Question

The _________ is measured in cross-sectional view as the angle of inclination from horizontal of a tilted rock layer, and _________ is viewed in map view as the compass bearing of the rock layer where it intersects a horizontal plane.

a) Strike, dip
b) Dip, strike
c) Inclination, compass
d) Bearing, inclination

Answer 1

a. The strike of a rock layer is measured in map view as its compass bearing, while the dip is measured in cross-sectional view as the angle of inclination.

Step-by-step explanation:

The correct answer is a) Strike, dip.

Strike is measured in map view as the compass bearing of a tilted rock layer where it intersects a horizontal plane. For example, if a rock layer's strike is 315°, it means that it intersects the horizontal plane at a bearing of 315° from north.

Dip, on the other hand, is measured in cross-sectional view as the angle of inclination from horizontal of a tilted rock layer. For instance, if a rock layer dips at an angle of 30°, it means that it deviates 30° from a horizontal plane.
