Which type of air can hold more water vapor

The amount of water vapor that is within the air is called what?

The amount of water vapor within the atmosphere compared to the amount of water vapor needed to saturate the air at a certain temperature.

This device is used to add water vapor into the air.

This device is used to remove water vapor from the air.

The temperature at which the saturation of air occurs and condensation forms is called what?

What type of formation forms clouds when the sun heats Earth’s surface causing moist air to warm up, rise and turn into water vapor and then a cloud.

What type of formation forms clouds when winds blow together forcing warmer, moist air upwards creating a cloud.

What type of formation forms clouds when moist air is blown upward do to higher elevations of mountains it is forced to cool because of the lower temperature of the troposphere.

What type of formation forms clouds when cold air weather systems come in contact with warm air weather systems and the warm, moist air is forced upwards as it is less dense forming clouds

Which of the following is not a shape of cloud?

These clouds are usually large gray low laying masses that can look like fog.

These clouds are masses of puffy,

white or light gray colored clouds that

look like floating cotton balls.

These clouds look like long, thin,

feather-like clouds high in the sky and are

composed of ice crystals.

These are transparent, thin, sheet-like clouds that cover most or all of the sky at high altitudes.

These clouds are smaller puffy looking shapes that can be found at high altitudes and are made of ice crystals.

These clouds can be found at all altitude levels.

These clouds are man made formed from airplane exhaust.

These clouds can be darker in color and indicate the presence of precipitation about to be released.

What type of clouds are shown in the image?

This type of precipitation forms when a thicker wedge of warm air is above cold air at the ground, allowing a raindrop to survive until it comes in contact with the cold ground

This type of precipitation forms when snowflakes melt into a raindrop in a wedge of warm air well above the ground and then refreeze in a layer of freezing air just above the surface.

This type of precipitation forms when frozen water droplets that form within cumulonimbus clouds when water freezes in layers around a small piece of ice.

This type of precipitation forms in a process known as accretion, ice crystals form instantly on the outside of the snowflake and accumulate until the original snowflake is no longer visible or distinguishable.

A large body of air that has properties similar to the area of Earth’s surface that it develops over.

Warm and moist air masses are called what type of air mass?

Cool and moist air masses are called what type of air mass?

Warm and dry air masses are called what type of air mass?

What is the system called in areas of high pressure where winds blow away from the center of system.

What is the system called in areas of low pressure where winds blow towards the center of system.

A boundary between two air masses of different pressures, moisture levels, and temperatures is called what

Which type of front is shown in the image?

Which type of front is shown in the image?

Which type of front is shown in the image?

Which type of front occurs when cold air is wedged underneath the warm air forcing warm air to rise up. When the temperature difference between the systems is large, thunderstorms may result.

Which type of front occurs when lighter, warm air advances over cold, heavy air as both are travelling in the same direction. These fronts tend to bring warmer, fair weather, and gentle precipitation instead of storms.

Which type of front occurs when three air masses of different temperatures of cold air, warm air, and cool air bringing large periods of precipitation, wind, and cool temperatures?

These fronts may remain in the same place for days at a time bringing cloudy and possibly rainy weather that remains constant for extended periods of time?

These fronts are labelled on a weather map as a line with red semi-circles.

These fronts are labelled on a weather map as a line with blue semi-circles

These fronts are drawn on a weather map as an alternating red and blue line with blue triangles pointing towards the warm air and red semicircles pointing towards the cold air.

These fronts are drawn on a weather map as a purple line with semicircles and triangles.
