How does the Himalayas affect the climate of South Asia? 

The Himalayas have a profound influence on the climate of South Asia, serving as a crucial natural factor in shaping the region's climatic characteristics. Below are suggested answers to the question "How does the Himalayas affect the climate of South Asia" for students to refer to.

1. Blocking cold winds from the North

- Role of blocking wind:

+ The Himalayas lie to the north of South Asia, stretching over 2400 km with an average height of over 6000 meters, acting as a natural barrier preventing cold air masses from Central Asia from descending into South Asia during winter.

- Result:

+ This helps South Asia maintain a warm climate in winter, even in higher latitudes. Regions like the Ganges plains and the southern coastal areas retain relatively high temperatures.

2. Facilitating the summer monsoon

- Monsoon effect:

+ In summer, the Himalayas act as a giant wall, blocking moist air masses from the Indian Ocean. When these moist air masses are blocked and pushed upward, they cool down, condense, and cause heavy rainfall in South Asia.

- Consequence:

+ Consequently, South Asia experiences a prolonged rainy season from June to September, with high average rainfall, especially in windward regions such as Assam, Meghalaya, and the Western Ghats.

+ The plains and lowlands of South Asia receive significant rainfall, crucial for maintaining agricultural production, particularly rice – a crop dependent on rainwater.

3. Impact on the inland climate

- Creating a rain shadow region:

+ North of the Himalayas (Tibet), areas fall in the rain shadow being sheltered from moist air masses. This results in the Tibetan Plateau and surrounding regions being drier and much colder compared to the southern side of the mountains.

- Distinct climate differentiation:

+ South Asia's climate becomes diversified, with marked differences between the humid south and the dry, cold north.

4. Influence on winter and winter rainfall

- Winter rain in northern South Asia:

+ The Himalayas draw air masses from the Arabian and Mediterranean seas during winter, causing light but important rainfall for the Punjab and Northwest India region. This creates favorable conditions for winter crops like wheat.

5. Contribution to water resources and river systems

- Water source from melting snow:

+ Snow on the Himalayas melts in spring and summer, supplying water to major rivers like the Ganges, Indus, and Brahmaputra. This is a vital water source for irrigation, domestic use, and industry in South Asia.

- Climate regulation for downstream regions:

+ Major rivers help maintain humidity and regulate the climate for the vast plains of South Asia.

6. Impact on extreme weather phenomena

- Blocking storms from Central Asia:

+ The Himalayas weaken strong windstorms from the north, reducing the impact of cold spells on South Asia.

- Amplifying heavy rain:

+ When the monsoon winds hit the mountains, heavy rain occurs, sometimes causing floods in windward areas. An example is the Cherrapunji region in Meghalaya, one of the highest rainfall places in the world.

7. Indirect impact on ecosystems and economy

- Ecosystem:

+ The Himalayas create diverse climates from tropical at the foothills to cold climates at high altitudes, forming rich and unique ecosystems.

- Economy:

+ The Himalayas influence on rainfall and river water resources strongly supports agricultural production, particularly in the river plains of the Indus, Ganges, and Brahmaputra.

8. Conclusion

The Himalayas play a decisive role in shaping the climate of South Asia, not only resulting in a warm, humid climate for the region but also facilitating socio-economic development. However, extreme weather phenomena like flooding from heavy rains and reliance on water from melting snow also pose challenges for the area.

What are the specifications of specialized classrooms in a lower secondary school in Vietnam?

Based on Article 5 of the Regulations on specialized classrooms of general education institutions issued with Circular 14/2020/TT-BGDDT, the specifications for specialized classrooms in lower secondary schools are as follows:

(1) Minimum working area per student for specialized classrooms:

- For Natural Sciences, Informatics, Foreign Languages, and Multidisciplinary classrooms, the minimum working area per student is 1.85m2, and each room has an area of not less than 60m2;

- For Technology, Music, and Art classrooms, the minimum working area per student is 2.25m2, and each room has an area no less than 60m2;

- Social Sciences classrooms (shared for Civic Education, History, and Geography) have a minimum working area per student of 1.50m2, and each room is not less than 60m2.

(2) Dimensions of specialized classrooms

- The width of specialized classrooms (measured perpendicular to the corridor adjacent to the classroom): Not less than 5.70m for primary schools; not less than 7.20m for secondary, high schools;

- The length of specialized classrooms (measured along the corridor adjacent to the classroom) not more than twice the width;

- The height of specialized classrooms (measured from the floor/ground to the ceiling) from 3.30m or higher. If using false floors/ceilings to accommodate technical systems beneath, the height of specialized classrooms (from floor/ground to ceiling) should not be less than 2.80m.

(3) Natural Sciences, Technology, Physics, Chemistry, Biology classrooms, and some subjects with multiple practical devices must have a preparation room. This preparation room is arranged next to, with an interconnecting door to the specialized classroom with a working area from 12m2 to 27m2.

What are the requirements for teaching equipment in specialized classrooms in Vietnam?

Based on clause 2 of Article 7 of the Regulations on specialized classrooms of general education institutions issued with Circular 14/2020/TT-BGDDT, the requirements for teaching equipment in specialized classrooms are as follows:

- Fully equipped with devices listed in the teaching equipment corresponding to each type of specialized classroom as regulated by the Minister of Education and Training;

- Encouraged to equip additional devices to meet the requirements of teaching method innovation, applying new technologies, enhancing students' experimental and practical skills; supporting teaching, scientific research, and career education orientation in general education institutions;

- Teaching equipment in specialized classrooms is arranged and organized in a logical, scientific manner, suitable in terms of technical requirements, utility, and subject content to ensure convenience in using and preserving without diminishing the functionality of each specialized classroom;

- Chemicals are arranged, organized, and stored separately to prevent affecting or damaging other teaching equipment.
