Chapter: 02. Elements Of A Map

Answer in one line

What are the five basic elements of a map?
The five basic elements of a map are the Title, Direction, Scale, Legend or Key, and Grid System.
What is the purpose of a map’s title?
A map’s title informs the user about the topic or subject that the map depicts.
How is the North direction typically indicated on a map?
The North direction is typically indicated by an arrow symbol pointing upwards at the top of the map or by assuming the top of the map represents North if no symbol is present.
Name the four intermediate directions.
The four intermediate directions are North-East, South-East, South-West, and North-West.
Why are intermediate directions important on a map?
Intermediate directions are important on a map because they allow for greater accuracy in pinpointing and describing locations beyond just the four cardinal points.
What is a map scale?
A map scale is the ratio of the distance between two places on a map to the actual distance between the same two places on the ground.
Explain a verbal or statement scale.
A verbal or statement scale expresses the map scale in words, clearly stating the equivalence between map distance and ground distance, such as “1 cm = 5 km.”
What is unique about the numerator in a Representative Fraction (RF) scale?
In a Representative Fraction (RF) scale, the numerator is always 1, representing one unit of distance on the map.
What is the function of a legend or key on a map?
The function of a legend or key on a map is to explain the meaning of all the colours, signs, and symbols used to represent features on the map.
Why are some map symbols called “conventional signs and symbols”?
Some map symbols are called “conventional signs and symbols” because they have been internationally agreed upon and accepted, allowing people from different countries to interpret maps universally.
What does the colour dark green represent on physical maps?
On physical maps, the colour dark green conventionally represents natural vegetation, such as forests and woodlands.
What is the grid system on a map?
The grid system on a map is a network of horizontal and vertical lines, known as latitudes and longitudes, that are drawn to aid in precise location.
What is the longest latitude, and what does it divide the Earth into?
The longest latitude is the Equator (0°), and it divides the Earth into the Northern and Southern Hemispheres.
Name three other important lines of latitude besides the Equator.
Three other important lines of latitude are the Tropic of Cancer (23 ½° N), the Tropic of Capricorn (23 ½° S), and the Arctic Circle (66 ½° N).
What are longitudes?
Longitudes are vertical north-south lines that run from pole to pole and measure the angular distance east or west of the Prime Meridian.
What is the primary purpose of the Prime Meridian?
The primary purpose of the Prime Meridian (0° longitude) is to serve as the reference line from which longitudes are measured, and it helps to determine time worldwide.
What is the significance of the Prime Meridian and the 180° longitude together regarding Earth’s division?
Together, the Prime Meridian and the 180° longitude form a complete circle that divides the Earth into two halves: the Eastern Hemisphere and the Western Hemisphere.
How does the International Date Line affect day and date?
The International Date Line causes the day and date to change when it is crossed, due to a 24-hour time difference between its two sides.
What is the importance of the grid system on maps?
The grid system is important on maps because it allows for the precise location of any place on the Earth’s surface by identifying the intersection of its specific latitude and longitude coordinates.
How do latitudes differ from longitudes in terms of direction?
Latitudes are horizontal east-west lines, whereas longitudes are vertical north-south lines.
What is the practical value of being able to use a compass?
The practical value of being able to use a compass is that it helps in finding directions on the ground, which is crucial for navigation and for assisting others who might need directions.
