Why is the ocean blue?
•It is commonly believed that the ocean is blue because of the sky reflecting off of it. But the ocean is blue because of the way it absorbs sunlight. It strongly absorbs colors at the red end of the wavelength spectrum, as well as the violet end, so what remains is mostly blue.

A. Human Activity
"According to the National Climate Assessment, human influences are the number one cause of global warming, especially the carbon pollution we cause by burning fossil fuels and the pollution-capturing we prevent by destroying forests. The carbon dioxide, methane, soot, and other pollutants we release into the atmosphere act like a blanket, trapping the sun's heat and causing the planet to warm. Evidence shows that 2000 to 2009 was hotter than any other decade in at least the past 1,300 years<span>. This warming is altering the earth's climate system, including its land, atmosphere, oceans, and ice, in far-reaching ways."

Answer: 360°
Explanation;
Lines of longitude are imaginary lines that used along with latitudes allow us to be able to locate points on Earth. Longitudes are drawn vertically on maps with the most popular one being the Prime( Greenwich) meridian.
As the Earth is spherical, the lines of longitude encircle the Earth which means that an entire longitudinal line will be 360°. As maps are flattened out, the longitudinal line is divided into 2 such that the longitudinal lines seen on a map are 180° each. When a line of longitude is added to its opposite, they will reform the original line that runs around the earth thereby making 360°.
Answer:
A nation-state is a state where the vast majority of the population is comprised of a single ethnic group which also serves as a motivation and reason for the formation of the state.
Explanation:
A nation-state is a term used for the nations where the vast majority of the population is comprised of a single ethnic group, usually over 90%. There are multiple examples of such states around the world, some of which are fully recognized, while some function in practice as such but are not officially recognized by the United Nations. In the first category, we have the likes of Mongolia, Iceland, and numerous island nations in the Pacific, while in the second one we have the likes of Kosovo and South Ossetia.
These nations are often formed on the basis of the distribution of an ethnic group, thus determining the boundary in accordance with where the particular ethnic group is found without interruptions. An interesting case was the recent referendum for independence in Scotland as if it was successful it would have meant the creation of another nation-state. This was carefully monitored by many ethnic groups in the world because they saw it as an opportunity to create their own nation-states.
