What factor limits the number of eclipses per year
labwork [276]

Answer:

"Option B. The tilt of the moon´s orbit around the earth " limits the number of eclipses per year

<u>Explanation</u>:

The moon's orbit is tilted only by 50^{\circ}. Around the sun when the earth and moon move, the tilt of the moon changes according to the direction of the sun. When the same thing occurs to the earth, the seasonal changes occur. The theory is all related to moon's formation. Due to this tilt the moon's road near the stars changes slightly in every month. The inclination is with respect to the ecliptic plane. If this inclination was absent then we could have felt the eclipse more frequently.
