Air masses are large bodies of air that have similar temperature and humidity. These air masses are moved around the atmosphere by prevailing winds that blow in one direction. At the boundaries between air masses, weather fronts form. Weather fronts cause changes in the weather such as rain, storms and wind.

What must occur for air masses to form fronts quizlet?
What must occur for air masses to form fronts? They must collide with each other.
What are mass movements quizlet?
Mass movement is the movement of earth materials called regoilth down a slope under the influence of gravity.
How are fronts and air masses related quizlet?
The boundary between air masses; where air masses meet. Type of front formed when a COLD air mass pushes a WARM air mass and forces the warm air to rise. Type of front formed when a WARM air mass pushes a COLD air mass, forcing the warm air to slide over the cold air.
Air Masses
What is air mass simple definition?
An air mass is a large volume of air in the atmosphere that is mostly uniform in temperature and moisture. Air masses can extend thousands of kilometers in any direction, and can reach from ground level to the stratosphere—16 kilometers (10 miles) into the atmosphere.
What makes an air mass?
An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface.
What are the 5 types of air masses?
The air masses in and around North America include the continental arctic (cA), maritime polar (mP), maritime tropical (mT), continental tropical (cT), and continental polar (cP) air masses.

What can move air masses?
Once an air mass is formed, it is moved by global winds.
What are air masses quizlet?
Air Mass. An air mass is a huge body of air in the lower atmosphere that has similar temperature,humidity, and air pressure at given height.
What Are Weather Fronts And How Do They Affect Our Weather?
What contributes to the movement of air masses quizlet?
Air masses are formed by uneven heating and cooling of the Earth by the sun. This causes pressure differences in different areas of the globe. The movement of air masses is just the flow of high pressure air masses to low pressure areas. Air masses that form over frozen polar regions are very cold and dry.
What causes an air mass to rise?
AIR RISES FOR VARIOUS REASONS, some caused by differences in density between the air and its surroundings, and others a result of externally imposed factors, like a mountain. If an air parcel rises because atmospheric conditions are unstable, free convection results.
