Jet streams, which are rapidly moving ribbons of air 6 to 9 miles above the Earth, influence the weather by separating warm and cold air and pushing weather systems around the globe. The movement of a jet stream affects temperatures and precipitation.

Answer:b) Reaction
Explanation:
Gwen is using Reaction Formation defense mechanism which got triggered when a person true feeling is not accepted by society or considered it illegal, so they convince others and themselves that the opposite is true.
They often exaggerate over the topic to prove their point. Though Gwen always wanted to be a clown but due the fact that her college roommate dislikes the clown so her reaction formation came into effect.

Answer:
B.The slinky descriptions of motion are switched.
Explanation:
First of all, let's define the two types of wave:
- Transverse wave: in a transverse wave, the oscillation of the wave occurs in a direction perpendicular to the direction of propagation of the wave. An example of transverse wave are electromagnetic waves.
- Longitudinal wave: in a longitudinal wave, the oscillation of the wave occurs in a direction parallel to the direction of propagation of the wave. An example of longitudinal wave are sound waves.
According to these definitions, we notice that the following descriptions of motion must be switched:
- "Like moving a spring up and down" --> this better describes a transverse wave, because the motion up/down is perpendicular to the direction of the spring
- "Like moving a spring back and forth" --> this better describes a longitudinal wave, because the back/forth motion is parallel to the direction of the spring
Answer:
When the volume increases or when the temperature decreases
Explanation:
The ideal gas equation states that:
where
p is the gas pressure
V is the volume
n is the number of moles of gas
R is the gas constant
T is the gas temperature
Assuming that we have a fixed amount of gas, so n is constant, we can rewrite the equation as
which means the following:
- Pressure is inversely proportional to the volume: this means that the pressure decreases when the volume increases
- Pressure is directly proportional to the temperature: this means that the pressure decreases when the temperature decreases
