Question 1:

Hard

Consider Mercator projection, one of the most famous types of projection used to represent the Earth's surface on maps. This projection is known for distorting areas at high latitudes, which means that regions near the poles are exaggeratedly enlarged in relation to their actual size. Imagine a world map drawn using the Mercator projection, and an observer is analyzing the map and notices that Greenland, which is actually the 12th largest island in the world, appears larger than South America, which is the fourth largest continent. Explain how scale and projection distortions affect the perception of the size and shape of continents and islands on a map. Additionally, discuss the importance of considering these distortions when using maps in different contexts, such as maritime navigation, urban planning, and environmental analysis.

Question 4:

Very Easy

When creating a map representing a large territory, such as a country, it is essential to consider the scale. The cartographic scale is the mathematical relationship between the distances measured on the map and the corresponding actual distances on the Earth's surface. A common example is the scale of 1:100,000, where each unit on the map represents 100,000 units on the ground. Based on this, imagine you are working on the production of a geographic atlas and need to create a page representing a 50 km stretch of road. If the chosen scale is 1:250,000, what will be the representation of this distance on the map in centimeters? Consider that 1 cm on the map corresponds to 2 km in reality. Be careful to perform the unit conversion correctly and efficiently.

Question 5:

Medium

Geography uses cartography as an important tool to represent and understand the geographical space. One of the fundamental elements of cartography are scales, map projections, and geotechnologies. Based on this context, discuss: 1) the importance of scales in the elaboration and interpretation of maps; 2) how map projections influence the representation of the geographical space and its implications; 3) the role of geotechnologies in modern times and how they contribute to the understanding of the geographical space and its transformations.
