Explanations: answer key for all 10 questions

Q1: Which mountain is the tallest on Earth when measured from its base on the ocean floor?
Answer: Mauna Kea
Mauna Kea in Hawaii rises about 10,200 meters from its base, though only around 4,200 meters are above sea level. Everest is highest above sea level.
Q2: The deepest known point in the ocean, Challenger Deep, lies in which trench?
Answer: The Mariana Trench
Challenger Deep is nearly 11,000 meters deep, in the western Pacific. Only a handful of people have visited the bottom.
Q3: The shores of which body of water are the lowest land point on Earth?
Answer: The Dead Sea
The Dead Sea shore lies more than 430 meters below sea level, and the level keeps dropping each year.
Q4: Angel Falls, the world's highest uninterrupted waterfall, is in which country?
Answer: Venezuela
Angel Falls drops 979 meters from a tabletop mountain called Auyán-tepui. Its local name is Kerepakupai Merú.
Q5: What is the largest island in the world that is not a continent?
Answer: Greenland
Greenland covers more than 2 million square kilometers, and about 80 percent of it is covered by an ice sheet.
Q6: What is the largest desert on Earth, counting cold deserts?
Answer: Antarctica
A desert is defined by low precipitation, not heat. The Sahara is the largest hot desert.
Q7: Which body of water is the largest lake in the world by surface area?
Answer: The Caspian Sea
Despite its name, the Caspian Sea is a lake. It is bordered by five countries, including Russia, Kazakhstan and Iran.
Q8: The highest air temperature ever officially recorded, 56.7°C, was measured in 1913 at which place?
Answer: Death Valley
The reading was taken at Furnace Creek in California's Death Valley. Satellites have recorded even hotter ground temperatures in Iran's Lut Desert.
Q9: Mawsynram, often called one of the wettest places on Earth, is in which country?
Answer: India
Mawsynram, in the state of Meghalaya, receives over 11 meters of rain a year on average, mostly during the monsoon.
Q10: The coldest air temperature ever recorded on Earth, about −89°C, was measured at which station?
Answer: Vostok Station
The record was set at Russia's Vostok Station in Antarctica in July 1983. Oymyakon in Siberia is the coldest permanently inhabited village.

Geography Quiz – Earth's Most Extreme Places

Our planet is full of extremes. Mountains rise kilometers into the sky, ocean trenches plunge even deeper, and some places are scorching hot, freezing cold or soaked with rain for months at a time. Learning about these record-breaking places is one of the most exciting ways to understand how Earth's land, water and climate work.

Mount Everest, on the border of Nepal and China, is the highest point above sea level at 8,849 meters. But measured from its base on the sea floor, Hawaii's Mauna Kea is taller. At the other extreme, Challenger Deep in the Mariana Trench is the deepest known point in the ocean, while the shores of the Dead Sea are the lowest dry land on Earth.

Water creates its own records. Angel Falls in Venezuela is the highest uninterrupted waterfall, the Caspian Sea is the largest lake by area, and Greenland is the largest island that is not a continent. Deserts are defined by how little precipitation they receive, which is why icy Antarctica counts as the largest desert, ahead of the Sahara.

Climate extremes are just as striking. Death Valley in California holds the record for the highest air temperature, while Vostok Station in Antarctica recorded the coldest. Mawsynram in India is one of the wettest inhabited places on Earth. Scientists track these records carefully, and new satellite measurements continue to reveal surprising details about our planet.

This quiz covers the highest, lowest, hottest, coldest and wettest places on Earth.
