1. Dead Sea coastline
   Mariana Trench
2. Lake Baikal coastline
   Bentley Subglacial Trench

The Bentley Subglacial Trench is in Antarctica and very far inland. It is over 7000 feet below sea level, making it by far the lowest non-watery place on the planet.

1. Sahara Desert
   Antarctica
2. Atacama Desert
   Gobi Desert

The Atacama is the driest. Antarctica is technically also a desert too!

1. Honey fungus
   Blue whale
2. Sequoia
   African bush elephant

The honey fungus is not an animal or a vegetable, but that guy is huge. It's the biggest living thing on the planet, clocking in at 2,200 acres.

1. Golden eagle
   Peregrine falcon
2. Kestrel
   Arctic tern

The peregrine falcon is one heck of a badass. It goes horizontal at a paltry 50mph but it can dive up to 200mph.

1. Monaco
   San Marino
2. Vatican City
   Liechtenstein

Monaco is only a few square blocks but there are a lot of people in them!

1. Japan
   Sao Tome
2. Colombia
   Maldives

As a densely jungle-covered nation, Colombia enjoys many feet of rainfall per year.

1. It's the deepest lake in the Southern hemisphere.
   It's the biggest freshwater supply in Australia.
2. It's the most densely populated lake in the world by number of fish.
   It's pink! Pink, I say!

Lake Hillier is pink. Really pink. Bottle the water and it's still pink. It's not just half-assed pink, either - it's bubblegum pink. It might be because of special salt, it might be bacteria, but either way, that is one pink lake.

1. An inch per year
   A foot per year
2. A yard per year
   They are no longer moving.

The continents move an inch per year. If they were going much faster, it would get very complicated to build anything!

1. Niagara Falls, Canada
   Baffin Island, Canada
2. Kalaupapa Cliffs, Hawaii
   Cliffs of Moher, Island

Mt. Thor on Baffin Island has the highest single drop. There are higher cliffs with breaks in them, but this one is 4000 feet straight down, with a total drop of over 5500 feet.

1. A lake
   The sea
2. A lake in another lake
   A river

It's actually an island in a lake, in an island, in a lake! Picture a donut with another donut inside it.

1. Lake Baikal
   Lake Tanganyika
2. Lake Malawi
   Loch Ness

At over 5300 feet deep, Lake Baikal in Russia is the big daddy of all lakes. It's more than a mile deep!

Yep, Russia literally goes almost halfway around the world. It's that big.

1. San Marino
   Luxembourg
2. Vatican City
   Monaco

Vatican City is just a few blocks. It's teeny tiny!

1. Los Angeles
   Reno
2. They are at exactly the same longitude.
   It depends where you measure from as they are both big.

It's hard to imagine but yes, Reno is actually entirely west of LA. Seriously, look at a map.

1. Somalia
   Ghana
2. Cape Verde
   Morocco

This will blow your mind: the state that is the shortest distance to Africa is Maine.

1. Kazakhstan
   Congo
2. Uzbekistan
   Azerbaijan

Uzbekistan is in Central Asia - that is, central Central Asia.

1. The Giant Fart
   The Gate to Hell
2. The Great Burp
   The Eye of Sauron

It's a collapsed natural gas mine in Derweze, Turkmenistan that truly does look like Hell is underneath it and trying to get out.

1. Hawaii
   Alaska
2. Florida
   Trick question: none does.

Longitude lines converge at the top of the planet so Alaska's very northerly position mean it actually reaches into the eastern hemisphere.

1. Grand Canal, Venice
   Eerie Canal, Canada
2. Panama Canal, Panama
   Grand Canal, China

The Beijing-Hangzhou Canal is 1104 miles long! It's also really old in places, dating back to the 5th century. It is a tourist attraction as it is very beautiful.

1. London, UK
   Hulunbuir, Mongolia
2. New York, USA
   Shanghai, China

Hulunbuir doesn't have the most people, by any stretch, but it's really spread out.

1. 50%
   90%
2. 30%
   75%

It contains most of the land, but even more importantly, it contains the vast majority of the fertile land. Hence, most of the people live there!

They are: China, the USA, India, and Indonesia. The next biggest is Brazil, around 200m.

There's Guinea, Equatorial Guinea, Guinea-Bissau and Papua New Guinea. That's a lot of guineas!

1. Sedimentary
   Alloy
2. Igneous
   Metamorphic

Rocks are either sedimentary, metamorphic or igneous, but they do not include alloys - those are mixes of metals.

1. China
   Philippines
2. Mongolia
   Mexico

The cave was flooded once but due to pumping in the Naica Mine, now it can be visited, though it's nearly maximum humidity and over 90F, so it's not very nice in there and you can only spend short periods inside without protective gear. It's in Naica, Chihuahua, Mexico and is full of selenite crystals so vast that a human is dwarfed by them.

1. Coast redwood
   Giant sequoia
2. Kauri
   Eucalyptus regnans

The biggest tree is General Sherman, a very mighty giant sequoia. By volume, it is about 50% bigger than the nearest competition.

1. Golden Gate Bridge, America
   Duge Bridge, China
2. Sidu River Bridge, China
   Baluarte Bridge, Mexico

Bridge height is measured from deck to ground below, not structure height. At 1854 feet from the deck to the ground, the Duge Bridge in China is the highest. Eight of the world's highest bridges are in China.

1. 10 miles
   35 miles
2. 7 miles
   22 miles

The Channel is 22 miles wide from Dover to Calais. It is a famously tough swim as the current is very strong because of the narrowing, and the cold water from the North Sea is very harrowing on the body. Some people have swum it many times, though!

1. Yes, of course.
   No, it is flat.
2. No, it is slightly squashed.
   No, it is a buckyball.

The world is not a perfect sphere. It is slightly squashed. That means you are further from the core when you are on the equator than at the North Pole, even if you are at sea level.

China is very big, and has many neighbors: 14, to be precise.

1. Asia
   Africa
2. Antarctica
   South America

90% of the fresh water on the planet is in Antarctica.

1. Australia
   Canada
2. They are the same length.
   Nobody knows because Canada's icy coastline cannot be measured.

It's Canada! Australia is bigger, but it has a less "wiggly" shape so the coast is shorter.

1. Three quarters
   One third
2. Half
   90%

Yes, Canada is big, and yes, it has a LOT of lakes. More than half of them, to be precise.

1. Mount Everest
   Mount Chimborazo
2. Denali
   Mount Kilimanjaro

Since the planet is not actually round, Everest isn't the highest point. Mount Chimborazo in Ecuador is higher.

1. Maine, of course!
   London, of course!
2. They are the same latitude.
   It's impossible to say because of the way the planet is shaped.

People think of Maine as very far north, but it isn't. London's mild climate - its winters never see snow that is typical to Maine annually - is thanks to oceanic currents.
