WebMost of the Earth's atmosphere (80 to 90%) is found in the troposphere, the atmospheric layer where we live. This layer, where the Earth's weather occurs, is within about 10 km (6 miles) of the Earth's surface. The stratosphere goes up to about 50 km (31 miles). Gravity is the reason the atmosphere is denser closer to the Earth's surface. WebSep 18, 2024 · Earth’s atmosphere stretches for about 600 miles, so technically if space is the absence of an atmosphere, then everything within 600 miles including the …
Atmosphere of Earth - Wikipedia
In this way, Earth's atmosphere can be divided (called atmospheric stratification) into five main layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The altitudes of the five layers are as follows: Exosphere: 700 to 10,000 km (440 to 6,200 miles) Thermosphere: 80 to 700 km (50 to 440 miles) See more The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth creates pressure, absorbs most See more In general, air pressure and density decrease with altitude in the atmosphere. However, the temperature has a more complicated profile … See more Pressure and thickness The average atmospheric pressure at sea level is defined by the International Standard Atmosphere as 101325 pascals (760.00 Torr; 14.6959 psi; 760.00 mmHg). This is sometimes referred to as a unit of standard atmospheres (atm) See more Atmospheric circulation is the large-scale movement of air through the troposphere, and the means (with ocean circulation) by which heat is … See more The three major constituents of Earth's atmosphere are nitrogen, oxygen, and argon.
