  • Okay.

  • Is this statement correct or bogus: If someone asked you to show where North is on a map,

  • you'd instinctively point up, right?

  • But would you believe it wasn’t always that way?

  • And are the continents really moving because I don’t feel any shifting under my feet!

  • Let’s play a little game oftrue or false”!

  • (I’ve got a sweet bonus for ya at the end too!)

  • 1) Mount Everest is the highest summit on the planet.

  • False: Everest stands a proud and impressive champion

  • at just over 29,000 ft above sea level.

  • But it's not the closest point to space!

  • Because our planet isn't perfectly round but more of a squashed sphere, mountains closer

  • to the equator get some extra elevation.

  • This is how Chimborazo in Ecuador is the closest you can get to the Sun and stars.

  • And if you dive into the Pacific, you'd find a giant that's 3,000 feet taller than Everest.

  • Above sea level, though, Mauna Kea is just 13,800 ft tall.

  • The rest is hidden underwater.

  • Speaking of things hiding in the ocean

  • 2) The Mariana Trench could fit Everest in it completely.

  • True: The deepest place on this planet could easily

  • host Everest and still have room for another decently sized 7,000-ft-tall mountain!

  • 3) A sea must have a coast.

  • False: The Sargasso Sea is nothing like your regular

  • vacation destination.

  • It has no coasts whatsoever.

  • It’s surrounded by 4 ocean currentsthe Gulf Stream in the West, the North Atlantic

  • Current in the North, the Canary Current in the East, and the North Atlantic Equatorial

  • Current in the South.

  • That means its borders are always shifting.

  • 4) The continents are constantly moving.

  • True: And theyre doing it at the same speed your

  • fingernails are growing!

  • As a result, the Pacific Ocean is shrinking by about an inch a year.

  • So, Asia and North America are getting closer every year (yay shorter flights!), but Europe

  • is drifting away as the Atlantic widens (aw, longer trips…).

  • 5) Iceland is becoming larger each year.

  • True: And it's a natural process.

  • The land of geysers is also the place where the Eurasian and North American tectonic plates

  • meet.

  • The gap between them is growing by nearly 2 inches a year.

  • 6) The African continent sits in all 4 hemispheres.

  • True: Africa is the only continent that spans over

  • the northern, southern, eastern, and western hemispheres.

  • I mean, it does cover 12 million square miles – I’d expect at least a few hemispheres

  • in there!

  • Both the Prime Meridian and the Equator cross it, and that's unique too!

  • 7) The people on Earth are evenly spread.

  • False: 90% of the entire population (that’s around

  • 7 billion out of 7.7 billion people) live in the Northern Hemisphere.

  • Before you imagine igloos, polar bears, and eternal winterthe North actually includes

  • North America, Europe, most of Africa and Asia, and even some parts of South America!

  • 8) The Earth is extremely densely populated.

  • False: If we all squeezed up like residents in any

  • major city, we’d need much less room than the entire planet Earth.

  • 250, 000 square miles would do.

  • That means we could all fit into the state of Texas, and still have some room to spare!

  • But the price of apartments in Houston and Dallas would skyrocket!

  • 9) There’s plenty of drinkable water here on the Blue Planet!

  • False: 71% of the Earth might be covered by water,

  • but it's not the kind you'd drink first thing in the morning.

  • Only 2.5% of that water is fresh, and only 1% is available to drink.

  • The rest makes up glaciers and snowfields.

  • Salty seawater has its own benefits though, and humanity is always finding innovative

  • ways to use it, from new technologies to the beauty industry.

  • 10) The Sahara Desert is always hot.

  • False: Most people think of it as the driest and

  • one of the hottest places on Earth, but it does get snow!

  • In the last 40 years, it’s happened 3 times already.

  • So it does get chilly sometimes, mostly during long winter nights.

  • Speaking of unexpected places where you can find snow

  • 11) It snows in Hawaii.

  • True: Hawaii’s volcanoes Mauna Kea (remember what

  • it’s famous for?), Mauna Loa, and Haleakala all rise above 10,000 ft.

  • This altitude is high enough to get a good amount of the white fluffy stuff during winter.

  • 12) The North Pole is the coldest place on Earth.

  • False: The South Pole is!

  • It's because the North Pole sits on floating chunks of ice.

  • That ice is thin enough to let the heat coming from the Arctic Ocean get through.

  • Antarcticahome to the South Poleis a massive continent that doesn't have such

  • a natural heater.

  • The average winter temperature there is -76°F, compared to -40°F in the North.

  • 13) The North is alwaysup.”

  • False: Old Egyptian maps had South asupbecause

  • that's where they lived.

  • In Medieval times, “Northwas actually East on many maps because that's where the

  • Sun rises.

  • People heading to the Americas held maps with West where you’d expect North to be today.

  • Ptolemy was the first to put north on top of a “globalmap, but that could be because

  • he didn’t have much information on the Southern Hemisphere.

  • Centuries later, people discovered there’s a magnetic north pole where a compass needle

  • will point straight down.

  • That's only possible at the Geographic North Pole.

  • But technically, you could mark that point anywhere on the map, not just the very top

  • especially now that the magnetic north pole is moving!

  • Who knows where the North might end up centuries from now?

  • 14) Youre walking on gold every day.

  • True: The Earth's core is home to some expensive

  • substances, including diamonds and gold!

  • If you took all the gold out and spread it on the surface, it would be enough to cover

  • the entire planet in a 2-ft-thick layer up to your knees!

  • That’s an expensive highway!

  • 15) There are no more real isolated areas on this planet.

  • False: Two words: Point Nemo.

  • Nemotranslates from Latin asno oneand it’s the perfect name for a place

  • so remote from any land – 1,000 miles in any directionthat astronauts are the

  • closest humans to it.

  • When the International Space Station is flying over Point Nemo, the crew is only 260 miles

  • away from it!

  • 16) Two people can be 43 miles yet 24 hours apart.

  • True: In 2011, Samoa just skipped December 30 and

  • became 3 hours ahead of Sydney Australia, the nearest large business center.

  • It used to be 21 hours behind it.

  • So now, Samoa and American Samoa are a mere 43 miles yet a whole 24 hours apart!

  • 17) A journey down the Mississippi River takes 90 days.

  • True: That is, if youre a droplet of water.

  • Three months is what it takes to cover the distance of almost 2,350 miles from Lake Itasca

  • in Northern Minnesota to the Gulf of Mexico.

  • Would you want to go on that journey?

  • Let me know in the comments below!

  • 18) Canada has the highest concentration of lakes.

  • True: Over half of all the natural lakes on Earth

  • are in the Great White North.

  • That’s over 30,000 of those natural pools covering 9% of the country’s territory.

  • 19) Kentucky has the longest cave in the world.

  • True: If you ever visit Mammoth Cave National Park,

  • you'll only get a sneak peek of the largest cave system on the planet.

  • 400 miles have already been officially explored, and half as much is believed to still be waiting

  • underground.

  • 20) The poles are in all time zones at the same time.

  • True: If someone asked you what time it is during

  • a trip to either the North or the South Pole, you could never give them the right answer.

  • That's because all the longitude lines that divide one time zone from another come together

  • here.

  • Technically, you could use any time, but most people stick to their country’s research

  • station's zone.

  • Bonus!

  • I enjoyed this journey around the globe with you so much, that I’d like to show you something.

  • Well need to take a quick trip down to the Great Barrier Reef.

  • Here it is – a heart-shaped reef to show how much I appreciate ya!

  • Hey, if you learned something new today, then give the video a like and share it with a

  • friend!

  • And here are some other videos I think you'll enjoy.

  • Just click to the left or right, and stay on the Bright Side of life!

Okay.
