Important exam questions with answers
What is the difference between weather and climate?
Weather is the atmospheric condition at a specific place and time, such as rain today. Climate is the average weather condition of a place over a long period, usually 30 years or more. (2 points)
Explain why the Thar Desert experiences a large difference between day and night temperatures.
The Thar Desert has dry air and clear skies, so heat escapes quickly at night causing a large temperature drop. During the day, temperatures can reach up to 50°C, but at night it can fall to around 15°C. (2 points)
Which part of India receives rainfall during the northeast monsoon, and why?
The Tamil Nadu coast receives rainfall during the northeast monsoon in October and November because winds blow from land to sea, bringing moisture to this region. (2 points)
FAQ
What causes the seasonal reversal of winds in India?
The seasonal reversal of winds, called the monsoon, happens because of temperature differences between land and sea. Harshali Academy’s audio lessons explain this clearly.
Why do coastal areas have less temperature variation between day and night?
Coastal areas have less temperature variation because the sea heats and cools slowly, moderating the climate. You can listen to detailed explanations on Harshali Academy.
How does climate affect the way people build houses in India?
People build houses with thick walls and flat roofs in deserts to keep heat out, while in rainy areas, sloping roofs help water flow down. Harshali Academy covers these adaptations in detail.
What are the main elements of weather and climate?
The main elements are temperature, atmospheric pressure, wind, humidity, and precipitation. These are important for understanding climate patterns.
Why does Meghalaya receive more rainfall than Rajasthan?
Meghalaya receives over 400 cm of rainfall due to moist winds from the Bay of Bengal, while Rajasthan is dry because it lies in the rain shadow region. Harshali Academy’s lessons explain this well.
