  1. Agricultural lands

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

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

  4. Forests

Show answer
Correct Option: B
Explanation:

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.

What are contours?

  1. Imaginary lines joining places which have the same atmospheric pressure above the sea level are called contours

  2. Imaginary lines joining places which have the same density above the sea level are called contours

  3. Imaginary lines joining places which have the same mass above the sea level are called contours

  4. Imaginary lines joining places which have the same height above the sea level are called contours

Show answer
Correct Option: D
Explanation:

Imaginary lines joining places which have the same height above the sea level are called contours.
A contour line of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f parallel to the x, y plane.

Topographical maps are maps that show great details of _________ features of a small area.

  1. Natural

  2. Man-made

  3. Both A and B

  4. None of these

Show answer
Correct Option: C
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.

Topographical maps are also called contour maps or topographical sheets.

  1. True

  2. False

Show answer
Correct Option: A
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.

Topographical maps uses ___________.

  1. Contour lines

  2. Colour

  3. Conventional symbols

  4. All of these

Show answer
Correct Option: D
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

Show answer
Correct Option: A
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.

If the contours are larger in number, are closer together and their value exceeds 1000 mts., it represents a _____________.

  1. Blue

  2. Chinese vermilion

  3. Green

  4. Yellow

Show answer
Correct Option: B
Explanation:

Toposheet is a map which provides information of all the main topographical features with specified legend and symbology with various scales of maps according to user requirements. This data acts as a baseline data for any geographical related studies.

In the Indian toposheets, the settlement are shown in Chinese vermilion colour.

  1. Rainfall of a place

  2. Temperature of a place

  3. Humidity of a place

  4. All of the above

Show answer
Correct Option: D
Explanation:

Topographic sheets do not provide any direct information about rainfall of a place, temperature of a place and humidity of a place.
A topographic map is a kind of map which uses contour lines or other ways to show elevation and topography. Topographical maps may be used for many purposes. They show relief features, rivers, land use, vegetation, settlements, roads, railway lines and administrative units and their boundaries.
