NTA UGC NET/JRF Exam, Dec. 2020/June, 2021 Geography

Total Questions: 100

91. Read the following passage carefully and answer the question 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 forces, while short-term changes are 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 greenhouse 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 activities do not accentuate short-term changes in atmospheric composition?

Correct Answer: (b) Astronomical forcing
Solution:

Astronomical forcing does not accentuate short-term changes in atmospheric composition as para says, "Long-term changes are ascribed to astronomical forcings, while short-term changes are linked to anthropogenic factors causing changes in atmospheric composition, including aerosol loading."

92. Which of the following elements is not associated with climate change?

Correct Answer: (b) Upwelling interactions
Solution:

Upwelling interaction is not associated with climate change as para says, "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."

93. Which one of the following rates of increase have been observed in global temperature in recent times?

Correct Answer: (c) 0.5°C
Solution:

According to the paragraph 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.

94. Which one of the following will be mean global temperature increase range till the year 2100?

Correct Answer: (c) 1.4-5.8 °C
Solution:

As paragraph depicts, "climate change predictions with GCMs are under taken for next 100 years depending on emission scenarios for greenhouse gases and aerosols the mean global temperature may increase in the range of 1.4 to 5.8°C. together with sea level rise."

95. Which of the following conditions is essential for future research with respect to climate change?

Correct Answer: (d) Atmospheric modelling
Solution:

Atmospheric modelling is essential for future research with respect to climate change. Atmospheric modelling is an important method to generate physical and numerical measurements of climate parameters, quantity the spatiotemporal changes of atmospheric phenomena over space and time, and predict their occurrences.

96. Read the following passage carefully and answer the question 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.
If 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 taken at least three distinct forms. The earliest emerging in the 1960s, focused on the systematic study of population distribution as a whole and spatial variations in dynamic characteristics of population. Trewartha, Zelinsky, WAV Clark and other from USA 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 rates 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 vital statistics is related with demographie characteristics of population studied in Population Geography

Correct Answer: (c) Birth, deaths, marriage/migration
Solution:Birth, deaths, marriage/migration are related with demographie characteristics of population studied in Population Geography.

97. Which one of the following population characteristics does not belong to vital statistics?

Correct Answer: (c) Age and sex
Solution:

According to the paragraph Age and sex does not belong to vital statistics. As paragraph says Population geography has widened its scope to cover different variety of themes with time. It studies various population characteristics including gender, religion, age, disability rate by grouping population characteristics into political and administrative units. All such variables go far beyond the vital statistics of births, deaths and marriage /migrations.

98. Who among the following is not a U.S. Geographer pioneering population geography as a part of spatial science?

Correct Answer: (b) Pierre George
Solution:

Pierre George is not a U.S. Geographer pioneering population geography as a part of spatial science. Trewartha. Zelinsky, WAV Clark and other from USA 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 rate by grouping population characteristics into political and administrative units. All such variables go far beyond the vital statistics of births, deaths and marriage /migrations.

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

Correct Answer: (c) Sociology, Demography and Economics
Solution:Disciplines like Sociology, Demography and Economics other than geography, has contributed significantly to studies in population geography.

100. In which of the following decades, Population Geography greatly focused on the systematic study of distributions and spatial differentiations in various attributes of population characteristics

Correct Answer: (a) 1950s
Solution:

The geographical study of population, including its spatial distribution, dynamics and movement. As a sub discipline, it has taken at least three distinct but related forms, the most recent of which appears increasingly integrated with human geography in general. The earliest and most enduring form of population geography emerged from the 1950's onwards, as part of spatial science.
