5 points Extra Credit: Do not ask your teacher to explain or elaborate. This is only an extra credit. It is your
choice to answer it or not! Do not answer it if you are not willing to think.
The sun’s gravity is 179X stronger than that of the moon. What is tide? Explain or illustrate why the moon has
more influence on earth’s tides.

The moon, which is approximately 240,000 miles (386,240 km) from the earth, exerts a
greater influence on the tides then does the sun, which sits 93 million miles (150 million km)
from the earth. The strength of the sun's gravity is 179 times that of the moon's but the moon
is responsible for 56% of the earth's tidal energy while the sun claims responsibility for a
mere 44% (due to the moon's proximity but the sun's much larger size).
