2. Very Short Answer (VSA).

Q1. Define ‘weather’.

Answer: Weather is the state of the Earth's atmosphere at a particular time and place. It includes conditions like temperature, humidity, wind, and precipitation.

Q2. Name any two elements of weather.

Answer: Two elements of weather are temperature and humidity.

Q3. What is precipitation?

Answer: Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from the atmosphere to the Earth's surface.

Q4. Name the instrument used to measure wind speed.

Answer: Wind speed is measured using an anemometer.

3. Short Answer Questions.

Q1. Differentiate between weather and climate with one example.

Answer: Weather refers to day-to-day atmospheric conditions at a place, such as a rainy day in July. Climate is the average weather pattern over a long period, like "Delhi has a hot summers and cold winters" reflecting its regional climate.

Q2. Why is humidity important for daily life?

Answer: Humidity affects how comfortable we feel, influences the drying of clothes, and impacts activities such as agriculture, food processing, and preservation in museums. High humidity slows evaporation, making the air feel warmer and increasing sweat.

Q3. State one advantage of using weather prediction in agriculture.

Answer: Weather prediction helps farmers plan sowing, irrigation, and harvesting, which protects crops from untimely rain or drought and improves yield.

Q4. What is the role of barometer in weather observation?

Answer: A barometer measures atmospheric pressure. Sudden drops in pressure can signal storms or cyclones, enabling timely warnings and preparation.

4. Long Answer Questions.

Q1. Explain how different weather instruments help us record and predict the weather.

Answer: Weather instruments like thermometers, rain gauges, barometers, anemometers, and hygrometers measure temperature, rainfall, air pressure, wind, and humidity. Their readings, collected at weather stations, allow meteorologists to monitor weather changes and make reliable forecasts. This information helps people prepare for extreme events and manage daily life.

1. Record temperature with a thermometer.
2. Measure rainfall using a rain gauge.
3. Track air pressure with a barometer.
4. Use an anemometer for wind speed and a wind vane for direction.
5. Check humidity with a hygrometer.

Q2. Describe with an example how humans have traditionally predicted the weather using signs from nature.

Answer: Before modern tools, people watched natural signs to predict weather. For example, ants moving eggs to higher ground, frogs croaking more often, or pine cones closing are seen as signs of imminent rain. Such observations helped communities prepare for rain, storms, or dry spells long before scientific instruments were available.

1. Observe animal/insect behavior changes.
2. Note plant responses like pine cone movement.
3. Share and pass down this knowledge.

Q3. Analyze the following temperature data for a city in Madhya Pradesh and answer: What are the maximum and minimum temperatures during the week, and what is the range?

Answer: From the table, the maximum temperature is 32°C, and the minimum is 14°C. The range of temperature is obtained by subtracting the minimum from the maximum: 32°C - 14°C = 18°C. This shows how temperatures can vary over a week.

1. Identify the highest temperature: 32°C.
2. Identify the lowest temperature: 14°C.
3. Calculate range: 32°C - 14°C = 18°C.

Q4. Explain why weather predictions are becoming increasingly important in recent years.

Answer: Weather predictions matter more now due to climate change, which causes more frequent droughts, floods, cyclones, and heat waves. Accurate forecasts help people, farmers, and governments plan, prepare, and stay safe by responding quickly to extreme weather events, reducing damage and loss.

1. Climate change increases severe weather.
2. Predictions guide preparation and safety.
3. Helps protect life, crops, and property.

4. True or False Questions.

Q1. Wind moves from low-pressure areas to high-pressure areas.

Answer: False

Q2. A hygrometer is used to measure humidity.

Answer: True

Q3. The rain gauge measures wind speed.

Answer: False

Q4. The troposphere is the layer of atmosphere where almost all weather phenomena occur.

Answer: True

5. Match the Following Questions.

Q1. Match the following weather instruments to the element they measure.

Answer: 1 - A, 2 - B, 3 - C, 4 - D, 5 - E

3. Fill in the Blanks Questions.

Q1. The __________ measures the amount of rainfall at a place.

Answer: rain gauge

Q2. The movement of air is called __________.

Answer: wind

Q3. The layer of the atmosphere where almost all weather phenomena occur is __________.

Answer: troposphere

Q4. __________ is the amount of water vapour present in the air.

Answer: Humidity
