Why do clouds turn GREY?
However, rain clouds are gray instead of white because of their thickness, or height.
That is, a cloud gets thicker and denser as it gathers more water droplets and ice crystals — the thicker it gets, the more light it scatters, resulting in less light penetrating all the way through it..
What are the 4 types of fog?
There are several different types of fog, including radiation fog, advection fog, valley fog, and freezing fog. Radiation fog forms in the evening when heat absorbed by the Earth’s surface during the day is radiated into the air. As heat is transferred from the ground to the air, water droplets form.
What does fog mean in algebra?
fog = f(g(x)) f is the outer function and g is the inner function. … Fog is a term used in functions.. i.e in f(x) if x(domain or input of a function) is replaced by some other function g(x)..then f(g(x)) is called a fog(x).. basically it is a function which is input of some other function.
Is fog just low clouds?
Fog forms only at low altitudes. 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 are the 10 clouds?
Ten Basic CloudsCirrus (Ci), Cirrocumulus (Cc), and Cirrostratus (Cs) are high level clouds. … Altocumulus (Ac), Altostratus (As), and Nimbostratus (Ns) are mid-level clouds They are composed primarily of water droplets. … Cumulus (Cu), Stratocumulus (Sc), Stratus (St), and Cumulonimbus (Cb) are low clouds composed of water droplets.
What is the highest type of cloud?
Cirrus clouds are the highest of all clouds and are composed entirely of ice crystals. Cirrus clouds are precipitating clouds, although the ice crystals evaporate high above the earth’s surface.
Does fog mean it will be sunny?
Fog generally forms under stable conditions and clear skies. It’s a myth that a foggy morning cannot lead to a perfect sunny day. In fact, clear sky is a prerequisite for formation of fog. Clouds generally restrict the outgoing radiation and suppress fog in the lower levels.

How thick can fog get?
Water droplets in the air can reduce visibility enough as it is, but add pollution to the mix and things get much worse. By definition, fog has a visibility of less than 1km, but it can get much thicker than that.
Which is thicker mist or fog?
Fog is much denser than mist and thus has a greater effect on visibility. A person can still see out to about 2 kilometers (1.2 miles) in mist, but a fog will reduce visibility to under one kilometer (0.6 miles).
What kind of cloud is fog?
stratus cloudFog is a form of stratus cloud. Although all fog can creep along on little cat feet, many types of fog exist. The basic mechanism that causes fog is simply anything that can bring the relative humidity up to 100 percent. Usually, when the air cools to the dew point, fog will roll in.
Is fog a stratus cloud?
Stratus clouds may produce a light drizzle or a small amount of snow. These clouds are essentially above-ground fog formed either through the lifting of morning fog or through cold air moving at low altitudes over a region. Some call these clouds “high fog” for their fog-like form.
What is the difference between fog mist and low cloud?
Cloud cover is often referred to as “mist” when encountered on mountains, whereas moisture suspended above a body of water or marsh area is usually called “fog”. One difference between mist and fog is visibility. The phenomenon is called fog if the visibility is 1 km (1,100 yd) or less.
What does FOB mean?
Free On BoardFree On Board (FOB) is a shipment term used to indicate whether the seller or the buyer is liable for goods that are damaged or destroyed during shipping. “FOB shipping point” or “FOB origin” means the buyer is at risk and takes ownership of goods once the seller ships the product.
How is fog formed?
Fog forms when the difference between air temperature and dew point is less than 2.5 °C (4.5 °F). Fog begins to form when water vapor condenses into tiny liquid water droplets that are suspended in the air. … This occurs from either added moisture in the air, or falling ambient air temperature.

How do clouds float?
FLOATING CLOUDS. 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. … So the particles continue to float with the surrounding air.
Why is fog dangerous?
Fog creates dangerous driving conditions and has been the cause of a high number of accidents and fatalities. Fog is a cloud form at the surface of the earth made of tiny water droplets suspended in the air. The greatest problem with fog is visibility. … Slow down and do not drive faster than your vision.
