-
They observed the Sun's position and movement to predict weather patterns.
-
They constructed water reservoirs and irrigation systems based on solar cycles.
-
All of the above
D
Correct answer
Explanation
Ancient Indian studies made significant contributions to our understanding of the Sun's influence on water resources. They developed methods for measuring solar radiation, observed the Sun's position and movement to predict weather patterns, and constructed water reservoirs and irrigation systems based on solar cycles.
What is the role of solar cycles in the construction of water reservoirs and irrigation systems?
-
Solar cycles determine the best time to build water reservoirs.
-
Solar cycles determine the best time to irrigate crops.
-
Solar cycles determine the size of water reservoirs and irrigation systems.
-
All of the above
D
Correct answer
Explanation
Solar cycles influence the amount of solar radiation reaching the Earth's surface, which in turn affects water availability. Ancient Indian astronomers used their knowledge of solar cycles to determine the best time to build water reservoirs, irrigate crops, and design irrigation systems.
