What happens when two air masses meet quizlet?
What happens when two air masses meet? When two air masses meet, they form a front, which is a boundary that separates two air masses of different properties. How is a warm front produced? A warm front forms when warm air moves into an area formerly covered by cooler air.
When two air masses collide The formation is called a?
Convergence: When two air masses of the same temperature collide and neither is willing to go back down, the only way to go is up. As the name implies, the two winds converge and rise together in an updraft that often leads to cloud formation.
When two air masses of different temperatures meet they form a boundary called a?
A front is a boundary between two air masses of different densities. A front is a weather system that is the boundary separating two different types of air. One type of air is usually denser than the other, with different temperatures and different levels of humidity.
What might happen when two air masses come together and form a warm front?
As the warm front approaches, there may be fog or increasing rainfall, and thunderstorms may form, as well. This is due to the (usually) higher humidity in the air of warm fronts compared to that of cold fronts.
How do winds form?
During the day, air above the land heats up faster than air over water. Warm air over land expands and rises, and heavier, cooler air rushes in to take its place, creating wind. At night, the winds are reversed because air cools more rapidly over land than it does over water.
What happens when two unlike air masses meet?
This means that when two different bodies of air come together, they do not readily mix. Rather, each body of air will retain its individual properties, and a boundary forms between them. When two large air masses meet, the boundary that separates them is called a front.
What forms when two air masses collide and the fronts become distorted?
As air masses collide the boundary between the fronts sometimes becomes distorted by surface features such as mountains or winds. When this happens bends can happen along the front and the air begins to swirl. What are cyclones? They are a swirling center of low air pressure.
What happens when two weather fronts meet?
Because cold fronts move faster, the cold front is likely to overtake the warm front. This is known as an occluded front. At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. The warm air rises as these air masses come together.
What is it called when a warm and cold fronts meet?
An occluded front forms when a cold front reaches a warm front, forcing all the warm air to rise to higher altitudes and the cold air is stratified near the ground.
How do fronts form?
A warm air mass pushes into a colder air mass (the warm front), and then another cold air mass pushes into the warm air mass (the cold front). Because cold fronts move faster, the cold front is likely to overtake the warm front.
What happens when air masses of different temperatures meet quizlet?
When air masses come together, warm air rises over cold air. The boundary between warm air and cold air is much steeper in a warm front than in a cold front. In a warm front, warm air pushes underneath cold air.
How are tornadoes formed?
Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms. The warm air rises through the colder air, causing an updraft. The updraft will begin to rotate if winds vary sharply in speed or direction.
How is wind formed short answer?
Wind is air in motion. Wind forms when the sun heats one part of the atmosphere differently than another part. This causes expansion of warmer air, making less pressure where it is warm than where it is cooler. Air always moves from high pressure to lower pressure, and this movement of air is wind.
What are two air parcels meet called?
Rather, each body of air will retain its individual properties, and a boundary forms between them. When two large air masses meet, the boundary that separates them is called a front. Fronts represent fairly abrupt transitions between two large air masses.
What happens when cold and warm fronts meet?
An occluded front forms when a cold front reaches a warm front, forcing all the warm air to rise to higher altitudes and the cold air is stratified near the ground.
What type of front is formed when cool air and warm air meet?
This is known as an occluded front. At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. The warm air rises as these air masses come together. Occluded fronts usually form around areas of low atmospheric pressure.
What happens when cold air and hot air meet?

How do warm and cold fronts form?
A warm air mass pushes into a colder air mass (the warm front), and then another cold air mass pushes into the warm air mass (the cold front).
How is a occluded front formed?
An Occluded Front forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward.
What kind of precipitation occurs when air masses of different temperatures meet?
The correct answer is Frontal rainfall. Frontal rainfall occurs when: Two air masses meet one a warm air mass and one a cold air mass. The lighter less dense warm air is forced to rise over the denser cold air.
What is the term used to describe when two air masses of different densities come together?
When two air masses meet together the boundary between the two is called a weather front. At a front the two air masses have different densities based on temperature and do not easily mix. One air mass is lifted above the other creating a low pressure zone. … Fronts are the main cause of stormy weather.

What is a tornado for kids?
A tornado is a lethal combination of wind and power. Tornadoes touch down all over the world, though most often in the United States. A tornado is often a funnel cloud—a rotating column of air— that stretches from a storm to the ground. To be a tornado it must touch the ground.
What is wind class 7?
In simple terms, the wind is nothing but moving air. The air movement is always from high pressure to low-pressure areas.
How are winds named?
A wind is always named according to the direction from which it blows. For example, a wind blowing from west to east is a west wind. The ultimate cause of Earth's winds is solar energy.
What is it called when air masses meet?
When two air masses meet together, the boundary between the two is called a weather front. At a front, the two air masses have different densities, based on temperature, and do not easily mix. One air mass is lifted above the other, creating a low pressure zone.
When two winds meet it is called?
Winds generally blow from high-pressure areas to low-pressure areas. The boundary between these two areas is called a front. The complex relationships between fronts cause different types of wind and weather patterns. Prevailing winds are winds that blow from a single direction over a specific area of the Earth.

What happens when a cold and warm front meet?
Occluded fronts An occluded front forms when a cold front reaches a warm front, forcing all the warm air to rise to higher altitudes and the cold air is stratified near the ground.
