Questions and answers

When was the first Earth Day?

April 22, 1970, a Wednesday. An estimated 20 million Americans took part in rallies, marches and teach-ins that day.

Who started Earth Day?

Senator Gaylord Nelson of Wisconsin proposed a nationwide environmental teach-in for April 22, 1970. A year earlier the peace activist John McConnell had proposed a day to honor the Earth, first observed on March 21, 1970.

Why is Earth Day on April 22?

Senator Nelson wanted college students to take part. The week of April 19 to 25 did not fall during exams or spring breaks, and a Wednesday had less competition from other events.

Are these Earth Day questions suitable for a class?

The pack is written for a general table and has nothing unsuitable for children, but it is history, not a science lesson: names, dates and places.

How this list was compiled

Written for this site; nothing was copied from another list. Questions and wrong choices are our own. Each explanation restates, in our own sentences, a fact from the English Wikipedia article named and linked beside the question (https://en.wikipedia.org, text under the Creative Commons Attribution-ShareAlike 4.0 license): Earth Day. The text of each article was fetched on October 2 or 3, 2026, and on October 3, 2026 the passage that states each fact was read in it before the question was kept. The pack is about the day itself: how it began, the first Earth Day of 1970, the years since and the equinox Earth Day kept at the United Nations. Left out on purpose: living people (the national coordinator of 1970 is not named), company and product names, titles of books and songs, counts of people that change from year to year, and forecasts about the climate. Levels are our estimate: easy is fair for any table, medium suits people who know the subject, hard will stump most tables. Each question also carries the date its article was read (checkedOn).
