  1. You have come to the right website. I actually aced the regents :3

    36- The Symbols CP and MT mean Continental Polar and Maritime Tropical.

    Continental = Dry Air

    Maritime= Humid Air

    Polar= Cold

    Tropical= Warm

    H= High Pressure Center, Turns counterclockwise and outward

    L= Low Pressure Center, Turns Clockwise and inward

    ^Very important Remember that^

    Because the MT airmass *marked by the symbol between the two lines* Is surrounded by CP airmasses That means that the frontal boundary on the right brings in the MT airmass and the one on the left brings in the CP airmass.

    Because it is centered around a Low Pressure center, or Cyclone, That means that it moves from west to east *as most  airmasses, fronts and storm systems in NYS do*

    Answer: 2. Because it shows the correct leading edges, in the correct direction. *whichever side the symbols are on is the way the front moves. If they are on both sides, it is stationary*

    39- What is March 21st in NYS? Please say the Vernal Equinox.

    You said it? Good!

    The vernal Equinox means that the hours of the day are balanced between day and night perfetcly. This means that the shadows of equal times will be the same. *11 is the same shadow length as 1,  10 with 2 ans so on*

    Answer: 1- The shadow is the same angle and length as 10, it's mirror hour from noon *both are 2 hours from noon, hence they 'mirror' themselves*

    81- You need your ESRT *earth Science Reference table* for this one. All you need to do is find those fossil images *they should be exactly the same* on that big-huge chart about the various eras of the planet and the index fossils. Then look at the chart on the same page that indicates when they existed, and place-a-roo them on the answer sheet.

    *My ESRT is way too old to give you a direct answer for this one*

    Study your hardest, and good luck.
