Clouds

A cloud is a visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes up to several miles above sea level. They are generally produced by the condensation of water vapor. Other clouds, less commonly seen, are composed of smokes or dusts.

Describe hail and explain why it doesn't fall during every thunder storm?

Hail starts as rain. It is held in upflowing air long enough to cool, freeze, accumulate more water which cools and freezes, until it is too heavy to hold up any longer. Not all storms have upflowing air, or the altitude necessary to reach the really cold places.

When are clouds formed by ice crystal instead of drops of liquid water?

Clouds form with ice crystals instead of liquid water droplets when the temperature is below freezing in the atmosphere. Ice crystals can also form in clouds that are very high up in the atmosphere where temperatures are colder.

What is the temperature at which air can no longer hold all the water vapor?

That's an approximate definition of saturation. And the temperature at which the current amount of water vapor in the air would be the saturation point is called the dew point. The dew point is a measure of absolute humidity.


Why lenticular cloud won't appear?

I always asking my mom why lenticular cloud won't appear Can everyone post a comment about lenticular cloud plz... I want to see a Lenticular cloud I always look up the sky really carefully what clouds up in the sky Plz post me a comment

What causes condensation of water vapor?

The particles of water vapor collect around dust in the air. When they collect, they form droplets of liquid water. In the case of boiling water the steam particles collide with one and other and form droplets large enough to fall down or a decrease in atmospheric pressure and temperature will cause water to form on cooler surfaces

How does wind start a wave?

Wind interacts with the surface of the ocean, creating friction that transfers energy into the water. This energy causes ripples to form, which then develop into waves as the wind continues to blow. The longer and stronger the wind blows, the larger and more powerful the waves become.

What is the rise of an air mass caused by warming over land or sea that often causes the formation of clouds?

This is called convection. As the air near the surface warms, it becomes less dense and starts to rise. This rising warm air can lead to the formation of clouds and potentially result in precipitation.

What is a local storm with tall clouds and heavy rains and thunder with lightning?

This sounds like a description of a thunderstorm. Thunderstorms are characterized by tall cumulonimbus clouds, heavy rainfall, thunder, and lightning. They can produce strong winds, hail, and occasionally tornadoes.

How do you determine north east south and west when traveling?

You can determine the cardinal directions by using a compass, the position of the sun (sunrise is in the east and sets in the west), landmarks (like mountains or rivers), or by using technology like GPS or a mapping app on your phone. Remember that north is towards the North Pole, south is towards the South Pole, east is to the right of north, and west is to the left of north.

Is the heat capacity of dry soil more than water?

Heat capacity of dry soil (0.8 kJ/Kg K) is less than water (4.2 kJ/Kg K) by a factor of about 5. That is water will require 5 times more heat to warm by 1 degree Kelvin (one degree Kelvin = 1 degree Celsius) then the same weight of dry soil.

Steam changing to liquid water is an example of?

Steam changing to liquid water is an example of condensation, which is the process of a gas turning into a liquid. This occurs when the temperature of the gas decreases to the point where it can no longer maintain its gaseous state and transforms into a liquid.

What kind of cloud touches the ground?

A fog cloud is a type of cloud that touches the ground. Fog is formed when moist air near the ground cools down to the point where it can no longer hold all of its moisture, leading to condensation and the formation of fog.

Why can't a jet stream cause a tornado?

The jet stream produces wind shear, or differences in wind speed and direction with changing height. Wind shear is a necessary ingredient for producing tornadoes, but on its own it can't do much.

To get tornadoes you need thunderstorms. When thunderstorms develop in strong enough wind shear they can start to rotate. This rotation can the develop into a tornado. But this sort of rotation cannot be produced by wind shear alone.

What is in common between nimbostratus and cumulonimbus clouds?

Both nimbostratus and cumulonimbus clouds are associated with precipitation. Nimbostratus clouds typically produce continuous light to moderate rain or snow, while cumulonimbus clouds are associated with heavy showers, thunderstorms, and even severe weather events like tornadoes.

What kind of precipitation forms when strong winds toss ice crystals up and down in a cloud?

When strong winds toss ice crystals up and down in a cloud, it can lead to the formation of hail. As the ice crystals are carried up and down in the cloud, they encounter different temperature zones that cause them to grow larger. Eventually, the ice crystals become too heavy to be supported by the wind and fall to the ground as hail.

What is the altitude where cumulus clouds form in km?

Cumulus clouds typically form at altitudes between 1 to 6 kilometers (0.6 to 4 miles) above the Earth's surface.

What is the term for the amount of water in the atmosphere?

The term for the amount of water in the atmosphere is humidity. Humidity is typically measured as either relative humidity, which is the percentage of water vapor present in the air compared to the maximum amount the air can hold at a specific temperature, or absolute humidity, which is the actual amount of water vapor present in the air.

Do clouds melt?

No, clouds do not melt. Clouds are made up of tiny water droplets or ice crystals suspended in the atmosphere. When conditions change, such as rising temperatures or wind patterns, the water droplets may evaporate or fall as precipitation.

Mixture of air and water droplets?

The mixture of air and water droplets is known as fog. Fog forms when water vapor condenses into tiny water droplets in the air, creating a thick mist that obscures visibility. Fog is common in certain weather conditions, such as cool temperatures or high humidity levels.

Where does air and water vapor cross the epidermis at?

Air and water vapor enter and exit through the stomata, tiny pores found on the surface of leaves, stems, and other plant organs. These openings are surrounded by specialized cells that can open and close to regulate gas exchange and water loss.

The destructive power of a tornado is due to what?

The destructive power of a tornado is primarily due to its strong winds, which can reach speeds of over 300 mph. Tornadoes can also cause damage through their ability to pick up and hurl debris at high speeds. Additionally, the intense low pressure inside a tornado can lead to structural damage to buildings and infrastructure.

What does water vapor become when it evaporates?

when water evaporates it condenses and becomes water vapor:)

The Oort Cloud is believed to be?

The Oort Cloud is believed to be a vast spherical region of icy debris extending far beyond the orbits of Neptune and Pluto. It is thought to be the source of long-period comets that occasionally enter the inner solar system.

What is clear sky?

A clear sky refers to a sky without any visible clouds or significant obscuration, resulting in a bright blue appearance during the day and a dark, star-filled sky at night. Clear skies are often associated with good weather conditions and allow for better visibility of celestial objects such as stars and planets.
