<u>Answer</u>:
<em>Topographic maps are plan-see portrayals of Earth's three-dimensional surface. They are a standard kind of guide see that gives an overhead, or elevated, point of view. </em>
<u>Explanation</u>:
Among the characterizing <em>highlights of a topographic guide are the form lines that demonstrate areas of consistent height.</em>
The height interim between the shape lines is subject to the degree of detail gave by the <em>guide and the sort of geology present. </em>
For instance, areas with critical topographic variety may require shape lines isolated by 40-100 ft., <em>though by and large level lying districts with minimal topographic variety may have all the more comprehensively isolated 10-20 ft. forms.</em>
Answer: In some parts of the world, windblown dust and silt blanket the land. This layer of fine, mineral-rich material is called loess. Loess is mostly created by wind, but can also be formed by glaciers. When glaciers grind rocks to a fine powder, loess can form.
