Earth Day Quiz


 

Hey everyone! On April 22, we celebrate Earth Day. As this date was a few days ago, we have prepared a quiz that tests your knowledge about our planet! Check how many facts you know and how many points you can get!

Earth Day is an annual event on April 22 to demonstrate support for environmental protection. First held on April 22, 1970, it now includes a wide range of events coordinated globally by EarthDay.org including 1 billion people in more than 193 countries. The official theme for 2022 was Invest In Our Planet.

In 1969 at a UNESCO Conference in San Francisco, peace activist John McConnell proposed a day to honor the Earth and the concept of peace, to first be observed on March 21, 1970, the first day of spring in the northern hemisphere. This day of nature’s equipoise was later sanctioned in a proclamation written by McConnell and signed by Secretary-General U Thant at the United Nations. A month later, United States Senator Gaylord Nelson proposed the idea of ​​holding a nationwide environmental teach-in on April 22, 1970. He hired a young activist, Denis Hayes, to be the National Coordinator. Nelson and Hayes renamed the event “Earth Day”. Denis and his staff grew the event beyond the original idea for a teach-in to include the entire United States. More than 20 million people poured out on the streets, and the first Earth Day remains the largest single-day protest in human history. Key non-environmentally focused partners played significant roles. Under the leadership of labor leader Walter Reuther, for example, the United Auto Workers was the most instrumental outside financial and operational supporter of the first Earth Day. According to Hayes, “Without the UAW, the first Earth Day would have likely flopped!” Nelson was later awarded the Presidential Medal of Freedom award.

Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth’s surface is made up of the ocean, dwarfing Earth’s polar ice, lakes, and rivers. The remaining 29% of Earth’s surface is land, consisting of continents and islands. Earth’s surface layer is formed of several slowly moving tectonic plates, interacting to produce mountain ranges, volcanoes, and earthquakes. Earth’s liquid outer core generates the magnetic field that shapes Earth’s magnetosphere, deflecting destructive solar winds.

Earth’s atmosphere consists mostly of nitrogen and oxygen. More solar energy is received by tropical regions than polar regions and is redistributed by atmospheric and ocean circulation. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. A region’s climate is governed by latitude, but also by elevation and proximity to moderating oceans. Severe weather, such as tropical cyclones, thunderstorms, and heatwaves, occurs in most areas and greatly impacts life.

Earth is an ellipsoid with a circumference of about 40,000 km. It is the densest planet in the Solar System. Of the four rocky planets, it is the largest and most massive. Earth is about eight light minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution. Earth rotates around its own axis in just less than a day (in about 23 hours and 56 minutes). Earth’s axis of rotation is tilted with respect the perpendicular to its orbital plane around the Sun, producing seasons. Earth is orbited by one permanent natural satellite, the Moon, which orbits Earth at 380,000 km (1.3 light seconds) and is roughly a quarter as wide as Earth. The Moon always faces the Earth on the same side through tidal locking and causes tides, stabilizes Earth’s axis, and gradually slows its rotation.

Earth formed over 4.5 billion years ago. During the first billion years of Earth’s history, the ocean formed, and then life developed within it. Life spread globally and began to affect Earth’s atmosphere and surface, leading to Earth’s Great Oxidation Event two billion years ago. Humans emerged 300,000 years ago, and have reached a population of almost 8 billion today. Humans depend on Earth’s biosphere and natural resources for their survival but have increasingly impacted Earth’s environment. Today, humanity’s impact on Earth’s climate, soils, waters, and ecosystems is unsustainable, threatening people’s lives and causing widespread extinction of other life.
