Case Study Questions
Read the passage given below and answer the questions that follow:
One of the earlier and popular arguments was by German philosopher Immanuel Kant. Mathematician Laplace revised it in 1796. It is known as Nebular Hypothesis. The hypothesis considered that the planets were formed out of a cloud of material associated with a youthful sun, which was slowly rotating.
Later in 1900, Chamberlain and Moulton considered that a wandering star approached the sun. As a result, a cigar-shaped extension of material was separated from the solar surface. As the passing star moved away, the material separated from the solar surface continued to revolve around the sun and it slowly condensed into planets. Sir James Jeans and later Sir Harold Jeffrey supported this argument. At a later date, the arguments considered of a companion to the sun to have been coexisting. These arguments are called binary theories. In 1950, Otto Schmidt in Russia and Carl Weizascar in Germany somewhat revised the nebular hypotheses, though differing in details. They considered that the sun was surrounded by solar nebula containing mostly the hydrogen and helium along with what may be termed as dust. The friction and collision of particles led to formation of a disk-shaped cloud and the planets were formed through the process of accretion.
(i) Name the hypothesis derived by Mathematician Laplace related to origin of the Earth.
Ans. Nebular Hypothesis.
(ii) What were the views of Chamberlain and Moulton on the origin of the Earth and other planets?
Ans. They proposed that a wandering star approached the sun. As a result, a cigar-shaped extension of material was separated from the solar surface. As the passing star moved away, the material separated from the solar surface continued to revolve around the sun and it slowly condensed into planets.
(iii) What was the composition of solar nebula at the initial time?
Ans. Solar nebula contained mostly the hydrogen, helium and the dust.
(iv) Explain the process of accretion in the formation of planets.
Ans. Accretion is the process in which solids agglomerate to form larger and larger objects and eventually planets are produced.

Importance of Practicing Case Based and Passage Based Questions for Class 11 Geography
Practicing case study and passage-based questions in Class 11 geography is pretty valuable. Here’s why:
- Real-world Application: Geography often deals with real-world situations. Case studies help you apply your theoretical knowledge to practical scenarios, making your learning more meaningful.
- Analytical Skills: These questions require you to analyze information from passages and case studies, honing your analytical skills. This is crucial not just for exams but for understanding complex geographical issues in the world.
- Understanding Different Perspectives: Geography involves diverse perspectives on issues like climate change, urbanization, and resource management. Working on case studies helps you appreciate different viewpoints and develop a well-rounded understanding.
- Exam Preparation: Since these types of questions are common in exams, practicing them prepares you for what to expect. It ensures you’re comfortable tackling such questions during the actual test.
- Enhanced Research Skills: Case studies often require additional research to fully comprehend the context. This enhances your research skills, an important aspect of studying geography.
- Critical Thinking: Dealing with passages and case studies encourages critical thinking. You’re not just memorizing facts; you’re evaluating information and forming reasoned conclusions.
- Practical Application of Concepts: Geography isn’t just about memorizing facts and figures. Case studies allow you to practically apply the concepts you’ve learned in the classroom to real-world situations.
