Why, in question 10: What is the deepest lake in the world?
The answer is Baikal, in Siberia, at about 1,640 meters at its deepest point. Superior, in North America, is the largest freshwater lake by area, and Titicaca, in the Andes, is one of the highest navigable lakes in the world.
Lakes that look like seas
The largest lake in the world by area is the Caspian Sea, between Europe and Asia. Despite its name as a sea, it is landlocked and has brackish water.
Lake Victoria, in Africa, is the largest tropical lake in the world and one of the main sources of the Nile River.
Titicaca lies more than 3,800 meters above sea level, on the border between Peru and Bolivia, and has floating islands made of totora reed, built and maintained by the Uru people.
Brazil does not have large natural lakes like these, but it has huge reservoirs, and the Lagoa dos Patos, in Rio Grande do Sul, is among the largest lagoons in South America.
What this quiz covered
Questions 1, 3, 4, 5, 6 and 10 were about records: the largest ocean, the highest mountain, the largest country, the largest hot desert, the river with the most water and the deepest lake. In many of them, the criterion changes the answer, such as above sea level or from base to top, by area or by volume.
Questions 2, 7 and 8 dealt with climate, water and air: the coldest continent, how much of the planet is water and what air is made of.
Question 9 was about Brazil and its six biomes. Anyone who wants to go further will find more facts like these in the list of curiosities about planet Earth.
Where this information comes from: IBGE (Brazil's biomes and area); NASA and NOAA (oceans, water and atmosphere); official measurement by China and Nepal, 2020 (Everest); UNESCO (Baikal).
