Question

drag the tiles to the correct boxes to complete the pairs.
air masses are huge expanses of air that form from differential heating in the atmosphere. the boundary between two air masses is called a weather front. fronts can create particular types of weather. identify each front by the weather it produces.
warm stationary cold occluded
a cold air mass advances on a warm air mass, causing rain.
a warm air mass advances on a cold air mass, causing rain.
air masses that are close in temperature collide, typically leading to mild weather.
three air masses meet, usually leading to strong winds and heavy rain.

Explanation:

• For the first description: A cold air mass advancing on a warm air mass is characteristic of a cold front, which often brings rain.
• For the second: A warm air mass advancing on a cold one is a warm front, associated with rain.
• For the third: Air masses close in temperature colliding (little movement) describes a stationary front, leading to mild weather.
• For the fourth: Three air masses meeting (with an occluded front forming) leads to strong winds and heavy rain.

Answer:

• "A cold air mass advances on a warm air mass, causing rain." → cold
• "A warm air mass advances on a cold air mass, causing rain." → warm
• "Air masses that are close in temperature collide, typically leading to mild weather." → stationary
• "Three air masses meet, usually leading to strong winds and heavy rain." → occluded
