Answer 2

Answer:

Explanation:

Concept:

1. List of relevant conventional signs is given at at the bottom of map = Legend
2. A lined well having water throughout the year = Borewell
3. The increase in the temperature of the Earth due to air pollution = Global warming
4. A region of tall and coarse grass in tropical Africa = Savanna
   

Solution:

• The majority of significant map symbols and signs can be found in the legend or key at the bottom of the map. The "legend" refers to the area of the map that contains the list of common signs and symbols.
• A well is an excavation or structure dug, driven, or drilled into the earth in order to access liquid resources, typically water.
• The sun's reflected light is absorbed by carbon dioxide and other air pollutants when they build up in the atmosphere. Global warming is the result of this, which causes an increase in the average surface temperature of the earth.
• The word "savanna" is derived from a prairie or plains word from Panama. Tall grasses grow all over them. Although there may have been a few plants and trees here and there, grass was still allowed to grow. The tropical grassland, like that seen in Africa, is the most typical definition of a savanna.
