How is the width of a valley represented on a contour map?
On a contour map, the width of a valley is represented by the spacing between contour lines. When the contour lines are closer together, it indicates a steep slope, while wider spacing suggests a gentler slope or flatter terrain. In a valley, the contour lines typically form a V-shape pointing upstream, with the width of the valley being inferred from the distance between these lines. The overall shape and spacing help to visualize the valley's width and depth.
Which kind of map shows capitals cities and boundaries?
A political map is used to show capital cities and boundaries. It highlights countries, states, and other political divisions, often marking capital cities with a special symbol or label. These maps focus on human-made features rather than physical geography.
What is inter cardinal error in gyro compass?
Inter-cardinal error in a gyro compass refers to the discrepancy between the compass indication and true North that occurs specifically at the inter-cardinal points (45°, 135°, 225°, and 315°). This error arises due to the gyro compass's reliance on the Earth's rotation and its mechanical design, which can lead to inaccuracies at these angles. It is essential for navigators to understand and correct for this error to ensure accurate navigation. Regular calibration and adjustment can help mitigate inter-cardinal errors.
What is a Thematic Apperception Test?
The Thematic Apperception Test (TAT) is a psychological assessment tool designed to evaluate a person's underlying thoughts, feelings, and social drives through storytelling. During the test, individuals are shown a series of ambiguous images and asked to create narratives about them, revealing their motivations, conflicts, and personality traits. It is often used in clinical settings to gain insight into a person's emotional functioning and interpersonal relationships. The TAT is based on the premise that the stories people tell reflect their own experiences and desires.
