The Earth is 24,901 miles around, or 40,075km.
Denali was known for a while as Mount McKinley, but returned to its old Native American name. It is the tallest mountain on the North American continent.
World population is now 7.6 billion but growth rates are flattening as education has led women to have more opportunities and thus more chance to decide how many children they have. The result has been smaller families. If current trends continue, the world population is likely to flatten out around 11 billion.
The highest carbon footprint comes from China since it a massive population whose wealth is growing rapidly, and also because many western nations have effectively outsourced their carbon footprints by sending manufacturing there. This has resulted in horrific pollution issues, like soot particulate in the air, which kill millions of people across Asia every year as well as putting off investment in the economy. China has canceled all plans for new coal plants and just invested the better part of half a trillion dollars to go renewable, and leads the way in solar. It is also banning all cars with internal combustion engines in favor of carbon-neutral electric cars.
There are 195 countries in the world, 193 which are members of the United Nations.
Global warming has already added about 1.1C of warming. The level at which island nations will go under the seas, freshwater sources will be destroyed, and serious irreversible damage will occur is generally held to be about 2C, with anything over 6C meaning runaway warming beyond even that point, up to 300 feet of sea level rise, and mass extinction, possibly of humans. Fortunately, technology is changing very fast and current "business as usual" scenarios point to about 3.5C of rise. This is great news unless you live in an island nation. Scenarios for maintaining the threshold at 2C remain plausible but depend on human behavior over the next 50 years.
There are an estimated 500 trillion (!) ants in the world, meaning they outweigh our 7 billion humans.
The world is currently 71 percent water. This number may go up if sea levels rise, or go down if some sort of incident like an asteroid strike causes a lot of water to evaporate or temperatures to drop and lead to a very substantial freezing.
As well as being wider than the Nile, It's been proven that the Amazon is longer too, at 6992km.
Lake Baikal is 5,387 feet deep and is a UNESCO protected site.
This bridge is in the South of France and spans the Tarn River Valley. It's over 1,100 feet tall and sometimes has so much mist under it that you cannot see the ground.
At 1,114 people per square mile, Bangladesh is the most densely populated country with a big population. It is followed by South Korea, Netherlands, and Rwanda.
South Sudan became a separate country at the end of a very bloody and long civil war. It remains a very poor country and certainly has a ways to go, but it's here, and as of 2011, it's independent!
While all the nations suggested as answers here have an extremely legitimate claim, Britain's democracy is the oldest one around that currently resembles representative republican democracy as we know it and hasn't been interrupted by a period of junta rule or other tyranny.
Bhutan is the highest country in the world, though it does not contain the highest peak. It is on the Tibetan Plateau and has an average altitude of 10,761 feet.
There are 15 countries of which 12 are independent states and three are dependent territories.
The AU and the UN both agree there are 54 countries in Africa. This number does change from time to time, most recently with South Sudan becoming independent in 2011.
China's population of 1.379 billion is the largest in the world. India is second, and the USA is a distant third.
Despite abundant solar energy and new solar farms that make the cheapest electricity in the history of the world, most of the really bad offenders in this area are Middle Eastern petrostates, with Qatar leading the way as the worst per-person offender. This makes sense since these are places where you can get oil by sticking a straw in the ground. However, some forward-looking leaders in the area are starting to diversify their economies beyond oil.
Some say there are six continents, but that's if you count Europe and Asia together since they are one landmass. Generally, most scientists say there are seven continents.
The Mariana Trench is 35,462 feet deep, which means you could fit Mount Everest in it with several thousand feet to spare!
The Dead Sea is the saltiest sea and also the lowest. Due to topography that means it's surrounded by miles and miles of mountains and high ground, it is very low without filling up with water.
This point in the Gurbantünggüt Desert is 1,600 miles from the ocean, the furthest inland it is possible to go.
Technically, seven nations own Antarctica and have overlapping claims on it, meaning no one nation really owns it. However, since you can't really build there and it's dark half the year, no one has ever had a war about it.
While territorial waters do extend a couple miles off a country's coastline (assuming there isn't another country within that distance), technically no one owns the ocean. This is a source of much contention since it means that people treat it like a garbage pit, no one looks after the fish, coral, and other habitats in parts of it, and whoever had the best navy generally dominated it. New treaties and policies are set to protect the oceans better in the future, modeled after successful anti-pirate treaties.
The Silk Road was a trade route of the Middle Ages that connected East and West. Parts of it are now World Heritage Sites.
Since Croatia joined in 2013, the number has been 28. Britain is going to leave in 2019 unless there is another referendum.
Hong Kong was on a 99-year lease and returned to China in 1997, a peaceful transfer of power. It remains the world financial center it became under the British.
At its height, the Empire covered 24 percent of the planet and was so vast that the sun never set on it.
These five territories are permanently inhabited. Some are interested in statehood, which would mean getting representation in Congress.
Climate change hasn't changed the answer to this yet, but it looks like it will soon, with Kuwait and parts of Iran looking set to take the crown.
This temperature was set in June 2017. While hotter temperatures are claimed, this one is the most reliable ever recorded.
The Earth moves at 67,000 mph, but thanks to its spin and gravity, you don't feel it at all!
Air pressure declines dramatically as you go up from the surface, and the vast majority of air is under 10 miles away from the surface of the planet. However, you're not technically in space until you are 300 miles up.
Yes, that's right. If we continue burning fossil fuels and emission levels continue to go up, we could cause a fatal collapse in the West Antarctican ice sheet that would mean a 12-foot rise in sea levels within the lifetime of children already born. Fortunately, this is very unlikely even if we did burn all that oil, gas, and coal. However, we have probably locked in a 1- 3-foot rise from current emissions, so it's good news that emissions levels are already stalling and look set to be in decline by 2025 as carbon neutral energy achieves market incumbency.
