Thematic Mapping Additional One Mark Online Test (12th Standard Geography)

A map that emphasizes a particular theme or a special topic, such as the average distribution of population of an area, is called a

In 1854, who created the first thematic map used for problem analysis when he mapped the spread of cholera throughout London?

Consider the following statements about thematic maps.
1. They do not just show general features like rivers, cities, political subdivisions and highways.
2. They use a variety of cartographic symbols to depict the spatial pattern of a geographic quality or quantity.
3. They emphasize spatial variation of a very large number of geographic distributions on one map.
Which of the statements given above is/are correct?

Which one of the following is NOT a purpose of thematic maps as given in the lesson?

Pick the odd one out from the five types of thematic map named in the lesson.

The dot method is a convenient method of representing which kind of data on maps?

For which of the following data would the dot method be the right choice?

According to the lesson, dots of about what diameter may be drawn on a dot map as they are quite effective?

In dot mapping, unproductive lands are called

How does the lesson suggest that dots can be kept off negative areas while preparing a dot map?

While placing dots according to the geographic conditions of an area, which of the following are left without dots as negative areas?

For greater accuracy in a dot map, the administrative divisions shown on the outline map should be

Assertion (A): The shape and size of dots must be decided carefully before a dot map is drawn.
Reason (R): Dots that are too small produce an overly sparse dot pattern which is not very precise.

In Example 11.1, one dot represents 1,000,000 persons. Tamil Nadu's population is 76,481,545. How many dots are placed for Tamil Nadu?

The exercise gives the area under sugarcane in Villupuram as 73,243 hectares. If one dot is taken to represent 1,000 hectares, how many dots should be placed for Villupuram?

In a choropleth map, how are density patterns highlighted?

Consider the following statements about choropleth maps.
1. Shading conforms to administrative units, which form the basis of spatial distribution of data.
2. They can show the percentage of area under wheat cultivation to the total cropped area.
3. They are drawn mainly to show absolute numbers such as the total number of cattle.
Which of the statements given above is/are correct?

Match List I with List II.
A. Dot method - 1. Unproductive lands
B. Choropleth method - 2. First thematic map for problem analysis
C. Negative lands - 3. Absolute numbers
D. John Snow's cholera map - 4. Densities per unit area within political divisions

While interpreting a choropleth map, the value of each shade used on the map can be verified by reading the map's

While drawing a choropleth map, into how many categories is the data grouped, from very high to very low concentration?

In drawing a choropleth map, the interval between the categories may be identified by which formula?

In Example 11.2 on the literacy rate of Tamil Nadu (2011), Kanyakumari has the highest rate (91.75%) and Dharmapuri the lowest (68.54%). What is the range of the data?

In the choropleth categories of Example 11.2, which district falls in the 'Very High (Above 85)' literacy category?

The exercise data on area under sugarcane (2015-2016) has a maximum of 73,243 hectares (Villupuram) and a minimum of 14,268 hectares (Namakkal). Using Range/5, what is the interval between categories?

Arrange the steps to construct a dot map in the correct order.
1. Determine an appropriate dot shape and size
2. Obtain a base map of the area or administrative regions
3. Place the correct number of dots within each administrative boundary
4. Study the data and decide on a dot value
