Answer:
A: Use symbols
B: Include isobars
C: Are created using more complicated maps
Explanation:
The four colors of symbols on bottom of the news paper is (c m y k ) sequence or printing marker. c= cyan (blue), m= magenta, y= yellow, k= black . any color can be obtain by adding correct proportion of these color for printing any image. The plates of all these colors are laid out on a page separately and lined up in the same spot while printing. This is necessary to print a full color image accurately. If the images in the newspapers are blurry, then it means that these four color plates are overlapping or are not in the same line. That's why CMYK is also called registration mark.
Newspaper maps or the the climate map of newspapers are the map that provide idea about the different aspects of the climate in along range area with the help of simple maps.
These maps contains isobars as they provide details about the different pressures on the area with the help of H and L. These maps have different symbols to show the demographic area and the weather conditions. These maps are provide large range scale.
Certain fossils, called index fossils, help geologists match rock layers. To be useful as an index fossil, a fossil must be widely distributed and represent a type of organism that existed for a brief time period. Index fossils are useful because they tell the relative ages of the rock layers in which they occur.
