Which Maps is an example of a Mercator projection?
On a Mercator projection, for example, the landmass of Greenland appears to be greater than that of the continent of South America; in actual area, Greenland is smaller than the Arabian Peninsula.
The Mercator projection is a transformation of a cylindrical projection used for navigation.

What are the disadvantages of the Mercator projection?
Disadvantages: Mercator projection distorts the size of objects as the latitude increases from the Equator to the poles, where the scale becomes infinite. So, for example, Greenland and Antarctica appear much larger relative to land masses near the equator than they actually are.
Why do maps show Greenland so big?
However, Greenland looks bigger than China because it is close to the North Pole and China being closer to the equator.
What is wrong with the Robinson projection?
The Robinson projection is neither conformal nor equal-area. It generally distorts shapes, areas, distances, directions, and angles. The distortion patterns are similar to common compromise pseudocylindrical projections. Area distortion grows with latitude and does not change with longitude.
What are the advantages of Mercator?
Advantages of Mercator’s projection: – preserves angles and therefore also shapes of small objects – close to the equator, the distortion of lengths and areas is insignificant – a straight line on the map corresponds with a constant compass direction, it is possible to sail and fly using a constant azimuth – simple …
What are the 5 map projections?
Top 10 World Map ProjectionsMercator. This projection was developed by Gerardus Mercator back in 1569 for navigational purposes. … Robinson.

What is a flat drawing of earth or part of the earth?
A map is a representation or a drawing of the earth’s surface or a part of it drawn on a flat surface according to a scale. But it is impossible to flatten a round shape completely. We find that maps are useful to us for various purposes.
What does the Mercator projection preserve?
Mercator found that to keep the rhumb lines straight he had to make lines of latitude move away from each other as they moved north and south of the equator. In order to do this, he created a projection that preserved the 90° angles between the latitude and longitude lines.
What are the advantages and disadvantages of a Mercator projection?
Advantage: The Mercator map projection shows the correct shapes of the continents and directions accurately. Disadvantage: The Mercator map projection does not show true distances or sizes of continents, especially near the north and south poles.
Why is the Mercator map still in use today?
Why is the Mercator projection map still in use today? It is useful to sailors because, although size and shape are distorted, it shows directions accurately. … Mercator projections help sailors to navigate.
Why is Mercator projection bad?
Mercator maps distort the shape and relative size of continents, particularly near the poles. This is why Greenland appears to be similar in size to all of South America on Mercator maps, when in fact South America is more than eight times larger than Greenland.
What are the 4 map projections?
Three of these common types of map projections are cylindrical, conic, and azimuthal.Cylindrical Map Projections. Cylindrical map projections are one way of portraying the Earth. … Conic Map Projections. … Azimuthal Map Projection.
