Bhutan is a mountainous country bounded by China in the north and India in the south. The height ranges from:
Correct Answer
D. 200m in the south to 7000m in the north
Explanation
Bhutan is a mountainous country with varying elevations. The given answer, "200m in the south to 7000m in the north," suggests that the height ranges from a low of 200 meters in the southern part of the country to a high of 7000 meters in the northern part. This indicates a significant difference in altitude within Bhutan, with much higher elevations in the north compared to the south.
2.
The general climatic conditions in Bhutan are categorized into four zones. Some of these zones receive the least rainfall and some receive the heaviest. Which of the following zone receives the heaviest rainfall?.
Correct Answer
D. The Sub-Tropical zone
Explanation
The Sub-Tropical zone receives the heaviest rainfall in Bhutan.
3.
Many factors influence the climate in Bhutan. Some of the factors are:
1). Prevailing wind direction
2). The orientation of mountain ranges
3). Distance from sea
4). Local winds
Choose the most appropriate factors.
Correct Answer
D. 1, 2 and 4
Explanation
The prevailing wind direction, the orientation of mountain ranges, and local winds are the most appropriate factors that influence the climate in Bhutan. Prevailing wind direction affects the movement of air masses and the distribution of rainfall. The orientation of mountain ranges influences the amount of rainfall received and creates microclimates. Local winds, such as valley winds or mountain breezes, also play a role in shaping the climate. Distance from the sea, which is not included in the selected factors, can also have an impact on climate patterns.
4.
The existence of great mountain ranges in the north affects the climate of Bhutan. Do you agree?. Support your answer with TWO reasons.
Correct Answer
A. True : The mountain ranges acts as a barrier for the seasonal winds which are also known as monsoons that blows during summer. This enables our country to receive rainfall which is extremely useful for our agriculture.
Explanation
The existence of great mountain ranges in the north affects the climate of Bhutan because they act as a barrier for the seasonal winds, known as monsoons, that blow during summer. This barrier prevents the monsoons from reaching other areas and directs them towards Bhutan, resulting in rainfall that is crucial for agriculture.

The sun's rays fall vertically over the two tropics once a year. On which date, do the sun's rays fall vertically over the tropic of cancer?.
Correct Answer
Ans: 21st June
Explanation
On 21st June, the sun's rays fall vertically over the Tropic of Cancer. This date marks the summer solstice in the Northern Hemisphere, when the sun reaches its highest point in the sky and the daylight hours are the longest. The Tropic of Cancer is located at 23.5 degrees north of the equator, and on this specific date, the sun is directly overhead at this latitude, resulting in the vertical rays.
6.
Alpine zone is one of the climatic zones of our country. All the following features describe the zone, EXCEPT?
Correct Answer
D. The annual rainfall varies from 1000mm to 1500mm.
Explanation
The correct answer is "The annual rainfall varies from 1000mm to 1500mm." This is because the other three features mentioned - a short growing season, snowfall and frost in winter, and remaining cold even in summer - are all characteristics of the alpine zone. The annual rainfall, however, is not a defining feature of the alpine zone.
7.
Which of the following is Not a feature of the summer season?
Correct Answer
A. The southern foothills become warm and pleasant.
Explanation
The given statement states that the southern foothills become warm and pleasant, which is not a feature of the summer season. Summer season is typically characterized by hot weather, longer days, and higher temperatures. The statement contradicts this by suggesting that the southern foothills become warm and pleasant, which implies a cooler and more pleasant climate.
8.
The ground temperature begins to rise, plants starts growing and birds migrate to their higher altitude habitat. The above statement BEST describes the spring season.
Correct Answer
A. True
Explanation
The given statement accurately describes the characteristics of the spring season. During spring, the ground temperature starts to rise, which allows plants to grow. Additionally, birds migrate to their higher altitude habitats during this time. Therefore, the statement is true.
9.
The climatic conditions in the southern foothills is better suited for human settlement than the other zones as it experiences warm and pleasant weather conditions and it has vast plain with fertile soil.
Correct Answer
A. True
Explanation
The explanation for the given correct answer is that the climatic conditions in the southern foothills are better suited for human settlement compared to the other zones. This is because the area experiences warm and pleasant weather conditions, which are generally more comfortable for people to live in. Additionally, the southern foothills have vast plains with fertile soil, which is beneficial for agriculture and can support a larger population. Therefore, it is true that the climatic conditions in the southern foothills are better suited for human settlement than the other zones.
