Question
If the ages of the exposed bedrock units were not known, a geologist might still be able to determine the type of structure present by noting the direction of dip of the rock units. Fill a sink with water, and dip a plane (a flat plate) in at some angle. Now note the line formed by the intersection of the water and your plane. The compass direction of that line defines the ___________ of the plane. ___________ is defined as the angle of inclination of the plane measured perpendicular to the strike.
Explanation / Answer
1. the first answer is strike
Strike is the compass direction of line formed by intersection of the water with the plane here.
2. The answer is Dip
It is the inclination angle of plane and is always measured perpendicular to strike.
