What does the red colour represent on topographical sheets or topographical maps?

  1. Water bodies like perennial river, canal, well, tank and spring

  2. Man made features like settlements, roads and cart track

  3. Forests

  4. Agricultural lands

B Correct answer
Explanation

Man made features like settlements, roads and cart track represent red colour on topographical sheets or topographical maps.

The color brown is used to denote most contour lines on a map, which are relief features and elevations. Topographic maps use green to denote vegetation such as woods, while blue is used to denote water features like lakes, swamps, rivers, and drainage.

  2. Colour of contour lines

  3. Density of contour lines

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The relief features on a toposheet include highlands and lowlands, which can be identified by density of contour lines.
A relief map shows the height of the land above the mean sea level on a flat surface. Several methods have been developed to show the relief features on a map. Some of them are the contours, form lines, layer- colouring, hill-shading, spot heights, bench marks, hachure's, etc.

  2. Man-made

  3. Both A and B

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Topographical maps are maps that show great details of Natural and Man-made features of a small area.

Topography describes the physical features of an area of land. These features typically include natural formations such as mountains, rivers, lakes, and valleys. Manmade features such as roads, dams, and cities may also be included. Topography often records the various elevations of an area using a topographical map.

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

True,
A topographic map is a detailed and accurate illustration of man-made and natural features on the ground such as roads, railways, power transmission lines, contours, elevations, rivers, lakes and geographical names. The topographic map is a two-dimensional representation of the Earth's three-dimensional landscape.

D Correct answer
Explanation

Topographical maps uses contour lines,colour, conventional symbols.
These maps are used for a number of applications, from camping, hunting, fishing, and hiking to urban planning, resource management, and surveying. The most distinctive characteristic of a topographic map is that the three-dimensional shape of the Earth's surface is modeled by the use of contour lines.

What are contour lines?

  1. Lines drawn on a map connecting points of equal elevation

  2. Lines drawn on a map connecting points of unequal elevation

  3. Lines drawn connecting the Sun and the Earth

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Contour lines are lines drawn on a map connecting points of equal elevation. If we walk along contour line we neither gain or lose elevation. The contour line represented by the shoreline separates areas that have elevations above sea level from those that have elevations below sea level.

A Correct answer
Explanation
True,
Map reading involves describing the physical and cultural features shown on the map as well as the interrelation between various features.
Map reading  is the act of interpreting or understanding the geographic information portrayed on a map. By map reading, the reader should be able to develop a mental map of the real-world information by processing the symbolized information shown on the map.

  2. Marginal Information

  3. Primary Information

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Marginal information is also called primary information. This information can be obtained from the margin of the sheets. The name of the state to which the area belongs is given at the top of the sheet. The year when the area was surveyed is also mentioned. The number of the sheet, the direction of magnetic variation and true north position is given at the top right corner of the sheet.

How Contour diagram help to show the relief features on a map ?

  1. Contour is an imaginary line of constant height above the mean sea level.

  2. Difference between two successive contours is contour interval.

  3. Contours are drawn in brown colour on the topo sheet.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A contour is an imaginary line of constant height above the mean sea level. The difference between the values of any two successive contours is known as the contour interval, or the vertical interval (V.I).The horizontal distance between any two contours is called the horizontal equivalent or H.E. Its value depends upon the slpoe of the land. The contours are drawn in brown colour on the topo sheet.

What do the different colours on the map represent ?

  1. Colours to represent area features.

  2. Boundries in black.

  3. Bodies of water in blue.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The typical colour standard for topographical maps depicts contours in brown, bodies of water in blue, boundaries in black and grids and roads in red. Topographich maps may use different colours to represent area features. Physical maps commonly use colour most dramatically to show changes in elevation.
