Human Hair - Facts and Information Hair is defined as a protein filament that grows through the epidermis from follicles deep within the dermis. Hair can grow on most areas of the human body, except on the palms of the hands and the soles of the feet (among other areas), but hair is most noticeable in most people in a small number of areas, which are also the ones that are most commonly trimmed, plucked, or shaved. These include the face, nose, ears, head, eyebrows, eyelashes, legs and armpits, as well as the pubic region.

Ancient astronomers observed points of light that appeared to move among the stars. They called these objects "planets," meaning wanderers, and named them after Roman deities—Jupiter, king of the gods; Mars, the god of war; Mercury, messenger of the gods; Venus, the goddes of love and beauty, and Saturn, father of Jupiter and god of agriculture.
Landscape Information It might sound daft, but knowing the type of landscape you are dealing with can be quite a challenge.

Wind Power Information, Wind Power Facts Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unevenly heats the surface of the Earth. As hot air rises, cooler air moves in to fill the void.

The Moon is similar to the Earth in that it has a crust, mantle, and core. The composition of the two bodies is similar, which is part of why scientists think the Moon may have formed from a large impact breaking off a piece of Earth when it was forming. Scientists have samples from the surface or crust of the Moon, but the composition of the inner layers is a mystery. Based on what we know about how planets and moons form, the core of the Moon is believed to be at least partly molten and probably consists primarily of iron. with some sulfur and nickel .

The core likely is small, accounting for just 1 to 2 percent of the Moon's mass.The Crust, Mantle, and Core of the Moon
The largest portion of the Moon is the mantle. This is the layer between the crust (the part we see) and the inner core. The lunar mantle is believed to consist of olivine, orthopyroxene, and clinopyroxene. The composition of the mantle is similar to that of the Earth, but the Moon may contain a higher percentage of iron.
Scientists have samples of the lunar crust and take measurements of properties of the Moon's surface.
The crust consists of 43% oxygen, 20% silicon, 19% magnesium, 10% iron, 3% calcium, 3% aluminum, and trace amounts of other elements including 0.42% chromium, 0.18% titanium, 0.12% manganese, and smaller amounts of uranium, thorium, potassium, hydrogen and other elements. These elements form a concrete-like coating called regolith. Two types of Moon rocks have been collected from the regolith: mafic plutonic and maria basalt. Both are types of igneous rocks, which formed from cooling lava.The Atmosphere of the Moon
Although it is very thin, the Moon does have an atmosphere.

The composition is not well known, but it is estimated to consist of helium, neon, hydrogen (H2 ), argon, neon, methane, ammonia, carbon dioxide. with trace amounts of oxygen, aluminum, silicon, phosphorus, sodium, and magnesium ions. Because conditions contrast sharply between day and night, the composition during the day may be somewhat different from the atmosphere at night. Even though the Moon has an atmosphere, it is too thin to breathe and includes compounds you wouldn't want in your lungs.Learn More
If you're interested in learning more about the moon and its composition, NASA's moon fact sheet is a great starting point. You may also be curious about how the moon smells (no, not like cheese) and the difference between the composition of the Earth and the Moon. From here, notice the difference between the composition of the Earth's crust and the compounds found in the atmosphere .
You might want to know these amazing Neil Armstrong facts for kids that includes his personal achievements, awards, initial career, and his remarks after coming from a historic journey.
Neil Armstrong was the first man to set foot on moon. It was the historical day of July 20, 1969 when Neil stepped out of the lunar module and walked on the moon and marked his words in the history of mankind, “One Small Step for Man, One Giant Leap for Mankind.” He was only 38 at that time.
Armstrong was born on August 5, 1930 in Wapakonita, Ohio. It was the result of several years of persistent efforts that continued in good times and bad times, or may be the outcome of a bitter competition from the feared rivals. It had to happen that day.Neil Armstrong Facts For Kids
Armstrong was always willing to fly as high as one could dream of. Finally his dream came true when, after completing his degree from Purdue, he decided to join the then National Advisory Committee for Aeronautics (NACA) which later became National Aeronautics and Space Administration (NASA). Eventually, he lived up to his inspiration but the journey did not stop.
Prominent among his achievements were those of initial flight hours which he had experienced while conducting 50 types of aircrafts. Armstrong while logging 2,450 hours also attained a speed of Mach 5.74 (4,000 mph) together with an altitude measuring at 63,198 meters (207,500 ft). He flew in the X-15 aircraft.
Technically, Armstrong was an engineer and he had a craze to become a pilot. Many non-engineering pilots condemned his flying technique by marking that Armstrong’s flying technique was too technical to do the job.
Some of his critics were Pete Knight and Chuck Yeager. They believed that flying is not all about moving sound in a mechanical manner rather it’s what you feel. One could hardly get this feeling while an engineer is flying.
It goes without saying that Armstrong was no less competent as compared to other non-engineer pilots but he was also involved in few ariel accidents.
Armstrong began studying aeronautical engineering in 1947 Purdue University while he was on Navy scholarship.
This is a picture of Neil Armstrong’s first foot on moon. Even after 45 years his step looks as fresh as it was in 1969 and it seems only yesterday he walked on the moon.
Neil Armstrong was married to Janet Shearon on January 1956. Janet initially gave birth to a son and a daughter whose names were Eric and Karen respectively. Karen however passed away because of incurable brain tumor. She died on January 1962. In the following year, the couple soon added another son to their family whose name was Mark.
In 1963, Armstrong was the first American civilian to fly in space. Earlier in 1957, he was picked for the MISS (Man In Space Soonest) mission.
On March 16 1966, Armstrong was sent on Gemini 8 mission. In the mission, Neil served as a Command Pilot and the crew was supposed to finish the first ever docking with the other unmanned Agena spacecraft. However, they couldn’t complete the ‘extra-vernacular activity’ even though they managed to dock with the craft after 6.5 hours. This had never taken place in the history before that the two vehicles successfully docked in space.
Armstrong was also deemed to be the only person to communicate directly with the astronauts on mission. He served as a CAPCOM for Gemini 11.
He served as the commander of the back-up crew of the Apollo program (Apollo 8).
Neil Armstrong was never going to set a first foot on the moon in fact one of his colleagues Buzz Aldrin was deemed to do this job in the start. However, the positions of astronauts in the module became complicated and Aldrin could only reach the hatch by crawling over Armstrong. So the plan was changed and finally it was decided that Armstrong would be the one to step out of module (upon landing) and make history.
People gave three astronauts a warm welcome when they returned to earth on July 24, 1969. Crowds all over the streets of New York were anxiously waiting to see this historic moment of their famous heroes. Consequently, Armstrong won many awards such as the Congressional Space Medal of Honor and a Medal of Freedom.
Armstrong underwent severe blocked coronary arteries as a result of which he had to go through bypass surgery on August 7, 2012. However he couldn’t held any longer and he passed away on August 25, 2012 in Ohio when the surgery caused several complications. On the eve of his death, White House pronounced Armstrong as ‘one of the greatest American heroes of all time’.
The Sun always illuminates half of the Moon, but varying amounts of the sunlit part are visible
Encyclopædia Britannica, Inc. Photos Yerkes Observatory, University of Chicago
The angle between the Sun and the Moon in the sky determines what fraction of the side of the Moon facing Earth is lit, giving rise to the succession of phases. The phase cycle is often considered to start with the new Moon, which is invisible from Earth. In this phase the Moon is almost or directly between Earth and the Sun, so the entire sunlit portion of the Moon faces away from Earth. The Moon's orbit carries it eastward relative to the Sun in the sky, so that a few days after new, the Moon appears in the early evening as a crescent, with the lit side facing west, toward where the Sun has just set. The rest of the Moon's disk may be faintly visible from light reflected off Earth. This crescent Moon sets a few hours after the Sun.
The changing appearance of the Moon during the lunar cycle depends on how the Moon is positioned in
Encyclopædia Britannica, Inc.
About a week after new, the Moon appears half lit and high in the sky, 90 degrees east of the Sun, at sunset. This Moon, called first quarter (being a quarter of the way through its monthly cycle), will have risen at about noon and may have been visible in a blue sky during the afternoon. For the next few nights, the Moon comes up later in the afternoon and continues to wax, or show a greater illuminated fraction. During this time it is referred to as gibbous, or between half and full. About two weeks after new, it rises as a full Moon more or less in the eastopposite the Sunat sunset. The full Moon stays up all night, setting more or less in the west at about sunrise.
The phases of the Moon can be identified from the fraction of the Moon's near side that is
Encyclopædia Britannica, Inc.; source: U.S. Naval Observatory
After its full phase, the Moon rises later and later each evening, passing through waning (progressively less illuminated) gibbous phases. Then, at third quarter, it appears as a half Moon with its eastern half lit. In this phase, the Moon rises at about midnight, is highest at sunrise, and sets at about noon. Finally, after a few days of waning crescents, the Moon returns to new, 29.53 days after the last new Moon. Actually, the Moon orbits Earth with a period of 27.32 days, but during this time Earth will have moved almost 1 /12 of the way around the Sun, so 2.21 extra days are needed for the Moon to get back to its position between Earth and the Sun.
It is worth noting that the Moon's lit part always faces the Sun, since it is the Sun that provides the light. This means that at night the lit part of the Moon must always face somewhat downward (often tilted at some angle), since the Sun is down. Many depictions of the Moon in art and movies have shown impossible orientations, such as the horns of a crescent Moon pointing sideways at night; they would have to point upward somewhat.
