Water Class 7 Case Study

Case Study Question 1:

The Earth is covered by three-fourth of water, 97.3% water is saline or salty in oceans and seas and 2% is fresh water that consists of ice-caps, ground water, fresh water lakes, inland and salt lakes. Many countries are facing water scarcity and adding to this fact whatever water is available, is also not fit for drinking because it is polluted fully. The Sun’s heat causes evaporation of water into vapour. When the water vapour cools down, it condenses and forms clouds. From there, it may fall on the land or sea in the form of rain, snow or sleet. The process by which water continually changes its form and circulates between oceans, atmosphere and land is known as the water cycle. Our Earth is like a terrarium. The same water that existed centuries ago still exists today. The water used to irrigate a field in Haryana may have flowed down the Amazon River a hundred years ago. The major sources of fresh water are the rivers, ponds, springs and glaciers. The ocean bodies and the seas contain salty water. The water of the oceans is salty or saline as it contains large amount of dissolved salts. Most of the salt is sodium chloride or the common table salt that you eat.

What is Case Study Question in Class 7 Social Science?

Case study questions typically present a specific scenario or case related to a historical event, geographical issue, or social problem. Students are expected to read and understand the details of the case and then answer a set of questions based on their understanding and knowledge of the subject matter.

Case study questions can be an effective way to assess students’ understanding and ability to apply social science concepts to practical situations. They also encourage students to think critically, analyze information, and draw informed conclusions – skills that are valuable both inside and outside the classroom.
