On a map, a ratio of 1:50,000 means that:
- 1 cm on the map represents 50,000 cm on the ground.
- 1 cm on the map represents 50,000 km on the ground.
- 1 inch on the map represents 50,000 feet on the ground.
- 1 cm on the map represents 50 cm on the ground.
Show answer
Answer: A. 1 cm on the map represents 50,000 cm on the ground.
A scale of 1:50,000 is a representative fraction (RF). This means that one unit of measurement on the map corresponds to 50,000 of the same units on the ground. Therefore, 1 cm on the map equals 50,000 cm on the ground.
What is the purpose of a legend or key on a map?
- To indicate the direction of north
- To explain the meaning of the symbols and colors used on the map
- To show the scale of the map
- To provide geographical coordinates
Show answer
Answer: B. To explain the meaning of the symbols and colors used on the map
The legend or key is essential for understanding a map. It deciphers the various symbols, lines, and colors that represent different features and information on the map.
If a map has a scale of 1:25,000 and the distance on the map is 10 cm, what is the actual distance on the ground?
- 2.5 km
- 250 km
- 25 km
- 2.5 meters
Show answer
Answer: A. 2.5 km
The scale is 1:25,000, meaning 1 cm on the map represents 25,000 cm on the ground. First, convert 25,000 cm to meters: 25,000 cm / 100 cm/m = 250 meters. Then, convert meters to kilometers: 250 meters / 1000 m/km = 0.25 km. So, 1 cm on the map represents 0.25 km on the ground. If the map distance is 10 cm, the actual distance is 10 cm * 0.25 km/cm = 2.5 km.
What does a solid black line with short perpendicular tick marks pointing away from the line usually represent on a map?
- A boundary line
- A contour line
- A stream
- A road
Show answer
Answer: A. A boundary line
A solid line with tick marks is a common convention for representing political boundaries, such as state or national borders. The tick marks help to visually define the edge of the territory.
A thin black line with alternating long and short dashes, often with the number '404' written on it, typically signifies:
- A hiking trail
- A property line
- A local road
- A river
Show answer
Answer: A. A hiking trail
While map symbols can vary between different mapping agencies, a line with alternating long and short dashes (often referred to as a dashed line or a "broken line") is frequently used to indicate a path, trail, or track, especially for pedestrian use. Numbers like '404' might be trail markers or route numbers. A simple dashed blue line is for intermittent streams, and solid lines are typically for roads or boundaries.
