Question 1 1 pts An air parcel is considered unstable when it... either remains as it is, or changes its initial position. ceases to ascend. resists displacement upward. continues to rise until it reaches an altitude at which the surrounding air has a similar density or temperature. Next → Question 2 1 pts Relative humidity is... the amount of water vapor in the air compared to the average amount. the amount of moisture in the air relative to your own sensible feelings. a basically unused concept when it comes to weather topics. the amount of water vapor in the air compared to the maximum amount at a given temperature. • Previous Next → Question 3 1 pts Sea breezes are caused by... onshore (toward the land) air flows that develop in the afternoon as the land heats faster than neighboring water surfaces. the fact that warmer air is denser and settles to the surface of the land. the fact that land heats and cools more slowly than water. cooler air flowing offshore (toward the ocean) in the afternoon. • Previous Next Question 4 1 pts The Coriolis force cannot change the speed of the wind. True False • Previous Next → Question 5 1 pts Subsidence is most closely associated with high-pressure conditions. True False Previous Next → Question 6 1 pts Earth's average albedo is 39%. True False - Previous Next → Question 7 1 pts A counterclockwise flow in the Southern Hemisphere is associated with a low-pressure system. True False Previous Next → Question 8 1 pts Out of the three forces that cause wind, which force is mostly absent in the upper troposphere and WHY? Friction, because wind at this level feels the Earth's surface Coriolis, because wind at this level is far enough away from the Earth's surface. Friction, because wind at this level is far enough away from the Earth's surface. Coriolis, because wind at this level feels the Earth's surface. • Previous Next → Question 9 1 pts The specific heat of water is greater than that of land. This means.. None of these choices is true. land is warmer than water. land cools more slowly than does water. water cools more slowly than does land. • Previous Next → Question 10 1 pts Based on a posted video, the TIV was used to do the following: Understand wind gusts in a hurricane Capture video for an IMAX movie about tornadoes Study the Earth's radiation balance Measure dew point temperature and relative humidity Previous
