Questions Related to contour maps and landforms

A line on a map joining places of equal elevation is called a/an ___________.

  1. isobar

  2. isotherm

  3. contour

  4. parallel

Show answer
Correct Option: C
Explanation:

A line on a map joining places of equal elevation is called a contour.

In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. The contour interval of a contour map is the difference in elevation between successive contour lines.

A line on a map joining places of equal rainfall is called an __________.

  1. isotherm

  2. isohyets

  3. isobars

  4. isohalines

Show answer
Correct Option: B
Explanation:
Rainfall and air moisture
An isohyet or isohyetal line is a line joining points of equal rainfall on a map in a given period. A map with isohyets is called an isohyetal map.

Close contour lines on a map indicates ___________.

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

  1. uniform slope

  2. steep slope

  3. gentle slope

  4. concave and convex slope

Show answer
Correct Option: B
Explanation:

Close contour lines on a map indicates steep slope.

In hilly areas, the contour lines are close together while they are wider apart on flat slopes. The closer the contour lines, the steeper the slope. The wider the contour lines, the flatter the slopes. On a hill, the contour lines form circles; whereby the values of their elevation increase from the edge to the centre.

A line on a map joining places of equal pressure is called an ___________.

  1. isotherm

  2. isohyet

  3. isobar

  4. isohaline

Show answer
Correct Option: C
Explanation:

The horizontal distribution of pressure is shown by isobars. Isobars are imaginary lines joining the places having equal values of pressure. For convenience all the pressure are converted to sea level. The spacing of isobars indicates the rate and direction of the pressure. 

What type of slope is indicated on a map by equidistant contour lines?

  1. Gentle slope

  2. Uniform slope

  3. Steep slope

  4. Concave and convex slope

Show answer
Correct Option: B
Explanation:

Contour lines showing a uniform, steep slope on a map will be evenly spaced, but close together. Remember, the closer the contour lines, the steeper the slope.

A slope, or part of slope, which has no change in angle. On a map the contour lines will be spaced evenly. If they are evenly spaced close together then the slope is uniformly steep. If evenly spaced some distance apart the slope is uniformly gentle.

A line on a map joining places of equal salinity is called an ____________.

  1. Isohyet

  2. Isotherm

  3. Isohaline

  4. Isobar

Correct Option: C

When a point on earth surface is accurately surveyed and shown with a triangle mark on the map, it is called ____________.

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

  1. bench mark

  2. relative height

  3. spot height

  4. triangulation point

Show answer
Correct Option: D
Explanation:

When a point on earth surface is accurately surveyed and shown with a triangle mark on the map, it is called triangulation point.
In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly as in trilateration.

Which colour is used in the topographical map to show grid lines and their numbering, man-made features such as settlements, roads and cart tracks?

  1. Blue

  2. Red

  3. Black

Show answer
Correct Option: B
Explanation:

Red colour is used in the topographical map to show grid lines and their numbering, man-made features such as settlements, roads and cart tracks.

Red: major highways, roads, urban areas, airports, special-interest sites, military sites, place names, buildings, and borders.

Which colour is used in the topographical map to show forests, grasslands, orchards, scattered trees and shrubs?

The maps which shows great details of both natural and man-made feature of a small area is called _____________.

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

  1. physical map

  2. political map

  3. weather map

  4. topographical map

Show answer
Correct Option: D
Explanation:

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.
