61. Which of the following statements about impact of climate change on oceans are not true?

(A) The oceans have become less acidic over the past few decades.
(B) The sea surface temperature has increased during the last century
(C) Sea level has risen at the rate approximately six-tenth of an inch since 1880
(D) The oceans will store less carbon-di-oxide in the coming years.
Choose the most appropriate answer from the options given below:

Correct Answer: (d) A and D Only
Solution:

Climate change is a long term process which is influenced by Natural and Anthropogenic causes, but the pace climate change is triggered mainly by anthropogenic activities i.e. rapid extraction of minerals disturbing the chemical composition of Atmospheres, Hydrosphere and Lithosphere. Before Industrialization Anthropogenic causes played miner role in climate change. Due to Industrialization, urbanisation and over exploitation of resources climate change problem become critical.
The Sea surface temperature has increased during last century. Due to Global warming glaciers are melting. Sea level has risen at the rate approximately six tenth of an inch. The oceans will store more CO₂ in coming years which decrease percentage of oxygen in oceans. It will deteriorates Marine resources.

62. Which of the following statements are correct about Coriolis force?

(A) Coriolis force is present in all motion relative to Earth
(B) Coriolis force is maximum at equator and zero at pole.
(C) The strength of Coriolis force varies with speed of motion and also decreases with latitude
(D) The amount of deflection caused by Coriolis force varies according to rotation of earth, longitude and object.
Choose the correct answer from the options given below:

Correct Answer: (e) *
Solution:

Coriolis force is an apparent force caused by the earth's rotation responsible for deflecting winds towards the right in the northern hemisphere and towards the left in the southern hemisphere. Coriolis force is minimum at equator and maximum at poles. The strength of coriolis force varies with speed of motion and also increases with latitude. So, options (B), (C), (D) are incorrect while only option (A) is correct, i.e. None of the correct option is given.

63. Which of the following data are sources of proxy data for climate change studies?

(A) historical documents
(B) sea floor sediments
(C) satellite data
(D) fossil pollen
Choose the correct answer from the options given below:

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

Historical documents, sea floor sediments and fossil pollen data are sources for proxy data for climate change studies. Reliable data keeping of climate change on world level started in 1880s. Before record keeping proxy data was only source to study climate change.

64. Which of the following statements are correct with regard to the effects to global warming?

(A) Due to global warming it is believed that heat waves may increase in future.
(B) Tropical cyclones will be more intense
(C) It is likely that area affected by droughts will decrease
(D) The models indicate that some regions will experience significantly more precipitation and runoff
Choose the correct answer from the options given below:

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

Global warming is a Phenomenon used for to show the rising temperature of earth due to rising of green house gases in atmosphere which entraps the long wave terrestrial radiation resulted into rise temperature of earth.

Effects of Global Warming
(i) Heat wave may increase in future with climate extreme
(ii) Tropical cyclones will be more intense
(iii) Some regions will experience significantly more precipitation and runoff.
(iv) Area affected by droughts also increase.

65. Which of the following statement/s is/ are correct?

(A) The intensity and frequency of tropical cyclones is increasing but economic damage is decreasing
(B) More tropical cyclones occur in Bay of Bengal than Arabian sea
(C) The cyclonic systems developed in Pacific Ocean have impact on South-East Asia
(D) Intensification of cyclone within 5 to 22 hrs. makes prediction of its track difficult
Choose the correct answer from the options given below:

Correct Answer: (d) B, C and D Only
Solution:

More tropical cyclones occur in Bay of Bengal than Arabian sea due to more temperature than Arabian Sea. The Cyclonic system developed in pacific ocean have impact on South East Asia. Intensification of cyclone within 5 to 22 hrs. makes prediction of its track difficult.
Option (A) is incorrect because with increasing intensity of tropical cyclones, economic damage also increases because most of the developed and highly populated cities of tropics located are along sea costs and most of them are prone to tropical cyclone.
