What condition is required for cloud formation in the atmosphere quizlet?

What to conditions are required for cloud formation

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 2 conditions are required for cloud formation

What two conditions are required for cloud formation? How do clouds form? When water vapor in the air condenses to form liquid water or ice crystals. You just studied 95 terms!

Which of the following is required for cloud formation quizlet

Clouds are formed when the water vapor particles are clustered together to form liquid water. This process is called condensation. b. During condensation, the presence of air particles and the coolness of the air are the conditions that are required in this process.

Which of the following contribute to the formation of clouds quizlet

Conditions necessary for clouds to form. Clouds form when the air is cool and condensation occurs. For water vapor to condense and to form a cloud, a solid surface must be available, like DUST.

What causes the development of most clouds and precipitation in the atmosphere

Rising warm air cools, resulting in cloud formation and rain. Why does rain occur near a warm front? Rising warm air cools, resulting in cloud formation and rain. What causes the development of most clouds and precipitation in the atmosphere?

What are the 5 steps of cloud formation

Terms in this set (5)

• warm air rises and cools.
• the relative humidity of the air increases.
• air eventually becomes saturated.
• water vapor condenses on smoke, dust, salt, and other small particals.
• millions of tiny water drops of liquid water collect to form a cloud.

Why do most clouds form in the troposphere quizlet

We humans live in the troposphere, and nearly all weather occurs in this lowest layer. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. Air pressure drops, and temperatures get colder, as you climb higher in the troposphere.

Why do clouds usually form over areas of low pressure air

When air rises in the atmosphere it gets cooler and is under less pressure. When air cools, it's not able to hold all of the water vapor it once was. Air also can't hold as much water when air pressure drops. The vapor becomes small water droplets or ice crystals and a cloud is formed.

What clouds are formed when air masses rise vertically in the atmosphere

Cumulus clouds are likely to have updrafts and downdrafts that allow it to swell into large clouds. Cumulus clouds are not separated from other clouds, and does not allow the sun to shine through.

Why do clouds usually form high in the air instead of near Earths surface quizlet

Why do clouds usually form high in the air instead of near Earth's surface? Cold air is less dense on the ground so clouds form in the sky were it is cooler.

What clouds form in low flat layers

Stratus clouds are uniform and flat, producing a gray layer of cloud cover which may be precipitation-free or may cause periods of light precipitation or drizzle.

What are the three main classifications of clouds

While clouds appear in infinite shapes and sizes they fall into some basic forms. From his Essay of the Modifications of Clouds (1803) Luke Howard divided clouds into three categories; cirrus, cumulus and stratus. The Latin word 'cirro' means curl of hair.

What happens to rising air quizlet

* the rising air remains warmer than surrounding air, and rises where vapor condenses and forms the billowing columns. occurs when Earth's surface and air near the surface cool by radiation during the night.

When water vapor is warmer and less dense than the surrounding air it rises

If the air is warmer (less dense) than the surrounding air, then it is called unstable air. Unstable air will rise (much like a hot-air balloon). are high (6,000-15,000 m), wispy clouds composed of ice crystals rather than water droplets.

Which two conditions are required for cloud formation quizlet

What two conditions are required for cloud formation? How do clouds form? When water vapor in the air condenses to form liquid water or ice crystals. You just studied 95 terms!

Which of the following conditions affect the formation of clouds

For instance, temperature, humidity and altitude are all factors that affect cloud formation. But how do clouds move and eventually disappear? The difference between air within a cloud and the air surrounding it dictates cloud movement.

What are the four processes of cooling that can lead to cloud formation

– Most clouds form when air cools to the dew point as a parcel of air rises vertically. – There are four lifting mechanisms that form clouds: Orographic Lifting, Convection, Convergence, and Updraft.

What conditions must occur for water Vapour in clouds to fall as precipitation

Water droplets may grow as a result of additional condensation of water vapor when the particles collide. If enough collisions occur to produce a droplet with a fall velocity which exceeds the cloud updraft speed, then it will fall out of the cloud as precipitation.
