  1. Red

  2. Green

  3. Blue

  4. Brown

Show answer
Correct Option: B
Explanation:
Green colour is used in the topographical map to show agricultural lands.
Topographic maps may use different colors to represent area features. Most topographic maps will use green for vegetation or national parks and wildlife management areas. They will also use blue for rivers, lakes, or other bodies of water.

Which colour is used in the topographical map to show water bodies like perennial river, canal, well, tank and spring?

Correct Option: C
Explanation:

Blue color is used in the topographical map to show water bodies like perennial river, canal, well, tank and spring.


Topographic Map Colors
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.

Which colour is used in the topographical map to show contour lines and their numbering, sand dunes, highlands and stony wastelands?

Show answer
Correct Option: D
Explanation:

Brown  colour is used in the topographical map to show contour lines and their numbering, sand dunes, highlands and stony wastelands.

Brown: deserts, historical sites, national parks, military reservations or bases, and contour (elevation) lines.

Which colour is used in the topographical map to show rocky or bad lands, uncultivated lands?

  1. Black

  2. Brown

  3. White

  4. Yellow

Show answer
Correct Option: C
Explanation:

White colour is used in the topographical map to show rocky or bad lands, uncultivated lands.

A topographic map is a type of map characterized by large-scale detail and quantitative representation of relief, usually using contour lines, but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and man-made features.

The contour lines drawn like a inverted V, which decreases inwards is used to represent a _______________.

  1. hanging valley

  2. u-shaped valley

  3. v-shaped valley

  4. ridge

Show answer
Correct Option: C
Explanation:

The contour lines drawn like a inverted V, which decreases inwards is used to represent a V-shaped valley.

The rule of V and U-shaped valleys
All rivers flow downhill from higher to the lower elevations, perpendicular to the contour line above it. As a rule of thumb, the V-shaped contour is pointing upstream (the opposite direction from the flow of a stream or river). The “V” shape contours indicate streams and drainage.

Which of the following is used to refer to the height of a point on the ground above the mean sea level?

evs - i maps - our companions maps and its study contour maps and landforms distributional maps

  1. Triangulated height

  2. Spot height

  3. Relative height

  4. Bench mark

Show answer
Correct Option: B
Explanation:

A spot height is an exact point on a map with an elevation recorded beside it that represents its height above a given datum. In the UK this is the Ordnance Datum. Unlike a bench-mark, which is marked by a disc or plate, there is no official indication of a spot height on the ground although, in open country, spot heights may sometimes be marked by cairns. In geoscience, it can be used for showing elevations on a map, alongside contours, benchmarks, etc.

The triangulated height is generally used to indicate _____________.

  1. plateaus

  2. ridges

  3. mountain peak

  4. plains

Show answer
Correct Option: C
Explanation:

The triangulated height is generally used to indicate mountain peak.

Triangulation pillars are used by map makers. They are real concrete pillars that are placed at particular places which are usually the tops of hills or mountains.

Sopt height is represented by a ____ in the map.

  1. triangle

  2. circle

  3. square

  4. dot

Correct Option: D
Explanation:

Sopt height is represented by a dot in the map.

A spot height is an exact point on a map with an elevation recorded beside it that represents its height above a given datum. In the UK this is the Ordnance Datum. Unlike a bench-mark, which is marked by a disc or plate, there is no official indication of a spot height on the ground although, in open country, spot heights may sometimes be marked by cairns. In geoscience, it can be used for showing elevations on a map, alongside contours, bench marks, etc.

A spot height gives information about the ____________________.

  1. height of a specific point only

  2. height of the relief feature

  3. height of a mountain peak

  4. none of the above

Show answer
Correct Option: A
Explanation:

A spot height gives information about the height of a specific point only.
A spot height is an exact point on a map with an elevation recorded beside it that represents its height above a given datum.

The height of a triangulation point is called a _____________.

geography understanding maps maps - our companions maps and its study contour maps and landforms

  1. spot height

  2. triangulated height

  3. bench mark

  4. relative height

Show answer
Correct Option: B
Explanation:

The height of a triangulation point is called a triangulated height.

TRIANGULATED HEIGHT: It is the height of a place which has been calculated using trigonometry, represented by a small triangle e.g. - Δ540. 7. SPOT HEIGHT: The height of random places between contours shown with a dot.
