Why Sky is Blue?
Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

What makes a red sunset?
As the sun gets lower in the sky, its light is passing through more of the atmosphere to reach you. Even more of the blue light is scattered, allowing the reds and yellows to pass straight through to your eyes.
Sometimes the whole western sky seems to glow. The sky appears red because small particles of dust, pollution, or other aerosols also scatter blue light, leaving more purely red and yellow light to go through the atmosphere.

What is the 11 year solar cycle?
The solar cycle or solar magnetic activity cycle is the nearly periodic 11-year change in the Sun's activity (including changes in the levels of solar radiation and ejection of solar material) and appearance (changes in the number and size of sunspots, flares, and other manifestations).

What is an Ice Age?
An ice age is a long period of reduction in the temperature of the Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation, known in popular terminology as the Ice Age.

Which is the longest river in the world?
The Nile is credited as the longest river in the world. Its main source is Lake Victoria in east central Africa. From its farthest stream in Burundi, it extends 6,695 km (4,160 miles) in length.
The two longest rivers in the world are the Nile, flowing into the Mediterranean, and the Amazon, flowing into the South Atlantic. Which is the longer is more a matter of definition than simple measurement.

What is considered to be a Dwarf Planet?
According to the definition adopted by the IAU in 2006, a dwarf planet is, “a celestial body orbiting a star that is massive enough to be rounded by its own gravity but has not cleared its neighboring region of planetesimals( a minute planet) and is not a satellite. More explicitly, it has to have sufficient mass to overcome its compressive strength and achieve hydrostatic equilibrium.”

What is the largest Organ of Human body?
We have been told, since time immemorial, that the liver was the biggest internal organ in the human body, making the skin the largest external one. Weighing about 8 pounds (3.6 kilograms) and covering 22 square feet (2 square meters) in some cases, the versatile skin has been considered the largest human organ.

Which Country Has the Most Islands?
Estimates show that approximately 700 million people on earth live on islands. Due to their isolation, islands usually offer a unique environment as they tend to be hotbeds of biodiversity with rare flora and species. It is estimated that Sweden has more islands than any other country in the world. Sweden has an estimated total of 221,800 islands, the majority of which are not inhabited.

What is Crust of Earth?
In geology, a crust is the outermost layer of a planet.
The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks.
The crust is underlain by the mantle. The upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust.
The boundary between the crust and mantle is conventionally placed at the Mohorovicic discontinuity, a boundary defined by a contrast in seismic velocity.
Earth's crust occupies less than 1% of Earth's volume. The oceanic crust of the Earth is different from its continental crust.

What does the Big 4 mean?
Big 4 usually refers to the four largest accounting and auditing firms: PricewaterhouseCoopers, Deloitte Touche Tohmatsu, Ernst & Young, and KPMG. These certified public accounting (CPA) firms perform most of the audits which are required of U.S. corporations having stock that is publicly traded.

What Is the Consumer Price Index – CPI?
The Consumer Price Index (CPI) is a measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food, and medical care. It is calculated by taking price changes for each item in the predetermined basket of goods and averaging them. Changes in the CPI are used to assess price changes associated with the cost of living; the CPI is one of the most frequently used statistics for identifying periods of inflation or deflation.

What is the main component of greenhouse gases?
Greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. The major greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds); carbon dioxide, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%.

Amazing Facts About the Snake
1.There are over 3000 kinds of snakes in the world. They are present in every continent except Antarctica
2. Snakes cannot bite their food so in order to eat large prey, they will unhinge their jaw to swallow the food whole
3.Snakes such as boas and anacondas suffocate their prey by squeezing it to death
4. Snakes use their tongue to smell
5. 70% of snake species lay eggs while the other 30% give birth to live young

What is Chimera?
A chimera is essentially a single organism that's made up of cells from two or more "individuals"—that is, it contains two sets of DNA, with the code to make two separate organisms. One way that chimeras can happen naturally in humans is that a fetus can absorb its twin.

What is a period and why do we have them?
A period is when a woman’s body releases tissue it no longer needs. This tissue comes from the uterus, which is where a baby (fetus) can develop in the female body. Every month or so, the uterus lining gets thicker to prepare for a fertilized egg if the woman becomes pregnant. If the egg doesn’t get fertilized, that lining is released from the body as blood through the vagina. This monthly process is called menstruation or a period.So when a girl has her period, her body is just getting rid of a small amount of blood and some unneeded tissue. It is a natural, normal body process for all females as they become women and mature physically.

What is “CRISPR”?
“CRISPR” (pronounced “crisper”) stands for Clustered Regularly Interspaced Short Palindromic Repeats, which are the hallmark of a bacterial defense system that forms the basis for CRISPR-Cas9 genome editing technology. In the field of genome engineering, the term “CRISPR” or “CRISPR-Cas9” is often used loosely to refer to the various CRISPR-Cas9 and -CPF1, (and other) systems that can be programmed to target specific stretches of genetic code and to edit DNA at precise locations, as well as for other purposes, such as for new diagnostic tools.

What is the concept of Space?
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is, often conceived in three linear dimensions, although modern physicists, usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime.
The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.
