The question asks for the date on which World Water Day is celebrated. This is a factual question related to important international observances.
Correct Option: D) March 22 is the internationally recognized date for World Water Day, as declared by the United Nations.
The question asks which of the given statements would significantly reduce navigation time and distance between India and East Asia. We need to evaluate each statement based on geographical knowledge and its potential impact on shipping routes.
B) 2 only. Opening a new canal across the Kra Isthmus would create a direct shortcut between the Indian Ocean and the Pacific Ocean, bypassing the Malacca Strait. This would substantially reduce the distance and navigation time for ships traveling between India and East Asia.
The question asks for the most convincing explanation for India's early cultural and trade links with Southeast Asia across the Bay of Bengal. We need to evaluate each option based on historical and geographical facts.
C) Monsoon winds across the Bay of Bengal facilitated sea voyages
This is the most convincing explanation. The predictable pattern of monsoon winds (southwest monsoon blowing towards Southeast Asia from India, and northeast monsoon blowing back towards India from Southeast Asia) was crucial for ancient and medieval sailors. These winds provided a natural, reliable, and efficient means of propulsion for sailing vessels, making long-distance voyages across the Bay of Bengal feasible and regular. This geographical factor was fundamental to establishing and maintaining trade and cultural links.
The question asks to identify the phenomenon where water alternately rises and falls over a short period. We need to evaluate each option to see which one accurately describes this characteristic.
A) Waves. Waves are defined as the rhythmic rising and falling of the ocean's surface. This phenomenon is exactly what is described in the question.
The question asks to identify the conditions under which the most important fishing grounds of the world are found. This requires knowledge of oceanography and marine biology principles that support high marine productivity.
C) warm and cold oceanic currents meet. This condition leads to upwelling of nutrient-rich waters, fostering high plankton growth and supporting abundant fish populations, making them ideal fishing grounds.
The question asks about the distribution of freshwater on Earth, specifically focusing on the largest proportion of freshwater *remaining* after accounting for ice caps and glaciers. This requires knowledge of global water distribution statistics.
C) exists as groundwater
Groundwater represents the largest proportion of accessible freshwater on Earth, after ice caps and glaciers. It accounts for approximately 30.1% of the total freshwater, making it significantly more abundant than surface water (lakes and rivers) or atmospheric moisture.
