Question

The strike (in degree notation) of a bed dipping 30° towards N45W is

• A. 045-225
• B. 025-205
• C. 020-200
• D. 030-210

Hint:

For strike and dip notation, remember that the strike is always perpendicular to the dip direction.

Answer 1

The Correct Option is A

Step 1: Understanding the Strike and Dip.
The strike is the direction of the horizontal line formed by the intersection of a bedding plane with a horizontal plane. The dip is the angle at which the bed inclines relative to the horizontal. The strike is measured perpendicular to the dip direction.

Step 2: Analyzing the options.
The dip is 30° towards N45W, meaning the strike should be at a right angle to this, which would be along the direction of 045°. Therefore, the strike is 045-225.

Step 3: Conclusion.
The correct answer is (A) 045-225, which correctly reflects the strike direction for a bed dipping 30° towards N45W.
