Atmospheric Sciences

You don't feel the weight of the air column because the air pressure inside your body and the air pressure outside your body are equalized. This balance prevents you from feeling the weight of the column of air pressing down on you.

The dancing lights of the ionosphere are known as auroras. In the Northern Hemisphere they are called the Aurora Borealis or Northern Lights. In the Southern Hemisphere they are known as the Aurora Australialis or Southern Lights.

1. It contains high-energy particles and high-speed molecules like hydrogen and helium.
2. The International Space Station orbits within the Exosphere.
3. It has a very low density and extends from about 500 km to 10,000 km above Earth's surface.

1. As altitude increases, air pressure decreases due to lower density of air molecules at higher altitudes.
2. The temperature typically decreases with altitude as the atmosphere becomes thinner and can't retain heat as effectively.
3. Humidity levels may fluctuate, but generally moisture content decreases with altitude, leading to drier conditions.

The percentage of oxygen in the atmosphere is approximately 21%. Nitrogen makes up 78% and the last 2% percent is a mixture of various different gases, mostly argon.

The layer of the atmosphere that merges into outer space is the exosphere. This is the outermost layer of the Earth's atmosphere where the air is very thin and gradually blends into the vacuum of space.

The ozone layer protects us from the sun's powerful rays.

The Ozone layer protects us from the ultra violet rays from the sunlight which can cause skin cancers and eye cataracts, as well as damaging crops like rice and wheat.

There are 101,325 pascals in 1 atmosphere.

The outer layer of the thermosphere is known as the exosphere. It is the outermost layer of Earth's atmosphere and gradually transitions into outer space. The exosphere is characterized by extremely low densities of gas molecules and the presence of free-moving particles.

The ionosphere contains ionized particles, such as ions and free electrons, that are created by the sun's radiation. It plays a critical role in radio wave propagation and reflects radio waves back to the ground, enabling long-distance communication. The ionosphere's density and composition can vary based on factors like solar activity and time of day.

No, the atmosphere is constantly changing due to processes like evaporation, condensation, and air movement. Factors like weather patterns, human activities, and natural events can also influence the composition and behavior of the atmosphere.

No, the atmosphere is not always the same. It can vary in composition and characteristics due to factors like weather patterns, human activities, and natural events like volcanic eruptions. These variations can impact things like air quality, temperature, and precipitation patterns.

The mesosphere contains mainly gases like oxygen, nitrogen, and carbon dioxide. It also includes small amounts of water vapor, dust particles, and meteoric debris. Temperature decreases with altitude in the mesosphere, reaching as low as -90°C.

In a word -- everywhere.

If the distance from you to any other mass in the universe is less than infinite,
then there is a gravitational force between you and something else, drawing
the two of you toward each other.

Greenhouse gases such as carbon dioxide (CO2), methane (CH4), and water vapor trap the sun's warmth in the Earth's atmosphere, leading to the greenhouse effect. These gases absorb infrared radiation emitted by the Earth's surface and re-radiate it back, helping to keep the planet warm.

Tornadoes are twisting spirals of air that can cause widespread destruction by flinging debris, knocking down buildings, and uprooting trees. They form from powerful thunderstorms and can have wind speeds exceeding 200 mph, making them incredibly dangerous natural phenomena.

Cosmos, in astronomy, the entire physical universe considered as a unified whole (from the Greek kosmos, meaning “order,” “harmony,” and “the world”).

Generally speaking, we use the word universe to mean the entire physical universe; a synonym is cosmos.

Typically 660-670 mmHg (88-90 kPa).

Actually the Barometric pressure changes frequently during different periods of the year and in the winter months around January its about 101-102 KPA.

Gases like helium can escape Earth's atmosphere because they have low molecular weight, which allows them to reach escape velocity more easily. Additionally, helium is light enough to be carried away by solar winds, contributing to its escape from the atmosphere.

The 'F region' of the ionosphere is also known as the Appleton layer, named after British physicist Edward Victor Appleton who first proposed its existence in the 1920s. It is the region of the ionosphere that is most ionized and is responsible for reflecting high frequency radio waves.

The Coriolis effect is responsible for causing prevailing winds to blow diagonally instead of strictly north-south or east-west. This effect occurs due to the Earth's rotation, which deflects the winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, leading to a diagonal flow.

Another name for the entire physical universe is cosmos. It is considered the universe as a unified whole in itself.

No, the aurora borealis occurs in the Northern Hemisphere, primarily in high-latitude regions near the Arctic Circle. In the Southern Hemisphere, a similar phenomenon known as the aurora australis occurs near the Antarctic Circle in Antarctica.
