The sun's atmosphere: Photosphere, chromosphere and corona "Based on the detected events, we estimate that at least 11,000 swirls are present on the sun at all times," Sven Wedemeyer-Bhm, a solar scientist at the University of Oslo in Norway and lead author of the team that identified tornados on the sun, told Space.com (opens in new tab). 1996 - 2023 National Geographic Society. Giant super-tornados may also play a role in heating the sun's outer layer. Text on this page is printable and can be used according to our Terms of Service. It is 11-12 miles (18-20 km) high at the equator, 5 miles (9 km) at 50Nand 50S, and just under four miles (6 km) high at the poles. National Oceanic and Atmospheric Administration, The Positive and Negative Side of Lightning, Tsunami Preparedness and Mitigation: Individuals (You! We and our partners use cookies to Store and/or access information on a device. Mercurys atmosphere contains only a thin exosphere dominated by hydrogen, helium, and oxygen. When you're roasting a marshmallow you move it closer to the fire to cook it, not farther away.". Fast winds separate light-colored bands, called zones, from dark-colored bands, called belts. It extends upward to a height of about 85 km (53 miles) above our planet. It extends from the top of the thermosphere to 6,200 miles (10,000 km) above the earth. The density of matter at the base of the corona is 109 atoms / cm2, a value that is 10-10 times the density of the Earth's atmosphere at sea level. It starts at about 80 km upwards to about 550 km altitude. Theorganiccomponents of the biosphere, including plant and animalremains, mix with these eroded rocks to createfertilesoilthe pedosphere. Elves are dim, halo-shaped discharges that appear even higher in the mesosphere.IonosphereThe ionosphere extends from the top half of the mesosphere all the way to the exosphere. The lithosphere is the solid, outer part of Earth, including the brittle upper portion of the mantle and the crust. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent. You cannot download interactives. The ozone layer serves a vital role in the protection of our planet, as the molecules of ozone prevent ultraviolet light from the Sun to hit our planet without stopping. Take it to the MAX! NY 10036. The air in this layer is absolutely not friendly for us, as it would be impossible to breathe in the mesosphere because of too low oxygen levels. Exosphere Facts - Science Struck In this layer, atoms and molecules escape into space and satellites orbit the earth. The atmosphere surrounds our planet like the peel of an orange. The transition layer at the bottom of the stratosphere is called the tropopause. Thermosphere Our Sun is surrounded by a jacket of gases called an atmosphere. This prevents convection as there is no upward vertical movement of the gases. Only the lightest gasesmostly oxygen, helium, and hydrogenare found here.The thermosphere extends from the mesopause (the upper boundary of the mesosphere) to 690 kilometers (429 miles) above the surface of the Earth.
