Earthquakes   Q. Which one of the following natural hazards is responsible for causing highest human disaster? (A) Earthquakes (B) Volcanic eruptions (C) Snow-storms (D) Tsunami नीचे लिखे प्राकृतिक खतरों में मनुष्यों के सर्वाधिक क्षति के लिए उत्तरदायी है ? (A) भूकंप (B) ज्वालामुखी का फूटना (C) बर्फीले तूफान (D) सुनामी The correct answer is: (A) Earthquakes Earthquakes are responsible for causing the highest number of human disasters among the options listed. They can lead to widespread destruction, including the collapse of buildings and infrastructure, triggering secondary hazards like tsunamis and landslides, and resulting in a high number of casualties, particularly in densely populated areas. Earthquakes are sudden, violent shaking of the ground caused by the movement of tectonic plates beneath the Earth's surface. They can occur without warning and vary in magnitude, with the most powerful quakes causing extensive damage and loss of lif...

Deforestation   Q. Deforestation during the recent decades has led to: ( A) Soil erosion ( B) Landslides ( C) Loss of bio-diversity ( D) All the above प्रश्न. हाल के दशकों में जंगलों के कटान का परिणाम निम्नलिखित हुआ है: ( A) भू-क्षरण ( B) भू-स्खलन ( C) जैवविविधता की क्षति ( D) उपरोक्त सभी The correct answer is: (D) All the above Deforestation has indeed led to soil erosion, landslides, and loss of biodiversity, among other environmental issues. Soil erosion is the process by which the upper layer of soil is worn away due to various factors, such as water, wind, and human activities. Deforestation significantly contributes to soil erosion because trees and vegetation play a crucial role in holding the soil together with their roots. When trees are removed, the soil becomes loose and more susceptible to being washed or blown away. Key effects of soil erosion include: Loss of fertile topsoil: The most nutrient-rich part of the soil is t...

Q . Circle graphs are used to show: ( A) How various sections share in the whole ( B) How various parts are related to the whole ( C) How one whole is related to other wholes ( D) How one part is related to other parts प्रश्न. "वृत्त ग्राफ" का उपयोग निम्नलिखित में से किसको प्रदर्शित करने के लिए किया जाता है ? ( A) विभिन्न खण्ड किस प्रकार पूर्ण का भाग बनते हैं ? ( B) विभिन्न भाग पूर्ण से किस प्रकार संबंधित हैं ? ( C) एक पूर्ण ( Whole) दूसरे पूर्णों ( Wholes) से किस प्रकार संबंधित है ? ( D) किस प्रकार एक भाग ( Part) दूसरे भागों से संबंध रखता है ? Circle graphs, also known as pie charts, are used to show: (A) How various sections share in the whole Explanation: A circle graph or pie chart represents data in a circular format, where the whole circle represents the total or 100% of the data. The circle is divided into sectors or "slices" that each represent a proportionate part of the whole. This makes it easy to visualize how different categori...

Q. Out of four numbers, the average of the first three numbers is thrice the fourth number. If the average of the four numbers is 5, the fourth number is: (A) 4.5 (B) 5 (C) 2 (D) 4 प्रश्न . चार संख्याओं में से पहली तीन संख्याओं का औसत चौथी संख्या का तिगुना है। अगर चार संख्याओं का औसत 5 है , तो चौथी संख्या क्या होगी ? (A) 4.5 (B) 5 (C) 2 (D) 4 Let's denote the four numbers as   a,   b,   c, and   d. We are given two key pieces of information: 1.     The average of the first three numbers   a,   b, and   c   is thrice the fourth number   d. 2.     The average of all four numbers is 5. From the first piece of information: a + b + c 3 = 3 d Multiplying both sides by 3 to clear the fraction: a + b + c = 9 d From the second piece of information: a + b + c + d 4 = 5 Multiplying both sides by 4 to clear the fraction: a + b + c + d = 20 We now have two equations: a + b + c = 9 d a + b + c = 9d a...

Q. A ratio represents the relation between: (A) Part and Part (B) Part and Whole (C) Whole and Whole (D) All of the above प्रश्न . अनुपात निम्नलिखित में संबंध दर्शाता है: (A) अंश और अंश का (B) अंश और पूर्ण का (C) पूर्ण और पूर्ण का (D) उपरोक्त सभी का A ratio represents the relation between: (D) All of the above Explanation: Part and Part (A) : A ratio can compare two parts of a whole. For example, in a classroom with 10 boys and 15 girls, the ratio of boys to girls is 10:15. Part and Whole (B) : A ratio can also compare a part to the whole. For example, in a classroom of 25 students (10 boys and 15 girls), the ratio of boys to the total number of students is 10:25. Whole and Whole (C) : A ratio can compare two wholes. For example, comparing the number of students in two different classrooms, one with 25 students and another with 30 students, gives a ratio of 25:30. Thus, a ratio can be used to represent the ...

Q. Which of the following methods is best suited to show on a map the types of crops being grown in a region: (A) Choropleth (B) Chorochromatic (C) Choroschematic (D) Isopleth प्रश्न . निम्नलिखित विधियों में से फसलों के प्रकार को नक्शे पर प्रदर्शित करने के लिये कौन सी विधि सबसे उपयुक्त है ? (A) कोरोप्लेथ (B) कोरोक्रोमेटिक (C) कोरोस्कीमेटिक (D) आइसोप्लेथ To show on a map the types of crops being grown in a region, the best suited method is: (B) Chorochromatic Reasons for Choosing Chorochromatic: 1.     Distinct Categories : Chorochromatic maps are used to represent distinct, categorical data, such as different types of crops. 2.     Visual Clarity : Each category (or crop type) is represented by a different color or pattern, making it easy to distinguish between different crops. 3.     Non-Numerical Data : This method is ideal for non-numerical data, where the goal is to show the presence or absence of a category ...

Q. Which of the following methods will you choose to prepare choropleth map of India showing urban density of population: (A) Quartiles (B) Quintiles (C) Mean and SD (D) Break point प्रश्न . शहरों में जनसंख्या के घनत्व को दिखाने के लिए कोरोप्लेथ नक्शा हेतु निम्नलिखित में से कौन सी विधि चुनेंगे ? (A) क्वार्टाइल्स (B) किंवटिलेस (C) मीन और एस.डी. (D) ब्रेक-प्वाइंट To prepare a choropleth map of India showing urban density of population, you would choose a method that effectively represents the distribution of data across different areas. Among the given options, the most appropriate method is: (A) Quartiles Reasons for Choosing Quartiles: 1.     Data Distribution : Quartiles divide the data into four equal parts, making it easier to understand the distribution and compare different regions. 2.     Interpretability : Quartiles are simple to interpret and provide a clear representation of how the urban density of population varies acr...
