The correct answer is: All of the above.
Bihar is a state in eastern India. It is located in the Indo-Gangetic Plain, which is a hot and humid region. The Himalayan region is located in the northern part of India. It is a mountainous region with a cold and dry climate.
The climate of Bihar is different from the climate of the Himalayan region in the following ways:
- Bihar is hotter and drier than the Himalayan region. The average temperature in Bihar is around 27 degrees Celsius, while the average temperature in the Himalayan region is around 15 degrees Celsius. Bihar also receives less rainfall than the Himalayan region. The average annual rainfall in Bihar is around 1,000 mm, while the average annual rainfall in the Himalayan region is around 3,000 mm.
- Bihar has colder winters than the Himalayan region. The average temperature in Bihar in winter is around 10 degrees Celsius, while the average temperature in the Himalayan region in winter is around 5 degrees Celsius.
These differences in climate are due to the different geographical features of the two regions. Bihar is located in a lowland region, while the Himalayan region is located in a mountainous region. The lowlands are warmer and drier than the mountains. The mountains also block the flow of moisture from the Indian Ocean, which is why the Himalayan region receives more rainfall than Bihar.
