Atmospheric Sciences
Atmospheric science is the study of the atmosphere, its processes, and the interaction of the atmosphere with other systems, including the effects other systems have on the atmosphere and visa versa. Fields in Atmospheric Sciences include Meteorology, Climatology, and Aeronomy. Ask and answer questions about Atmospheric Sciences in this category.

What are the benefits of global warming to farmers?
Some potential benefits of global warming for farmers include longer growing seasons, increased crop yields in certain regions, and expanded opportunities to grow new types of crops. However, these benefits may be offset by negative effects such as more frequent and severe weather events, changes in pest and disease patterns, and water scarcity.
When can you see the Aurora Borealis and the Aurora Australis?
The Aurora Borealis (North) and Aurora Australis (South) have roughly a 2500 mile radius limit from their magnetic poles, although the phenomenon occurs on the perimeter of a more elliptical shape (the auroral oval).
This distance and the vivacity varies with the energy of the solar storm temporarily expanding in to temperate latitudes on occasions, and even visible to equatorial regions roughly once a decade (due to the 11 year sun spot cycle), although a common occurrence in the polar regions and regularly visible in Canada/ Alaska, far Northern Europe and Asia (Borealis) and South America and south Australasia (Ausralis).
The Aurora is essentially only visible by night and when it is clear and dark (free from light pollution), and it is most active around midnight (the opposite side to the sun due to the geometry of the magnetic field and solar winds). The Geomagnetic storms that ignite auroras occur most during the months close to the equinoxes. This is due to the IMF (Interplanetary Magnetic Field -coming from the sun) linking up with Earths magnetic field in a specific geometric way that allows an easy flow of particles in to the earths inner magnetosphere. The Suns IMF is spiraled due to the suns rotation and it is during April and October (the equinoxes) that the earth's magnetic axis align with this spiral.
This, however, is not the only influence on geomagnetic activity, also because the suns rotation axis is tilted (8 degrees in comparison to earths orbit) the speed of the solar winds from the sun rise and decline in a 6 month cycle, with the strongest winds by about 12% (50km/s) occurring early September and early March. In solar storms, however, the speed can increase many times, as can the IMF.
What gases are in the atmosphere?
Nitrogen and oxygen are the two most important gases. They comprise about 78 and 21 % of the air respectively. There are also variable amounts of water vapour, about 0.93% argon, 0.04% carbon dioxide and trace amounts of other gases, both natural and polluting.
nitrogen - 78.084%
oxygen - 20.946%
argon - 0.934%
water vapour - 0.4%
carbon dioxide - 0.04%
neon - 0.01818%
helium - 0.000524%
methane - 0.000179%
krypton - 0.000114%
hydrogen - 0.000055%
nitrous oxide - 0.00003%
carbon monoxide - 0.00001%
xenon - 0.000009%
ozone - 0.000007%
nitrogen dioxide - 0.000002%
iodine - 0.000001%
ammonia - trace
There are several gases present in the atmosphere
- Nitrogen-78%

What may form when moisture condenses on small particles in the atmosphere?
The sky is everything you can see above you when looking up. It is the atmosphere that we see from the surface of the Earth.
The universe, however, is immensely large.
What is the temperature of the Equator?
The Equator generally experiences high temperatures due to its proximity to the sun. Average temperatures can range from 25°C to 30°C (77°F to 86°F) throughout the year. However, temperatures can vary depending on the time of day, season, and specific location along the Equator.
Which gas makes up 0.04 percent of the atmosphere?
Carbon dioxide in 2014 made up 0.04% of the atmosphere. This figure is rising every year.
Which is an interaction between the geosphere and the biosphere that damages the atmosphere?
Deforestation is an example of an interaction between the geosphere and the biosphere that can damage the atmosphere. When trees are removed, it can lead to an increase in greenhouse gas emissions, such as carbon dioxide, which contributes to climate change and air pollution.
it is the ozone layer in the atmosphere because it is what keeps the atmosphere in check of what is happening in the atmosphere.
What are the possible sources of heat for the atmosphere?
Heat from the sun and radiant heat from the core of the earth (caused by the molten core and by radioactive decay) The Green house gases (GHG) like water vapor and CO2 will trap some of the heat making the earth warm enough to support life (~15C instead of ~-18C)
Which of the following removes carbon from the atmosphere?
Photosynthesis is the process that removes carbon from the atmosphere. Plants, algae, and some bacteria use sunlight to convert carbon dioxide into sugars and oxygen, helping to reduce the amount of CO2 in the air.
The Earth's surface is constantly changing due to weathering, erosion, and tectonic activity, which can obscure or erase evidence of a meteoroid impact over time. Additionally, many impacts occur in remote areas like the ocean or uninhabited regions, making it less likely for people to observe or document them. Finally, smaller meteoroids often burn up in the atmosphere before reaching the surface, leaving no visible impact evidence.
Which function is performed by earth’s atmosphere?
Earth's temperature is raised and moderated by trapping in heat.
Earth is definitely not safe, it's just the safest place we can live.
Noy at all.if you have heard of plate margins then u will understand.even though at some place crust forms due to plate margins moving apart or diverging but at other places old crust gets destroyed.it occurs when one plate mis pulled under thwe other due to compressional forces and then one plate on which too much stress acts gets destroyed In a sense, the earth is indeed growing. Every year, we collect tons of material that falls from space.
Why is the aurora borealis often seen in “the northern latitudes of Canada”?
Spectacular aurora, or northern lights, seen by Colin Chatfield in Saskatchewan, Canada. Bottom line: When charged particles from the sun strike atoms in Earth's atmosphere, they cause electrons in the atoms to move to a higher-energy state.
The outermost layer of Earth's atmosphere is the exosphere. This layer is where the atmosphere is the thinnest, gradually transitioning into space. The exosphere is composed mostly of hydrogen and helium atoms.
If more heat is trapped in the atmosphere how will the earths temperaturr change ?
If more heat is trapped in the atmosphere, the Earth's temperature will increase, leading to global warming. This can result in more extreme weather events, rising sea levels, and disruptions to ecosystems and wildlife. It is crucial to reduce greenhouse gas emissions to mitigate these effects.
What would happend if water could not condense in the atmosphere?
We wouldn't have any clouds or precipitation!
