Of the following physical properties of the atmosphere, which is/are true? Choose all that apply. View Available Hint(s) The air temperature is warmer near Earth's surface than in the upper part of the troposphere. Air always moves from high-pressure regions toward low-pressure regions. Low pressure at the surface is associated with rising air (movement away from the surface). Warm air holds more water vapor than cool air. Cool air is less dense than warm air, so cool air rises. The troposphere is heated from above because it is closer to the Sun at high altitudes.

Which of the following statements is/are true about the formation or movement of hurricanes? Choose all that apply. The cyclonic flow of air currents in a hurricane is a result of the Coriolis effect. The latent heat stored in water vapor provides the energy that fuels the storm. Hurricanes are storms that form over warm ocean water. Most hurricanes form along the equator. Hurricanes generally travel from the east toward the west because of the trade winds.

Which of the following statements about the Coriolis effect is correct? There is no Coriolis effect for objects moving due south from the equator. The Coriolis effect is strongest between the Tropics of Cancer and Capricorn. The magnitude of the Coriolis effect depends on how long the object is in motion. The maximum Coriolis effect is at the equator, and there is no Coriolis effect at the poles.

The magnitude of the Coriolis effect depends on how long the object is in motion.

Why are tropical cyclones not likely to occur in mid-latitude regions? Easterly tradewinds prevent cyclones from reaching the mid-latitudes. Westerly winds steer cyclones into cooler ocean water. The Coriolis effect weakens in the mid-latitudes and cannot sustain cyclonic winds. Continental Arctic air masses dominate climate in mid-latitude regions. Mid-latitude regions are typically not affected by maritime tropical air masses.

Westerly winds steer cyclones into cooler ocean water.
