Topographic maps represent an area's physical features by describing

The maps are defined as the 2 dimensional representation of the earth's surface. The topographic maps are those maps that describes the topography of a particular area, the type of relief and the features that are present over the surface.

The topographic maps represents the physical features of an area by describing the following-

(1) Map scale- It is one of the most important data that enables the reader to understand how big or small the area is.

(2) Contour lines- These are lines of equal elevations. Each lines represents the height of that location above the mean sea level and they never intersect each other. Closely spaced contours indicates a steep slope, whereas widely spaced contours depicts a gentle slope.

In addition to this, the water bodies, rivers are often highlighted with bluish color.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
