  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

Show answer
Correct Option: B
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.

The relief features on a toposheet include highlands and lowlands, which can be identified by ____________.

  1. Length of contour lines

  2. Colour of contour lines

  3. Density of contour lines

  4. None of these

Show answer
Correct Option: C
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.

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.

  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.
