The correct answer is: a) Tropical monsoon climate.
Bihar experiences a predominantly tropical monsoon climate. This type of climate is characterized by hot, humid summers and warm, dry winters. The monsoon season, which lasts from June to September, brings heavy rains and flooding. The rest of the year is relatively dry.
The tropical monsoon climate is caused by the difference in temperature between the land and the ocean. During the summer, the land heats up faster than the ocean, causing the air to rise. This creates an area of low pressure over the land, which draws in moist air from the ocean. The moist air rises and cools, condensing into clouds and rain.
The monsoon season is a time of great agricultural activity in Bihar. The rains provide the water necessary for crops to grow. However, the monsoon can also be destructive, causing flooding and landslides.
The other options are incorrect because they do not describe the climate of Bihar accurately.
- Temperate climates are characterized by warm summers and cool winters. Bihar does not experience this type of climate.
- Arid climates are characterized by low rainfall. Bihar does not experience this type of climate.
- Mediterranean climates are characterized by warm, dry summers and cool, wet winters. Bihar does not experience this type of climate.
