An air mass forms over the North Pole region describe what you think the temperature and humidity of this air mass will be like?
soldi70 [24.7K]

Answer: hope this helps :)

The motion of air mass motion is usually based upon the air flow in the upper atmosphere. As the jet stream changes intensity and position, it affects the motion and strength of air masses. Where air masses converge, they form boundaries called "fronts".

3-D view of a cold front.

Fronts are identified by change of temperature based upon their motion. With a cold front, a colder air mass is replacing a warmer air mass. A warm front is the opposite affect in that warm air replaces cold air. There is also a stationary front, which, as the name implies, means the boundary between two air masses does not move.

The motion of air masses also affects where a good portion of precipitation occurs. The air of cold air masses is more dense than warmer air masses. Therefore, as these cold air masses move, the dense air undercuts the warmer air masses forcing the warm air up and over the colder air causing it to rise into the atmosphere.

So, fronts just don't appear at the surface of the earth, they have a vertical structure or slope to them as well. Warm fronts typically have a gentle slope so the air rising along

Jenny predicts that when water in a cup evaporates, the mass of the water and cup together will get smaller.
Elden [556K]

A.  Use a scale to measure the mass of a cup of water. Leave the cup out for one day and measure the mass again.

Explanation:

Jenny can predict is evaporation occurs by using a weighing scale to measure that mass of a cup of water, then he leaves the cup out for one day and he measures the mass again.

  • If the mass remains the same, then evaporation did not occur.
  • If evaporation occurs, then the mass will be lesser after the second measurement.
  • From this Jenny can infer the mass loss and made good deductions.
  • Evaporation is a phase change in which liquid turns to vapor.
