41. In which of the layers temperature decreases as altitude increases?

A. Thermosphere           C. Mesosphere
B. Troposphere               D. Stratosphere from the options given below:
Choose the correct answer

Correct Answer: (b) B and C only
Solution:

In Troposphere and Mesosphere temperature decreases as altitude increase. In troposphere as one goes upwards, temperature falls at rate of 6.5°C per kilometer and reaches -45°C at the poles and -80°C over the equator in the topmost layer.
In stratosphere temperature remains constant for some distance but rises to reach a level of 0°C at 50 km. In mesosphere temperature decreases and reached it's minimum mark averaging -90°C in the topmost layer of it. In thermosphere temperature rises rapidly with increasing height. Temperature gradually increase in Exosphere.

Choose the correct answer from the options given below:

Correct Answer: (d) B, C and D only

A. Aerosols include sea salts, fine soil, smoke, pollens, soot.
B. Aerosols in the air contribute to the various hues of red and orange at sunrise and sunset.
C. The concentration of aerosols is maximum in mesosphere.
D. Aerosols act as surfaces on which water vapour condenses.
Choose the correct answer from the options given below:

Correct Answer: (c) A, B and D only
Solution:

Aerosols are suspension of particles and liquid droplets. Aerosol includes sea salts, fine soil smoke pollens and soot. Airosol in the air contribute to the various hues of red and orange at sunrise and sunset. The concentration of aerosols is maximum in Troposphere.
It act as surfaces on which water vapour condenses concentration of aerosols decreases with increasing highest in atmosphere and mesosphere which extends from 50 to 80 km is too high for Aerosols to get there.

45. Which of the following statements are NOT true about Spatial Analysis?

A. The application of quantitative techniques in locational analysis is known as 'spatial analysis'.
B. It is not associated with the philosophy of positivism.
C. The generalisation arrived at with the application of spatial analysis is based on: direction, and connection.
D. It got popularity due to deterministic approach in geography.
Choose the correct answer from the options given below:

Correct Answer: (c) Band D only
Solution:

Spatial Analysis is approach of Human geography which is related to spatial organisation of geographical facts and events. The application of quantitative techniques in locational analysis is known as spatial analysis.
It is associated with the philosophy of positivism the application of spatial analysis is based on direction and connection. Berry, Marbel, Bungi, Smith and Hagget played important role in spatial analysis.
Option D is incorrect because determinism /Environmental determinism is a philosophy, which advocates that environment plays a dominant role in controlling humans' action and human's are just passive living being driven by environment.So spatial analysis did not have any relation with determinism
