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.

Why do you sometimes need to maintain an atmosphere of silence?

To maintain an atmosphere of silence, you need a way to cancel out the generated sound capacity of any particular sounds that contribute to noise in a given environment. A noise cancellation device would be quite effective.

What makes up 1 percent of Earth's atmosphere?

1 percent of the earths atmosphere is made of the following:

- Argon (0.93%)

- Carbon dioxide (0.03%)

- Neon> trace

- Helium> trace

- Methane> trace

- Krypton> trace

- Xenon> trace

- Hydrogen> trace

- Ozone> trace

21% of earths atmosphere is made of oxygen

78% of earths atmosphere is made of nitrogen

How does the climate of seattle compare with the climate of Spokane?

Seattle has a milder and wetter maritime climate, with cool, damp winters and mild, dry summers. Spokane, on the other hand, has a semi-arid climate with greater temperature extremes, including hot summers and cold winters, and less precipitation overall compared to Seattle.

Is the air thicker in more humid air?

Yes, humid air is denser than dry air because water vapor molecules have a higher mass than nitrogen and oxygen molecules found in air. This can make it seem like the air is thicker when it is more humid.

A common gas in your atmosphere essential for plants?

Carbon dioxide is a common gas in Earth's atmosphere that is essential for plants. Through the process of photosynthesis, plants use carbon dioxide to produce energy in the form of glucose, releasing oxygen as a byproduct. This exchange of gases is crucial for the survival of both plants and animals on our planet.

Is the stratosphere hot or cold?

The stratosphere is typically cold. Temperatures generally decrease with altitude in the stratosphere due to the low concentration of water vapor and presence of ozone, which absorbs and retains heat.

Enumerate and describe the 5 layers of atmosphere?

The 5 layers of the atmosphere are the Troposphere, Stratosphere, Mesosphere, Thermosphere, and the Exosphere. Troposphere is closest to earth...its also where we live,stratosphere is where our equator is located, mesosphere is the coldest of them all, thermosphere is the hottest, and then the exosphere is farthest from the earth.

Explain why earth's atmosphere is mainly heated from the ground up?

Earth's atmosphere is mainly heated from the ground up because the heat is absorbed into the ground. The warmed surface of the earth then emits heat as infrared radiation which rises into the atmosphere. There the greenhouse gases like water vapour, carbon dioxide and methane absorb and hold the heat.

What gas comprises nearly 1 percent of Earth's atmosphere?

Argon makes up roughly one percent of Earth's atmospheric gases. A more precise/exact amount would be 0.93%

What percent of the world is covered by rainforests?

Rainforests cover approximately 6-7% of the world's land surface.

What is the second lowest layer in the atmosphere?

The stratosphere is the second lowest layer in the Earth's atmosphere, located above the troposphere. It extends from about 10 to 50 kilometers above the Earth's surface and contains the ozone layer, which absorbs ultraviolet radiation from the sun.

What is the trend in atmospheric CO2 seasonally and over the past 50 years?

Atmospheric CO2 levels have been rising steadily over the past 50 years due to human activities such as burning fossil fuels and deforestation. Seasonal fluctuations occur due to natural processes like plant growth absorbing CO2 in the spring and summer, and releasing it back in the fall and winter. However, the overall trend shows a significant increase in atmospheric CO2 concentration.

What happens to solar energy as it enters the atmosphere?

About half of it is absorbed, reflected, or scattered within the atmosphere. The remainder reaches the earth, where it heats it. This radiation emitted by the earth heats the lower atmosphere and generates the earth's weather.

A:Some is absorbed to make ozone (UV-C and more energetic), some is absorbed to break ozone back down (UV-B and more energetic). Some is absorbed and radiated back to space (infrared and less energetic) or captured by greenhouse gases. Lots of it is passed down to Earth's surface (UV-A thru the near infrared).

What are the layers that the atmosphere is made up of?

The atmosphere is made up of different layers: the troposphere (closest to Earth's surface), the stratosphere, the mesosphere, the thermosphere, and the exosphere. Each layer has unique characteristics and plays a different role in Earth's atmosphere.

What is the second coldest city on earth?

The second coldest city on earth is Oymyakon, Russia. It holds the record for the lowest temperature ever recorded in a permanently inhabited locality, which was a bone-chilling -67.7°C (-89.9°F) in 1933.

What is the earth's temperature with carbon dioxide?

The presence of carbon dioxide in the atmosphere acts as a greenhouse gas, trapping heat and leading to an increase in the Earth's temperature. This phenomenon is known as global warming and is contributing to climate change by causing shifts in weather patterns and rising sea levels.

Which gas has increase over last 100 years?

Carbon dioxide (CO2) levels have increased significantly over the last 100 years due to human activities such as burning fossil fuels and deforestation. This increase in CO2 is a major contributor to global climate change and the warming of the planet.

How does the atmosphere in In His Steps begin and How does it end?

The atmosphere in the beginning is a fog of deception as the evil spirits cloud the judgement of the faithful. By the end of the book, Lucifer has usurped his power over Raymond because Reverend Maxwell shot flaming arrows at him from his tongue.

Which measurement represents standard atmospheric pressure?

Pascals (1 Pascal = 1Newton/m^2)

1000 Pascals = 1 kiloPascal

Most of weather stations and such will display air pressure in kiloPascals (kPa) unless you're one of them's United States folks, in which case it may be displayed in pounds per square inch (psi). I don't know.

Which planets have a banded layered atmosphere?

Jupiter and Saturn have banded layered atmospheres. These bands are made up of alternating belts of clouds that circulate in opposite directions. The distinctive bands are caused by the planets' rapid rotation and strong atmospheric dynamics.

Did Earth have a thick atmosphere?

Yes, Earth's atmosphere has always been thinner than that of planets like Venus or Mars. Earth's atmosphere consists mainly of nitrogen and oxygen, with trace amounts of other gases. The ancient Earth had a different composition of gases in its atmosphere compared to today, but it was never as thick as Venus or as thin as Mars.

How does the atmosphere reflect energy?

The atmosphere reflects incoming solar energy in the form of sunlight. Different components of the atmosphere, such as clouds, dust particles, and gases, can scatter or absorb sunlight, which affects how much energy reaches Earth's surface. This energy exchange plays a key role in regulating Earth's climate and temperature.

Explain the three mechanism of heat transfer in Earth atmosphere?

Green house gas absorbs the radiation that would actually be emitted into space. This raises the earth's temperature. Clouds, absorption through the surface of the earth, earth's magnetic field changes, etc., relate to heat transfer in the earth-atmosphere system.

What is the most abundant compounds in the earth's atmosphere?

The most abundant compounds in Earth's atmosphere are nitrogen gas (N2) and oxygen gas (O2). Nitrogen makes up about 78% of the atmosphere, while oxygen comprises about 21%. Other gases like argon, carbon dioxide, and water vapor are present in much smaller amounts.
