True or false: the universe is made of galaxies coma galaxies contain Stars cover Stars may have planetary systems. The uneven heating causes temperature differences, which in turn cause air currents (wind) to develop, which then move heat from where there is more heat (higher temperatures) to where there is less heat (lower temperatures). Why is pressure so much higher close to the Earth's surface? True or False: The faster air moves, the higher the pressure. Air on surfaces with higher temperatures will then begin to rise because it is lighter (less dense). 2. False. The pressure exerted by the weight of air in the atmosphere on Earth. done clear. Horizonally the distribution of air pressure is influenced by the temperature of the air at a given place. A. Altitude. The highest pressure is at sea level where the density of the air molecules is the greatest. Understand how wind currents are generated and relate it with land breeze and sea breeze. Energy from the sun that reaches Earth is mostly in the form of visible light, infrared radiation, and _____ radiation. Air on surfaces with cooler temperatures sink (do not rise). Atmospheric pressure is determined by the amount of air directly above a person or object. True of False: Air pressure pushes in all directions. Air pressure can be understood with the help of certain activities. Cool, falling air is associated with low pressure areas. Because of the energy surplus at low latitudes for example, the air there is warmer than that at the poles. (p) Caused by high speed wind and air pressure differences. Question: True Or False: As A Parcel Of Air Ascends, It Expands Due To The Reduced Pressure Around The Parcel The Higher It Goes Above The Earth's Surface. Q. D) When air moves from low pressure to high pressure it is called wind. True or False. what term is used to describe the net-inward directed force found in symmetrically curved flow in the upper atmosphere? Differences in air pressure and the pressure gradient force are caused by the unequal heating of the Earth’s surface when incoming solar radiation concentrates at the equator. 4. D. How the atmosphere exerts pressure through air . This weight of air acting on a surface causes air pressure. What are the factors that affect air pressure? WHAT CAUSES WEATHER? Pressure. Differences in air temperature and air pressure due to uneven heating of the Earth creates? 52. 51. B. The environmental lapse rate in the troposphere is 6.5 degrees Celsius per 1,000 meters. 18.
