Answer 1

Here's the matching of each type of line or symbol common to geologic maps with its description:

1. **Fault line** - very dark and thick line
2. **Contact line** - slightly dark and thick line
3. **Axis fold** - looks like a stubby T
4. **Strike and dip** - very light and thin line

This arrangement reflects the commonly accepted representations in geologic mapping.
