SUMMARY
The Earth is experiencing a gradual slowdown in its rotation primarily due to tidal friction caused by the Moon, resulting in longer days. This phenomenon leads to a decrease in the number of days per year. Additionally, the Earth's distance from the Sun is increasing, which affects the length of the year, although this change occurs at a much slower rate. Both factors contribute to the overall perception of the Earth "slowing down."
