WHY is the Moon sometimes orange?
The rays of sunlight are known to include all existing colors. The Moon reflects sunlight and redirects it to Earth. But light still needs to break through our atmosphere before it can reach human eyes.
On its way to Earth's surface, sunlight is able to refract gases in the atmosphere, causing us to see the Moon in red, orange, or some other color when we look through a prism of sorts.

WHY was it better before and what are the reasons?
Psychologists call it the duckling syndrome. When a duckling hatches from an egg, the first thing it sees is its mother. But if she is not there, it takes for its mother what is near him.
This is also the case with man. When he encounters a new field of study when he is young, then he begins to think of that object as the best. This is how we always remember our first love, adore old computer toys, watch ancient movies from our childhood, enjoy old things and clothes.

WHY does the Moon always face one side of the Earth?
Many people mistakenly assume that the Moon, unlike the Earth, does not rotate on its axis. This is fundamentally incorrect statement, since the Moon also performs similar rotations.
The thing is that the rotation of the Moon around its axis has such a character of speed, that during the rotation around the Earth, the motion of our natural satellite is synchronized and leads to the fact that the space body is always turned by the same side to the surface of our planet. Overall, we are able to observe about 59 percent of the lunar surface.

WHY do cats sleep on people?
It's all about human body temperature and a cat's affinity for its owner.
There is no doubt that cats are highly fond of sleeping on something warm, and compared to the objects around them, it is the human that radiates the most warmth, which makes it the ideal option for their pet to sleep.

WHY does beer make the belly grow?
The consequences of drinking beer are negative for men. When drinking this heady drink frequently, the content of estrogen (the female hormone) in the male body increases.
It contributes to the accumulation of excess blubber, which results in the formation of the so-called "beer belly".
It also leads to a serious hormonal failure, which spoils the figure and worsens men's health.

WHY is the swamp gurgling?
If you've ever observed a swamp, you may have noticed that bubbles are constantly rising to the surface. This is marsh gas coming out of the silt.
It is produced by the decomposition of plant debris under the influence of bacteria without access to air.
This gas is colorless and odorless. It is also heavier than air and highly explosive❗️

WHY is it hard to breathe in the mountains?
When move away from the earth's surface, the density of air decreases. This is due to the pressure in the upper atmosphere is lower than on the ground.
The lower layers of air are under more pressure than the upper layers.
This means that such thin air contains fewer molecules, including oxygen molecules.

WHY do dogs dig holes?
It is worth noting that dogs were not always pets. And when they were wild animals, digging holes was in their blood.
It is these instincts that pets are periodically reminded of even today, which leads to an irresistible desire to dig a hole.
Oftentimes, dogs dig holes on hot summer days. They remove the top layer of soil in order to get to the cooler one and comfortably settle down there.

WHY does the water in a river never run out?
Water in rivers travels along their course all the way to where it flows into other rivers, lakes, seas, or oceans.
Water from seas and oceans evaporates and by condensation in clouds falls as precipitation. This can be not only rain, but also snow or ice.
Rainwater can either flow directly into rivers or into rocks that gradually make their way into rivers.

WHY do hands get numb at night?
Such a phenomenon can occur since a person lays down with his entire weight on his arm while sleeping and impedes blood flow. Thus, the limbs are not fully saturated with oxygen, which leads to numbness.
In addition, diseases such as hypovitaminosis B, osteochondrosis or circulatory disorders can also affect hand numbness at night. In such cases, it is definitely the right thing to do is to see a doctor.

WHY shouldn't alkaline or acidic solutions be stored in aluminum cookware?
The reason is that aluminum reacts with alkalis. During this reaction, aluminum vapor is released, as well as alkali, which adversely affects human health and well-being.
The reason is also that alkalis corrode aluminum.
Of course, in a single use of aluminum cookware for such solutions, you will not see a hole in its bottom. However, if such a rule is violated systematically, the cookware can be thrown out very soon.

WHY are the rocks moving in Death Valley?
Moving rocks are also called sliding, or crawling rocks, a geological phenomenon discovered at the dried-up Lake Racetrack Playa in Death Valley, USA.
The main factor is the rather slippery base beneath the rock, as well as the wind that nudges the rocks lying on the slimy clay.

WHY does a mosquito bite itch?
It's all about the proteins contained in the saliva of a mosquito, the first bite does not bother the immune system, but the subsequent causes a violent response in the form of red permanent itchy spots.
After a certain number of bites, the immune system stops overreacting to foreign proteins and the bite sites cease to bother.
As it turns out, humans are not really adored by mosquitoes. Buffalo or rat blood, owing to the amino acid isoleucine, is more beloved by mosquitoes.

WHY does hair burn out in the sun?
Hair consists of multiple substances and microelements, including melanin, a natural pigment responsible for the dark shade of hair as well as skin and retina.
Yet melanin has its "weak side": when exposed to the sun, it begins to disintegrate, but only if it is part of the hair, which subsequently turns lighter – burn out.
On the contrary, our skin, exposed to the UV rays, produces more melanin, since the body's defense mechanism is activated.

WHY do leopards hide their prey in a tree?
Despite their strength, speed and ferocity, leopards have to protect their prey from many savanna creatures.
Lions, hyenas, hyena dogs and other predators are likely to be among the eaters of prey. Thus, leopards conceal their prey in a tree. It literally climbs to such a height with the carcass in its teeth.
At first glance it may seem strange that the leopard is afraid of anyone. However, it is worth considering that this predator does not live in a pack.

WHY is the woodpecker called the forest doctor?
The woodpecker is able to detect under the bark of which tree pests are hiding.
Once the woodpecker figures out which tree is inhabited by insects, it immediately starts its work. It chisels the tree until there is a hole in it, through which it can extract the pests.
Also, the woodpecker helps other animals by pecking nests in trees, thereby "donating" housing to other birds.

WHY is the Sun called a star and not a planet?
The surface temperature of the Sun is thousands of times that of the Earth and many other planets in our Solar System, indicating that it is a star.
The planets feature a chemical composition whereby they are formed not only of light particles, but also of solid elements. Stars, in turn, are mostly formed from light particles, just like the Sun itself.
On the surface of the Sun, all sorts of nuclear reactions are constantly taking place that are not typical of planets in such quantity and scale.

WHY shouldn't we store gasoline in plastic containers?
Many people who have heard of this unspoken rule believe that gasoline should not be stored in plastic containers since it may corrode the walls. However, that's not the case.
Gasoline cannot be stored in plastic as it produces gasoline vapors.
And the plastic itself is much more susceptible to becoming electrified than metal canisters.
That is why if filling plastic containers with gasoline, you run the risk of ending up with an explosion.
