Atmospheric Sciences

The atmosphere protects living things from a lot of things. Some of these include keeping temperatures from being too hot or cold, being burned severely by the sun, and keeping oxygen in so that we can breathe.

Upper atmosphere winds are high-altitude horizontal air movements that occur above the Earth's surface, typically in the stratosphere and mesosphere. These winds are influenced by factors such as the Earth's rotation, temperature gradients, and pressure differences, and play a crucial role in weather patterns and global circulation. For example, the polar jet stream and the subtropical jet stream are two well-known upper atmosphere wind patterns that can impact weather systems on Earth.

The northern lights - the Aurora Borealis - it is only visible in the sky from the Northern Hemisphere, the chance of visibility increasing with proximity to the north magnetic pole, it most often occurs from September to October and from March to April. I presume the questioner meant when did it last appear at a particular location. But this cannot be answered without knowing the location.

the exosphere is a layer in space and generally is not taken as one of the atmospheric layers whereas the ionosphere is a layer containing highly charged anions and is an upper part of the thermosphere.

From the surface of the sun to its center, temperatures can be assumed to increase. The surface temperature of the sun is around 5500 degrees Celsius, while the core temperature is estimated to be around 15 million degrees Celsius.

Auroras can usually be observed in regions near the Earth's poles, such as the Arctic and Antarctic regions. They are most commonly seen in areas within the Auroral Oval, which encompasses parts of Canada, Alaska, Scandinavia, and Russia. The frequency and visibility of auroras depend on various factors like solar activity and atmospheric conditions.

The coldest month in Brazil is typically July, which is during the winter season in the Southern Hemisphere. Temperatures can vary depending on the region, with temperatures being coldest in the southernmost parts of the country, such as in cities like Curitiba and Porto Alegre.

The Sun's atmosphere is primarily composed of hydrogen and helium. These two gases make up over 98% of the Sun's total mass. Other gases present in smaller amounts include oxygen, carbon, neon, and iron.

Because the sun (Sol) has them all trapped in its gravitational field. All the planets revolve around the sun and so all the planet's satellites revolve around the sun, too.

There are quite a few more objects that are part of Sol's gravitational field- comets, asteroids etc.

From space, land appears predominantly green because it is covered with vegetation like forests, grasslands, and crops that collectively create a green hue. However, from Earth, we see land in various colors based on the type of terrain, soil, and land use. The color contrast is more evident at ground level due to different features like deserts, mountains, water bodies, and man-made structures.

Contour lines represent elevation on a topographic map. Lines close together indicate steep slopes, while lines far apart indicate gentle slopes. Contour lines that form concentric loops indicate hills or depressions, showing a relief in the area.

The Aurora Borealis are the "northern lights", caused by electrically charged particles launched from the Sun and interacting with the Earth's magnetic field. It's sort of like an enormous neon light high in the tenuous atmosphere.

The Aurora Australis are the southern lights, which are essentially similar. But because fewer people live in chilly southern latitudes as opposed to northern ones, they are not as well known.

The ionosphere is a region of Earth's atmosphere that starts at about 30 miles above the surface and extends upward to about 600 miles. It plays a crucial role in propagating long-distance radio communications by reflecting radio waves back to Earth. It also helps protect the Earth from solar radiation by absorbing and dispersing some of the energy.

oxygen!!!!!! phytoplankton produces about 80% of the worlds oxygen! if they die we die!of course trees will back us up but there is not enough trees for the whole world to share oxygen. if the phytoplankton die, with trees, our death will slowly take effect! in days we will all be taking in shorter breaths and eventually die!

Aircraft have red and GREEN wingtip lights, not red and blue. (And you cannot see both the red and green lights together, unless it is heading straight toward you.) Aircraft also have white strobe lights on the belly.

Is it moving against the background of the stars? High in the sky, or down low near the horizon? How fast was it blinking?

No, meteors are not extinct. Meteors are commonly seen in the Earth's atmosphere as shooting stars when they burn up upon entry. They are remnants of debris from space that enter the Earth's atmosphere.

The term "ozonosphere" is not commonly used in atmospheric science. It may be confused with the term "ozone layer," which refers to a region of the Earth's stratosphere that contains a high concentration of ozone gas. This ozone layer plays a crucial role in absorbing ultraviolet radiation from the sun, protecting life on Earth.

I don't have real-time data, but the moon's appearance changes throughout the lunar cycle. You can check a lunar calendar or moon phase app for specific details on what the moon has looked like in the past week.

Lighting typically comes from the sky during daytime, as sunlight is the source of light on Earth. However, artificial lighting and reflections can also create the appearance of light coming from the ground.

The earth's outer core, composed of molten iron and nickel, acts like a giant magnet, generating the planet's magnetic field through a process known as the geodynamo effect. This magnetic field plays a crucial role in protecting Earth from the solar wind and cosmic radiation.

The atmosphere provides oxygen for breathing, acts as a protective shield by absorbing harmful solar radiation, and regulates the Earth's temperature to create a habitable environment for living organisms.

The ionosphere is composed mostly of atomic oxygen, molecular oxygen, and nitrogen gases. These gases become ionized by solar radiation, creating charged particles that affect radio wave propagation and other communication signals in the Earth's atmosphere.

The atmosphere is the sphere of the Earth that encompasses air and weather. It is composed of different layers that extend from the Earth's surface into space and plays a crucial role in influencing climate and weather patterns.

The coldest thing known to man is most surprisingly something man made... liquid hydrogen.It is cooled to -423.17 F./-252.87 C. It has 99.79% parahydogen and .21% orthohydrogen... so thats the answer. thx..,,/][][{{

Nitrogen in the air comes from two main sources: volcanic activity and biological processes. Volcanic eruptions release nitrogen into the atmosphere, while living organisms and certain bacteria convert nitrogen from the soil into a form that can be used by plants, which then release it back into the air through processes like respiration and decay.
