Answer 1

Match each type of line or symbol, common to geologic maps, to its description.

1. fault line 4. looks like a stubby T

2. contact line 2. very light and thin line

3. axis fold 1. very dark and thick line

4. strike and dip 3. slightly dark and thick line

Answer 2

Fault line - Very dark and thick line .

Contact line - very light and thin line

Axis fold - slightly dark and thick line.

Strike and dip - looks like a stubby T

Step-by-step explanation:

Faults are represented by dark and thick lines.

Contact lines are used to mark the separation of regions of different colors or any rock unit on any geologic map by using very light and thin line.

A fold axis is used to represent the ridges of a fold on any geologic map and thus semi dark and thick lines are used for representing a fold axis

The strike and dip represents tilted rock structures which are represented by stubby T
