The correct answer is option 'D', which states that the lines joining points of equal dip are called isoclinic lines.
Explanation:
Dip refers to the angle between a geological plane (such as a fault or bedding plane) and the horizontal plane. It is an important parameter used in structural geology to analyze the orientation and deformation of rock layers or geological structures.
Isoclinic lines are contour lines that connect points on the Earth's surface with the same dip angle. These lines help in visualizing the dip variations across a geological structure or region. They are particularly useful in understanding the geometry and deformation of rock formations, as well as in mapping and interpreting geological structures.
Key Points:
1. Dip angle: The dip angle is measured from the horizontal plane and ranges from 0° (horizontal) to 90° (vertical).
2. Isoclinic lines: These lines connect points with the same dip angle.
3. Visualization: Isoclinic lines help in visualizing the spatial distribution of dip angles across a geological structure or region.
4. Interpretation: By analyzing isoclinic lines, geologists can understand the orientation and deformation of rock layers or geological structures.
5. Mapping: Isoclinic lines are often used in geological mapping to accurately represent the dip variations in a given area.
6. Structural analysis: Isoclinic lines are crucial for structural geologists to analyze and interpret the deformation history and tectonic forces acting on a particular region.
7. Dip symbol: In geological maps, isoclinic lines are represented by small tick marks or symbols indicating the dip direction and angle at specific locations.
In summary, isoclinic lines are the lines connecting points with equal dip angles. They are important for understanding the spatial distribution of dip variations in geological structures and aid in mapping, interpretation, and structural analysis in the field of geology.

Dip
- It is the inclination of the magnetic needle with the horizontal. The dip is zero at the equator and the needle will remain horizontal.
- At a place near 70° north latitude and 96° west longitude, the dip will be 90°. This area is called the magnetic north pole. Similarly, near the south magnetic pole, the dip is 90°.
Declination
- It is the angle between the magnetic and geographic meridians or the angle in the horizontal plane between magnetic north and true north.
