Quick explanations for the trickiest answers
Questions 1–5: Earth Day is observed on April 22, and the first Earth Day took place in 1970. The U.S. Environmental Protection Agency records that Senator Gaylord Nelson helped create the event and that approximately 20 million Americans participated. Congress authorized the EPA later that year.[3]
Questions 6–9: Google’s official Doodle archive describes a Doodle as a celebration presented through a change to the Google logo. The 2015 Earth Day Doodle offered an animal personality quiz, while the 2024 Doodle used aerial imagery to spotlight natural beauty, biodiversity, and conservation locations.[1] [2]
Questions 26–35: Corals are animals that can live in partnership with microscopic algae. NOAA explains that warming water can cause bleaching and that increased carbon dioxide contributes to ocean acidification. NOAA also notes that about 25% of marine species are found in coral reef ecosystems.[4] [5]
Questions 36–45: Carbon dioxide from human activities is a major driver of climate change. Renewable sources such as wind and solar produce little to no greenhouse-gas emissions during operation, while recycling can conserve energy and natural resources. These principles are summarized by the United Nations and the U.S. Energy Information Administration.[6] [7]
Questions 48–49: Google’s Earth Day 2024 Doodle featured the Great Green Wall in Nigeria and Vatnajökull National Park in Iceland, along with other conservation locations around the world.[2]

Frequently Asked Questions About the Google Earth Day Quiz
Is this the official Google Earth Day quiz?
Google has published official Earth Day Doodles, including the 2015 animal personality quiz. This page is an original 50-question earth day quiz Google-style resource created for learning and entertainment. It is not presented as an official Google product, and the availability of an interactive Google Doodle may change over time.[1]
How can I find an Earth Day quiz on Google?
Search for “Earth Day quiz,” “earth day quiz on Google,” or “Google quiz Earth Day.” You may find current seasonal content, archived Google Doodles, classroom resources, or independently published trivia. Check the publisher and date so you know whether you are viewing an official Google Doodle or a third-party quiz.
How many animals are on the Google Earth Day quiz?
The original Google Earth Day 2015 experience was a short animal personality quiz, but the official Doodle archive page does not define one permanent number of animal outcomes in the way a standard answer sheet does. Different pages may also use “Google Earth Day quiz” to describe different versions. For that reason, this article does not claim a fixed number of animals. Instead, it provides 50 transparent, checkable quiz questions on Earth Day.[1]
How do I get coral in the Google Earth Day quiz?
There is no universal coral reward or coral outcome documented on the official Google Earth Day 2015 Doodle page. The coral question may refer to a different game, a social-media quiz, or a third-party version. In the quiz above, coral appears as an educational topic in Questions 26–35, where the answer key explains coral animals, bleaching, reefs, and ocean acidification.
Can I use this Earth Day trivia quiz in a classroom?
Yes. Teachers can assign all 50 questions, select one section, or ask students to answer in teams. For younger learners, read the choices aloud and discuss why an answer is correct. For older learners, use the references to compare the quiz with primary sources and ask students to research a local conservation issue.
What is the best way to improve my score?
Review the explanations for the questions you missed, then retake the quiz without looking at the answer key. Next, choose one subject—such as coral reefs, biodiversity, renewable energy, or recycling—and learn from a reliable scientific or government source. Knowledge becomes more meaningful when it leads to a practical, measurable habit.
Final Takeaway
This Google Earth Day quiz brings together the topics people commonly search for around Earth Day: animal trivia, Google Doodles, coral reefs, climate change, biodiversity, and practical sustainability. Whether you searched for google earth day quiz answers, an earth day quiz Google experience, or a ready-to-use set of Earth Day trivia questions, the goal is the same: learn something accurate, share it with others, and protect the planet beyond one day of the year.
