Amazon Rainforest Quiz
Pink river dolphins, indigenous tribes, the meeting of the waters — how well do you know the world's largest rainforest?
Pink river dolphins, indigenous tribes, the meeting of the waters — how well do you know the world's largest rainforest?
The Amazon rainforest covers up to 7 million km² across nine countries and is home to roughly 10% of all known species on Earth. The Amazon River discharges more water than the next 7 biggest rivers combined — and there's a 'meeting of the waters' near Manaus where the black Negro flows beside the muddy Solimões for 6 km without mixing. This 50-question quiz covers the river, biodiversity, indigenous peoples, and deforestation.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll explore the Amazon River and its tributaries, Brazil's Manaus and Peru's Iquitos, jaguars and pink river dolphins, indigenous groups like the Yanomami and Kayapó, the rubber boom, deforestation drivers, conservation activists like Chico Mendes, and the Amazon's role as a global carbon sink.
The Amazon rainforest is the world's largest tropical rainforest, covering 5.5-7 million km² across nine countries. About 60% of it sits in Brazil, with significant areas in Peru, Colombia, and beyond.
The Amazon is approximately 6,400-6,992 km long depending on the measurement, making it either the longest or second-longest river in the world after the Nile. It's clearly the largest by discharge — about 209,000 m³/s.
Roughly 17% of the Amazon — about 800,000 km² — has already been lost. Deforestation peaked under President Bolsonaro (2019-2022) and has been declining under Lula since 2023, driven mainly by cattle ranching, soybeans, and illegal logging.
