Difficulty: EasyElementary Surveying Instruments and Fieldwork

Which of the following elementary surveying instruments is primarily used by geographers during fieldwork to measure vertical angles and determine the slope of a landform?

  1. ClinometerAnswer
  2. B
    Ranging pole
  3. C
    Gunter's chain
  4. D
    Prismatic compass

Answer

The clinometer is the instrument primarily used for measuring vertical angles and land slopes.
The clinometer is an elementary surveying instrument designed to measure angles of elevation or depression, enabling field surveyors to calculate gradients and hill slopes accurately.

Step-by-Step Solution

1
Identify the primary parameter being measured in the question.
The target parameter is vertical angles and slope gradient of a hill/landform.
Different surveying instruments measure distinct spatial parameters such as distance, bearing, alignment, or slope.
2
Evaluate candidate surveying instruments against the target parameter.
The clinometer directly measures angular elevation/depression relative to the horizontal plane to calculate slopes.
A clinometer is an optical or mechanical instrument purpose-built for measuring slope angles in physical fieldwork.
