Atmospheric pressure - _________________ increases as the density of air increases., cause-and-effect - There is a ______________ relationship between altitude and atmospheric pressure., atmospheric pressure. - Torricelli's tube of mercury was the first barometer, a tool that is used to measure, weather and altitude - Atmospheric pressure at a given location depends on what?, cold air is denser than hot air - Why is atmospheric pressure higher when air is colder and lower when air is warmer?, air moving from a region of high pressure to a region of low pressure. - Wind is caused by, Increasing; increase - ______ the difference in atmospheric pressure causes wind speed to _________., by the direction from which it is blowing across Earth's surface - In addition to its speed, how else is wind described?, your own observations of wind. - In determining wind speed, the Beaufort Scale allows you to use, Animals use wind for transportation, and plants use it to spread pollen. - How does wind interact with the biosphere?, Air warmed by thermal energy transferred from your body is replaced with cooler air. - Why does blowing wind make you feel cooler?, moving materials, making waves, and increasing evaporation. - Wind interacts with the geosphere and hydrosphere by, the sun - What is the original source of the wind's energy?, a circular flow of air caused by rising warm air and falling cold air. - Areas of high and low pressure are connected by a pattern of, global convection cells - Large ___________ transfer energy from the warm equator to cooler, higher latitudes., prototypes, or working models, that can be used for testing. - To develop a design for a hang glider, Otto Lilienthal drew detailed plans and made, shortening the wings to hold up to stronger winds - Which would be a modification to a hang glider design?, winds in the atmosphere. - To improve the design of hang gliders, engineers need to understand, an iterative process of testing, modifying, retesting, and modifying again. - For each improvement in glider design, engineers follow, d warming up more quickly than water during the day and cooling off more slowly at night. - Where land and bodies of water meet, sea breezes and land breezes are wind patterns that are the result of,
