Atmospheric Sciences

Humans began adding significant amounts of greenhouse gases to the atmosphere during the Industrial Revolution in the mid-18th century. This period marked the widespread use of fossil fuels such as coal, oil, and gas, leading to a rapid increase in carbon dioxide emissions.

Without neon in our atmosphere, the color of neon lights would not exist as we know them today. Neon is used in neon lights to produce the distinct bright colors. Additionally, neon is chemically inert, so its absence wouldn't have a significant impact on atmospheric chemistry or human health.

You would not feel warm in the thermosphere because even though temperatures in the thermosphere can reach thousands of degrees Celsius, the air density is extremely low. This means that there are very few air molecules to transfer heat to your body, so you would not feel hot.

The core of the Sun is the layer that contains the densest material. It is where nuclear fusion reactions occur, resulting in high temperatures and pressures, which contribute to the density of the core.

The gas you are referring to might be ozone. The effect caused by ozone in the upper atmosphere is the formation of the ozone layer. This layer protects Earth by absorbing the majority of the sun's harmful ultraviolet radiation.

The troposphere is typically colder as you go higher in altitude. On average, the temperature decreases by about 6.5°C for every kilometer increase in altitude within the troposphere.

The aurorae are best visible from the Arctic and Antarctic Circles - and/or locations close to them. It's very rare to see the aurorae near the equator or latitudes as far south(or north) as say, Los Angeles.

The atmosphere gets hot due to the greenhouse effect, which traps heat from the sun. Greenhouse gases like carbon dioxide and methane absorb and re-radiate this heat, causing temperatures to increase. Human activities, such as burning fossil fuels, have contributed to higher levels of greenhouse gases in the atmosphere, intensifying the greenhouse effect and leading to global warming.

The thermosphere starts at an altitude of around 80 kilometers above Earth's surface. It is the layer of the Earth's atmosphere that extends from the mesopause (top of the mesosphere) to the exosphere.

jet stream. It is a narrow band of strong winds that blow from west to east in the upper atmosphere, typically found between 30,000 and 39,000 feet above the Earth's surface. The jet stream plays a crucial role in guiding weather systems and influencing the movement of storms.

Green is the commonest color in the Aurora Borealis as green is produced when charged particles from the sun collide with atoms of oxygen at a high level.

The Aurora over Greenland would sometimes show colors of blue and red, though probably not as often.

True. Scientists believe that Mercury's thin atmosphere is the result of most of its original gases escaping into space due to the planet's low gravity and proximity to the sun.

The atmosphere is a layer of gases that surrounds Earth and is held in place by gravity. It plays a crucial role in regulating temperature, protecting against harmful radiation, and supporting life through processes like photosynthesis. The composition of Earth's atmosphere includes nitrogen, oxygen, and traces of other gases.

The ionosphere is named for its abundance of ions, which are electrically charged particles. In particular, the ionosphere contains ions such as oxygen, nitrogen, and electrons that are responsible for its electrical properties and interaction with solar radiation.

In relative terms cooler air will descend while warmer air will rise. Many times mountains form the border between two differing airmasses. This can be seen

at the front range of the rocky mountains. Cooler air from Canada will be on the west side of the range while warmer air from the gulf of Mexico will be on the east side. When these two air masses meet, the cooler Canadian air will descend down the front range of the mountains beneath the warmer air.

The temperature typically decreases as you move farther away from the equator. This is because areas closer to the poles receive less direct sunlight, leading to cooler temperatures.

This Answer is as Variable, considering all of the varying Parameters, as it is Crucial to Our Tenuous Situation. This percentage, as Critical as it is, in not predictable as the Output of Solar radiation is as unknowable as the powerful Incidence of detrimental Cosmic Rays.

No. The greenhouse effect is the process by which certain gasses, called greenhouse gasses, help to trap heat within Earth's atmosphere. This effect has been in place for as long as Earth has had an atmosphere and is necessary for life to exist. Without it, the planet would freeze over.

Global warming is primarily the result of an enhanced greenhouse effect, caused by extra geenhouse gasses entering the atmosphere.

The dew point is the temperature at which water will condense out of the

air. If the dew point were above the temperature, that would mean that some

of the water vapor in the air should have already condensed out. In such a

situation, the excess water WOULD condense out, lowering the amount of water

vapor and consequently the dew point.

An ice block mixed with rocks is commonly referred to as a glacier. Glaciers form when compacted snow turns into ice over time, and they can incorporate rocks and debris as they move and erode the landscape.

The percentage of oxygen in air remains fairly constant on a global scale but varies considerably on a local scale. The concentration of oxygen in your lungs is much different as you inhale than when you exhale for example. The concentration of oxygen entering your car's engine is much different than the concentration in the exhaust from that same engine.

The percentage remains fairly constant on a macroscopic scale because of the equilibrium established by the uptake by plants of the carbon dioxide and subsequent release of oxygen through photosynthesis. There is also a substantial amount of oxygen dissolved into the oceans of the Earth which remains in equilibrium with the oxygen in the air. Just based on the scale, it would take an enormous amount of oxygen addition or removal from the atmosphere to make a significant change in the percentage of oxygen in the atmosphere. Such a change would take a very long time to accomplish. In truth, the composition of the atmosphere millions of years ago was different than now - with noticeably higher levels at times and lower levels at other times. It took millions of years for the changes to occur however.

An anemometer measures wind speed. It usually consists of a set of cups that rotate in the wind, and the speed of rotation is used to determine the wind speed.

The mesosphere primarily consists of neutral gases such as molecular nitrogen (N2) and molecular oxygen (O2). Other minor components include trace amounts of water vapor, carbon dioxide, and ozone. The density of these gases decreases with increasing altitude in the mesosphere.

Short term conditions in the atmosphere refer to weather phenomena like temperature, precipitation, humidity, and wind that can change quickly and are typically observed over hours to days. These conditions play a significant role in daily weather patterns and impact our daily activities and environments. Tracking these short-term conditions is essential for weather forecasting and planning.
