3. One complete revolution of Earth
around the sun takes about…
365.25 days. What happens to the ¼ day? Every 4
years we have a leap year that gives an extra day in
February.
4. What happens During a total lunar
eclipse?
The moon moves into Earth’s shadow.
5. The times when day and night are
of equal length are called
EQUINOX……. Spring and fall have
____________________.similar
temperatures because they produce similar hours
of daylight.
6. Explain why spring tides are higher
than all other tides.
Spring tides are higher than other tides because of
the COMBINED gravitational pull of the Moon and
Sun working together when they are lined up.
7. For a solar eclipse to occur…
As seen from the Earth, a solar eclipse occurs when the Moon passes between the Sun and
Earth, and the Moon fully or partially blocks the Sun. This can happen only at new moon, when
the Sun and the Moon are in conjunction as seen from Earth. In a total eclipse, the disk of the
Sun is fully obscured by the Moon. In partial and annular eclipses only part of the Sun is
obscured.
ALWAYS wear
SPECIAL eye
protection designed
specifically for
looking at the sun if
you plan on looking

eclipse. Looking at
the sun
un/underprotected
