What is weather?
✅ Weather is the atmospheric condition of a place at a specific time, such as temperature, humidity, rainfall, and wind speed. It changes daily.
What causes variation in climate across India?
✅ Due to factors like latitude, altitude, distance from the sea, relief features, and pressure & wind systems.
Define monsoon.
✅ Monsoon refers to the seasonal reversal in the wind direction, especially the southwest winds bringing heavy rainfall in summer.

Explain the role of Himalayas in influencing India’s climate.
✅ The Himalayas act as a barrier to cold winds from Central Asia, protecting northern India from extreme cold. They also force monsoon winds to rise, causing orographic rainfall, especially in the foothills.
What is the impact of the monsoon on Indian agriculture?
✅ Indian agriculture heavily depends on the monsoon. A good monsoon ensures good crop yield, while failure of monsoon can cause droughts, crop failure, and food scarcity.
What is El Niño and how does it affect India?
✅ El Niño is the abnormal warming of the central and eastern Pacific Ocean. It disrupts the Indian monsoon system, often leading to weak rainfall and droughts.

Describe the four main seasons in India as per the Indian Meteorological Department.
✅ The four main seasons in India are:
- Cold Weather Season (Winter) – December to February. Cool and dry winds blow; western disturbances bring some rainfall to the north.
- Hot Weather Season (Summer) – March to May. High temperatures, low humidity, and formation of low-pressure areas.
- Southwest Monsoon Season – June to September. Moist winds from the Indian Ocean cause heavy rainfall in most parts of the country.
- Retreating Monsoon (Post-monsoon) – October to November. Winds retreat; rainfall shifts to the southeast coast (e.g., Tamil Nadu).
Explain the mechanism of the monsoon in India.
✅ During summer, land heats up faster than the sea, creating a low-pressure area over the Indian subcontinent. Moist winds from the Indian Ocean are attracted to this region, resulting in the Southwest Monsoon. These winds split into the Arabian Sea and Bay of Bengal branches, causing widespread rainfall. The retreat of the monsoon begins in October as the land cools, and dry winds start blowing outwards, leading to the Retreating Monsoon.
