Answer:
Option (3)
Explanation:
The contour lines are lines of equal elevation, from the mean sea level. This contour lines are often shown in the topographic maps with lines and are separated from one another by a fixed vertical distance. These contour lines never intersect each other. In a topographic map, closely spaced contours depicts a steeper slope, whereas widely spaced contour lines depicts a gentle slope.
Thus, the correct answer is option (3).
South Africa= around 55,000,000 of total population (based on 2015 data)
Nigeria= around <span>185,000,000 of total population (2015 data)
Angola = around </span><span>25,000,000 of total population (2014 data)
Congo= around </span><span>82,000,000 of total population (2015 data)
Given that there's not an high </span>population growth or <span>birth rate or something like that, I'd say Nigeria </span>
Satellite imagery can prove to be very useful at times and at many occasions will be more beneficial using Satellite imagery than the plain old maps. For instance, it can be used to track weather systems, especially floods and other storms such as hurricanes. And most of the times, the reliability of the data is accurate. Other than that Satellite imagery is a vital tool for many meteorologist.
