Winds: Local & Global

What is Wind, and What Causes It? Use the Dropdowns to complete the paragraph. What is wind?Wind is air in motion. It is produced by the uneven heating of the earth’s surface by the sun. Since the earth’s surface is made of various land and water formations, it absorbs the sun’s radiation unevenly. The differences in heating create different regions of air pressure. High pressure systems consist of colder, heavier air. Low pressure systems have warmer, lighter air. Local Winds Sort each item into the correct category. Land Breeze Happens at night Happens because water holds heat longer than land Air is warmed by the ocean and rises which allows cool air over the land to move out to the ocean. Sea Breeze Happens during the day Happens because land heats up faster than water Air is warmed by the land and rises which allows cool air over the ocean to move over the land The Jet Stream Sort the Jet Stream Properties True Blow from West to East Can be located in the Upper Troposphere Jet streams can affect our weather by moving it from one place to another False Bands of mild wind Airplanes do not fly in the jet stream The path of the jet stream changes slowly over time
