Welcome to Life Noggin.
The subscribe button and the bell button are getting to a fight again
Guys you both have things you got to work out, ok?
Everyone has their favorite season
On the internet, people will even fight you over it
But what if there was only one season?
Seasons are the result of the Earth’s tilt
The axis – or the imaginary line through the north and south poles that our planet spins around
isn’t straight up and down.
It’s actually tilted in about a 23.5-degree angle
As the Earth makes its journey around the sun
which represents one year
this axis always points in the same direction
That’s why, throughout the year
different parts of the Earth are in a direct view of the sun
Scientists think the tilt was caused when the Earth was hit
by a Mars-sized object named Theia
shortly after the Earth was formed
This theory, called the Giant Impact Hypothesis
is thought to also be how the moon was formed
So what if the entire planet experienced only one season?
Well, instead of cycling between hot and cold weather
average temperatures would remain constant
This would have a big effect on plants and animals
and in turn, a huge impact on humans as well
There actually has sort of been an example of this over 200 years ago due to a volcanic eruption
When a volcano erupts, it releases dust, ash
and sulfur into the atmosphere
that could block solar rays and actually cool the planet
These effects can last from months to years
The largest known eruption occurred in 1815
when Indonesia’s Mount Tambora released
so many particles into the air
that it darkened the sky
and affected the climate for months
In fact, due to this event
in the summer of 1816 New England and Europe experienced frost
snow, and ice storms throughout the summer months
都在经历霜冻 下雪 以及冰暴
This was later dubbed the “Year Without a Summer.”
But would an endless winter really be so bad?
Think about all the skiing, or sledding or hot cocoa drinking you could do
想想看你可以滑雪 坐雪橇 还可以喝热可可
Well, if you happen to enjoy eating as I do
I have some bad news
While some very important crops, like wheat
various vegetables, and some fruit trees
require a period of cold to stimulate growth
they won’t sprout until after it warms up
So without spring and summer
it would be nearly impossible to grow any produce or grains
作物 谷物 还有其他相关的植物
or any other plant for that matter
During the Year Without a Summer
many crops died from the frost and lack of sunshine
resulting in famine and poverty due to skyrocketing food prices
The cold temperatures also killed many animals, from sheep to birds
And without spring
you can forget any new animals being born
Most species time their mating behaviors
to produce offspring in warmer months
when there are lots of food sources
So it turns out that getting hit by that big rock
was the best thing to happen to our planet
Without that tilt and our four seasons
life here would be pretty difficult
Hopefully this will make you enjoy your summer vacation even more
if you have one!
So what season is your favorite
Let me know the reason in the comment section below
and be civil about it, ok guys
Curious to know what would happen if you never left the pool?
Check out this video
One of the first things you’d experience is
some really, really wrinkled fingers and toes
This feature actually gives you improved grip
on objects underwater
It’s thought that this extreme constriction
of blood vessels was an evolutionary advantage for humans
As always my name is Blocko!
