D560 km and 580 km
Answer:
C. 580 km and 590 km
Read Explanation:
Correct Answer: Option D - 560 km and 580 km
According to official government records, Kerala's coastline is approximately 560 km long. This is the figure used in most official documents and reports. However, there are alternate measurements that place the coastline at around 580 km. This difference in measurement can be attributed to different measuring techniques, inclusion or exclusion of certain coastal features, and changes due to coastal erosion or accretion over time.
The discrepancy in coastline measurements is common worldwide and is sometimes referred to as the "coastline paradox," where the measured length of a coastline depends on the scale at which it is measured – the more detailed the measurement, the longer the coastline appears.
Other important facts about Kerala's coastline:
It runs from Kasaragod in the north to Thiruvananthapuram in the south
It constitutes about 7.5% of India's total coastline
Kannur district has the longest coastline among Kerala's districts
The coastline features numerous beaches, backwaters, and estuaries that are important for tourism and fishing industries
