WORLD COUNTRIES-CAPITALS AND FLAGS
DO YOU KNOW HOW MANY COUNTRIES ARE THERE IN WORLD?
When one asks this question different number of answers pop up.Different sources provide different numbers.
The best possible answer is that there are 195 countries in the World.There are 192 members of the United Nations. Unfortunately, the number 192 is too often used to represent the number of countries in the world. Although this number represents almost all of the countries in the world, there are still two recognized independent countries, the Vatican City and Kosovo, that are independent and are not members of the U.N. so 192 is not the number of countries in the world.
The United States' State Department recognizes 194 independent countries around the world. Their list of 194 countries reflects the political agenda of the United States of America and its allies. Missing from the State Department's list is one entity that may or may not be considered a country, depending on who you talk to.
Taiwan meets the requirements of independent country or state status. However, due to political reasons, it fails to be recognized by the international community as independent. Nonetheless, it should be considered as independent.
Taiwan was actually a member of the United Nations (and even the Security Council) until 1971, when mainland China replaced Taiwan in the organization. Taiwan continues to press for full recognition by other countries, to become "part of the club" and fully recognized worldwide but China claims that Taiwan is simply a province of China.
Thus the best possible answer would be 195 countries.However recognize that there are dozens of territories and colonies that are sometimes erroneously called "countries" but don't count at all - they're governed by other countries. Places commonly confused as being countries include Puerto Rico, Bermuda, Greenland, Palestine, Western Sahara, and even the components of the United Kingdom (such as Northern Ireland, Scotland, Wales, and England - they're not fully independent countries, states, or nation-states).
Here is the list of all 195 countries with their capitals and flags.

Afghanistan - Kabul
Albania - Tirane
Algeria - Algiers
Andorra - Andorra la Vella
Angola - Luanda
Antigua and Barbuda - Saint John's
Argentina - Buenos Aires

What gives Sunrise and Sunset an orange glow?
Do you know why there is an orange glow around the Sun at the time of Sunrise and Sunset?Here is the answer........
At the Sunrise and Sunset,we see the Sun through a greater thickness of air because it is low in the sky.Therefore,we are looking at it across the Earth's surface rather than directly up into the sky.
At these times,the sky often turns orange-red because the "photons" of red and orange light are scattered through the atmosphere around us.
As the Sun sets or rises,its light travels to us across the Earth's surface.The colours of the spectrum are gradually scattered.Red and Orange are the last to be scattered before the Sun finally sets or rises.
