Question

How is precipitation related to high- and low-pressure air?

A.) Neither high- nor low-pressure systems lead to rain.


B.) Low-pressure systems lead to rain.


C.) High-pressure systems lead to rain.


D.) Both high- and low-pressure systems lead to rain.

Answer 1

`\large\boxed{\textsf{ B. Low-pressure systems lead to rain. }}`

Step-by-step explanation:

`\textsf{We are asked how precipitation is related to high- and low-pressure systems.}`

`\large\underline{\textsf{What is Precipitation?}}`

`\textsf{Precipitation is the precipitable water that falls out of clouds. Not formed by}`

`\textsf{itself, precipitation is often formed by \boxed{\textsf{low-pressure systems}.}}`

`\large\underline{\textsf{What are Pressure Systems?}}`

`\textsf{Pressure Systems are systems in the atmosphere that determine our weather.}`

`\textsf{There are 2 types of systems, high-pressure, and low-pressure.}`

`\underline{\textsf{High-pressure systems;}}`

`\textsf{High-pressure systems are systems that apply pressure onto the atmosphere.}`

`\textsf{These systems move clockwise, opposite of a Low-Pressure System.}`

`\textsf{Because there's applied pressure, everything in the atmosphere is pushed away}`

`\textsf{from this system. This usually results in Sunny, Dry Weather.}`

`\underline{\textsf{Low-pressure systems;}}`

`\textsf{Low-pressure systems are systems that release pressure from the atmosphere.}`

`\textsf{These systems move counter-clockwise, opposite of a High-Pressure System.}`

`\textsf{Because the pressure is released, this allows for everything in the atmosphere}`

`\textsf{to be pulled to this system. This usually results in cloudy, wet, and rainy weather.}`

`\textsf{Now that we know what precipitation, and what pressure systems are, we can}`

`\textsf{conclude that the final answer is B.}`

`\underline{\textsf{Why?}}`

`\textsf{For Precipitation to happen, a low-pressure system must exist to pull precipitable}`

`\textsf{water South of it to the core of the system. High-pressure systems are the exact}`

`\textsf{opposite, which means high-pressure systems are out of the answer choices. Thus,}`

`\textsf{concluding B since low-pressure systems lead to precipitation.}`

`\textsf{I will add 2 pictures including a High-Pressure system and a Low-Pressure System.}`
