What is condensation necessary for clouds to form?

What is condensation necessary for clouds to form?

Three things are necessary for clouds in the atmosphere to form: Moisture – There must be sufficient water vapor in the air for a cloud to form. Cooling air – The air temperature must decrease enough for water vapor to condense. This also causes the air to heat up as molecules collide with each other more often.

Why is condensation necessary for clouds for kids?

Condensation is a part of the water cycle and is an essential part of cloud formation. The rapidly cooling air couldn’t hold as much water as warm air, and the vapor reverted to its liquid form. In the atmosphere, warm air cools as it rises, and water vapor condenses around tiny pieces of matter.

Why are condensation nuclei needed for clouds to form?

The formation of clouds, fog, or haze requires the assistance of condensation nuclei. Condensation nuclei provide the non-gaseous surface necessary for water vapor to condense into cloud droplets. As droplets join together they grow larger and eventually fall as precipitation.

Why is water necessary for cloud formation?

Through the process of evaporation and transpiration, water moves into the atmosphere. As the water vapor rises it cools due to a decrease in pressure. When it cools enough, the water vapor then condenses as liquid water on dust particles to create clouds.

What is condensation explain briefly the process of condensation?

Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. 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.

How does the process of condensation help in the formation of clouds?

Fog develops when air having a relatively high humidity comes in contact with a colder surface, often the Earth’s surface, and cools to the dew point. Additional cooling leads to condensation and the growth of low-level clouds. Fog that develops when warmer air moves over a colder surface is known as advective fog.

What is cloud condensation?

Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.

What is the importance of condensation nuclei quizlet?

Cloud condensation nuclei promote condensation of water vapor at temperatures above and below the freezing point of water. These nuclei provide surfaces on which water vapor can condense or deposit.

How and why clouds are formed?

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.

Why does condensation happen?

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. When warm air hits the cold surface, it reaches its dew point and condenses.

What is the basic reason why condensation is not very important in causing a cloud droplet to grow to raindrop size?

What is the basic reason why condensation is not very important in causing a cloud droplet to grow to raindrop size? There are too many droplets competing for the available water vapor. A cloud that forms liquid droplets has a relative humidity of 100 percent with respect to the liquid droplets.
