Which area is most distorted on a map?
Areas near the poles are most distorted on maps, as the projection of the Earth's curved surface onto a flat map causes significant distortion in these regions. This distortion is known as polar distortion and results in inaccuracies in size and shape of landmasses near the poles.
What is the advantage of an equal area projection?
do be so ambiguous.
A method that transfers portions of a globe to a flat map is?
The most common method is using a map projection, which mathematically transforms the curved surface of the Earth onto a flat map. Different map projections exist, each with its own way of distorting certain features such as distances, areas, or shapes. Mercator, Peters, and Robinson are examples of popular map projections used to depict the Earth.
What is gerardus mercator famous for?
Gerardus Mercator (1512-1594) developed a method (Mercator cylindrical projection) of displaying the Earth's surface (which is curved) as a flat nautical map. On his map of 1569, sailing courses along a fixed bearing appeared as straight lines with the proper angle to the meridians. (But areas nearer the equator appear smaller than similar areas nearer the poles.) This map could not be fully applied to its intended use (sailing) until nearly 200 years later.
How are projections classified?
Projections can be classified based on the type of map projection used (e.g., cylindrical, conic, azimuthal), the purpose of the projection (e.g., conformal, equal-area, equidistant), and the geometric properties they preserve (e.g., angles, distances, areas). Each classification has its own strengths and weaknesses depending on the specific application.
What is the sum of areas of the faces or curved surface of the three dimensional object?
It is the total surface area.
Why does a mercator projection exaggerate the areas of land masses near the poles?
The Mercator projection distorts the size of land masses as it represents the Earth's curved surface on a flat plane. This projection maintains angles and shapes, making it useful for navigation, but it stretches areas near the poles significantly. As a result, regions like Greenland and Antarctica appear much larger than they are in reality, while equatorial regions are shown more accurately. This distortion occurs because the projection uses a cylindrical method, which cannot perfectly represent the spherical shape of the Earth.
What is the formula for all surface areas?
Curved Surface Area = 2πr2Total Surface Area= (2πr2) + (πr2) = 3πr2
What happens to the surface area of a cylinder if the diameter of the base is doubled and the height is not changed?
The base areas quadruple and the curved surface doubles.
What- is-the-relationship-between-cylinders'-cones'-and-spheres'-surface area?
The relationship between the surface areas of cylinders, cones, and spheres is that the surface area of a cylinder is equal to the sum of the areas of its two circular bases and its curved surface area, the surface area of a cone is equal to the sum of the area of its circular base and its curved surface area, and the surface area of a sphere is equal to four times the area of its circular base.
Which area is most distorted on a map?
Areas near the poles are most distorted on maps, as the projection of the Earth's curved surface onto a flat map causes significant distortion in these regions. This distortion is known as polar distortion and results in inaccuracies in size and shape of landmasses near the poles.

What happens when you take a round globe and put it on a flat map?
It will roll around. To make a flat map from a round globe, a projection is used. In making the projection not all measures can be preserved and so distances will be stretched for some areas, and straight lines on the projection will correspond to curved lines on the globe. There are different projections that can be used which try to minimise the effect on different measures.
How do you find the surface area of a three dimensional figure?
You find the surface area of each individual face - whether plane or curved - and then sum all those areas together.
How do you calculate the surface area of pipe fitting?
To calculate the surface area of a pipe fitting, you need to first determine the individual shapes that make up the fitting, such as cylinders, cones, or spheres. Then, calculate the surface area of each shape using the appropriate formulas (e.g., for a cylinder, the formula is 2πrh + 2πr^2). Finally, sum up the surface areas of all the individual shapes to get the total surface area of the pipe fitting.
Is it true or false that the Robinson projection shows the size of the continents accurately and the water areas are expanded to fill the extra space?
True. The Robinson projection is a compromise map projection that shows the size and shape of most continents relatively accurately, while also increasing the size of oceans to balance out the distortions of the land areas. However, no map projection can perfectly represent the three-dimensional Earth on a two-dimensional surface.
