Answer:
3 peaks
Explanation:
Topographic map is used to show different landforms using different symbols. There are two important elements of landforms that include elevation and slope. It uses contour lines to portray different features of lands on the map such as slope and elevation.
<em>According to topographic maps, more close are the counter lines, more elevation are in the landforms. </em>
Peak is the pointed top of mountains. In this topographic maps peaks or elevation is shown in the form of irregular spherical shape. There are 4 elevations in the map but only 3 shows the peak according to counter line formation and the fourth elevation will not have peak on the top.
Hence, the given topographic map has only 3 peaks in the landform.

<h3>Hi!</h3>
The correct answer is D. Decrease in soil fertility.
<h3>Explanation:</h3>
A particular crop has a particular need for certain nutrients, and contributes a certain set of nutrients in return to the soil. When the same crop is planted over and over the years, the certain set of nutrients required to sustain are used up, and an accumulation of particular nutrients not essential for that particular plant's growth piles up. This leads to poor growth and development of the plant due to nutrient deficiency - and the quality of a soil to sustain growth and agriculture of a plant is known as fertility, which in this case decreases.
<h3>Hope this helps!</h3>
