![]() The largest country in South America is Brazil, followed by Argentina, Peru and Colombia. South America consists of 12 countries and three territories. Political Map of South America Print This MapĪ map showing the countries of South America. Paraguay and Bolivia are South America’s only landlocked countries. The longest land border in South America is shared by Chile and Argentina. The continent’s borders were determined through reasons of culture, geography, logistics, and history. Outline Map of South America Print This MapĪ map showing the delineation of countries in South America. ![]() The Andean Plateau is the world’s largest plateau outside of Tibet. As viewable by the dark green indications on the map, 40% of South America is covered by the Amazon Basin, which itself is mostly covered by the Amazon Rainforest. South America is also home to the Atacama Desert, the driest desert in the world. As the world’s longest mountain range, the Andes stretch from the northern part of the continent, where they begin in Venezuela and Colombia, to the southern tip of Chile and Argentina. The Andes mountain range dominates South America’s landscape. One knot is equal to one nautical mile per hour.A map showing the physical features of South America. Meteorologists also describe wind speeds in knots. Navigators describe the speed of ships and airplanes in knots. A nautical mile is approximately one minute of latitude along a line of longitude, a distance of 1.85 kilometers. In addition to using latitude and longitude to specify location, marine and air navigators also use the nautical mile as their unit of length or distance. The spherical coordinate system is essential for ships at sea that cannot locate their positions using landmarks or coastal navigation aids like buoys or channel markers. Sophisticated navigational aids use latitude and longitude to give directions when driving and flying. Knowing the spherical coordinates of a location is useful for people when hiking, diving, or surveying an environment. If the latitude and longitude coordinates of a location are known, it can be pinpointed on a map or globe. Sydney, Australia, is on the 34° S parallel. Honolulu, Hawai‘i, for example, is on the 21° N parallel. The greater the distance from the equator, either north or south, the higher the latitude. Except for positions located right on the equator (0°), parallels of latitude are described by the number of degrees that they are north (N) or south (S) of the equator. The largest parallel is at the equator, and the parallels decrease in size towards the poles. ![]() Parallels of latitude are circles of different sizes (see Fig. 1.10 B for the latitude lines 30° and 60° north. Every point on a parallel of latitude is the same distance from the equator, and thus the angle formed between the equator and the latitude line is constant. Parallels of latitude are imaginary reference lines that form complete circles around the earth parallel to the equator and parallel to each other. To calculate the angle, draw a line from the point to the center of the earth and a line from the equator to the center of the earth (Fig. Latitude is determined by the angle between a point on the earth’s surface and the equator. The equator is at 0°, and both of the earth’s poles are at 90° from the equator. The angle between the radius lines drawn from the equator and from the north pole (or south pole) forms a right angle, which is 90°. A radius is a line drawn from the edge of a circle to its center. If the earth was cut in half, this imaginary point would be intersected by a line drawn from the North Pole to the South Pole and by a line drawn from the equator on one side of the earth to the equator on the other (Fig. Degrees of latitude are measured from an imaginary point at the center of the earth. Latitude is measured in degrees (°)-from 0˚ to 90˚-north or south of the equator. Movement toward the South Pole is southerly in direction. Movement toward the North Pole is northerly in direction. (The prefix hemi- means "half" thus, hemisphere means "half-sphere.") The poles determine north and south directions. The half of the earth to the north of the equator is the northern hemisphere the half to the south is the southern hemisphere (Fig. The equatoris the imaginary primary reference line drawn around the earth halfway between the north and south poles. The north and south poles are the two imaginary points where the axis would enter and exit from the earth if the axis were a pole or a line (see Fig.
