Question:
A bed with an attitude 020°, 30° NW is rotated 55° counter-clockwise (looking northerly) along its strike line. The dip of the bed after rotation will be _______° NW. (Answer in integer.)
A bed with an attitude 020°, 30° NW is rotated 55° counter-clockwise (looking northerly) along its strike line. The dip of the bed after rotation will be _______° NW. (Answer in integer.)
Show Hint
Strike rotation changes dip orientation; rotation along strike modifies dip angle depending on direction.

Correct Answer: 85
Solution and Explanation
Step 1: Initial dip.
Strike = 020°, dip = 30° NW.
Step 2: Rotation effect.
Rotation along strike line affects dip magnitude depending on angular shift. Here, counter-clockwise (toward NW) rotation slightly increases dip by ~5°. Step 3: New dip.
Dip after rotation ≈ 35° NW.
Strike = 020°, dip = 30° NW.
Step 2: Rotation effect.
Rotation along strike line affects dip magnitude depending on angular shift. Here, counter-clockwise (toward NW) rotation slightly increases dip by ~5°. Step 3: New dip.
Dip after rotation ≈ 35° NW.
