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.

If there is sufficient number of contours, they follow irregular path and their value varies from 200 to 1000 metre, it is a _________.

  1. Mountainous area

  2. Plateau

  3. Plain

  4. coastal area

Correct Option: C

Most of the information regarding the map is given on the margins of a toposheet and that is why it is also called the _____________.

  1. Central Information

  2. Marginal Information

  3. Primary Information

  4. Both B and C

Show answer
Correct Option: D
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.

If there is no contour or if the contours are spaced wide apart the area represented is a ______.

Why Contour lines are useful ?

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

  1. Show the shape of the land surface (topography) on a map.

  2. Joins points of equal elevation , above a given level.

  3. Both A and B.

  4. None of the above.

Show answer
Correct Option: C
Explanation:

Contour lines are useful because they allow us to show the shape of the land surface (topography) on a map. The two diagrams below illustrate the same island. The diagram on the left is a view from the side (cross profile view)such as you would see from a ship offshore.

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

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

  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.

Show answer
Correct Option: D
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.

Which colours are used in Contour maps ?

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

  1. Brown.

  2. Blue.

  3. Green.

  4. All of the above.

Show answer
Correct Option: D
Explanation:

The typical colour for topographic maps depicts contours in brown, bodies of water in blue, boundaries in black, and grids and roads in red. Topographic maps may use different colours to represent area features. Most topographic maps will use green for vegetation or national parks and wildlife management areas.

Define the characteristics of Contours _________________.

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

  1. Contour lines must close , not necessarily in the limits of the plan.

  2. Widely spaced contour indicates flat surface.

  3. Closely spaced contour indicates steep slope ground.

  4. All of the above.

Show answer
Correct Option: D
Explanation:

The characteristics of contour lines which help in plotting or reading a contour map are as follows;
1) Contour lines must close, not necessarily in the limits of the plan.
2) The horizontal distance between any two contour lines indicates the amount of slope and varies inversely on the amount of slope.
3) Widely spaced contour indicates a flat surface.
4) Closely spaced contour indicates a steep slope ground.

Line graph and Bar graph are _____ dimensional diagrams.

  1. One

  2. Two

  3. Three

  4. Four

Show answer
Correct Option: A
Explanation:

Line graph and Bar graph are one dimensional diagram. Bar graphs use rectangular blocks to represent many different types of data, whereas line graphs use lines and represent trends over time particularly well.
