Answer 1

`\large\boxed{\tt See \ Below.}`

Step-by-step explanation:

`\textsf{We are asked what a \underline{Low Pressure} system is associated with.}`

`\large\underline{\textsf{What is a Low Pressure System?}}`

`\textsf{A Low Pressure System is a \underline{storm} system that pushes down on the Earth's}`

`\textsf{atmosphere in order to pull surrounding airmasses, and clouds towards it.}`

`\textsf{A Low Pressure system moves counterclockwise, rather a High Pressure System}`

`\textsf{moves clockwise.}`

`\large\underline{\textsf{How does a Low Pressure System work?}}`

`\textsf{Low Pressure Systems work by decreasing the amount of pressure they have in}`

`\textsf{order to bring airmasses more quickly to its center. The 2 airmasses are cold and}`

`\textsf{hot air, which can't mix. This is due to the airmasses having different densities.}`

`\textsf{Instead of mixing the airmasses together, a Low Pressure System instead pushes}`

`\textsf{the airmasses away, with the other. These are called \underline{Fronts}.}`

`\large\underline{\textsf{What are Fronts?}}`

`\textsf{Fronts are lines that show which way the wind is going, and the temperature}`

`\textsf{difference due to the wind pulling a different airmass to the low.}`

`\underline{\textsf{What types of Fronts are there?}}`

`\textsf{There are 4 types of fronts.}`

`\textsf{Cold Front - The Cold Airmass is pulled from the North, South of the low.}`

`\textsf{Heat Front - The Hot Airmass is pulled from the South, Parallel to or North of the}`

`\textsf{low.}`

`\textsf{Stationary Front - Similar to High Pressure, however it acts like a Cold Front and}`

`\textsf{a Heat Front. If the front is North of your location, then warm air is being pulled}`

`\textsf{to you. If you're North of the front, then colder air is being pulled to you, slowly.}`

`\textsf{*Occluded Front - This Front is uncommon as it's caused if the Cold Front catches}`

`\textsf{up with a Heat Front, hence pulling in more colder air than warmer air. The same}`

`\textsf{applies for heat occluded fronts, where it is the opposite.}`

`\textsf{When these 2 airmasses mix, it causes precipitation on the line of a cold front.}`

`\textsf{Because the cold airmass is fighting with the warm airmass, precipitation is made}`

`\textsf{when the Humid Air from the Heat Front fights with the Dry Air from the Cold Front.}`

`\textsf{This can at times cause Severe Thunderstorms, or possibly just a drizzle of rain.}`

`\large\underline{\textsf{Hence;}}`

`\textsf{Low Pressure Systems are systems that pull \boxed{\tt A. \ Warm \ Air} and \boxed{\tt B. \ Cold \ Air.}}`

`\textsf{When this happens, the 2 airmasses fight and this causes \boxed{\tt D. \ Clouds \ And \ Rain} to}`

`\textsf{form.}`
