Did You Know?
Hail isn't always round or small
enough to hold in the palm of your hand.Some
of these hard chunks of ice are elongated or jagged.
They are mostly the size of gumballs, golf balls, or
even baseballs. But the largest hailstone ever recorded
in the United States landed in Coffeyville, Kansas,
in 1970. Measuring 17.3 inches (44 cm) around, this
monster ice crystal weighed 1.67 pounds (.76 kg). The
National Center for Atmospheric Research held on to
it and made models. Imagine what it would have felt
like to be hit on the head with that hailstone!
Hurricanes almost never occur
in Europe.In fact, there was no word for hurricane
in English until Europeans settled in the Caribbean
Islands. The Spanish took the name of a storm god, Huracán,
from the Taino Indians. These storms are also known
as typhoons, cyclones, and severe cyclonic storms when
they occur in other oceans.
Lightning does strike more than
once, even when it comes to people.Your chances
of being hit by lightning are very low. Some estimates
put the odds at 1 in 350,000. Others at 1 in 600,000.
Roy C. Sullivan, a park ranger, is the only person known
to have been struck by lightning seven times. He survived
each time, but not unscathed. He lost a toenail, had
his eyebrows burned off and his hair seared twice, and
even suffered shoulder and leg burns.
With dry ice and a plane, you
can create a rainstorm.Here's how cloud seeding,
or making rain artificially, works: A plane drops crushed
dry ice into a cloud; the dry ice attracts water droplets
and ice crystals; these crystals get bigger and heavier
until they fall to Earth as rain. But not everyone agrees
on how useful and fair it is to use this process. Some
argue that it only slightly increases the rain that
would have fallen anyway and that it can steal rain
away from other areas.
