Is it the Northern or Southern Hemisphere?

The Northern Hemisphere is, of course, north of the equator. The two hemispheres neatly divide the globe in half.

The Northern Hemisphere contains 90% of Earth's land. It's where the vast majority of humans make their home.

Do you love peering into the countless stars that make up the Milky Way? Head to the Southern Hemisphere -- there, you'll have the best possible view of this dazzling night sky display.

Madagascar is a lively little country on an island located near East Africa. It is located in the Southern Hemisphere.

If you're reading this, you most likely live in the Northern Hemisphere, so you already know -- winter starts on December 21 and lasts until March. But if you live northern Minnesota, you know that the winter weather doesn't always follow a strict calendar.

The Northern Hemisphere has most of Earth's land -- the Southern Hemisphere, on the other hand, has much much more water surface area. It is essentially one vast ocean.

The Southern Cross is Crux, a constellation found in the Southern Hemisphere's night sky. It's one of the most memorable features of the entire starry sky.

Antarctica is the frozen land of the South Pole. It is entirely located in the Southern Hemisphere.

The Tropic of Cancer is just above the equator in the Northern Hemisphere. It's the most northerly location where the sun is sometimes directly overhead.

Europe is one of several continents that is totally contained within the Northern Hemispheres. Some continents try to play both sides by stretching across the equator.

The Arctic Circle is the famed frigid area that rings the top of the globe. That means it is solidly within the Northern Hemisphere.

Humans aren't yet born with gills, so we're still stuck on terra firma. And because the Northern Hemisphere features 90% of Earth's land, that's where most people live, too.

All of the United States are located in the Northern Hemisphere. However, there are some American territories located south of the equator.

South America, as the name implies, is south of the equator. Only the very northern tip of South America reaches into the Northern Hemisphere.

The Falkland Islands (or just "Falklands") are found near the east coast of South America. These little islands are in the Southern Hemisphere.

The Caribbean region is located in the Northern Hemisphere. It's the series of islands, coasts and bodies of water near the southern United States.

Africa is a huge continent that spans the equator. But about two-thirds of the continent is tucked into the Southern Hemisphere.

Argentina is a country in South America -- and it is on the southern half of the continent, meaning it is in the Southern Hemisphere.

Australia is one of the few continents located completely within the Southern Hemisphere. It's why they call Australia, "Down Under."

Because of the tilt of the Earth, the shadow on a sundial works differently depending which hemisphere you're in. In the Northern Hemisphere, the shadow moves clockwise, and in the Southern Hemisphere, it's the reverse.

Asia is the biggest continent on Earth, so it's no surprise that it stretches into both hemispheres. But it's a far from equal distribution -- almost all of Asia is in the Northern Hemisphere.

The Tropic of Capricorn is the southern counterpart to the Tropic of Cancer. It's a thin sliver of latitude around the Earth where the sun is sometimes directly overhead.

The Southern Hemisphere features a dazzling night display. It's so bright, though, that many astronomers prefer to do their work in the darker realms of the Northern Hemisphere. Otherwise, they're blinded by the South's light.

Like the Arctic Circle, the Arctic Ocean is a part of the blustery northern regions of the planet. Unlike most oceans, which span both hemispheres, the Arctic is found only in the Northern Hemisphere.

American Samoa is one of the few territories of the United States that's found in the Southern Hemisphere. Fewer than 60,000 people live on these islands in the South Pacific Ocean.

You Southerners have everything backward -- winter begins in December and summer starts in June. But no, in the Southern Hemisphere, everything is the other way around.

The "central" in Central America might make you think that this area straddles the equator ... but it doesn't. Central America is all in the Northern Hemisphere.

The auroras are an atmospheric light display found near both poles. The auroras seen in the Northern Hemisphere are the aurora borealis; those in the Southern Hemisphere are the aurora australis.

In the Northern Hemisphere, air and water tend to flow in a clockwise direction; the direction is reversed in the Southern Hemisphere, and it's due to the Coriolis force, a type of inertial witchcraft that we can't explain in just one sentence.

Only around 800 million people live south of the equator, representing just a small portion of Earth's more than 7 billion citizens. Portuguese is the most common language in the Southern Hemisphere.
