    I know its hard to believe but This is not a Homework is a study guide NOT for a grade, made out of 120 questions which i already found 100 and this other 20 are the ones that I'm having trouble with. I already looked some of the answers but I'm not sure if they are correct and some i couldn't find. Our teacher made this questions hard to find there are several chapters mixed together randomly; even if you use the book. This is College level not High School

    I understand the rules and I knew this might happened, You don't have to help on all of them just some if you want.

    Ok I'll take your word for it and let my partner mod decide.

    This is my expertise so I thought they were pretty simple.

    I'll provide strong clues which should lead you to the correct answer for the few you didn't get.

    1. & 8, A counterclockwise atmospheric circulation in the Northern Hemisphere is known as a/an Answer_A

    A bit of mariner lore. In the Northern mid-latitudes; If you stand with your wind facing the wind direction, extend your arms storms...aka cyclone is in the direction of your left arm and heading your way.


    4. . Tornadoes, although erratic in their pathways, are always characterized by ________ pressure. Air is swirling towards the base of the tornado. Wind goes from high to low pressure.

    6. Relative humidity is "relative" to ________. If there is dew or dense fog the relative humidity is 100%.

    10. Is tricky and you'd get partial credit. For the best answer though consider that upper air divergence usually is associated with lower level convergence such as that associated with storminess.

    11. Land and valleys are usually cooler at night than their surroundings.

    13. Winds seldom directly follow the pressure gradient. There's friction, Coriolis and other forces.

    14. I don't agree with any of them. You'd have one large Hadley cell with surface winds from pole to equator in both Northern and Southern hemisphere.

    15. Your answer is true only if there's little Coriolis or friction.

    16. Temperature region which has the Westerlies is a large region with regular upper air patterns.

    17. What could trap molecules of Oxygen?

    18. Why is air pressure higher at low altitudes?

    19. And so close to Columbus day, who's ship was trapped in them. The sun was directly overhead at noon.

    20. I don't know. My guess is the shift is greatest where insolation has the greatest effect, which would be over land.

    my take on home work + similar questions is that i don't delete, but leave you totally at the mercy of the other members whether they want to help you or ignore you

    it appears you've been lucky on this occasion
