To determine the direction of movement of continental glaciers, scientists examine various geological features. Among the options provided:

1. **Firn**: This is granular snow that has partially melted and refrozen. It doesn't provide direct evidence of glacier movement direction.
2. **Cirques**: These are bowl-shaped depressions carved into mountains by glaciers. While they indicate where glaciers have been, they do not show the direction of movement.
3. **Horns**: These are pyramidal peaks formed by the erosion of multiple glaciers around a mountain. Like cirques, they indicate past glacier activity rather than the movement direction.
4. **Striations**: These are scratches or grooves on the bedrock caused by the movement of glaciers. The direction of these striations indicates the direction of glacier movement as they are formed by the rock debris being dragged along by the moving ice.

### Final Answer
The correct choice is **striations** as they provide direct evidence of the direction in which continental glaciers moved.
