An air parcel is considered unstable when it

Question 1 An air parcel is considered unstable when it… Group of answer choices 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. Question 2 Relative humidity is… Group of answer choices 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 . Question 3 Sea breezes are caused by… Group of answer choices 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. Question 4 The Coriolis force cannot change the speed of the wind. Group of answer choices True False Question 5 Subsidence is most closely associated with high-pressure conditions. True False Question 6 Earth’s average albedo is 39%. True False Question 7 A counterclockwise flow in the Southern Hemisphere is associated with a low-pressure system. True False Question 8 Out of the three forces that cause wind, which force is mostly absent in the upper troposphere and
WHY? Group of answer choices 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. Question 9 The specific heat of water is greater than that of land. This means… Group of answer choices 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. Question 10 Based on a posted video, the TIV was used to do the following: Group of answer choices 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 Question 1 1 pts An air parcel is considered unstable when it... either remains as it is, or changes its initial position. ceQuestion 2 1 pts Relative humidity is... the amount of water vapor in the air compared to the average amount. the amount of mQuestion 3 1 pts Sea breezes are caused by... onshore (toward the land) air flows that develop in the afternoon as the land hQuestion 4 1 pts The Coriolis force cannot change the speed of the wind.

Answer

1)- Unstable Air Parcel- when an air parcel continues to rise unti it reach altitude at which the surrounding air has a similar density and temperatures. When air cease to ascend if become stable. When air parcel resistance displacement it is stable. 2.- Relative Humidity- The amount of water vapour in the air compared to maximum amount at given temperatures . It is inversely proportionally to temperature.. 3.-Sea breezes are caused by – Onshore (toward the land ) air flow that develop in the afternoon as the land heat faster than neighbors water surface. 4.- True – corilis force cannot change the speed of wind because corilis force change the direction of wind Right in north hemisphere and Left in south hemisphere. 5- True- Subsidence is associated with High pressure area for example Sub Tropical high pressure zone is associated with subsidence of air at 25 -35 degrees latitude. 6-False – Earth albedo is about – 30 – 35 percent. 7- False – counterclockwise flow in south hemisphere is associated with high pressure area. 8- Frictional force because wind at this ( upper atmospheric) far enough away from the earth surfaces. 9.- water absorb and cool more slowly than land

10- TIV used for capture video for an IMX movie about tornadoes.
