The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometers (1,400 mi) over an area of approximately 344,400 square kilometers (133,000 sq mi).
<h3>
What are coral reefs?</h3>
Coral reefs are underwater structures made from calcium carbonate secreted by corals. Coral reefs are colonies of tiny living animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups.

Answer:
Interestingly, many French maps showed zero degrees in Paris for many years despite the International Meridian Conference’s outcomes in 1884. GMT was the universal reference standard – all other times being stated as so many hours ahead or behind it – but the French continued to treat Paris as the prime meridian until 1911. Even so, the French defined their civil time as Paris Mean Time minus 9 minutes and 21 seconds. In other words, this was the same time as GMT.
In 1972, Coordinated Universal Time (UTC) replaced GMT as the world's time standard. France did not formally use UTC as a reference to its standard time zone (UTC+1) until August in 1978.
Standard time, in terms of time zones, was not established in United States law until the Act of March 19, 1918. The act also established daylight saving time in the nation. Daylight saving time was repealed in 1919, but standard time in time zones remained in law, with the Interstate Commerce Commission (ICC) having the authority over time zone boundaries.
Many countries started using hourly time zones by the late 1920s. Many nations today use standard time zones, but some places use 30 or 45 minute deviations from standard time. Some countries such as China use a single time zone even though their territory extends beyond the 15 degrees of longitude.
The Volga is the longest river in Europe. It is also Europe's largest river in terms of discharge and drainage basin. The river flows through central Russia and into the Caspian Sea, and is widely regarded as the national river of Russia.
Answer:A heavy layer of smog hangs over the city. We can see it as we rise into the sky. We fly away from Faridabad, the second most polluted city in the world, and into the pristine mountains of Leh.
I stayed up until 2 am last night, researching what happens to a body when it flies into a high-altitude city. I ended up taking a Diamox tablet just to help with the nerves. The hour long flight is filled with sweaty palms as I wonder what’s going to happen when they depressurise the cabin. The internet told tales of people vomiting in the airport, the altitude got to them so quickly. Hospitalisation and oxygen tanks. People rushing in taxis to a lower town. Having hiked to 5600m, last time I was in the Himalayas, I know what it feels like to not have enough oxygen. Sleepless nights, exhaustion, headaches.
The plane shakes as it lands and I grip the arm of my seat. I never used to be scared of flying, but lately, I’m intensely aware of all the possible ways this life may end too soon. I’ve been taking fewer risks lately. I wonder if it’s just a natural part of getting older. I’m turning 28 next month. Or if there’s been a shift in the natural order of things. If the book I’m reading, Salman Rushdie’s The Ground Beneath her Feet, is telling some sort of truth about parallel universes getting too close, and about rifts forming and threatening an end to things. It would explain why the world seems so on edge lately.
