An eclipse once
stopped a 15-year war
in the middle of a
battle. Both armies put
down their weapons
and signed peace right
there.
In 2017, Donald Trump
stood on the White
House balcony and
stared straight at a
solar eclipse, even
though his own staff
told him not to.
Earth is closer to the
Sun in summer, and
that's why summer is
hotter.

WHY DO WE HAVE SEASONS?
Hands up for the option you think is correct.
A
Earth is closer to the Sun in summer.
B
The Sun is hotter in summer.
C
Earth is tilted, so sunlight hits us at a different angle.
D
The Sun moves closer to us in summer.
Eclipses are about
LINING UP.
Seasons are about
TILTING.
