The exosphere is really high up and you can't breathe there. You find a bit of hydrogen and other very light gases up there, but it's mostly just a super-thin atmosphere-like area.

What is the concentration of carbon dioxide in the atmosphere in parts per million (ppm)?

Carbon dioxide used to be 280ppm. It's now at 410ppm, rising about 2-3ppm a year. At 450ppm, irreversible runaway climate change starts to become quite possible.

Population growth is slowing. When do recent studies show that the population will level off?

What is the difference between soil and dirt?

Soil has bacteria and all kinds of life in it. Dirt is just crushed-up stuff.

What is carbon sequestration?

Carbon sequestration is a necessary part of combating climate change. Farming practices, direct air capture, closed loop burning of plants and other options are all part of the nascent technologies that will keep carbon levels to amounts that civilization can live with.

What is a floodplain?

Floodplains are around rivers. Thanks to sediment and nutrients from the river, they are usually very fertile and lovely places to live. They just flood a lot, that's all.

You've definitely seen one. But: What is a river?

Jericho has been inhabited for 11,000 years, putting a close second to Damascus.

Null Island is at zero latitude, zero longitude. What body of water is it in?

Null Island is where photos are geotagged if they have no tag. That means that technically, more photos are taken of Null Island than anyplace on Earth - except that it is just a spot in the South Atlantic.

What caused the Tunguska Event?

The Tunguska blast was when a meteor hit northern Russian some 100 years ago. It made a fireball 300 feet wide and flattened 80 million trees!

You can visit them but due to 100% humidity and 90F temperatures, you must wear a special suit.

About This Quiz

Let's be honest: geography is usually taught really badly in schools. We're fed it as if the story of our world is just a random grab-bag of facts, mostly unrelated to each other. There are all sorts of types of clouds and mountains and facts about volcanoes, and then there's something called demographics which is about people and ages and family types, meaning it's annoyingly tied up with history, the other horribly-taught member of the humanities. It's all terribly confusing and not very interesting.

Fortunately, geography is actually extremely interesting - it's just that most of us don't figure this out until after we get out of our formal educations. Geography is about how all the physical factors of the world shape the way that people are able to live in it. The history of how we are able to live in the world is one great big story with all sorts of fascinating elements that inform and shape one another, and that are inextricably linked. It's a story of how oceans prevented wars, changing climates brought down great civilizations, landscapes empowered prosperity, fueled invention, and enabled billions of people to be raised from poverty. How much do you know about this magical world of ours? Let's find out!
