25 cze 2024 · Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions. We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet.
6 paź 2023 · Scientists divide the atmosphere into 5 different layers based on factors like air pressure and density. The names of these layers, in order of lowest to highest, are: Troposphere; Stratosphere; Mesosphere; Thermosphere; Exosphere
1 gru 2020 · The atmosphere extends from Earth’s surface to more than 10,000 kilometers (6,200 miles) above the planet. Those 10,000 kilometers are divided into five distinct layers. From the bottom layer to the top, the air in each has the same composition. But the higher up you go, the further apart those air molecules are.
19 paź 2023 · Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.
20 sie 2024 · The envelope of gas surrounding the Earth changes from the ground up. Five distinct layers have been identified using thermal characteristics (temperature changes), chemical composition, movement, and density.
6 sty 2020 · Airglow carries information about the temperature, density, and composition of the upper atmosphere, and also helps us trace how particles move through the region. The Ionospheric Connection Explorer (ICON) was launched in October 2019 to study the uppermost reaches of the atmosphere, particularly airglow.
The atmosphere is a mixture of gases that surrounds the Earth. It helps make life possible by providing us with air to breathe, shielding us from harmful ultraviolet (UV) radiation coming from the Sun, trapping heat to warm the planet, and preventing extreme temperature differences between day and night.
