Uneven heating and cooling of Earth's surface produce various air masses which differ in density, humidity, and temperature. The origin, movement, and interaction of these air masses result in significant weather changes. Use U. S. weather maps to identify and describe air masses, fronts, and their movement. Compare and contrast the measurements to local and regional weather data. Assess adequacy of emergency planning procedures to respond to the damage which such storms can cause.
Ocean currents affect the weather and long term climatic patterns of a region.
Investigate the influence of the Atlantic Ocean on erosion of coastal areas, commerce, and the climate of Delaware. Examine maps of ocean currents and trace the origin and flow of such currents to explain the transport of heat energy. Speculate which currents have dominate influence on the Delaware coast. Technology and Applications 1. Sources of environmental pollution can be tracked using maps and satellite imagery.
