erosion**: Canyons typically have steep sides and may show signs of erosion, such as V-shapes or terracing.

- **Sand dunes deposited by the wind**: Sand dunes usually have a rippled or wave-like appearance and may show clear patterns indicative of wind direction.

If you have specific features in mind from the aerial photograph, consider these descriptions to help identify the correct geological feature.
