Earth's shadow and eclipses
Question:

m.
Choose the correct answer.
1.
If a solar eclipse needs a new Moon and a lunar eclipse needs a full Moon, why don’t we see eclipses every month?
The Moon stops orbiting Earth occasionally
Earth rotates too quickly for eclipses to form
The Moon’s orbit is slightly tilted, so the alignment does not happen every month
The Sun and Moon are not bright enough to form shadows each month
2.
A lunar eclipse can occur only when
Earth is between the Sun and the Moon, and all three are perfectly aligned
The Moon is at its closest distance to Earth
The Moon is between Earth and the Sun
The Moon’s orbit is tilted away from Earth’s orbit
