We all have questions about the world around us. Here are some frequently asked questions and answers today.
Why is the sky blue?
'The blue color is the sky from Rayleigh scattering. As light moves through the atmosphere that most of the wavelengths longer go straight. Tiny red, orange and yellow light is affected by the air.
"However, most of the light of shorter wavelength is absorbed by gas molecules. Absorbs blue light emitted will bedifferent directions. And 'all over the sky. No matter which way you look, some of these blue diffused light reaches you. Because you see the blue light from all sides on his head, sees the sky is blue. "

Why does the sun appear larger in the morning and evening?
"We know that when a light shines through whatever means half full, it seems bigger, or better, no more a" reflection "in a givenDistance, as if seen through a half lighter. This is even more remarkable when the aqueous solution of particles or vapors can be kept as a wet and foggy. Can anyone be satisfied with this street lamp position within a few meters from a common and often noticed the size of the flame to go the distance that light or 'false', the atmosphere seems much bigger.
"This may have noticed, are more or lessall times, but when the air is humid and vapory is most intense. It 'obvious that at sunrise and sunset, the sunlight through a length greater than atmospheric air as the afternoon light, near where the air near the Earth is both denser and holds the particles in aqueous solution the top layers, the last of the sun at noon, and then the light must be extended or enlarged, and color. ... As the sun comes out from the meridian, about aflat surface, the light, since it affects the atmosphere is a larger disk. "
Tip: Take a shine and light pen on a table. First stop just above the surface as the noon day sun. Make sure that the circle is the radius of a certain size. Now the light shine on the surface at an angle, as if the sun goes down. Note the size of the light on the table. It's bigger? The plan is like the atmosphere above the earth. Light falling into a corner and makes abigger picture is. We see the object (the sun), although it is not. (See a better explanation in this regard, they are authorized to display images.

How deep is the sea?
Depends on where you bathe. Some joke, eh?
"The average depth of the oceans is about five times the average height of the earth. Generally, the continents stand about three miles above the seabed. According to the NationalAtlas, the deepest known ocean measures 10,924 meters (35,839 feet), near Guam, Marianas Trench. If the world's highest mountain, Mount Everest goods (29,141 feet), are placed in the trench of about 1.25 miles would be covered by water. "

What is the Big Bang theory?
The theory is that the universe was created or formed in the space-time singularity of extreme density and energy. Dark energy is detected at microwave frequencies, a test for an issue of greatEnergy. (The universe was everywhere at once out of nowhere as a contact I had with those who know best.) The center of the universe does not exist and can not be determined. So they say. The theory can never be proved. Read the reference for a brief description.

In addition to very large, it is also very wide (340 miles or 550 km) and covers an area larger than the entire chain of Hawaiian islands. Olympus Mons is a mountain rather flat, only 2-5 degree slopes. There is a shield volcano built of lava, outbreak. "
