Question

explain how the Earth revolution and leap year are linked​

Answer 1

Answer:

Every 365 1/4 days (not exactly 365 days), the Earth returns to the same exact spot in its orbit. That is why we have a leap year roughly every 4 years, to synchronize the seasons with our calendar; if we had a 365-day calendar every year, the seasons would drift around the calendar.

Answer 2

Actually 1 revolution takes 365 1/4 days to complete 1 year so we know leap comes every 4 years we know that, with an extra day in February so 4 years we have 1 day extra as 1/4+1/4+1/4+1/4= 4/4= 1

so revolution and leap year are related to one another
