3 days ago · The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by Earth's gravity.
2 days ago · The composition of the atmosphere is more or less constant with height to an altitude of about 100 km (60 miles), with particular exceptions being water vapour and ozone. The atmosphere is commonly described in terms of distinct layers, or regions.
3 days ago · There are two primary reasons for the pulsing: First, fires have a clear day-night cycle. They typically flare up during the day and die down at night. Second, you’re seeing the absorption and release of carbon dioxide as trees and plants photosynthesize. Earth’s land and oceans absorb about 50% of carbon dioxide; these are natural carbon ...

5 days ago · Our atmosphere has five primary layers which make life possible. The first, the troposphere, extends from sea level to about 11 miles (17 kms) up at the Equator. Most of our weather happens here due to the mixture of warm air rising and falling to form clouds and wind.
3 days ago · Venus has the most massive atmosphere of the terrestrial planets, which include Mercury, Earth, and Mars. Its gaseous envelope is composed of more than 96 percent carbon dioxide and 3.5 percent molecular nitrogen .
3 days ago · The data contains concentrations of carbon dioxide in the atmosphere from hundreds of thousands of years ago through 2021, measured in parts per million (ppm). The data come from a variety of historical ice core studies and recent air monitoring sites around the world.
