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.

How does the atmosphere composition today compare with the air 1000 years ago?
The composition of the atmosphere today is different compared to 1000 years ago due to human activities. The increase in greenhouse gases such as carbon dioxide has led to global warming and climate change. This change in composition is impacting the Earth's climate and ecosystem.
What layer does reah the highest altitude?
The layer that reaches the highest altitude in the Earth's atmosphere is the exosphere. It extends from about 700 km (440 miles) above the Earth's surface and gradually transitions into space.
What are the different gasses that are found in the atmosphere?
The Earth's atmosphere is primarily composed of nitrogen (about 78%) and oxygen (about 21%). Other gases include argon, carbon dioxide, and trace amounts of water vapor, methane, and ozone. These gases play a crucial role in regulating the Earth's climate and supporting life.
Meteors themselves do not have an atmosphere. They are objects that enter the Earth's atmosphere, where they burn up due to friction with the air. The bright streak of light that is produced is known as a meteor or shooting star.
What are the conditions of the atmosphere called?
The conditions of the atmosphere are called weather. Weather includes elements like temperature, precipitation, humidity, wind speed, and atmospheric pressure. It is the day-to-day variations in these conditions that make up the weather of a particular location.
Is there a boundary between the atmosphere and space?
Yes, the boundary between Earth's atmosphere and outer space is known as the Kármán line, located approximately 62 miles (100 kilometers) above sea level. This is where the atmosphere becomes too thin to support conventional aircraft flight and space vehicles must start using rocket propulsion to maintain their altitude.
Why do satellites burn up when it hits the atmosphere?
Because before they hit the atmosphere they are travelling at extremely high speeds without any resistance (from wind). Therefore when they enter the atmosphere the wind resistance builds up and creates friction which also brings lots of heat, causing them to burn up before they hit the ground. This doesn't just happen to satellites; most if not all objects travelling from space into Earth encounter this. The only exception would be space shuttles because they have been specially designed with heat resistant panels etc.
What would happen if there would be no atmosphere?
If there was no atmosphere, there would be no air for us to breathe, leading to suffocation and the inability for life to exist on Earth. Additionally, the lack of atmosphere would result in extreme temperature fluctuations between day and night, and increased exposure to harmful solar radiation.
Is tromosphere divided into ionosphere and exosphere?
No, the atmosphere is divided into the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The ionosphere is a region within the thermosphere where gas molecules become ionized by solar radiation, while the exosphere is the outermost layer of Earth's atmosphere where the air is extremely thin and merges with outer space.
A tornado is a funnel-shaped spinning cloud that acts like a vacuum cleaner, sucking up debris and objects as it moves through a town. Tornadoes can cause significant damage and are associated with severe weather conditions.
What does it mean when you walk in the room and the atmosphere changes?
When you walk into a room and the atmosphere changes, it could mean that your presence is noticed and has an impact on the people in the room. This could be due to your energy, emotions, or body language affecting the mood and dynamics of the space.
What sort of temperatures would you experience in the mesophere?
the mesosphere is ~35km thick ranging from 50km above the surface to 85km above the surface. the temperature changes rather linearly from 0 degrees at the start of the mesosphere and falls to nearly -100 degrees at the top of the mesosphere
How far away is the Ionosphere from earth surface?
The ionosphere starts at an altitude of about 48 kilometers (30 miles) above the Earth's surface and extends upwards to about 965 kilometers (600 miles).
What is the marine type of climate?
A marine climate is typically characterized by mild temperatures year-round, due to the moderating influence of the nearby ocean. It often experiences high humidity and consistent precipitation, with wet winters and drier summers. Marine climates are common along coastal regions with cool ocean currents.
What is the difference between the aneroid barometer and a mercury barometer?
An aneroid barometer measures air pressure using a flexible metal box called an aneroid cell, whereas a mercury barometer uses a column of mercury to measure air pressure. Aneroid barometers are more portable and do not use toxic mercury like mercury barometers.
Why is the tropsphere the most dense part in the atmosphere?
The troposphere is the most dense part of the atmosphere because it is closest to the Earth's surface where gravity pulls air molecules downward, compressing them together. The weight of the air above also contributes to the high density in the troposphere.
Does Lightning clean the atmosphere?
Yes, lightning can help clean the atmosphere by producing ozone, which can break down pollutants and improve air quality. Additionally, lightning can also trigger chemical reactions that help remove pollutants from the air.
What is the word triangle for atmosphere?
The word triangle for atmosphere would be "hydrosphere, lithosphere, atmosphere."
What is the strong steady wind high in the atmosphere?
The strong, steady wind high in the atmosphere is called the jet stream. It is a narrow band of fast-flowing air located in the upper levels of the troposphere, typically found at altitudes of 9-16 km (30,000-52,000 feet). Jet streams play a key role in shaping weather patterns and can influence the movement of storms and aircraft.
Would saturns atmosphere crush people?
Yes, Saturn's atmosphere is mostly composed of hydrogen and helium gases, making it very thick and dense. The high pressure and extreme temperatures on Saturn would crush and vaporize a person long before they reached the planet's surface.
How many Tsar Bomba size nuclear explosions would be required to cause a nuclear winter?
It depends on where they are set off, as nuclear winter is precipitated mostly by the transfer of materials such as smoke and soot from flammable cities (not just nuclear materials) from the blast site into the upper atmosphere.
The Tsar Bomba detonation was scaled back from 100 megatons to 50 megatons to mitigate nuclear fallout, not nuclear winter, and it was not detonated over a city.
It is estimated, from a 2007 study, that one third of the world's arsenal could release 50 Tg (teragrams) of smoke, and reduce global temperatures by -3°C to -4°C for years, with half that shift persisting for more than a decade. There might be more than a -20°C shift in North America, and more than -15°C in Eurasia, covering all agricultural areas.
This would be comparable to the ice age of 18,000 years ago, and would devastate the planet. Even a "small" conflict, involving "50 Hiroshima scale weapons", less than 100 kilotons each, very small in comparison to today's weapons, would be terrible. The study has been criticized, but I believe it to be accurate.
What part of body directly accepts oxygen from atmosphere?
The lungs are responsible for directly accepting oxygen from the atmosphere during the process of breathing. Oxygen is taken in through the lungs' alveoli, which are tiny air sacs where gas exchange occurs, allowing oxygen to enter the bloodstream and carbon dioxide to be released.
How does atmosphere act like a glass house?
The atmosphere acts like a glass house by trapping heat from the Sun within the Earth's surface, similar to how glass traps heat inside a greenhouse. This phenomenon, known as the greenhouse effect, helps regulate the Earth's temperature and keeps it suitable for life. However, human activities that release greenhouse gases can enhance this effect, leading to global warming.
How fast does the sun travel over the earth?
The sun does not travel over the earth. The earth turns "under" the sun. As a result, the sun appears to move across the sky a the rate of about 15 degrees per hour
