why do we have different moon phases

why do we have different moon phases

I am a mother of three young children (12, 7 and 6) who have asked me the question, "Why does the moon have different faces (said the 6 yr old) phases (said the 12 year old). I can usually find an answer to appease their cornucopia of questions, however, this one stumped me. The question as I've deciphered it is why or how does the moon show on earth as a half-moon, 1/4 moon, or "smiley face" moon. And of course my oldest wants to know what covers it (if anything). I am not astronomically (? ) inclined, so I don't even know if I have worded this question properly. The question is worded just fine! I hope that I can explain the answer well enough. Nothing is covering the Moon, part of it is just not illuminated as it is facing away from the Sun. There is a neat little practical

 why do people say god bless you after you sneeze

why do people say god bless you after you sneeze

Why do we say "bless you" when someone sneezes? THIS goes back to more superstitious times when a sneeze was believed to separate the soul from the body. To prevent the devil stealing the soul the incantation "bless you" (i. e. God bless you) was uttered to release the soul from Satan's clutches and return it to its rightful owner. IT COMES from the time of the Great Plague. As sneezing was one of the first symptoms, and it was obvious that person would die, "bless you" (or "God bless you") was a suitable thing to say. IT WAS believed that sneezing was the way for the body to rid itself of the devil's evil influences. The act of blessing a person subsequent to a sneeze was meant to act as a safeguard against the devil's evil influences returning. However, if the sneezer should thank the

 why was great britain the first country to industrialize

why was great britain the first country to industrialize

In the 18th century, new technologies allowed Britain to produce more agriculture than ever before. Other advances, like more efficient rotating of crops, helped spur production. A greater percentage of land was also used for production. In 1700, about 20 percent of England's arable land was fallow, but this fell to just 4 percent by 1871. Cereal yields were also increased by the discovery of nitrogen, which was a critical fertilizer. All of this production fueled a growing population, with England's rising from 5. 7 million in 1750 to 16. 6 million a century later. Many people moved to cities, fueled urbanization and contributed needed labor for the Industrial Revolution. Extracts from this document. Why was Britain the First Industrial Nation? From 1780 for just over a century Britain

 why do some dogs have dew claws

why do some dogs have dew claws

almost always have dewclaws on the inside of the front legs and occasionally also on the hind legs. Unlike front dewclaws, rear dewclaws tend to have little bone or muscle structure in most breeds. It is normal, although not biologically necessary, that certain breeds will have more than one dewclaw on the same paw. At least one of these dewclaws will be poorly connected to the leg, and in this case it is often surgically removed [. When a dog has extra dewclaws in addition to the usual one on each front leg, the dog is said to be double dewclawed. There is some debate about whether a dewclaw helps dogs to gain traction when they run because in some dogs, the dewclaw makes contact when they are running and the on the dewclaw often wears down in the same way that the nails on their other

Truth of the day: the holidays just wouldnБt be Бthe holidaysБ without people working together to uphold its oh-so merry traditions.

The short answer is to spread joy, of course, but there is a long answer that corresponds to some of the more bizarre holiday traditions, too. Today, we are going to address what is quite possibly the most familiar, yet most perplexing one of allБhanging Christmas lights. Like modern-day

 why do the tutsi and hutus fight

why do the tutsi and hutus fight

Hutu and Tutsi are two groups in Africa that became known to most in other parts of the world through the grisly 1994 Rwanda genocide, but the history of conflict between the two ethnic groups reaches back further than that. Generally, the Hutu-Tutsi strife stems from class warfare, with the Tutsis perceived to have greater wealth and social status (as well as favoring cattle ranching over what is seen as the ). The Tutsis are thought to have originally come from and arrived after the Hutu came from Chad. Burundi, 1972 The seeds of resentment for the minority Tutsis were sown when the first elections after winning independence in May 1965 saw strong Hutu wins, but the king appointed a Tutsi friend prime minister, sparking a failed coup attempt by Hutus. Even though this was quickly

 why do my teeth hurt when i floss

why do my teeth hurt when i floss

By no stretch is it rare for your gums to hurt during and after flossing. Even some bleeding is to be expected. This is especially true if you have not flossed in a long time. However, if your gums do indeed hurt when you floss, and unbearably so, there are some things you can do. Be Gentle Perhaps the most obvious way to combat gum soreness and bleeding is to be gentle. One of the most common occurrences of these gum problems is over-aggressive flossing. In other words, if you are too rough on your gums while flossing, either because you are out of practice or because you are in a hurry, soreness and hurting is to be expected. Instead, try taking your time and be gentle. Also, if you are just starting out, be patient and consistent, your gums will become more conditioned over time. Use

 why do the lights in my house flicker

why do the lights in my house flicker

Flickering lights in your home are a normal occurrence. In fact, the cause of flickering lights is usually benign. However, there are some instances in which this could be a symptom of a major electrical problem in your home, so it is important you know the differences between major and minor lighting issues. All wires have a level natural resistance, meaning that when electric current flows through them, some amount of voltage gets used to force the current flow against the wire's resistance. This means that when the current reaches it's destination, there is less voltage for your various loads (lights, toaster, etc. ). If you have loads that turn on and off, like lights, then the voltage supplying your lights will change, and a flicker will occur. Many loads have inrush current, which

 why do you get scabs on your scalp

why do you get scabs on your scalp

I have sores and bleeding scabs on my scalp that are itchy and irritating. They have been present for many years now. Sometimes I have a lot of them and at times only one or two. The skin around them on my scalp is also flaky and scaly in texture although I would not say it was, just dry. I have been embarrassed to see my GP about this. I hoped that it would get rid of itself, but after 10 years I realise that it is not going away. Any advice would be welcome. There are many skin conditions that can affect the scalp and of course any changes that occur are very noticeable because you cannot easily cover them up. But you have no need to be embarrassed and it's very likely you will easily find a treatment which will quickly sort this out. ...
