10 Ridiculously Cool Natural Phenomena
Natural phenomena are events that occur in nature because of natural
reasons. They are not controlled or caused to happen by humans but are
rather bound to happen. Volcanic eruption is one example of a natural
phenomena.
A lot of what we see in the natural world is taken for granted. Sure, we
may marvel at the occasional sunset, or check out some neat clouds
every once in a while, but for the most part, the amazingness of the
world around us tends to go unnoticed. And that’s a shame, because if
you know where to look, you’ll see that nature can do things way more
impressive than sunsets or clouds. For example:
1. Frost Flowers
To put it simply, frost flowers
are flowers made of frost. More accurately, frost flowers are nothing
like that, so let’s put it technically instead: they’re buildups of ice
particles around the base of certain plants and types of wood. When the
temperature outside the plant is below freezing and the temperature
within them is not, then water is pulled to the surface in a process
similar to transpiration. This leads to a fragile chain of ice being
pushed outward, which ends up forming sprawling, delicate formations. So
they’re not exactly flowers—more like leaves, if anything—but they’re
just as pretty to look at, and at least twice as cool.
2. Columnar Basalt
At some point in time, basalt looked at itself in the mirror and
realized that if it ever wanted to be noticed by the cool kids in nature
(us), it would have to step up its game. And so, much like the
unpopular girl who is secretly gorgeous when she takes her glasses off,
basalt showed the world what it was capable of—by arranging itself into
columns.
Admittedly, on the surface this doesn’t seem all that
impressive—columns aren’t traditionally very exciting—but when put
together into a sprawling honeycomb, this type of basalt is a sight to
behold. The unique formations are a result of lava flows cracking as
they cool, in a perpendicular direction to the original flow. Columnar basalt clusters can be found all over the world—and then, naturally, climbed.
3. Snow Donuts
You know how when you were a kid, and it snowed outside, the first
thing you did was roll up a nice big snowball? You either threw it at
somebody’s face or made a snowman with it (depending on what type of kid
you were), but that’s not the important part of the memory right now.
The important thing—the fantastic thing—is that nature has its own way
of rolling snowballs: snow donuts.
These rare shapes are formed—under perfect temperature conditions
only—when a mass of snow either falls or is blown by the wind. If it
manages to catch on to some other snow, and gravity or the wind is in
its favor, then the new snowball will roll itself in the exact same way
we all used to. In this case, though, the middles tend to collapse to
create a donut shape, which can end up as tall as 26 inches (66
centimeters).
4. Waterspouts
Waterspouts
are exactly what they look like, and exactly as awesome as they sound:
they’re tornadoes that form over water. Because of this, they don’t pose
a major threat unless you happen to be in a boat—but if you are, then
watch out, because these things can achieve speeds of up to 190 miles
(305 kilometers) per hour. In fact, it’s been speculated that many
mysterious shipwrecks—such as those within the Bermuda Triangle—are
simply a result of bad luck with waterspouts. They can occur anywhere
over water, but are especially prevalent in the Florida Keys, where
there can be 400 or 500 waterspouts a year.
5. Sun Dogs
Here’s another phenomenon that has to do with ice crystals in the atmosphere. Like fire rainbows, sun dogs
are massive halos in the sky as a result of light refraction—though in
this case, they appear to actually encircle the sun. Sun dogs can be
recognized by the two distinctive bright spots on either side of the
halo—if these blips are bright enough, it can even look like there are
three suns in the sky, all side by side. And the good news is that this
happens all the time, all over the world, so you’ll be able to start
seeing them if you look closely enough (especially when the sun is low
in the sky). Just remember that if you look closely enough at the sun
for too long, you won’t be able to see much of anything. Ever. So try to
be careful.
6. Fire Rainbows
These colorful offshoots can often be seen during the summers of
middle-latitude areas, such as most of the United States. What they
actually are is a large halo of refracted light, and despite their
nickname, they have nothing to do with either fire or rainbows. They
only occur when the sun is at least 58 degrees above the horizon, when
there are cirrus clouds in the sky that are filled with plate-shaped ice
crystals. The refraction of light is always parallel to the horizon,
and because the arcs are so big, only sections of them are ever commonly
seen—which is why it can look like certain patches of cloud are on fire
(or throwing a rave). The proper name for these things, in case you
ever need to impress a scientist, is ‘circumhorizontal arc.’
7. Supercells
If Superman is basically a stronger, more flight-enabled version of a
regular man, then a supercell is basically a stronger, more
tornado-enabled version of a regular storm cell. This is because—much
like tornadoes—supercells
have the tendency to spin around a lot, but also—and more
importantly—because supercells can actually create tornadoes. If you
remember one thing after reading this article, let it be this: stay the
hell away from things that can do that.
In case it needed to be mentioned, supercells are the most dangerous
of the four major storm types, in addition to being the scariest to look
at. Thankfully, they’re also the most rare, and tend to be confined to
the central United States during the springtime. If you ever happen to
come across one, wherever you are, just remember the advice you got in
the last paragraph: move in the other direction.
8. Penitentes
Here’s another cool ice formation, about as far away from underwater
as you can get—high in the mountains. These spiky fields of ice are
called penitentes,
and each individual shard can be up to a whopping 13 feet (4 meters)
high. These intimidating snow structures are formed in high-altitude
areas with low humidity, such as the glaciers of the Andes mountains. If
the conditions are right, the sun’s rays are so hot that they can
actually sublimate fields of snow—meaning that the frozen water
vaporizes without ever becoming a liquid. This leads to slight pockets
in the ice, which—thanks to their shape—actually end up attracting even
more heat. The sharp spikes, then, are just the lucky parts of the
snowfield that the sun didn’t target for complete and utter
annihilation.
9. Brinicles
When the surface of the sea freezes—such as around the north and
south poles—it does so in a way that forces pockets of especially cold
and salty seawater to gather on the underside of the ice. This mixture
of brine is denser than the seawater below it, and as a result it tends
to slowly sink to the bottom. Now, because it’s so cold, the fresher
water below the brine actually freezes around it as it falls, which
results in a giant icicle under the surface. The technical name for this
sort of thing is ‘ice stalactite,’
but what kind of boring title is that for such a breathtaking
phenomenon? Hence the need for their cool nickname, ‘brinicles.’ Regular
English didn’t have a good enough word, so we had to come up with a
whole new one (or, more accurately, sloppily mash together two old
ones).
10. Volcanic Lightning
If someone asked you to name the two coolest things you could ever
see in nature, your answer would be “volcanoes and lightning.” Or
possibly “lightning and volcanoes,” I guess, but those are the only two
options—it’s just a fact. But nature, it seems, is constantly looking
for new ways to impress us—which is why it went ahead and made volcanic lightning a reality.
And yes, it’s exactly what it sounds like—a lightning storm that
takes place in the middle of a volcanic eruption. Scientists aren’t 100%
sure why this happens, but the primary theory goes that when a volcano
erupts, it projects positively-charged debris into the atmosphere. These
charges then react with negative charges already present, which results
in 1) a bolt of lightning, and 2) a really cool picture.
