Top 10 Most Challenging Geographic Trivia Questions

So, you think you know the world map? You've played countless rounds of Globdrop, you know the capital of every European nation, and you can point out Madagascar without blinking. It’s time to put your spatial knowledge to the ultimate test.

Our brains often rely on generalizations and flawed mental maps (thanks, Mercator projection). These 10 trivia questions exploit those common geographical misconceptions. Read the questions, make your best guess, and then check the answers below.

The Questions

1. Which state in the USA is the closest to Africa?
2. If you travel directly south from Detroit, Michigan, what is the first foreign country you enter?
3. What is the only country in the world that does not have a rectangular flag?
4. Which continent covers all four hemispheres (Northern, Southern, Eastern, and Western)?
5. What is the largest desert in the world? (Hint: It’s not the Sahara).
6. Which two countries share the longest international border in the world?
7. Mount Everest is the highest mountain above sea level, but what is the tallest mountain from base to peak?
8. Which country has the most islands within its borders?
9. Reno, Nevada, is further west than Los Angeles, California. True or False?
10. Which city is located across two different continents?

The Answers

1. Maine

Most people guess Florida because it’s the southernmost state on the East Coast. However, because of the curvature of the Earth and the eastward bulge of the North American continent, a small peninsula in Maine (Quoddy Head) is actually just 3,154 miles away from El Jadida, Morocco, making it the closest US state to the African continent.

2. Canada

Look closely at a map of the Great Lakes. The city of Windsor, Ontario (Canada), sits directly south of the Detroit River. So, if you go due south from downtown Detroit, you enter Canada.

3. Nepal

The flag of Nepal consists of two stacked triangles (officially known as pennons). It is the only national flag in the world that is not a rectangle or a square.

4. Africa

Africa is the only continent that is crossed by both the Equator (dividing North and South) and the Prime Meridian (dividing East and West), placing parts of its landmass in all four hemispheres.

5. The Antarctic Desert

A desert is not defined by heat or sand; it is defined by precipitation (specifically, receiving less than 10 inches of rain or snow per year). The Antarctic Desert covers the entire continent of Antarctica (5.5 million square miles) and is the driest and largest desert on Earth.

6. Canada and the United States

The US-Canada border stretches for 5,525 miles (8,891 km), making it the longest international border in the world. It includes the border shared with the contiguous US as well as the border with Alaska.

7. Mauna Kea (Hawaii)

While Mount Everest is the highest altitude above sea level, Mauna Kea is technically taller. Its base sits deep on the Pacific Ocean floor. From base to peak, Mauna Kea measures over 33,500 feet (10,210 meters), beating Everest by over 4,000 feet.

8. Sweden

While Indonesia and the Philippines are famous archipelago nations, Sweden actually holds the record. It has over 267,000 islands, though less than 1,000 of them are inhabited.

9. True

Look at the map. The coast of California curves heavily eastward as it goes south. Reno, Nevada, sits at 119.8° W longitude, while Los Angeles sits at 118.2° W longitude. Reno is indeed further west than LA.

10. Istanbul, Turkey

Istanbul is famously situated on the Bosphorus Strait. The western half of the city lies in Europe (Thrace), while the eastern half lies in Asia (Anatolia), making it a truly transcontinental metropolis.

How many did you get right? If you struggled, it might be time to fire up a game of Globdrop and give your internal map a much-needed recalibration.
