Draw their observations of orographic lift. Orographic lifting occurs when elevated terrain's, such as mountains, act as barriers to the flow of air. As air ascends a mountain slope, adiabatic cooling often generates clouds and precipitation. Some of the rainiest places in the world are located on windward mountain slopes. In addition to providing the lift to render air unstable, mountains remove additional moisture in other ways.
Mountains retard the passage of storm systems.
This results in higher precipitation in mountainous regions. Teacher will set up demonstration outside with box, fan about two meters away and smoke bomb in porcelain dish in between fan and box. Students will observe the collection of smoke at the front side of the box and watch smoke rise up to the top of the box to illustrate Orographic Lift. Students will observe and record observations in student science journals. Teacher will dispose of smoke bomb and lead class discussion as to what Orographic Lift looks like.
