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.

2024年8月20日 · Between about 53 miles (85 km) and 375 miles (600 km) lies the thermosphere, known as the upper atmosphere. While still extremely thin, the gases of the thermosphere become increasingly denser as one descends toward the Earth.

2024年5月13日 · “The Earth’s atmosphere allows life to exist. . . like a protective bubble that surrounds the planet,” stated Ueyama. Although we cannot directly see the atmosphere, it provides the air we breathe and protects us from harmful ultraviolet (UV) rays. The atmosphere also works to trap heat and maintain moderate, habitable temperature ranges.

2025年1月6日 · atmosphere, the gas and aerosol envelope that extends from the ocean, land, and ice -covered surface of a planet outward into space.

Atmospheres are clouds of gas bound to and engulfing an astronomical focal point of sufficiently dominating mass, adding to its mass, possibly escaping from it or collapsing into it.

2024年7月2日 · The atmosphere is a layer of gas and suspended solids extending from the Earth's surface up many thousands of miles, becoming increasingly thinner with distance but always held by the Earth's gravitational pull.

2021年9月8日 · The term weather describes the state of the atmosphere at a given point in time and geographic location. Weather forecasts provide an estimate of the conditions we expect to experience in the near future and are based on statistical models of similar conditions from previous weather events.

Use mathematical formulas to define atmospheric temperature, pressure, and density; Compute pressure and density changes with altitude; Describe the vertical structure of Earth’s atmosphere; Define and apply the ideal gas law; Describe hydrostatic balance; Discuss the difference between weather and climate

2024年5月24日 · Figure 3.2.1 3.2. 1 illustrates the way in which the atmosphere is divided using temperature change as the primary criterion. The troposphere is the layer closest to the Earth's surface. The graph of temperature change indicates that air temperature decreases with an increase in altitude through this layer.

2024年12月14日 · Atmospheric structure refers to the state of the air at different heights. The true vertical structure of the atmosphere varies with time and location due to changing weather conditions and solar activity.
