Why are solar eclipses rarer than lunar eclipses? Mark all that apply.

• Because solar eclipses can only happen in the 1st quarter moon position in the spring.

• Because not every location on Earth sees the total solar eclipse.

• Because the moon's shadow is smaller than the Earth.

• Because lunar eclipses happen every month.

The definition of eclipse is:

• The planets line up
• The Sun, Earth and Mars line up
• The Sun, Earth and Moon line up
• The Earth, Moon and Venus line up 

A lunar eclipse occurs when the line up is this:

• Sun -Earth-Moon
• Moon, Sun, Earth
• Earth-Sun-Moon
• Sun-Moon-Earth
