Earth's atmosphere

The Earth's atmosphere is the layer of gasses around the Earth. It is held in place by Earth's gravity. It is today made up mainly of nitrogen (78.1%)...

Air is the Earth's atmosphere. Air is a mixture of many gases and tiny dust particles. It is the clear gas in which living things live and breathe. It...

lowest layer of the Earth’s atmosphere. It extents up to 20 kilometers above the earth’s surface. It contains 75% of the atmosphere's mass and 99% of the...

800 mi) beneath the Earth's surface. The transition between the inner core and outer core is about 5,150 km (3,200 mi) beneath the Earth's surface. The temperature...

All observation of space from Earth is filtered through the Earth's atmosphere. The atmosphere filters and distorts what is seen and recorded. Satellite-based...

collisionless. In the case of bodies with substantial atmospheres, such as Earth's atmosphere, the exosphere is the uppermost layer, The lightest atmospheric...

at earth’s atmosphere first and then earth's surface. The heat comes from solar energy. Insolation is the solar radiation that reaches the earth's surface...

problem that hasn't been solved is that the noble gas isotope ratios of Earth's atmosphere are different than those of its mantle. This might mean they were...

space telescopes are in LEO since they only have to be above the Earth's atmosphere. The International Space Station is in LEO. This short article about...

The mesosphere is a part of the atmosphere. It is between the stratosphere and the thermosphere. On Earth, the mesosphere starts at 50 kilometers above...

The greenhouse effect occurs when certain gases in the Earth's atmosphere (the air around the Earth) trap infrared radiation. This makes the planet become...

The tropopause is a boundary region in Earth's atmosphere between the troposphere and the stratosphere. Here the air ceases to cool at -56.5°C (-70°F)...

The thermosphere is the fourth layer of the Earth's atmosphere. It is directly above the mesosphere (middle layer) and directly below the exosphere (top...

the planet. In some cases NEOs hit the Earth. Most of these meteors explode harmlessly in the upper atmosphere. But some NEOs are dangerous. We try to...

Atmospheric chemistry is a branch of science in which the chemistry of the Earth's atmosphere and that of other planets is studied. It is a multidisciplinary field...

Meteorology is the science that focuses on the Earth's atmosphere. People who study meteorology are called meteorologists. Meteorologists record air pressure...

climatology by calculating temperatures of the upper layers of the Earth's atmosphere as well as the temperature conditions on planets of the inner Solar...

exists beyond Earth and its atmosphere. On Earth, space begins at the Kármán line (100 km above sea level). This is where Earth's atmosphere is said to stop...

Earth sciences include the study of the atmosphere, oceans and biosphere, as well as the solid earth. Typically Earth scientists use ideas from physics, chemistry...
