7 th Social Science Ch 2 Understanding the Weather NCERT QUESTIONS ANSWERS Discussion

Social Science class 7 chapter number two and chapter name is understanding the weather. So children in this video we are going to understand we are going to discuss question answer NCRT question answers of this chapter right. So here we start our first question here it is it is matching based match the instrument with the weather elements it measures. So children there are instruments like hydrometer, animometer, barometer, thermometer and rain gaze right and weather elements are precipitation, atmospheric pressure, temperature, wind direction, humidity these are there, right? So let's match these. First one is hydrometer. So hydrometer is used to measure humidity. Next one is animometer. So animometer measures wind direction and speed. Third is barometer. Barometer is used to measure atmospheric pressure. Next is four that is thermometer. Very simple. It is used to measure temperature in degrees Celsius or in degree Fahrenheit. Right? Next is point number five. This is rain gauge. So this measures precipitation means rainfall. So this is it. hope you got it. Question number two is Josina is deciding what clothes to pick for her school trip to Mumbai in June. Children in this chapter you have studied different you know weather condition and climates of our country in different areas in different times you have studied. So now you see the condition of Josnas is going to Mumbai in the month of June. Right here it is. And this time around 29 and 30° temperature is there little high temperature and humidity is around 80 to 90 84 here mentioned around 80 to 90 uh% humidity is there because this is the time of arrival of monsoon right so what suggestions you will provide her so here your advice here what advise this is point number one light go certain clothes she should carry with her. Point number two is comfortable footwear. Point number three is need to carry umbrella and raincoat. Right? Because this is monsoon season. And point number four is carry bottle and cap to stay hydrated and avoid discomfort and from the sticky weather. Right here it is. So she should avoid woolins or heavy fabric since the weather will be warm and very humid. So these are the suggestion for jots. Light cotton clothes, comfortable footwear, umbrella and carry bottle cap. These are next is question number three. So question number three is imagine that small group of students is setting up rain gaze. Right? So here are some options for the site means students are having rain gauge. They need to do site selection to establish the rain gauge and to measure the rain. Fine. This they need to do. So here are some site options are given. first is the school vegetable garden. Second the terrace of school building. Third open ground with elevated platform. and four is compound wall of school. Fifth is veranda of the school library. Right? So discuss in your group and finalize the site. So final decision option number two and three. Why option number two and three? Let's check which are these option number two and three. So these are option number two terrace of the school building and option number three ground open ground with elevated platform. Here it is right. So why these are in selection? So rain gauge should be placed in an open area to receive undisturbed rainfall. So that is why there should be open platform. There should be open space no disturbance. The terrace is open and away from trees and buildings. Clear? Next. Elevated platform in open ground ensure the rain gauge is above the ground level and away from splashing water because splashing water can give you know wrong reading of rain gauge. And next is other options may give incorrect reading due to obstructions like trees, walls or roof. So there should be no any kind of you know obstructions and you know things which can disturb our result which can manipulate our result right. So rain gaze you know very well it is measure the amount of rainfall in given area as you can see here the place should be open away from walls roofs and trees there should be elevated platform provide accurate reading. So an ideal site for rain gaze is open, elevated and free from any obstructions to ensure accurate rainfall measurement. So you got the answer. Now let's go to last question. So here the last question is below is chart taken from IMD. IMD means Indian materiological department right which measure the atmospheric condition and give predictions about it do weather forecast Jammu and Kashmir so it is the chart showing the weather condition of Jammu and Kashmir looking at the data available write short script to report the weather condition in different parts of Jammu and Kashmir means you need to read this chart and you need to do weather reporting and hint cover the temperature range, maximum, minimum temperatures, humidity, precipitation. So you need to be you need to work like weather reporter. Fine. Here is the chart. This is which is given in your book with this question. So your script will be something like this. So on the 1st February 2024 evening, Sinodar was the warmest with the maximum temperature of 6.5° and minimum of -2.4°C. Other places were cooler with Gulmar having the lowest maximum temperature. So this way you need to speak it all right with the help of map. So children you need to understand one thing. These are four questions only in this chapter. So you need to understand in your exams you may have question in some different ways also like here Jodna is going to Mumbai there can be Mr. Moan is planning to go to Rajasthan in January, right? And there is Sonu is going to plan going planning to go to Megalia in March, right? So different time can be given, different areas can be given and questions can be asked to you. So with the understanding of this chapter, right, you need to frame your points and you need to write. So answer with active brain. Then you see question number three. Imagine that small group of students setting up rain gaze. So in place of rain gaze there can be thermometer, there can be wind vein, right? There can be animometer and there can be rain gaze. So many things, many instruments can be there. Right here it is. And in this place question number four, this is the chart of Jammu and Kashmir. So there can be chart of any other place any other time. So you need to answer according to the given question. Apply your knowledge and answer it. Here it is. So there are only four NCERD question answers in this. So if you want more questions, so I'll upload one more video having practice questions. Okay. So thanks for watching. Have nice day.
