Earth & Life Science Quiz: Test Your Knowledge of Biology and Geology
Want to brush up on biology, geology, or ecology in a fun way? This earth and life science quiz covers the major topics: cells, DNA, chromosomes, evolution, ecosystems, tectonic plates, volcanoes, earthquakes, and climate. Ninety questions spread across three difficulty levels, from middle school to high school level. Every answer comes with an explanation and a source. You play right in your browser, no sign-up required, and you'll find all our quizzes in the science quizzes section.
Cells, DNA, and Genetics
The cell is the basic unit of life. In this quiz, you'll explore the role of the nucleus, chromosomes, and DNA. You'll revisit mitosis, meiosis, and the mechanisms behind hereditary traits. The harder questions cover introns, exons, and DNA replication—great for building a solid foundation in genetics before a test or exam.
Evolution and Biodiversity
Darwin, natural selection, genetic drift, mass extinctions: evolution sits at the heart of the life sciences. This quiz will test you on the mechanisms behind the diversity of life. You'll also come across questions on ecosystems, food chains, and biogeochemical cycles like the nitrogen cycle. A great way to understand how species interact with their environment.
Geology: Plates, Volcanoes, and Earthquakes
Earth is a dynamic planet. You'll be tested on the planet's internal structure, plate tectonics, mid-ocean ridges, and subduction zones. Questions also cover igneous, sedimentary, and metamorphic rocks. Finally, you'll learn about the Mohorovičić discontinuity and earthquake measurement scales.
A Timeline Format for a Change of Pace
Want to spice up your session? Try the timeline quiz: you'll put events in order, from geological eras to major scientific discoveries. A great way to memorize key milestones while racing against the clock.
Score, Timer, and Overall Leaderboard
Every quiz shows your final score and response time. You can compare your performance with other players on the overall leaderboard. And for a daily challenge, check out the quiz of the day: ten new questions every morning, covering all topics.
