What Are The Two Main Characteristics Of Air Masses?
What two main characteristics are used to classify air masses? Temperature and humidity are two characteristics used to classify air masses.
What are the 2 main characteristics of air masses?
Air masses have fairly uniform temperature and moisture content in horizontal direction (but not uniform in vertical). 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.
What are 2 air characteristics?
- Answer: 1 Air is made up of gases.
- 2 Air has mass.
- 3 Air exerts pressure and has weight.
- 4 Air can be compressed.
- 5 Air is impacted by temperature.
What are three characteristics of air mass?
Continental air masses are characterized by dry air near the surface while maritime air masses are moist. Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot. Arctic air masses are extremely cold.
What are the 4 characteristics of air masses?
There are four categories for air masses: arctic tropical polar and equatorial. Arctic air masses form in the Arctic region and are very cold. Tropical air masses form in low-latitude areas and are moderately warm. Polar air masses take shape in high-latitude regions and are cold.
What characteristics must be different about two air masses in order for them to form a front?
Look for: Sharp temperature changes over a relatively short distance. Change in moisture content. Rapid shifts in wind direction.
What are the main characteristics of air?
- Air takes up space.
- Air has mass.
- Air is affected by heat.
- Air exerts pressure.
- Air can be compressed.
- Air is affected by altitude.
What is the main characteristic of saturated air?
Saturated air is air that holds water vapor at its highest level. Air is composed of moisture or water vapor regardless of the amount of pressure and temperature levels. Adding more moisture to the air at a specific temperature and in an enclosed area causes the air to absorb the moisture.
What are the characteristics of air pollution?
- Plant Life. Sulfur dioxide nitrogen oxide and other air pollutants can enter the pores of developing plants and break down the waxy coating that protects them from disease and excess water loss.

What is air mass and its characteristics?
An air mass is a large mass of air that has similar characteristics of temperature and humidity within it. … When the air mass sits over a region for several days or longer it picks up the distinct temperature and humidity characteristics of that region.
What happens when two air masses meet?
When two different air masses come into contact they don’t mix. They push against each other along a line called a front. When a warm air mass meets a cold air mass the warm air rises since it is lighter. At high altitude it cools and the water vapor it contains condenses.
What are the 6 air masses and their characteristics?
This gives us six total types of air masses on Earth: maritime arctic (mA) maritime polar (mP) maritime tropical (mT) and continental arctic (cA) continental polar (cP) and continental tropical (cT).
What are the 2 characteristics of matter?
It has mass and occupies space. Mass is a physical quantity which expresses the amount of stuff in an object. The space inside the container that is occupied by matter is its volume.
What are the three air fronts and what are characteristics of each?
The type of front depends on both the direction in which the air mass is moving and the characteristics of the air mass. There are four types of fronts that will be described below: cold front warm front stationary front and occluded front.
Where do air masses get their characteristics?
An air mass is a large body of air with generally uniform temperature and humidity. The area over which an air mass originates is what provides its characteristics. The longer the air mass stays over its source region the more likely it will acquire the properties of the surface below.
What 2 air masses create the dry line?
What are the two types of air masses?
- Continental air masses are characterized by dry air near the surface while maritime air masses are moist.
- Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot. Arctic air masses are extremely cold.
When two air masses collide air is forced upward?
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.
What 2 units of air pressure are commonly used in weather reports?
The two most common units in the United States to measure the pressure are “Inches of Mercury” and “Millibars”.
Which is not a characteristic of air?
Air cannot exhibit conduction as it is fluid and conduction is possible only in solids.
What are the two ways in which you can feel the air around you?
You may take a deep breath and feel the air passing through the respiratory system. Motion (move around or move the air with a fan for instance).
What are the characteristics of air and water?
- takes up space.
- there is water in the air.
- moves (wind)
- made of invisible gases.
- people need air to breathe.
- temperature of the air changes the weather (rain snow)
What are the general characteristics of air class 11?
Air is a colourless and odourless gas. It has mass. It exerts some space. It exerts pressure since the weight of air denotes the atmospheric pressure.
What determines the characteristics of a volume of air?
1 – Characteristics of Air
If no force compresses the air it will expand indefinitely to fill the space available. The volume occupied by a given amount of gas varies with the temperature and pressure of the gas. … Air usually has some moisture content.
What are the sources and characteristics of important air pollutants?
There are four main types of air pollution sources: mobile sources – such as cars buses planes trucks and trains. stationary sources – such as power plants oil refineries industrial facilities and factories. area sources – such as agricultural areas cities and wood burning fireplaces.
What is air pollution for Class 3?
When the air becomes dirty due to smoke and harmful gases it is called AIR POLLUTION. We should always breathe clean and fresh air because breathing impure or dirty air can make us sick and it can also harm the atmosphere.
What are the main causes of air pollution?
- The Burning of Fossil Fuels. …
- Agricultural Activities. …
- Waste in Landfills. …
- Exhaust From Factories and Industries. …
- Mining Operations. …
- Indoor Air Pollution. …
- Natural Events.
What are characteristics of mass?
What are the characteristics of an air mass when the air pressure is very high?
A high pressure system is colder air moving from the upper layers of the atmosphere towards the earth’s surface. The air is becoming more dense as it sinks and any water is vaporized into the air mass. There is no water to form clouds and the air is stable fair and dry.
What is the boundary between 2 air masses with different properties called?
Front: The boundary between two air masses of different density. When it does not move it’s called “stationary” “warm” when warmer air replaces cooler air “cold” when cooler air replaces warmer air.
