Geography

Bihar is mainly a vast stretch of very fertile land. It has many rivers including Ganga, Son, Bagmati, Kosi, Budhi Gandak, and Falgu. Central parts of Bihar has some small hills, including Rajgir hills. Nepal is to the north of Bihar. To get to the Himalayas one will have to enter Nepal and travel for around 50-100kms.

After the division of the state in 2000, when the industrial and the mineral rich part of the state was carved out as a separate state of Jharkhand, the main economic activity of the state has been agriculture. Bihar is one of the poorest states of India. Blames for this are put on many factors - a historical disfavour from the center of Indian power (be it Calcutta during the British empire or Delhi during the independent India), a deeply polarized and highly politicized society, power hungry and corrupt rulers, lack of social reform movements, etc.

Climate

It is mildly cold in the winter (worst it could get is 5-10 degrees Celsius). Winter months are December and January. It is very hot in the summer (40-45 degrees). April, May and first half of June are the hot months. Then comes the monsoon in the months of June, July, August, and September. October, November, February, and March are very pleasant months.
