Wednesday, April 22, 2020, is the 50th anniversary of Earth Day. This year’s theme is climate action. Because of the global coronavirus pandemic, it seems that air quality is improving as more people stay off the roads. Roya Bahreini is an associate professor of atmospheric science at the University of California, Riverside. She said this improvement of air quality is happening here in the United States and across the world with lockdowns in place.

Satellite images are showing this significant improvement in air quality. Levels of nitrogen dioxide (NO₂), one of many common pollutants that make up the Air Quality Index (AQI) used by the Environmental Protection Agency (EPA) has shown a decrease in Southern California from March 15-April 14 in 2019 compared to 2020.

Introduction


Three centuries ago, the English scientist Isaac Newton calculated, from his studies of planets and the force of gravity, that the average density of the Earth is twice that of surface rocks and therefore that the Earth’s interior must be composed of much denser material. Our knowledge of what’s inside the Earth has improved immensely since Newton’s time, but his estimate of the density remains essentially unchanged. Our current information comes from studies of the paths and characteristics of earthquake waves travelling through the Earth, as well as from laboratory experiments on surface minerals and rocks at high pressure and temperature. Other important data on the Earth’s interior come from geological observation of surface rocks and studies of the Earth’s motions in the Solar System, its gravity and magnetic fields, and the flow of heat from inside
