In this section you will find materials that support the implementation of EarthComm, Section 2: Weather Basics.
- Carry out investigations to explain the effects of different temperatures on the density of a volume of air.
- Analyze data on a map of the United States to identify regional air masses.
- Carry out an investigation that measures the elements that make up weather.
- Obtain information about the effects that result from the interaction of different types of air masses.
- To learn more about tracking weather events over time using a weather map, visit the following web site:

How and Why Warm Air Rises
Cloud Development and Stability, UCAR
Describes mechanisms that cause air to rise and form clouds. Also describes the outcome when air is also forced upward at areas of low pressure or when two airmasses collide.
Cloud Formation, UK Met Office
Describe cloud formation, including a video. In addition to surface heating, also describes the effects of topography, frontal contact, convergence, and turbulence on uplift.
Air Masses and Fronts
Air Masses, NOAA
Explains how air masses form, the principle classifications that influence the continental United States, and the formation of fronts between them.
Characteristics of the Atmosphere, Air Parcels and Air Masses, NASA
Scroll down to examine the characteristics of air masses, the lifting or rising of an air mass, air mass classification, and the direction of movement of major air masses.
How Clouds Form
Cloud Formation, UK Met Office
Describes cloud formation, including a video. In addition to surface heating, also describes the effects of topography, frontal contact, convergence, and turbulence on uplift.
The Importance of Understanding Clouds, NASA
Describe how clouds are an important regular of Earth's temperature.
Understanding Clouds and Fog, USA Today
Reviews how and where clouds typically form. Includes some graphics and additional links to help understand clouds.
Types of Clouds
Cloud Classification and Characteristics, NOAA
Examines the classification system for classifying clouds. Provides example pictures of each type.
Cloud Types, Windows to the Universe NESTA
Click on the cloud groups or cloud type of interest to view an image and relevant text.
Weather and the Water Cycle
The Water Cycle, NASA
Examines the role of water in the Earth system, including elements of weather.
