Oct 19, 2023 · Earth’s atmosphere stretches from the surface of the planet up to as far as 10,000 kilometers (6,214 miles) above. After that, the atmosphere blends into space. Not all scientists agree where the actual upper boundary of the atmosphere is, but they can agree that the bulk of the atmosphere is located close to Earth’s surface—up to a ...

Oct 2, 2019 · Located between about 700 and 10,000 kilometers (440 and 6,200 miles) above Earth’s surface, the exosphere is the highest layer of Earth’s atmosphere and, at its top, merges with the solar wind. Molecules found here are of extremely low density, so this layer doesn’t behave like a gas, and particles here escape into space.

How does the atmosphere affect the temperature of the Earth?
The atmosphere of Earth creates pressure, absorbs most meteoroids and ultraviolet solar radiation, warms the surface through heat retention (greenhouse effect), and reduces temperature extremes between day and night (the diurnal temperature variation), maintaining conditions allowing life and liquid water to exist on the Earth's surface.
Jan 6, 2020 · ICONic Views of the Atmosphere. JPEG. In the upper reaches of the atmosphere, at the boundary between Earth and space, particles and gases and energy do an intricate and colorful dance that varies daily. A new satellite is watching that dance close up.
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.
Jul 23, 2023 · Earth's atmosphere extends from the surface to a height of around 10,000 km [6,213 miles]. Most of the air mass is confined to the lower part of the atmosphere and the higher the thinner of...
The five principal layers of the atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Troposphere: The troposphere is the layer closest to Earth. It is the densest layer (i.e., contains the most air particles), and is where most of Earth’s weather and cloud formation occurs. The troposphere is heated ...
