  10. Directions (Q. No. 91 to 95): Read the following passage carefully and answer the questions given below.Climate change involves both internal and external factors. External one includes solar variability, astronomical effects on the earth’s orbit and volcanic activity whereas internal one includes natural variability in the system, feedbacks within atmosphere, ocean and land surface. Recently, human-induced climate change on global and local scale has become a reality, primarily through changes in atmospheric composition and surface properties. Climate changes involve continental drift, volcanic activity and solar output. Glacial interglacial cycles have been controlled by astronomical variations. The global temperature has Increased by 0.5°C with greatest in the middle latitudes with warming particularly during the 1920 to 1940s and 1990s with several warmest years. Long-term changes are ascribed to astronomical forcings, while short-term changes linked to anthropogenic factors causing changes in atmospheric composition, including aerosol loading, depletion of ozone, destruction of vegetation etc. Recently, climate change predictions with GCMs are under taken for next 100 years depending on emission scenarios for green house gases and aerosols the mean global temperature may increase in the range of 1.4 to 5.8°C, together. with sea level rise. To conclude, critical research data on cloud cover, radiation, ocean processes atmospheric coupling and feedback processes in the context of climate change are required.Which of the following elements is not associated with climate change?

    1. Solar variability
    2. Upwelling interactions

  16. Directions (Q. No. 96 to 100): Read the following passage carefully and answer the questions given below:Population Geography, a sub field of Geography, studies spatial variations in distribution, composition, migration and growth of population to the terrain, in a way it involves demography in geographic perspective.It focuses on questions such as where populations are found and how the size and composition of these populations is regulated by demographic processes of fertility, mortality and migration. Contributions to population geography are cross-disciplinary. Disciplines other than geography contributing to population geography include demography, sociology and economics.Since its inception, population geography has a taken at least three distinct forms. The earliest emerging in the 1950s, focused on the systematic study of population distribution as a whole and spatial variations in dynamic characteristics of population. Trewartha, Zelin sky. W.A.V Clark and other from U.S.A. and J.B Garnier and Pierre George in France Pioneered this phase.Population geography has widened its scope to cover different variety of themes with time. It studies various population characteristics including gender, religion, age, disability, race etc. by- grouping population characteristics into political and administrative units. All such variables go far beyond the vital statistics of births, deaths and marriage/migrations.Geographers have studied relations between demographic growth, displacement and access to resources at the International scale. Examples are density maps prepared using choropleth, isoline and dots.Which one of the following population characteristics does not belong to vital statistics?

    Options:
    1. Births
    2. Deaths
    3. Age and sex

  17. Which one of the following group of disciplines, other than geography, has contributed significantly to studies in population geography?

    3. Sociology, Demography and Economics
    4. Economics, Sociology and History

    Option: C

  18. Which one of the following vital statistics is related with demographic characteristics of population studied in Population Geography?
