Question

Read the graphs figure a and b and answer the following questions. Locate the places on the map:

1. 
   
   
   
2. 
   

1. Name the months of highest and lowest rainfall. What is the difference between the values of rainfall?
2. Name the months of highest and lowest temperatures.
3. Are the months of rainfall the same in both places? If not, why?
4. What could be the factors which influence the climate of these places?
5. What difference do you find between the previous and these graphs?
6. Write a concluding statement about the climate of both the places.

Answer 1

1. In Alice Springs, September is the driest month with around just 10 mm rainfall. Whereas the most precipitation falls in the month of January around 38 mm. The difference between the value is around 28 mm. Similarly, In Cairo, the driest month is May with no precipitation at all whereas it rains about 5 mm in the month of January. The difference between the values is just 5 mm.
2. The warmest month in Alice Springs is January with an average temperature of 38.7°C while July experiences the lowest temperature of about 11.5°C. In Cairo, July is the warmest month with 27.6°C, and the lowest temperatures are in January with around 13.1 °C temperature.
3. No, the months of rainfall are not the same in both the places because Alice Springs lies in the Southern Hemisphere while Cairo lies in the Northern Hemisphere.
4. Cairo in Egypt is located to the north of Tropic of Cancer, and Alice Springs is located just south of Tropic of Capricorn. Therefore, both the areas come under the subtropical high-pressure belts. The air becomes dry here. The winds in this region blow out of the region, so there is very low rainfall. The region of Alice Springs is part of the central Ranges scrub area of dry scrubby grasslands. The majority of Egypt's landscape is desert, hence extreme aridity is experienced.
5. In the previous graphs, rainfall is depicted for almost all the months. But in the graphs representing the climate of Alice Springs and Cairo, rainfall is very low or almost negligible. Temperature variation can also be depicted in the previous graphs and graphs of Alice Springs and Cairo.
6. Rainfall is very less in Alice Springs whereas almost negligible in Cairo. This is due to the latitudinal extent of both the places and subtropical high-pressure belts. Cairo is in or near the subtropical desert biome whereas Alice Springs is in or near the subtropical desert scrub biome. The average annual temperature is 35°C warmer. The average monthly temperature varies by 3. 7°C in Cairo.
