Answer:
Fronts are defined as body of two air masses and are of four types.
Explanation:
Air masses always be in motion which brings different types of weather. Transition between the two air masses is a front.Basically there are four different types of fronts and the weather which are associated with them also varies.
So the four fronts are:
- WARM FRONT: It has a wide range from 10-100km.Winds move easterly before the front passes.Chances of rainfall increases when the front cloud approaches . And the wind starts blowing southwesterly or southerly and then the temperature becomes warm with the clouds cleared. Has a huge amount of humidity.
- COLD FRONT: It is narrow down to a range of <1km.Over a short distance Temperature changes when cold air advances and warm air displaces.Moisture change also causes sharply. At the ahead of the front their is higher moisture content and behind it is lower.
- OCCLUDED FRONT: When a cold front catches up with a warm front. Their are both cold and warm occulusions. In a warm occulusion colder air is found behind the front and conversely in cold occulusion warmer air is found at the front end. Winds blow either fromsouth or east. And then it gets shifted from west or northwest.
- STATIONARY FRONT: Boundary between warmer and colder front doesn't move. Precipitation may get developed.
- Finally the context of midlatitude cyclogenesis leads to understanding the different type of fronts which helps us to know the kind of weather and the knowledge help us to predict how the areas near the fronts will be impacted regardless of precipitation' wind and temperature.
Answer:
From what I know, compasses and other magnetic things would not work.
Explanation:
According
to studies, drivers ranging from 16- to 20-years old with a blood-alcohol level
of .02 percent to .049 percent had almost a three times higher risk of being
involved in a fatal crash than sober drivers of similar age. Their chances of
dying in a single-vehicle crash were almost four times greater. It also showed
the risk of a fatal car crash doubled for sober male drivers between 1996 and
2007. The researchers said unfocused driving may well be the cause. The
researchers settled that drunk-driving and distracted-driving prevention
education is needed for both boys and girls.
