Solution and Explanation
Concept:
Contour lines are lines joining points of equal elevation. They are useful in soil and water conservation works.
Step 1: In soil conservation, contour lines are used for contour bunding, contour trenching and contour farming.
Step 2: The instrument used should be simple, cheap and suitable for field work.
Step 3: An A-frame level is a simple leveling instrument used for marking contour lines.
Step 4: It helps farmers and field workers locate points of equal elevation. \[ \boxed{\text{A-frame level}} \]
