What if the clouds fell?
No, really: imagine if Earth’s atmosphere collapsed.
All the oxygen, nitrogen and other stuff in Earth’s atmosphere has a whopping combined mass of 5 quadrillion tons, so a falling sky would mean that nearly 10 tons of molecules — roughly the heft of a school bus — would drop on every square meter of Earth’s surface..
Why are clouds white?
As light moves through the clouds, it is dispersed by water droplets. These are comparable to or bigger than the wavelengths of light, Dr. … “Looking at a cloud from any other angle, you see a mixture of all the scattered colors, so it looks white,” Dr. Kaufman said.
What is the biggest cloud?
Noctilucent cloudsNoctilucent clouds are the highest clouds in the sky, however they are not associated with weather like the rest of the clouds in this table.
Is fog a cloud?
Clouds can form at many different altitudes. They can be as high as 12 miles above sea level or as low as the ground. Fog is a kind of cloud that touches the ground. Fog forms when the air near the ground cools enough to turn its water vapor into liquid water or ice.
What does Clouds feel like?
If you’ve ever been outside on a foggy day, you’ve essentially been inside a cloud, just one very close to the ground instead of high in the sky. Fog and clouds are both made of tiny water droplets – like the ones you can sometimes see or feel in a hot, steamy shower. Clouds form through evaporation and condensation.
What keeps clouds from falling?
Even though dust is heavier than the air around it, a dust particle is so small that it can float in the air for a long time before falling. … The second reason that clouds can float in the air is that there is a constant flow of warm air rising to meet the cloud: the warm air pushes up on the cloud and keeps it afloat.
Do clouds smell?
Lightning inside of clouds produces ozone—that’s the smell that tells you that a storm is on the way. Ozone is made up of three oxygen atoms, and has sort of a light chlorine smell, says Dalton. Some people might describe it as fresh, others as a little sharp.
What happens if you touch a rainbow?
In short, you can touch someone else’s rainbow, but not your own. A rainbow is light reflecting and refracting off water particles in the air, such as rain or mist. The water particles and refracted light that form the rainbow you see can be miles away and are too distant to touch.
Why are clouds important to humans?
And yet, clouds have an enormous influence on Earth’s energy balance, climate, and weather. Clouds are the key regulator of the planet’s average tem- perature. Some clouds contribute to cooling because they reflect some of the Sun’s energy—called solar energy or shortwave radiation—back to space.
Why do clouds stay together?
If the surrounding air has a low humidity, the water droplets or ice crystals that make up the cloud quickly evaporate as the cloudy air mixes with its surroundings; this results in the cloud maintaining a sharp boundary.
Why do the clouds seem floating in the sky?
The water and ice particles in the clouds we see are simply too small to feel the effects of gravity. As a result, clouds appear to float on air. Clouds are composed primarily of small water droplets and, if it’s cold enough, ice crystals.
Are clouds hot or cold?
Clouds consist of microscopic droplets of liquid water (warm clouds), tiny crystals of ice (cold clouds), or both (mixed phase clouds). Cloud droplets initially form by the condensation of water vapor onto condensation nuclei when the supersaturation of air exceeds a critical value according to Köhler theory.
Why clouds are not falling down?
Water is not lighter than air – water does not float. So why don’t clouds fall out of the sky? The two biggest reasons that clouds stay in the sky are 1) small drops, and 2) wind. … Because small drops have less mass and more surface area than large drops, they have a harder time pushing the air out of the way.
Why do clouds turn pink?
Red, orange and pink clouds occur almost entirely at sunrise and sunset and are the result of the scattering of sunlight by the atmosphere. … The clouds do not become that color; they are reflecting long and unscattered rays of sunlight, which are predominant at those hours.
What FOG stands for?
FOG. Fiber-Optic Gyro. FOG. Fear, Obligation & Guilt (psychology)
What is a the cloud?
The definition for the cloud can seem murky, but essentially, it’s a term used to describe a global network of servers, each with a unique function. The cloud is not a physical entity, but instead is a vast network of remote servers around the globe which are linked together and meant to operate as a single ecosystem.
How are clouds in the sky?
Clouds form from water in the sky. The water may evaporate from the ground or move from other areas. Water vapor is always in the sky in some amount but is invisible. Clouds form when an area of air becomes cooler until the water vapor there condenses to liquid form.
