To Be Classified As Rain, Water Droplets That Fall From A Cloud Must Be Of What Minimum Diameter?

Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen the parcel of air must be saturated i.e. unable to hold all the water it contains in vapor form so it starts to condense into a liquid or solid form.

What term describes the process by which water vapor changes to the liquid state?

Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds. … Condensation is the opposite of evaporation.

What would happen if the temperature were cooled to 15 C?

What would happen if the temperature were cooled to 15°C? This process results in the release of about 600 calories of latent heat per gram of water. Relative humidity is usually expressed as a percent. … relative humidity will increase.

Which weather change usually occurs when the difference between the air temperature and the dewpoint temperature is decreasing?

An increasing graph. Which weather change usually occurs when the difference between the air temperature and the dew-point temperature is decreasing? The relative humidity increases.

Which statement best describes the difference in air temperature and humidity between the cP and mT?

Which statement best describes the difference in air temperature and humidity between the cP and mT air masses? The mT air mass is warmer and more humid.

How are clouds are classified?

Scientists classify clouds by how high they are in the sky (low medium or high) and by whether they are flat (stratus) puffy (cumulus) rain-filled (nimbus) or a combination of these characteristics. Saucer-shaped lenticular clouds are common in mountainous regions of the world.

How are clouds formed classify them?

Answer: Clouds are formed by the process of evaporation and condensation. Cooling causes condensation of water vapour which leads to the formation of tiny droplets. Tiny droplets grow bigger and heavy by more condensation which ultimately leads to the formation of clouds.

What are the 3 conditions needed for a cloud to form?

Students will discover that three main ingredients are needed for clouds to form: moisture condensation and temperature.

What is it called when water falls from the atmosphere to the earth?

Precipitation is water released from clouds in the form of rain freezing rain sleet snow or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.

What is process of water cycle?

The water cycle consists of three major processes: evaporation condensation and precipitation. Evaporation is the process of a liquid’s surface changing to a gas. In the water cycle liquid water (in the ocean lakes or rivers) evaporates and becomes water vapor. … Water vapor is also an important greenhouse gas.

What is condensation class 6th?

Condensation is a process of changing of a substance from vapour to liquid on cooling. … So liquid form of water is changing into vapour form.

What would happen if the temperature were cooled to 15 C quizlet?

What would happen if the temperature were cooled to 15°C? temperature increased from 25°C? It would decrease. This fog results from adiabatic cooling.

When air is cooled to its dew point the relative humidity is 100% Group of answer choices?

The dew point is the temperature at which the air is saturated with respect to water vapor over a liquid surface. When the temperature is equal to the dewpoint then the relative humidity is 100%.

How does snow vary with temperature quizlet?

How does snow vary with temperature? Cold snow is powdery and light while warm snow is moist.

Which event usually occurs when air is cooled to its dew point temperature?

Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water. Dew point is the temperature at which condensation happens.

Which weather change is most likely indicated by rapidly falling air pressure?

Rapidly falling air pressure would most likely indicate (4) a storm is approaching.

When the air temperature is closer to the dew point temperature and precipitation is?

The closer the dew point is to the air temperature the closer the air is to saturation. The temperature the dew point temperature and the relative humidity are related to one another.

What determines the temperature and humidity of an air mass?

Air masses are characterized by their temperature and humidity properties. The properties of air masses are determined by the the underlying surface properties where they originate. Once formed air masses migrate within the general circulation.

What is the air temperature shown on the station model?

What are daily weather forecasts based primarily on?

Once calculated manually based mainly upon changes in barometric pressure current weather conditions and sky condition or cloud cover weather forecasting now relies on computer-based models that take many atmospheric factors into account.

How clouds are classified identify types of precipitation?

Almost all rain is produced from low-level clouds. Stratus clouds produce steady rains and cumulus clouds produce intense stormy precipitation. Mid-level clouds can tip you off to the potential for these precipitation-producing cloud types to develop and may even produce an occasional sprinkle themselves.

What are the four different cloud groups and how are they classified?

These types are Cirrus (meaning hair like) Stratus (meaning layer) Cumulus (meaning pile) and Nimbus (meaning rain producing). Each main classification may be further subdivided to provide a means of identifying the many variations which are observed in the atmosphere.

What do clouds made of water droplets look like?
