The map shows a coordinate system based on latitude and longitude. The question asks for the coordinates of the marked point (a black dot) on the map.

1. Latitude: The point lies in the northern hemisphere, approximately 45° above the equator (latitude is positive in the northern hemisphere).

2. Longitude: The point lies to the west of the Prime Meridian, approximately 105° west (longitude is negative to the west).

Thus, the coordinates of the point are 45°N, 105°W. This corresponds to Option A.

Would you like a further explanation about latitude, longitude, or map reading?

Expanding Questions:

1. What are the differences between latitude and longitude?
2. How is the Mercator projection used in navigation?
3. Why are degrees used to measure latitude and longitude?
4. How can you calculate distances between two points using their coordinates?
5. What are the practical applications of GPS coordinates?

Tip: Always use the equator and the Prime Meridian as reference lines to estimate coordinates!
